|
|
+ * @description
|
|
|
+ *
|
|
|
+ * This object provides a utility for producing rich Error messages within
|
|
|
+ * Angular. It can be called as follows:
|
|
|
+ *
|
|
|
+ * var exampleMinErr = minErr('example');
|
|
|
+ * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
|
|
|
+ *
|
|
|
+ * The above creates an instance of minErr in the example namespace. The
|
|
|
+ * resulting error will have a namespaced error code of example.one. The
|
|
|
+ * resulting error will replace {0} with the value of foo, and {1} with the
|
|
|
+ * value of bar. The object is not restricted in the number of arguments it can
|
|
|
+ * take.
|
|
|
+ *
|
|
|
+ * If fewer arguments are specified than necessary for interpolation, the extra
|
|
|
+ * interpolation markers will be preserved in the final string.
|
|
|
+ *
|
|
|
+ * Since data will be parsed statically during a build step, some restrictions
|
|
|
+ * are applied with respect to how minErr instances are created and called.
|
|
|
+ * Instances should have names of the form namespaceMinErr for a minErr created
|
|
|
+ * using minErr('namespace') . Error codes, namespaces and template strings
|
|
|
+ * should all be static strings, not variables or general expressions.
|
|
|
+ *
|
|
|
+ * @param {string} module The namespace to use for the new minErr instance.
|
|
|
+ * @param {function} ErrorConstructor Custom error constructor to be instantiated when returning
|
|
|
+ * error from returned function, for cases when a particular type of error is useful.
|
|
|
+ * @returns {function(code:string, template:string, ...templateArgs): Error} minErr instance
|

|
|
|

|
|
|
+ * the jquery variable under window (eg. jQuery).
|
|
|
+ *
|
|
|
+ * Since angular looks for this directive when it is loaded (doesn't wait for the

|
|
+ * DOMContentLoaded event), it must be placed on an element that comes before the script
|
|
|
+ * which loads angular. Also, only the first instance of `ng-jq` will be used and all
|
|
|
+ * others ignored.
|
|
|
+ *
|
|
|
+ * @example
|
|
|
+ * This example shows how to force jqLite using the `ngJq` directive to the `html` tag.
|
|

|
|
|
+ * @description
|
|
|
+ *
|
|
|
+ * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
|
|
|
+ * designates the **root element** of the application and is typically placed near the root element
|
|
|
+ * of the page - e.g. on the `<body>` or `<html>` tags.
|
|
|
+ *
|
|
|
+ * There are a few things to keep in mind when using `ngApp`:
|
|
|
+ * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
|
|
|
+ * found in the document will be used to define the root element to auto-bootstrap as an
|
|
|
+ * application. To run multiple applications in an HTML document you must manually bootstrap them using
|
|
|
+ * {@link angular.bootstrap} instead.
|
|
|
+ * - AngularJS applications cannot be nested within each other.
|
|
|
+ * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
|
|
|
+ * This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
|
|
|
+ * {@link ngRoute.ngView `ngView`}.
|
|
|
+ * Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
|
|
|
+ * causing animations to stop working and making the injector inaccessible from outside the app.
|
|
|
+ *
|
|
|
+ * You can specify an **AngularJS module** to be used as the root module for the application. This
|
|
|
+ * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
|
|
|
+ * should contain the application code needed or have dependencies on other modules that will
|
|
|
+ * contain the code. See {@link angular.module} for more information.
|
|
|
+ *
|
|
|
+ * In the example below if the `ngApp` directive were not placed on the `html` element then the
|
|
|
+ * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
|
|
|
+ * would not be resolved to `3`.
|
|
|
+ *
|
|
|
+ * `ngApp` is the easiest, and most common way to bootstrap an application.

|
|
|
+ * each of the subsequent scripts. This prevents strange results in applications, where otherwise
|
|
|
+ * multiple instances of Angular try to work on the DOM.
|

|
|
|
+ * The `angular.module` is a global place for creating, registering and retrieving Angular
|
|
|
+ * modules.
|
|
|
+ * All modules (angular core or 3rd party) that should be available to an application must be
|
|
|
+ * registered using this mechanism.
|
|
|
+ *
|
|
|
+ * Passing one argument retrieves an existing {@link angular.Module},
|
|
|
+ * whereas passing more than one argument creates a new {@link angular.Module}
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * # Module
|
|
|
+ *
|
|
|
+ * A module is a collection of services, directives, controllers, filters, and configuration information.
|
|
|
+ * `angular.module` is used to configure the {@link auto.$injector $injector}.
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * // Create a new module
|
|
|
+ * var myModule = angular.module('myModule', []);
|
|
|
+ *
|
|
|
+ * // register a new service
|
|
|
+ * myModule.value('appName', 'MyCoolApp');
|
|
|
+ *
|
|
|
+ * // configure existing services inside initialization blocks.
|
|
|
+ * myModule.config(['$locationProvider', function($locationProvider) {
|
|
|
+ * // Configure existing providers
|
|
|
+ * $locationProvider.hashPrefix('!');
|
|
|
+ * }]);
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * Then you can create an injector and load your modules like this:
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * var injector = angular.injector(['ng', 'myModule'])
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * However it's more likely that you'll just use
|
|
|
+ * {@link ng.directive:ngApp ngApp} or
|
|
|
+ * {@link angular.bootstrap} to simplify this process for you.
|
|
|
+ *
|
|
|
+ * @param {!string} name The name of the module to create or retrieve.
|
|
|
+ * @param {!Array.<string>=} requires If specified then new module is being created. If
|
|
|
+ * unspecified then the module is being retrieved for further configuration.
|
|
|
+ * @param {Function=} configFn Optional configuration function for the module. Same as
|
|
|
+ * {@link angular.Module#config Module#config()}.
|
|
|
+ * @returns {angular.Module} new module with the {@link angular.Module} api.

|

|
|
|

|
|
|
+ * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
|
|
|
+ *
|
|
|
+ * If jQuery is available, `angular.element` is an alias for the
|
|
|
+ * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
|
|
|
+ * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
|
|
|
+ *
|
|
|
+ * jqLite is a tiny, API-compatible subset of jQuery that allows
|
|
|
+ * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
|
|
|
+ * commonly needed functionality with the goal of having a very small footprint.
|
|
|
+ *
|
|
|
+ * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
|
|
|
+ * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
|
|
|
+ * specific version of jQuery if multiple versions exist on the page.
|
|
|
+ *
|
|
|
+ * <div class="alert alert-info">**Note:** All element references in Angular are always wrapped with jQuery or
|
|
|
+ * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.</div>
|
|
|
+ *
|
|
|
+ * <div class="alert alert-warning">**Note:** Keep in mind that this function will not find elements
|
|
|
+ * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
|
|
|
+ * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.</div>
|
|
|
+ *
|
|
|
+ * ## Angular's jqLite
|
|
|
+ * jqLite provides only the following jQuery methods:
|
|
|
+ *
|
|
|
+ * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
|
|
|
+ * - [`after()`](http://api.jquery.com/after/)
|
|
|
+ * - [`append()`](http://api.jquery.com/append/)
|
|
|
+ * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
|
|
|
+ * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData
|
|
|
+ * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
|
|
|
+ * - [`clone()`](http://api.jquery.com/clone/)
|
|
|
+ * - [`contents()`](http://api.jquery.com/contents/)
|
|
|
+ * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
|
|
|
+ * As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
|
|
|
+ * - [`data()`](http://api.jquery.com/data/)
|
|
|
+ * - [`detach()`](http://api.jquery.com/detach/)
|
|
|
+ * - [`empty()`](http://api.jquery.com/empty/)
|
|
|
+ * - [`eq()`](http://api.jquery.com/eq/)
|
|
|
+ * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
|
|
|
+ * - [`hasClass()`](http://api.jquery.com/hasClass/)
|
|
|
+ * - [`html()`](http://api.jquery.com/html/)
|
|
|
+ * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
|
|
|
+ * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
|
|
|
+ * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
|
|
|
+ * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
|
|
|
+ * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors

+ * - [`prepend()`](http://api.jquery.com/prepend/)
|
|
|
+ * - [`prop()`](http://api.jquery.com/prop/)
|
|
|
+ * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)
|
|
|
+ * - [`remove()`](http://api.jquery.com/remove/)
|
|
|
+ * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes
|
|
|
+ * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
|
|
|
+ * - [`removeData()`](http://api.jquery.com/removeData/)
|
|
|
+ * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
|
|
|

|
|
+ * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
|

|
|

|
|
|
+ * ## jQuery/jqLite Extras
|
|
|
+ * Angular also provides the following additional methods and events to both jQuery and jqLite:
|
|
|
+ *
|
|
|
+ * ### Events
|
|
|
+ * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
|
|
|
+ * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM
|
|
|
+ * element before it is removed.
|
|
|
+ *
|
|
|
+ * ### Methods
|
|
|
+ * - `controller(name)` - retrieves the controller of the current element or its parent. By default
|
|
|
+ * retrieves controller associated with the `ngController` directive. If `name` is provided as
|
|
|
+ * camelCase directive name, then the controller for this directive will be retrieved (e.g.
|
|
|
+ * `'ngModel'`).
|
|
|
+ * - `injector()` - retrieves the injector of the current element or its parent.
|
|
|
+ * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
|
|
|
+ * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
|
|
|
+ * be enabled.
|
|
|
+ * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
|
|
|
+ * current element. This getter should be used only on elements that contain a directive which starts a new isolate
|
|
|
+ * scope. Calling `scope()` on this element always returns the original non-isolate scope.
|
|
|
+ * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
|
|
|
+ * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
|
|
|
+ * parent element is reached.
|
|
|
+ *
|
|
|
+ * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
|
|
|
+ * https://github.com/angular/angular.js/issues/14251 for more information.
|
|
|
+ *
|
|
|
+ * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
|
|
|
+ * @returns {Object} jQuery object.

|
|
|
+ * dependency injection (see {@link guide/di dependency injection}).
|
|
|
+ *
|
|
|
+ * @param {Array.<string|Function>} modules A list of module functions or their aliases. See
|
|
|
+ * {@link angular.module}. The `ng` module must be explicitly added.
|
|
|
+ * @param {boolean=} [strictDi=false] Whether the injector should be in strict mode, which
|
|
|
+ * disallows argument name annotation inference.
|
|
|
+ * @returns {injector} Injector object. See {@link auto.$injector $injector}.
|
|
|
+ *
|
|
|
+ * @example
|
|
|
+ * Typical usage
|
|
|
+ * ```js
|
|
|
+ * // create an injector
|
|
|
+ * var $injector = angular.injector(['ng']);
|
|
|
+ *
|
|
|
+ * // use the injector to kick off your application
|
|
|
+ * // use the type inference to auto inject arguments, or use implicit injection
|
|
|
+ * $injector.invoke(function($rootScope, $compile, $document) {
|
|
|
+ * $compile($document)($rootScope);
|
|
|
+ * $rootScope.$digest();
|
|
|
+ * });
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * Sometimes you want to get access to the injector of a currently running Angular app
|
|
|
+ * from outside Angular. Perhaps, you want to inject and compile some markup after the
|
|
|
+ * application has been bootstrapped. You can do this using the extra `injector()` added
|
|
|
+ * to JQuery/jqLite elements. See {@link angular.element}.
|
|
|
+ *
|
|
|
+ * *This is fairly rare but could be the case if a third party library is injecting the
|
|
|
+ * markup.*
|
|
|
+ *
|
|
|
+ * In the following example a new block of HTML containing a `ng-controller`
|
|
|
+ * directive is added to the end of the document body by JQuery. We then compile and link
|
|
|
+ * it into the current AngularJS scope.
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>');
|
|
|
+ * $(document.body).append($div);
|
|
|
+ *
|
|
|
+ * angular.element(document).injector().invoke(function($compile) {
|
|
|
+ * var scope = angular.element($div).scope();
|
|
|
+ * $compile($div)(scope);
|
|
|
+ * });
|

+ * # Injection Function Annotation
|
|
|
+ *
|
|
|
+ * JavaScript does not have annotations, and annotations are needed for dependency injection. The
|
|
|
+ * following are all valid ways of annotating function with injection arguments and are equivalent.
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * // inferred (only works if code not minified/obfuscated)
|
|
|
+ * $injector.invoke(function(serviceA){});
|
|
|
+ *
|
|
|
+ * // annotated
|
|
|
+ * function explicit(serviceA) {};
|
|
|
+ * explicit.$inject = ['serviceA'];
|
|

+ * $injector.invoke(explicit);
|
|
|
+ *
|
|
|
+ * // inline
|
|
|
+ * $injector.invoke(['serviceA', function(serviceA){}]);
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * ## Inference
|
|
|
+ *
|
|
|
+ * In JavaScript calling `toString()` on a function returns the function definition. The definition
|
|
|
+ * can then be parsed and the function arguments can be extracted. This method of discovering
|
|
|
+ * annotations is disallowed when the injector is in strict mode.
|
|
|
+ * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
|
|
|
+ * argument names.
|
|
|
+ *
|
|
|
+ * ## `$inject` Annotation
|
|
|
+ * By adding an `$inject` property onto a function the injection parameters can be specified.
|
|
|
+ *
|
|
|
+ * ## Inline
|
|
|
+ * As an array of injection names, where the last item in the array is the function to call.

|

+ * dependencies.
|
|
|
+ *
|
|
|
+ * # Argument names
|
|
|
+ *
|
|
|
+ * The simplest form is to extract the dependencies from the arguments of the function. This is done
|
|
|
+ * by converting the function into a string using `toString()` method and extracting the argument
|
|
|
+ * names.
|
|
|
+ * ```js
|
|
|
+ * // Given
|

+ * function MyController($scope, $route) {

|
+ * // Then
|
|
|
+ * expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * You can disallow this method by using strict injection mode.
|
|
|
+ *
|
|
|
+ * This method does not work with code minification / obfuscation. For this reason the following
|
|
|
+ * annotation strategies are supported.
|
|
|
+ *
|
|
|
+ * # The `$inject` property
|
|
|
+ *
|
|
|
+ * If a function has an `$inject` property and its value is an array of strings, then the strings
|
|
|
+ * represent names of services to be injected into the function.
|
|
|
+ * ```js
|

|

|

|
|
|

|

|
|
|
+ * injector.invoke(function($compile, $rootScope) {
|
|
|
+ * // ...
|
|
|
+ * });
|
|
|
+ *
|
|
|
+ * // We are forced to write break inlining
|
|
|
+ * var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
|
|
|
+ * // ...
|
|
|
+ * };
|
|
|
+ * tmpFn.$inject = ['$compile', '$rootScope'];
|
|
|
+ * injector.invoke(tmpFn);
|
|
|
+ *
|
|
|
+ * // To better support inline function the inline annotation is supported
|
|
|
+ * injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
|
|
|
+ * // ...
|
|

|

|

|
|
|
+ * ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
|

+ * ).toEqual(['$compile', '$rootScope']);
|

|

|

|
|
|
+ *
|
|
|
+ * The {@link auto.$provide $provide} service has a number of methods for registering components
|
|
|
+ * with the {@link auto.$injector $injector}. Many of these functions are also exposed on
|
|
|
+ * {@link angular.Module}.
|
|
|
+ *
|
|
|
+ * An Angular **service** is a singleton object created by a **service factory**. These **service
|
|
|
+ * factories** are functions which, in turn, are created by a **service provider**.
|
|
|
+ * The **service providers** are constructor functions. When instantiated they must contain a
|
|
|
+ * property called `$get`, which holds the **service factory** function.
|
|
|
+ *
|
|
|
+ * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
|
|
|
+ * correct **service provider**, instantiating it and then calling its `$get` **service factory**
|
|
|
+ * function to get the instance of the **service**.
|
|
|
+ *
|
|
|
+ * Often services have no configuration options and there is no need to add methods to the service
|
|
|
+ * provider. The provider will be no more than a constructor function with a `$get` property. For
|
|
|
+ * these cases the {@link auto.$provide $provide} service has additional helper methods to register
|
|
|
+ * services without specifying a provider.
|
|
|
+ *
|
|
|
+ * * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the
|
|
|
+ * {@link auto.$injector $injector}
|
|
|
+ * * {@link auto.$provide#constant constant(name, obj)} - registers a value/object that can be accessed by
|
|
|
+ * providers and services.
|
|
|
+ * * {@link auto.$provide#value value(name, obj)} - registers a value/object that can only be accessed by
|
|
|
+ * services, not providers.
|
|
|
+ * * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function**
|
|
|
+ * that will be wrapped in a **service provider** object, whose `$get` property will contain the
|
|
|
+ * given factory function.
|
|
|
+ * * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
|
|
|
+ * that will be wrapped in a **service provider** object, whose `$get` property will instantiate
|
|
|
+ * a new object using the given constructor function.
|
|
|
+ * * {@link auto.$provide#decorator decorator(name, decorFn)} - registers a **decorator function** that
|
|
|
+ * will be able to modify or replace the implementation of another service.
|
|
|
+ *
|
|
|
+ * See the individual methods for more information and examples.

|
|
|
+ *
|
|
|
+ * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
|
|
|
+ * are constructor functions, whose instances are responsible for "providing" a factory for a
|
|
|
+ * service.
|
|
|
+ *
|
|
|
+ * Service provider names start with the name of the service they provide followed by `Provider`.
|
|
|
+ * For example, the {@link ng.$log $log} service has a provider called
|
|
|
+ * {@link ng.$logProvider $logProvider}.
|
|
|
+ *
|
|
|
+ * Service provider objects can have additional methods which allow configuration of the provider
|
|
|
+ * and its service. Importantly, you can configure what kind of service is created by the `$get`
|
|
|
+ * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
|
|
|
+ * method {@link ng.$logProvider#debugEnabled debugEnabled}
|
|
|
+ * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
|
|
|
+ * console or not.
|
|
|
+ *
|
|
|
+ * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
|
|
|
+ 'Provider'` key.
|
|
|
+ * @param {(Object|function())} provider If the provider is:
|
|
|
+ *
|
|
|
+ * - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
|
|
|
+ * {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
|
|
|
+ * - `Constructor`: a new instance of the provider will be created using
|
|
|
+ * {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
|

|
|
|
+ * - **number**: A fixed number of pixels to be used as offset.<br /><br />
|
|
|
+ * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
|
|
|
+ * a number representing the offset (in pixels).<br /><br />
|
|
|
+ * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
|
|
|
+ * the top of the page to the element's bottom will be used as offset.<br />
|
|
|
+ * **Note**: The element will be taken into account only as long as its `position` is set to
|
|
|
+ * `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
|
|
|
+ * their height and/or positioning according to the viewport's size.

|
|
|

|
|
|

|
|
|
+ *
|
|
|
+ * Adding via the `script` tag:
|
|
|
+ *
|
|
|
+ * ```html
|
|
|
+ * <script type="text/ng-template" id="templateId.html">
|
|
|
+ * <p>This is the content of the template</p>
|
|
|
+ * </script>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * **Note:** the `script` tag containing the template does not need to be included in the `head` of
|
|
|
+ * the document, but it must be a descendent of the {@link ng.$rootElement $rootElement} (IE,
|
|
|
+ * element with ng-app attribute), otherwise the template will be ignored.
|
|
|
+ *
|
|
|
+ * Adding via the `$templateCache` service:
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * var myApp = angular.module('myApp', []);
|
|
|
+ * myApp.run(function($templateCache) {
|
|
|
+ * $templateCache.put('templateId.html', 'This is the content of the template');
|
|
|
+ * });
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * To retrieve the template later, simply use it in your component:
|
|
|
+ * ```js
|
|
|
+ * myApp.component('myComponent', {
|
|
|
+ * templateUrl: 'templateId.html'
|
|
|
+ * });
|
|
|

|
|
|
+ *
|
|
|

|
|
|
+ * ```js
|
|
|

|
|
|

|
|
|

|
|
|
+ *
|
|
|
+ * The difference resides in the return value of the factory function.
|
|
|
+ * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
|
|
|
+ * that defines the directive properties, or just the `postLink` function (all other properties will have

|
|
+ * the default values).
|
|
|
+ *
|
|
|
+ * <div class="alert alert-success">
|
|
|
+ * **Best Practice:** It's recommended to use the "directive definition object" form.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * Here's an example directive declared with a Directive Definition Object:
|
|
|

|
|
|
+ * ```js
|
|
|
+ * var myModule = angular.module(...);
|
|
|
+ *
|
|
|
+ * myModule.directive('directiveName', function factory(injectables) {
|
|
|
+ * var directiveDefinitionObject = {
|
|
|
+ * {@link $compile#-priority- priority}: 0,
|
|
|
+ * {@link $compile#-template- template}: '<div></div>', // or // function(tElement, tAttrs) { ... },
|
|
|
+ * // or
|
|
|
+ * // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },
|
|
|

|
|
|
+ * {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {

|
+ * {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
|
|
|
+ * }
|
|
|
+ * // or
|
|

|
|

+ * // {@link $compile#-link- link}: function postLink( ... ) { ... }
|
|
|
+ * };
|
|
|
+ * return directiveDefinitionObject;
|
|

+ * ```
|
|
|
+ *
|
|
|
+ * <div class="alert alert-warning">
|
|
|
+ * **Note:** Any unspecified options will use the default value. You can see the default values below.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * Therefore the above can be simplified as:
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * var myModule = angular.module(...);
|
|
|
+ *
|
|

|
|
|
+ * var directiveDefinitionObject = {
|
|
|
+ * link: function postLink(scope, iElement, iAttrs) { ... }
|
|
|
+ * };
|
|
|
+ * return directiveDefinitionObject;
|
|
|
+ * // or
|
|
|
+ * // return function postLink(scope, iElement, iAttrs) { ... }
|
|
|
+ * });
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * ### Life-cycle hooks
|
|
|
+ * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the
|
|
|
+ * directive:
|
|
|
+ * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
|
|
|
+ * had their bindings initialized (and before the pre & post linking functions for the directives on
|
|
|
+ * this element). This is a good place to put initialization code for your controller.
|
|
|
+ * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
|
|
|
+ * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
|
|
|
+ * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
|
|
|
+ * component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will
|
|
|
+ * also be called when your bindings are initialized.
|
|
|
+ * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
|
|
|
+ * changes. Any actions that you wish to take in response to the changes that you detect must be
|
|
|
+ * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
|
|
|
+ * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
|
|
|
+ * be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
|
|
|
+ * if detecting changes, you must store the previous value(s) for comparison to the current values.
|
|
|
+ * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
|
|
|
+ * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
|
|
|
+ * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
|
|
|
+ * components will have their `$onDestroy()` hook called before child components.
|
|
|
+ * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
|
|
|
+ * function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
|
|
|
+ * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
|
|
|
+ * they are waiting for their template to load asynchronously and their own compilation and linking has been
|
|
|
+ * suspended until that occurs.
|
|
|
+ *
|
|
|
+ * #### Comparison with Angular 2 life-cycle hooks
|
|
|
+ * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are
|
|
|
+ * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:
|
|
|
+ *
|
|
|
+ * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.
|
|
|
+ * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.
|
|
|
+ * In Angular 2 you can only define hooks on the prototype of the Component class.
|
|
|
+ * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to
|
|
|
+ * `ngDoCheck` in Angular 2
|
|
|
+ * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
|
|
|
+ * propagated throughout the application.
|
|
|
+ * Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
|
|
|
+ * error or do nothing depending upon the state of `enableProdMode()`.
|
|
|
+ *
|
|
|
+ * #### Life-cycle hook examples
|
|
|
+ *
|
|
|
+ * This example shows how you can check for mutations to a Date object even though the identity of the object
|
|
|
+ * has not changed.
|
|
|
+ *
|
|
|
+ * <example name="doCheckDateExample" module="do-check-module">
|
|
|
+ * <file name="app.js">
|
|
|
+ * angular.module('do-check-module', [])
|
|
|
+ * .component('app', {
|
|
|
+ * template:
|
|
|
+ * 'Month: <input ng-model="$ctrl.month" ng-change="$ctrl.updateDate()">' +
|
|
|
+ * 'Date: {{ $ctrl.date }}' +
|
|
|
+ * '<test date="$ctrl.date"></test>',
|
|
|
+ * controller: function() {
|
|
|
+ * this.date = new Date();
|
|
|
+ * this.month = this.date.getMonth();
|
|
|
+ * this.updateDate = function() {
|
|
|
+ * this.date.setMonth(this.month);
|
|
|
+ * };
|
|
|
+ * }
|
|
|
+ * })
|
|
|
+ * .component('test', {
|
|
|
+ * bindings: { date: '<' },
|
|
|
+ * template:
|
|
|
+ * '<pre>{{ $ctrl.log | json }}</pre>',
|
|
|
+ * controller: function() {
|
|
|
+ * var previousValue;
|
|
|
+ * this.log = [];
|
|
|
+ * this.$doCheck = function() {
|
|
|
+ * var currentValue = this.date && this.date.valueOf();
|
|
|
+ * if (previousValue !== currentValue) {
|
|
|
+ * this.log.push('doCheck: date mutated: ' + this.date);
|
|
|
+ * previousValue = currentValue;
|
|
|
+ * }
|
|
|
+ * };
|
|
|
+ * }
|
|
|
+ * });

|

|
|
|

|
|
|
+ *
|
|
|
+ * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
|
|
|
+ * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
|
|
|
+ * arrays or objects can have a negative impact on your application performance)

|
|
+ * ### Directive Definition Object
|
|
|
+ *
|
|
|
+ * The directive definition object provides instructions to the {@link ng.$compile
|
|
|
+ * compiler}. The attributes are:
|
|
|
+ *
|
|
|
+ * #### `multiElement`
|
|
|
+ * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between
|
|
|
+ * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
|
|
|
+ * together as the directive elements. It is recommended that this feature be used on directives
|
|
|
+ * which are not strictly behavioral (such as {@link ngClick}), and which
|
|
|
+ * do not manipulate or replace child nodes (such as {@link ngInclude}).
|
|
|
+ *
|
|
|
+ * #### `priority`
|
|
|
+ * When there are multiple directives defined on a single DOM element, sometimes it
|
|
|
+ * is necessary to specify the order in which the directives are applied. The `priority` is used
|
|
|
+ * to sort the directives before their `compile` functions get called. Priority is defined as a
|
|
|
+ * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
|
|
|
+ * are also run in priority order, but post-link functions are run in reverse order. The order
|
|
|
+ * of directives with the same priority is undefined. The default priority is `0`.
|
|
|
+ *
|
|
|
+ * #### `terminal`
|
|
|
+ * If set to true then the current `priority` will be the last set of directives
|
|
|
+ * which will execute (any directives at the current priority will still execute
|
|
|
+ * as the order of execution on same `priority` is undefined). Note that expressions
|
|
|
+ * and other directives used in the directive's template will also be excluded from execution.
|
|
|
+ *
|
|
|
+ * #### `scope`
|
|
|
+ * The scope property can be `false`, `true`, or an object:
|
|
|
+ *
|
|
|
+ * * **`false` (default):** No scope will be created for the directive. The directive will use its
|
|
|
+ * parent's scope.
|
|
|
+ *
|
|
|
+ * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
|
|
|
+ * the directive's element. If multiple directives on the same element request a new scope,
|
|
|
+ * only one new scope is created.
|
|
|
+ *
|
|
|
+ * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The
|
|
|
+ * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent
|
|
|
+ * scope. This is useful when creating reusable components, which should not accidentally read or modify
|
|
|
+ * data in the parent scope.
|
|
|
+ *
|
|
|
+ * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
|
|
|
+ * directive's element. These local properties are useful for aliasing values for templates. The keys in
|
|
|
+ * the object hash map to the name of the property on the isolate scope; the values define how the property
|
|
|
+ * is bound to the parent scope, via matching attributes on the directive's element:
|
|
|
+ *
|
|
|
+ * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
|
|
|
+ * always a string since DOM attributes are strings. If no `attr` name is specified then the
|
|
|
+ * attribute name is assumed to be the same as the local name. Given `<my-component
|
|
|
+ * my-attr="hello {{name}}">` and the isolate scope definition `scope: { localName:'@myAttr' }`,
|
|
|
+ * the directive's scope property `localName` will reflect the interpolated value of `hello
|
|
|
+ * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
|
|
|
+ * scope. The `name` is read from the parent scope (not the directive's scope).
|
|
|
+ *
|
|
|
+ * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
|
|
|
+ * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
|
|
|
+ * If no `attr` name is specified then the attribute name is assumed to be the same as the local
|
|
|
+ * name. Given `<my-component my-attr="parentModel">` and the isolate scope definition `scope: {
|
|
|
+ * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
|
|
|
+ * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
|
|
|
+ * `localModel` and vice versa. Optional attributes should be marked as such with a question mark:
|
|
|
+ * `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't
|
|
|
+ * optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})
|
|
|
+ * will be thrown upon discovering changes to the local value, since it will be impossible to sync
|
|
|
+ * them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
|
|
|
+ * method is used for tracking changes, and the equality check is based on object identity.
|
|
|
+ * However, if an object literal or an array literal is passed as the binding expression, the
|
|
|
+ * equality check is done by value (using the {@link angular.equals} function). It's also possible
|
|
|
+ * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
|
|
|
+ * `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).
|
|
|
+ *
|
|
|
+ * * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an
|
|
|
+ * expression passed via the attribute `attr`. The expression is evaluated in the context of the
|
|
|
+ * parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the
|
|
|
+ * local name. You can also make the binding optional by adding `?`: `<?` or `<?attr`.
|
|
|
+ *
|
|
|
+ * For example, given `<my-component my-attr="parentModel">` and directive definition of
|
|
|
+ * `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the
|
|
|
+ * value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
|
|
|
+ * in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however
|
|
|
+ * two caveats:
|
|
|
+ * 1. one-way binding does not copy the value from the parent to the isolate scope, it simply
|
|
|
+ * sets the same value. That means if your bound value is an object, changes to its properties
|
|
|
+ * in the isolated scope will be reflected in the parent scope (because both reference the same object).
|
|
|
+ * 2. one-way binding watches changes to the **identity** of the parent value. That means the
|
|
|
+ * {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference
|
|
|
+ * to the value has changed. In most cases, this should not be of concern, but can be important
|
|
|
+ * to know if you one-way bind to an object, and then replace that object in the isolated scope.
|
|
|
+ * If you now change a property of the object in your parent scope, the change will not be
|
|
|
+ * propagated to the isolated scope, because the identity of the object on the parent scope
|
|
|
+ * has not changed. Instead you must assign a new object.
|
|
|
+ *
|
|
|
+ * One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings
|
|
|
+ * back to the parent. However, it does not make this completely impossible.
|
|
|
+ *
|
|
|
+ * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If
|
|
|
+ * no `attr` name is specified then the attribute name is assumed to be the same as the local name.
|
|
|
+ * Given `<my-component my-attr="count = count + value">` and the isolate scope definition `scope: {
|
|
|
+ * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
|
|
|
+ * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
|
|
|
+ * via an expression to the parent scope. This can be done by passing a map of local variable names
|
|
|
+ * and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
|
|
|
+ * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
|
|
|
+ *
|
|
|
+ * In general it's possible to apply more than one directive to one element, but there might be limitations
|
|
|
+ * depending on the type of scope required by the directives. The following points will help explain these limitations.
|
|
|
+ * For simplicity only two directives are taken into account, but it is also applicable for several directives:
|
|
|
+ *
|
|
|
+ * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
|
|
|
+ * * **child scope** + **no scope** => Both directives will share one single child scope
|
|
|
+ * * **child scope** + **child scope** => Both directives will share one single child scope
|
|
|
+ * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use
|
|
|
+ * its parent's scope
|
|
|
+ * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
|
|
|
+ * be applied to the same element.
|
|
|
+ * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives
|
|
|
+ * cannot be applied to the same element.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * #### `bindToController`
|
|
|
+ * This property is used to bind scope properties directly to the controller. It can be either
|
|
|
+ * `true` or an object hash with the same format as the `scope` property.
|
|
|
+ *
|
|
|
+ * When an isolate scope is used for a directive (see above), `bindToController: true` will
|
|
|
+ * allow a component to have its properties bound to the controller, rather than to scope.
|
|
|
+ *
|
|
|
+ * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
|
|
|
+ * properties. You can access these bindings once they have been initialized by providing a controller method called
|
|
|
+ * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
|
|
|
+ * initialized.
|
|
|
+ *
|
|
|
+ * <div class="alert alert-warning">
|
|
|
+ * **Deprecation warning:** although bindings for non-ES6 class controllers are currently
|
|
|
+ * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization
|
|
|
+ * code that relies upon bindings inside a `$onInit` method on the controller, instead.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
|
|
|
+ * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
|
|
|
+ * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
|
|
|
+ * scope (useful for component directives).
|
|
|
+ *
|
|
|
+ * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * #### `controller`
|
|
|
+ * Controller constructor function. The controller is instantiated before the
|
|
|
+ * pre-linking phase and can be accessed by other directives (see
|
|
|
+ * `require` attribute). This allows the directives to communicate with each other and augment
|
|
|
+ * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
|
|
|
+ *
|
|
|
+ * * `$scope` - Current scope associated with the element
|
|
|
+ * * `$element` - Current element
|
|
|
+ * * `$attrs` - Current attributes object for the element
|
|
|
+ * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
|
|
|
+ * `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
|
|
|
+ * * `scope`: (optional) override the scope.
|
|
|
+ * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
|
|
|
+ * * `futureParentElement` (optional):
|
|
|
+ * * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
|
|
|
+ * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
|
|
|
+ * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
|
|
|
+ * and when the `cloneLinkingFn` is passed,
|
|
|
+ * as those elements need to created and cloned in a special way when they are defined outside their
|
|
|
+ * usual containers (e.g. like `<svg>`).
|
|
|
+ * * See also the `directive.templateNamespace` property.
|
|
|
+ * * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
|
|
|
+ * then the default transclusion is provided.
|
|
|
+ * The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
|
|
|
+ * `true` if the specified slot contains content (i.e. one or more DOM nodes).
|
|
|
+ *
|
|
|
+ * #### `require`
|
|
|
+ * Require another directive and inject its controller as the fourth argument to the linking function. The
|
|
|
+ * `require` property can be a string, an array or an object:
|
|
|
+ * * a **string** containing the name of the directive to pass to the linking function
|
|
|
+ * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
|
|
|
+ * linking function will be an array of controllers in the same order as the names in the `require` property
|
|
|
+ * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
|
|
|
+ * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
|
|
|
+ * controllers.
|
|
|
+ *
|
|
|
+ * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
|
|
|
+ * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
|
|
|
+ * have been constructed but before `$onInit` is called.
|
|
|
+ * If the name of the required controller is the same as the local name (the key), the name can be
|
|
|
+ * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
|
|
|
+ * See the {@link $compileProvider#component} helper for an example of how this can be used.
|
|
|
+ * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
|
|
|
+ * raised (unless no link function is specified and the required controllers are not being bound to the directive
|
|
|
+ * controller, in which case error checking is skipped). The name can be prefixed with:
|
|
|
+ *
|
|
|
+ * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
|
|
|
+ * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
|
|
|
+ * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
|
|
|
+ * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
|
|
|
+ * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
|
|
|
+ * `null` to the `link` fn if not found.
|
|
|
+ * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
|
|
|
+ * `null` to the `link` fn if not found.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * #### `controllerAs`
|
|
|
+ * Identifier name for a reference to the controller in the directive's scope.
|
|
|
+ * This allows the controller to be referenced from the directive template. This is especially
|
|
|
+ * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
|
|
|
+ * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
|
|
|
+ * `controllerAs` reference might overwrite a property that already exists on the parent scope.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * #### `restrict`
|
|
|
+ * String of subset of `EACM` which restricts the directive to a specific directive
|
|
|
+ * declaration style. If omitted, the defaults (elements and attributes) are used.
|
|
|
+ *
|
|
|
+ * * `E` - Element name (default): `<my-directive></my-directive>`
|
|
|
+ * * `A` - Attribute (default): `<div my-directive="exp"></div>`
|
|
|
+ * * `C` - Class: `<div class="my-directive: exp;"></div>`
|
|
|
+ * * `M` - Comment: `<!-- directive: my-directive exp -->`
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * #### `templateNamespace`
|
|
|
+ * String representing the document type used by the markup in the template.
|
|
|
+ * AngularJS needs this information as those elements need to be created and cloned
|
|
|
+ * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
|
|
|
+ *
|
|
|
+ * * `html` - All root nodes in the template are HTML. Root nodes may also be
|
|
|
+ * top-level elements such as `<svg>` or `<math>`.
|
|
|
+ * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
|
|
|
+ * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
|
|
|
+ *
|
|
|
+ * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
|
|
|
+ *
|
|
|
+ * #### `template`
|
|
|
+ * HTML markup that may:
|
|
|
+ * * Replace the contents of the directive's element (default).
|
|
|
+ * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
|
|
|
+ * * Wrap the contents of the directive's element (if `transclude` is true).
|
|
|
+ *
|
|
|
+ * Value may be:
|
|
|
+ *
|
|
|
+ * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
|
|
|
+ * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
|
|
|
+ * function api below) and returns a string value.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * #### `templateUrl`
|
|
|
+ * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
|
|
|
+ *
|
|
|
+ * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
|
|
|
+ * for later when the template has been resolved. In the meantime it will continue to compile and link
|
|
|
+ * sibling and parent elements as though this element had not contained any directives.
|
|
|
+ *
|
|
|
+ * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
|
|
|
+ * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
|
|
|
+ * case when only one deeply nested directive has `templateUrl`.
|
|
|
+ *
|
|
|
+ * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
|
|
|
+ *
|
|
|
+ * You can specify `templateUrl` as a string representing the URL or as a function which takes two
|
|
|
+ * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
|
|
|
+ * a string value representing the url. In either case, the template URL is passed through {@link
|
|
|
+ * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
|
|
|
+ * specify what the template should replace. Defaults to `false`.
|
|
|
+ *
|
|
|
+ * * `true` - the template will replace the directive's element.
|
|
|
+ * * `false` - the template will replace the contents of the directive's element.
|
|
|
+ *
|
|
|
+ * The replacement process migrates all of the attributes / classes from the old element to the new
|
|
|
+ * one. See the {@link guide/directive#template-expanding-directive
|
|
|
+ * Directives Guide} for an example.
|
|
|
+ *
|
|
|
+ * There are very few scenarios where element replacement is required for the application function,
|
|
|
+ * the main one being reusable custom components that are used within SVG contexts
|
|
|
+ * (because SVG doesn't work with custom elements in the DOM tree).
|
|
|
+ *
|
|
|
+ * #### `transclude`
|
|
|
+ * Extract the contents of the element where the directive appears and make it available to the directive.
|
|
|
+ * The contents are compiled and provided to the directive as a **transclusion function**. See the
|
|
|
+ * {@link $compile#transclusion Transclusion} section below.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * #### `compile`
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * function compile(tElement, tAttrs, transclude) { ... }
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * The compile function deals with transforming the template DOM. Since most directives do not do
|
|
|
+ * template transformation, it is not used often. The compile function takes the following arguments:
|
|
|
+ *
|
|
|
+ * * `tElement` - template element - The element where the directive has been declared. It is
|
|
|
+ * safe to do template transformation on the element and child elements only.
|
|
|
+ *
|
|
|
+ * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
|
|
|
+ * between all directive compile functions.
|
|
|
+ *
|
|
|
+ * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
|
|
|
+ *
|
|
|
+ * <div class="alert alert-warning">
|
|
|
+ * **Note:** The template instance and the link instance may be different objects if the template has
|
|
|
+ * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
|
|
|
+ * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
|
|
|
+ * should be done in a linking function rather than in a compile function.

|
+ * stack overflow errors.
|
|
|
+ *
|
|
|
+ * This can be avoided by manually using $compile in the postLink function to imperatively compile

|
|

|
|
|

|
|
+ *
|
|
|
+ * #### `link`
|
|
|
+ * This property is used only if the `compile` property is not defined.
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
|
|
|
+ * executed after the template has been cloned. This is where most of the directive logic will be
|
|
|
+ * put.
|
|
|
+ *
|
|
|
+ * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
|
|
|
+ * directive for registering {@link ng.$rootScope.Scope#$watch watches}.
|
|
|
+ *
|
|
|
+ * * `iElement` - instance element - The element where the directive is to be used. It is safe to
|
|
|
+ * manipulate the children of the element only in `postLink` function since the children have
|
|
|
+ * already been linked.
|
|
|
+ *
|
|
|
+ * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
|
|
|
+ * between all directive linking functions.
|
|
|
+ *
|
|
|
+ * * `controller` - the directive's required controller instance(s) - Instances are shared
|
|
|
+ * among all directives, which allows the directives to use the controllers as a communication
|
|
|
+ * channel. The exact value depends on the directive's `require` property:
|
|
|
+ * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
|
|
|
+ * * `string`: the controller instance
|
|
|
+ * * `array`: array of controller instances
|
|
|
+ *
|
|
|
+ * If a required controller cannot be found, and it is optional, the instance is `null`,
|
|
|
+ * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
|
|
|
+ *
|
|
|
+ * Note that you can also require the directive's own controller - it will be made available like
|
|
|
+ * any other controller.
|
|
|
+ *
|
|
|
+ * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
|
|
|
+ * This is the same as the `$transclude` parameter of directive controllers,
|
|
|
+ * see {@link ng.$compile#-controller- the controller section for details}.
|
|
|
+ * `function([scope], cloneLinkingFn, futureParentElement)`.
|
|
|
+ *
|
|
|
+ * #### Pre-linking function
|
|
|
+ *
|
|
|
+ * Executed before the child elements are linked. Not safe to do DOM transformation since the
|
|
|
+ * compiler linking function will fail to locate the correct elements for linking.
|
|
|
+ *
|
|
|
+ * #### Post-linking function
|
|
|
+ *
|
|
|
+ * Executed after the child elements are linked.
|
|
|
+ *
|
|
|
+ * Note that child elements that contain `templateUrl` directives will not have been compiled
|
|
|
+ * and linked since they are waiting for their template to load asynchronously and their own
|
|
|
+ * compilation and linking has been suspended until that occurs.
|
|
|
+ *
|
|
|
+ * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
|
|
|
+ * for their async templates to be resolved.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ### Transclusion
|
|
|
+ *
|
|
|
+ * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
|
|
|
+ * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
|
|
|
+ * scope from where they were taken.
|
|
|
+ *
|
|
|
+ * Transclusion is used (often with {@link ngTransclude}) to insert the
|
|
|
+ * original contents of a directive's element into a specified place in the template of the directive.
|
|
|
+ * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
|
|
|
+ * content has access to the properties on the scope from which it was taken, even if the directive
|
|
|
+ * has isolated scope.
|
|
|
+ * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
|
|
|
+ *
|
|
|
+ * This makes it possible for the widget to have private state for its template, while the transcluded
|
|
|
+ * content has access to its originating scope.
|
|
|
+ *
|
|
|
+ * <div class="alert alert-warning">
|
|
|
+ * **Note:** When testing an element transclude directive you must not place the directive at the root of the
|
|
|
+ * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
|
|
|
+ * Testing Transclusion Directives}.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
|
|
|
+ * directive's element, the entire element or multiple parts of the element contents:
|
|
|
+ *
|
|
|
+ * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
|
|
|
+ * * `'element'` - transclude the whole of the directive's element including any directives on this
|
|
|
+ * element that defined at a lower priority than this directive. When used, the `template`
|
|
|
+ * property is ignored.
|
|
|
+ * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
|
|
|
+ *
|
|
|
+ * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
|
|
|
+ *
|
|
|
+ * This object is a map where the keys are the name of the slot to fill and the value is an element selector
|
|
|
+ * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
|
|
|
+ * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
|
|
|
+ *
|
|
|
+ * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
|
|
|
+ *
|
|
|
+ * If the element selector is prefixed with a `?` then that slot is optional.
|
|
|
+ *
|
|
|
+ * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to
|
|
|
+ * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
|
|
|
+ *
|
|
|
+ * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
|
|
|
+ * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
|
|
|
+ * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
|
|
|
+ * injectable into the directive's controller.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * #### Transclusion Functions
|
|
|
+ *
|
|
|
+ * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
|
|
|
+ * function** to the directive's `link` function and `controller`. This transclusion function is a special
|
|
|
+ * **linking function** that will return the compiled contents linked to a new transclusion scope.
|
|
|
+ *
|
|
|
+ * <div class="alert alert-info">
|
|
|
+ * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
|
|
|
+ * ngTransclude will deal with it for us.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * If you want to manually control the insertion and removal of the transcluded content in your directive
|
|
|
+ * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
|
|
|
+ * object that contains the compiled DOM, which is linked to the correct transclusion scope.
|
|
|
+ *
|
|
|
+ * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
|
|
|
+ * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
|
|
|
+ * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.
|
|
|
+ *
|
|
|
+ * <div class="alert alert-info">
|
|
|
+ * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
|
|
|
+ * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
|
|
|
+ * attach function**:
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * var transcludedContent, transclusionScope;
|
|
|
+ *
|
|
|
+ * $transclude(function(clone, scope) {
|
|
|
+ * element.append(clone);
|
|
|
+ * transcludedContent = clone;
|
|
|
+ * transclusionScope = scope;
|
|
|
+ * });
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
|
|
|
+ * associated transclusion scope:
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * transcludedContent.remove();
|
|
|
+ * transclusionScope.$destroy();
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * <div class="alert alert-info">
|
|
|
+ * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
|
|
|
+ * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
|
|
|
+ * then you are also responsible for calling `$destroy` on the transclusion scope.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
|
|
|
+ * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
|
|
|
+ * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * #### Transclusion Scopes
|
|
|
+ *
|
|
|
+ * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
|
|
|
+ * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
|
|
|
+ * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
|
|
|
+ * was taken.
|
|
|
+ *
|
|
|
+ * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
|
|
|
+ * like this:
|
|
|
+ *
|
|
|
+ * ```html
|
|
|
+ * <div ng-app>
|
|
|
+ * <div isolate>
|
|
|
+ * <div transclusion>
|
|
|
+ * </div>
|
|
|
+ * </div>
|
|
|
+ * </div>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * The `$parent` scope hierarchy will look like this:
|
|
|
+ *
|
|
|
+ ```
|
|
|
+ - $rootScope
|
|
|
+ - isolate
|
|
|
+ - transclusion
|
|
|
+ ```
|
|
|
+ *
|
|
|
+ * but the scopes will inherit prototypically from different scopes to their `$parent`.
|
|
|
+ *
|
|
|
+ ```
|
|
|
+ - $rootScope
|
|
|
+ - transclusion
|
|
|
+ - isolate
|
|
|
+ ```
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ### Attributes
|
|
|
+ *
|
|
|
+ * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
|
|
|
+ * `link()` or `compile()` functions. It has a variety of uses.
|
|
|
+ *
|
|
|
+ * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
|
|
|
+ * 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
|
|
|
+ * to the attributes.
|
|
|
+ *
|
|
|
+ * * *Directive inter-communication:* All directives share the same instance of the attributes
|
|
|
+ * object which allows the directives to use the attributes object as inter directive
|
|
|
+ * communication.
|
|
|
+ *
|
|
|
+ * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
|
|
|
+ * allowing other directives to read the interpolated value.
|
|
|
+ *
|
|
|
+ * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
|
|
|
+ * that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
|
|
|
+ * the only way to easily get the actual value because during the linking phase the interpolation
|
|
|
+ * hasn't been evaluated yet and so the value is at this time set to `undefined`.
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * function linkingFn(scope, elm, attrs, ctrl) {
|
|
|
+ * // get the attribute value
|
|
|
+ * console.log(attrs.ngModel);
|
|
|
+ *
|
|
|
+ * // change the attribute
|
|
|
+ * attrs.$set('ngModel', 'new value');
|
|
|
+ *
|
|
|
+ * // observe changes to interpolated attribute
|
|
|
+ * attrs.$observe('ngModel', function(value) {
|
|
|
+ * console.log('ngModel has changed value to ' + value);
|
|
|
+ * });
|
|
|
+ * }
|
|
|
+ * ```
|
|
|
+ *

|
|
+ * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
|
|
|
+ * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
|
|
|
+ * `template` and call the `cloneAttachFn` function allowing the caller to attach the
|
|
|
+ * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
|
|
|
+ * called as: <br/> `cloneAttachFn(clonedElement, scope)` where:
|
|
|
+ *
|
|
|
+ * * `clonedElement` - is a clone of the original `element` passed into the compiler.
|
|
|
+ * * `scope` - is the current scope with which the linking function is working with.
|
|
|
+ *
|
|
|
+ * * `options` - An optional object hash with linking options. If `options` is provided, then the following
|
|
|
+ * keys may be used to control linking behavior:
|
|
|
+ *
|
|
|
+ * * `parentBoundTranscludeFn` - the transclude function made available to
|
|
|
+ * directives; if given, it will be passed through to the link functions of
|
|
|
+ * directives found in `element` during compilation.
|
|
|
+ * * `transcludeControllers` - an object hash with keys that map controller names
|
|
|
+ * to a hash with the key `instance`, which maps to the controller instance;
|
|
|
+ * if given, it will make the controllers available to directives on the compileNode:
|
|
|
+ * ```
|
|
|
+ * {
|
|
|
+ * parent: {
|
|
|
+ * instance: parentControllerInstance
|
|
|
+ * }
|
|
|
+ * }
|
|
|
+ * ```
|
|
|
+ * * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
|
|
|
+ * the cloned elements; only needed for transcludes that are allowed to contain non html
|
|
|
+ * elements (e.g. SVG elements). See also the directive.controller property.
|
|
|
+ *
|
|
|
+ * Calling the linking function returns the element of the template. It is either the original
|
|
|
+ * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
|
|
|
+ *
|
|
|
+ * After linking the view is not updated until after a call to $digest which typically is done by
|
|
|
+ * Angular automatically.
|
|
|
+ *
|
|
|
+ * If you need access to the bound view, there are two ways to do it:
|
|
|
+ *
|
|
|
+ * - If you are not asking the linking function to clone the template, create the DOM element(s)
|
|
|
+ * before you send them to the compiler and keep this reference around.
|
|
|
+ * ```js
|
|
|
+ * var element = $compile('<p>{{total}}</p>')(scope);
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * - if on the other hand, you need the element to be cloned, the view reference from the original
|
|
|
+ * example would not point to the clone, but rather to the original template that was cloned. In
|
|
|
+ * this case, you can access the clone via the cloneAttachFn:
|
|
|
+ * ```js
|
|
|
+ * var templateElement = angular.element('<p>{{total}}</p>'),
|
|
|
+ * scope = ....;
|
|
|
+ *
|
|
|
+ * var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
|
|
|
+ * //attach the clone to DOM document at the right place
|
|
|
+ * });
|
|
|
+ *
|
|
|
+ * //now we have reference to the cloned DOM via `clonedElement`
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ *
|
|

+ * For information on how the compiler works, see the
|
|

|
|
|
+ * Register a **component definition** with the compiler. This is a shorthand for registering a special
|
|
|
+ * type of directive, which represents a self-contained UI component in your application. Such components
|
|
|
+ * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
|
|
|
+ *
|
|
|
+ * Component definitions are very simple and do not require as much configuration as defining general
|
|
|
+ * directives. Component definitions usually consist only of a template and a controller backing it.
|
|
|
+ *
|
|
|
+ * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
|
|
|
+ * `bindToController`. They always have **isolate scope** and are restricted to elements.
|
|
|
+ *
|
|
|
+ * Here are a few examples of how you would usually define components:
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * var myMod = angular.module(...);
|
|
|
+ * myMod.component('myComp', {
|
|
|
+ * template: '<div>My name is {{$ctrl.name}}</div>',
|
|
|
+ * controller: function() {
|
|
|
+ * this.name = 'shahar';
|
|
|
+ * }
|
|
|
+ * });
|
|
|
+ *
|
|
|
+ * myMod.component('myComp', {
|
|
|
+ * template: '<div>My name is {{$ctrl.name}}</div>',
|
|
|
+ * bindings: {name: '@'}
|
|
|
+ * });
|
|
|
+ *
|
|
|
+ * myMod.component('myComp', {
|
|
|
+ * templateUrl: 'views/my-comp.html',
|
|
|
+ * controller: 'MyCtrl',
|
|
|
+ * controllerAs: 'ctrl',
|
|
|
+ * bindings: {name: '@'}
|
|
|
+ * });
|
|
|
+ *
|
|
|
+ * ```
|
|
|
+ * For more examples, and an in-depth guide, see the {@link guide/component component guide}.
|
|
|
+ *

|
|
|
+ * Any uncaught exception in angular expressions is delegated to this service.
|
|
|
+ * The default implementation simply delegates to `$log.error` which logs it into
|
|
|
+ * the browser console.
|
|
|
+ *
|
|
|
+ * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
|
|
|
+ * {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.
|
|
|
+ *
|
|
|
+ * ## Example:
|
|
|
+ *
|
|
|
+ * The example below will overwrite the default `$exceptionHandler` in order to (a) log uncaught
|
|
|
+ * errors to the backend for later inspection by the developers and (b) to use `$log.warn()` instead
|
|
|
+ * of `$log.error()`.
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * angular.
|
|
|
+ * module('exceptionOverwrite', []).
|
|
|
+ * factory('$exceptionHandler', ['$log', 'logErrorsToBackend', function($log, logErrorsToBackend) {
|
|
|
+ * return function myExceptionHandler(exception, cause) {
|
|
|
+ * logErrorsToBackend(exception, cause);
|
|

+ * $log.warn(exception, cause);

|
|
|
+ * methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
|
|
|
+ * (unless executed during a digest).
|
|
|
+ *
|
|
|
+ * If you wish, you can manually delegate exceptions, e.g.

+ * {@link $httpProvider#defaults `$httpProvider`}.
|
|

+ *
|
|
|
+ * Additionally, you can inject the serializer and use it explicitly, for example to serialize

|
|
|
+ * The `$http` service is a core Angular service that facilitates communication with the remote
|
|
|
+ * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
|
|
|
+ * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
|
|
|
+ *
|
|
|
+ * For unit testing applications that use `$http` service, see
|
|
|
+ * {@link ngMock.$httpBackend $httpBackend mock}.
|
|
|
+ *
|
|
|
+ * For a higher level of abstraction, please check out the {@link ngResource.$resource
|
|
|
+ * $resource} service.
|
|
|
+ *
|
|
|
+ * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
|
|
|
+ * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
|
|
|
+ * it is important to familiarize yourself with these APIs and the guarantees they provide.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ## General usage
|
|
|
+ * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
|
|
|
+ * that is used to generate an HTTP request and returns a {@link ng.$q promise}.
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * // Simple GET request example:
|
|
|
+ * $http({
|
|
|
+ * method: 'GET',
|
|
|
+ * url: '/someUrl'
|
|
|
+ * }).then(function successCallback(response) {
|
|
|
+ * // this callback will be called asynchronously
|
|
|
+ * // when the response is available
|
|
|
+ * }, function errorCallback(response) {
|
|
|
+ * // called asynchronously if an error occurs
|
|
|
+ * // or server returns response with an error status.
|
|
|
+ * });
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * The response object has these properties:
|
|
|
+ *
|
|
|
+ * - **data** – `{string|Object}` – The response body transformed with the transform
|
|
|
+ * functions.
|
|
|
+ * - **status** – `{number}` – HTTP status code of the response.
|
|
|
+ * - **headers** – `{function([headerName])}` – Header getter function.
|
|
|
+ * - **config** – `{Object}` – The configuration object that was used to generate the request.
|
|
|
+ * - **statusText** – `{string}` – HTTP status text of the response.
|
|
|
+ *
|
|
|
+ * A response status code between 200 and 299 is considered a success status and will result in
|
|
|
+ * the success callback being called. Any response status code outside of that range is
|
|
|
+ * considered an error status and will result in the error callback being called.
|
|
|
+ * Also, status codes less than -1 are normalized to zero. -1 usually means the request was
|
|
|
+ * aborted, e.g. using a `config.timeout`.
|
|
|
+ * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning
|
|
|
+ * that the outcome (success or error) will be determined by the final response status code.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ## Shortcut methods
|
|
|
+ *
|
|
|
+ * Shortcut methods are also available. All shortcut methods require passing in the URL, and
|
|
|
+ * request data must be passed in for POST/PUT requests. An optional config can be passed as the
|
|
|
+ * last argument.
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * $http.get('/someUrl', config).then(successCallback, errorCallback);
|
|
|
+ * $http.post('/someUrl', data, config).then(successCallback, errorCallback);
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * Complete list of shortcut methods:
|
|
|
+ *
|
|
|
+ * - {@link ng.$http#get $http.get}
|
|
|
+ * - {@link ng.$http#head $http.head}
|
|
|
+ * - {@link ng.$http#post $http.post}
|
|
|
+ * - {@link ng.$http#put $http.put}
|
|
|
+ * - {@link ng.$http#delete $http.delete}
|
|
|
+ * - {@link ng.$http#jsonp $http.jsonp}
|
|
|
+ * - {@link ng.$http#patch $http.patch}
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ## Writing Unit Tests that use $http
|
|
|
+ * When unit testing (using {@link ngMock ngMock}), it is necessary to call
|
|
|
+ * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
|
|
|
+ * request using trained responses.
|
|
|
+ *
|
|
|
+ * ```
|
|
|
+ * $httpBackend.expectGET(...);
|
|
|
+ * $http.get(...);
|
|
|
+ * $httpBackend.flush();
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * ## Setting HTTP Headers
|
|
|
+ *
|
|
|
+ * The $http service will automatically add certain HTTP headers to all requests. These defaults
|
|
|
+ * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
|
|
|
+ * object, which currently contains this default configuration:
|
|
|
+ *
|
|
|
+ * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
|
|
|
+ * - <code>Accept: application/json, text/plain, \*/\*</code>
|
|
|
+ * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
|
|
|
+ * - `Content-Type: application/json`
|
|
|
+ * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
|
|
|
+ * - `Content-Type: application/json`
|
|
|
+ *
|
|
|
+ * To add or overwrite these defaults, simply add or remove a property from these configuration
|
|
|
+ * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
|
|
|
+ * with the lowercased HTTP method name as the key, e.g.
|
|
|
+ * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
|
|
|
+ *
|
|
|
+ * The defaults can also be set at runtime via the `$http.defaults` object in the same
|
|
|
+ * fashion. For example:
|
|
|
+ *
|
|
|
+ * ```
|
|
|
+ * module.run(function($http) {
|
|
|
+ * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
|
|
|
+ * });
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * In addition, you can supply a `headers` property in the config object passed when
|
|
|
+ * calling `$http(config)`, which overrides the defaults without changing them globally.
|
|
|
+ *
|
|
|
+ * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
|
|
|
+ * Use the `headers` property, setting the desired header to `undefined`. For example:
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * var req = {
|
|
|
+ * method: 'POST',
|
|
|
+ * url: 'http://example.com',
|
|
|
+ * headers: {
|
|
|
+ * 'Content-Type': undefined
|
|
|
+ * },
|
|
|
+ * data: { test: 'test' }
|
|
|
+ * }
|
|
|
+ *
|
|
|
+ * $http(req).then(function(){...}, function(){...});
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * ## Transforming Requests and Responses
|
|
|
+ *
|
|
|
+ * Both requests and responses can be transformed using transformation functions: `transformRequest`
|
|
|
+ * and `transformResponse`. These properties can be a single function that returns
|
|
|
+ * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
|
|
|
+ * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
|
|
|
+ *
|
|
|
+ * <div class="alert alert-warning">
|
|
|
+ * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
|
|
|
+ * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
|
|
|
+ * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
|
|
|
+ * function will be reflected on the scope and in any templates where the object is data-bound.
|
|
|
+ * To prevent this, transform functions should have no side-effects.
|
|
|
+ * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * ### Default Transformations
|
|
|
+ *
|
|
|
+ * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
|
|
|
+ * `defaults.transformResponse` properties. If a request does not provide its own transformations
|
|
|
+ * then these will be applied.
|
|
|
+ *
|
|
|
+ * You can augment or replace the default transformations by modifying these properties by adding to or
|
|
|
+ * replacing the array.
|
|
|
+ *
|
|
|
+ * Angular provides the following default transformations:
|
|
|
+ *
|
|
|
+ * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
|
|
|
+ *
|
|
|
+ * - If the `data` property of the request configuration object contains an object, serialize it
|
|
|
+ * into JSON format.
|
|
|
+ *
|
|
|
+ * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
|
|
|
+ *
|
|
|
+ * - If XSRF prefix is detected, strip it (see Security Considerations section below).
|
|
|
+ * - If JSON response is detected, deserialize it using a JSON parser.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ### Overriding the Default Transformations Per Request
|
|
|
+ *
|
|
|
+ * If you wish to override the request/response transformations only for a single request then provide
|
|
|
+ * `transformRequest` and/or `transformResponse` properties on the configuration object passed
|
|
|
+ * into `$http`.
|
|
|
+ *
|
|
|
+ * Note that if you provide these properties on the config object the default transformations will be
|
|
|
+ * overwritten. If you wish to augment the default transformations then you must include them in your
|
|
|
+ * local transformation array.
|
|
|
+ *
|
|
|
+ * The following code demonstrates adding a new response transformation to be run after the default response
|
|
|
+ * transformations have been run.
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * function appendTransform(defaults, transform) {
|
|
|
+ *
|
|
|
+ * // We can't guarantee that the default transformation is an array
|
|
|
+ * defaults = angular.isArray(defaults) ? defaults : [defaults];
|
|
|
+ *
|
|
|
+ * // Append the new transformation to the defaults
|
|
|
+ * return defaults.concat(transform);
|
|
|
+ * }
|
|
|
+ *
|
|
|
+ * $http({
|
|
|
+ * url: '...',
|
|
|
+ * method: 'GET',
|
|
|
+ * transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
|
|
|
+ * return doTransform(value);
|
|
|
+ * })
|
|
|
+ * });
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ## Caching
|
|
|
+ *
|
|
|
+ * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
|
|
|
+ * set the config.cache value or the default cache value to TRUE or to a cache object (created
|
|
|
+ * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
|
|
|
+ * precedence over the default cache value.
|
|
|
+ *
|
|
|
+ * In order to:
|
|
|
+ * * cache all responses - set the default cache value to TRUE or to a cache object
|
|
|
+ * * cache a specific response - set config.cache value to TRUE or to a cache object
|
|
|
+ *
|
|
|
+ * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
|
|
|
+ * then the default `$cacheFactory("$http")` object is used.
|
|
|
+ *
|
|
|
+ * The default cache value can be set by updating the
|
|
|
+ * {@link ng.$http#defaults `$http.defaults.cache`} property or the
|
|
|
+ * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
|
|
|
+ *
|
|
|
+ * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
|
|
|
+ * the relevant cache object. The next time the same request is made, the response is returned
|
|
|
+ * from the cache without sending a request to the server.
|
|
|
+ *
|
|
|
+ * Take note that:
|
|
|
+ *
|
|
|
+ * * Only GET and JSONP requests are cached.
|
|
|
+ * * The cache key is the request URL including search parameters; headers are not considered.
|
|
|
+ * * Cached responses are returned asynchronously, in the same way as responses from the server.
|
|
|
+ * * If multiple identical requests are made using the same cache, which is not yet populated,
|
|
|
+ * one request will be made to the server and remaining requests will return the same response.
|
|
|
+ * * A cache-control header on the response does not affect if or how responses are cached.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ## Interceptors
|
|
|
+ *
|
|
|
+ * Before you start creating interceptors, be sure to understand the
|
|
|
+ * {@link ng.$q $q and deferred/promise APIs}.
|
|
|
+ *
|
|
|
+ * For purposes of global error handling, authentication, or any kind of synchronous or
|
|
|
+ * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
|
|
|
+ * able to intercept requests before they are handed to the server and
|
|
|
+ * responses before they are handed over to the application code that
|
|
|
+ * initiated these requests. The interceptors leverage the {@link ng.$q
|
|
|
+ * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
|
|
|
+ *
|
|
|
+ * The interceptors are service factories that are registered with the `$httpProvider` by
|
|
|
+ * adding them to the `$httpProvider.interceptors` array. The factory is called and
|
|
|
+ * injected with dependencies (if specified) and returns the interceptor.
|
|
|
+ *
|
|
|
+ * There are two kinds of interceptors (and two kinds of rejection interceptors):
|
|
|
+ *
|
|
|
+ * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
|
|
|
+ * modify the `config` object or create a new one. The function needs to return the `config`
|
|
|
+ * object directly, or a promise containing the `config` or a new `config` object.
|
|
|
+ * * `requestError`: interceptor gets called when a previous interceptor threw an error or
|
|
|
+ * resolved with a rejection.
|
|
|
+ * * `response`: interceptors get called with http `response` object. The function is free to
|
|
|
+ * modify the `response` object or create a new one. The function needs to return the `response`
|
|
|
+ * object directly, or as a promise containing the `response` or a new `response` object.
|
|
|
+ * * `responseError`: interceptor gets called when a previous interceptor threw an error or
|
|
|
+ * resolved with a rejection.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * // register the interceptor as a service
|
|
|
+ * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
|
|
|
+ * return {
|
|
|
+ * // optional method
|
|
|
+ * 'request': function(config) {
|
|
|
+ * // do something on success
|
|
|
+ * return config;
|
|
|
+ * },
|
|
|
+ *
|
|
|
+ * // optional method
|
|
|
+ * 'requestError': function(rejection) {
|
|
|
+ * // do something on error
|
|
|
+ * if (canRecover(rejection)) {
|
|
|
+ * return responseOrNewPromise
|
|
|
+ * }
|
|
|
+ * return $q.reject(rejection);
|
|
|
+ * },
|
|
|
+ *
|

|

|
|

|
|
|

|
|
|
+ * };
|
|
|
+ * });
|
|
|
+ *
|
|
|

|
|
|
+ *
|
|
|
+ *
|
|

|
|
|
+ * ## Security Considerations
|
|
|
+ *
|
|
|
+ * When designing web applications, consider security threats from:
|
|
|
+ *
|
|
|
+ * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
|
|
|
+ * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
|
|
|
+ *
|
|
|
+ * Both server and the client must cooperate in order to eliminate these threats. Angular comes
|
|
|
+ * pre-configured with strategies that address these issues, but for this to work backend server
|
|
|
+ * cooperation is required.
|
|
|
+ *
|
|
|
+ * ### JSON Vulnerability Protection
|
|
|
+ *
|
|
|
+ * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
|
|
|
+ * allows third party website to turn your JSON resource URL into
|
|
|
+ * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
|
|
|
+ * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
|
|
|
+ * Angular will automatically strip the prefix before processing it as JSON.
|
|
|
+ *
|
|
|
+ * For example if your server needs to return:
|
|
|
+ * ```js
|
|
|
+ * ['one','two']
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * which is vulnerable to attack, your server can return:
|
|
|
+ * ```js
|
|
|
+ * )]}',
|
|
|
+ * ['one','two']
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * Angular will strip the prefix, before processing the JSON.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ### Cross Site Request Forgery (XSRF) Protection
|
|
|
+ *
|
|
|
+ * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
|
|
|
+ * which the attacker can trick an authenticated user into unknowingly executing actions on your
|
|
|
+ * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the
|
|
|
+ * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
|
|
|
+ * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the
|
|
|
+ * cookie, your server can be assured that the XHR came from JavaScript running on your domain.
|
|
|
+ * The header will not be set for cross-domain requests.
|
|
|
+ *
|
|
|
+ * To take advantage of this, your server needs to set a token in a JavaScript readable session
|
|
|
+ * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
|
|
|
+ * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
|
|
|
+ * that only JavaScript running on your domain could have sent the request. The token must be
|
|
|
+ * unique for each user and must be verifiable by the server (to prevent the JavaScript from
|
|
|
+ * making up its own tokens). We recommend that the token is a digest of your site's
|
|
|
+ * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
|
|
|
+ * for added security.
|
|
|
+ *
|
|
|
+ * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
|
|
|
+ * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
|
|
|
+ * or the per-request config object.
|
|
|
+ *
|
|
|
+ * In order to prevent collisions in environments where multiple Angular apps share the
|
|
|
+ * same domain or subdomain, we recommend that each application uses unique cookie name.
|
|
|
+ *
|
|
|
+ * @param {object} config Object describing the request to be made and how it should be
|
|
|
+ * processed. The object has following properties:
|
|
|
+ *
|
|
|
+ * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
|
|
|
+ * - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested;
|
|
|
+ * or an object created by a call to `$sce.trustAsResourceUrl(url)`.
|
|
|
+ * - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized
|
|
|
+ * with the `paramSerializer` and appended as GET parameters.
|
|
|
+ * - **data** – `{string|Object}` – Data to be sent as the request message data.
|
|
|
+ * - **headers** – `{Object}` – Map of strings or functions which return strings representing
|
|
|
+ * HTTP headers to send to the server. If the return value of a function is null, the
|
|
|
+ * header will not be sent. Functions accept a config object as an argument.
|
|
|
+ * - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
|
|
|
+ * To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
|
|
|
+ * The handler will be called in the context of a `$apply` block.
|
|
|
+ * - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
|
|
|
+ * object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
|
|
|
+ * The handler will be called in the context of a `$apply` block.
|
|
|
+ * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
|
|
|
+ * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
|
|
|
+ * - **transformRequest** –
|
|
|
+ * `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
|
|
|
+ * transform function or an array of such functions. The transform function takes the http
|
|
|
+ * request body and headers and returns its transformed (typically serialized) version.
|
|
|
+ * See {@link ng.$http#overriding-the-default-transformations-per-request
|
|
|
+ * Overriding the Default Transformations}
|
|
|
+ * - **transformResponse** –
|
|
|
+ * `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
|
|
|
+ * transform function or an array of such functions. The transform function takes the http
|
|
|
+ * response body, headers and status and returns its transformed (typically deserialized) version.
|
|
|
+ * See {@link ng.$http#overriding-the-default-transformations-per-request
|
|
|
+ * Overriding the Default Transformations}
|
|
|
+ * - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to
|
|
|
+ * prepare the string representation of request parameters (specified as an object).
|
|
|
+ * If specified as string, it is interpreted as function registered with the
|
|
|
+ * {@link $injector $injector}, which means you can create your own serializer
|
|
|
+ * by registering it as a {@link auto.$provide#service service}.
|
|
|
+ * The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
|
|
|
+ * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
|
|
|
+ * - **cache** – `{boolean|Object}` – A boolean value or object created with
|
|
|
+ * {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
|
|
|
+ * See {@link $http#caching $http Caching} for more information.
|
|
|
+ * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
|
|
|
+ * that should abort the request when resolved.
|
|
|
+ * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
|
|
|
+ * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
|
|
|
+ * for more information.
|
|
|
+ * - **responseType** - `{string}` - see
|
|
|
+ * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
|
|
|
+ *
|
|
|
+ * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
|
|
|
+ * when the request succeeds or fails.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
|
|
|
+ * requests. This is primarily meant to be used for debugging purposes.

|
|
|

|
|
|
+ * setting the `jsonpCallbackParam` property on the request config object.
|

|

|

|

|
|

|

+ * var exp = $interpolate('Hello {{name | uppercase}}!');

+ * expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');
|

|
+ * ```
|
|
|
+ *
|
|
|
+ * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
|
|
|
+ * `true`, the interpolation function will return `undefined` unless all embedded expressions
|
|

+ * evaluate to a value other than `undefined`.
|
|
|
+ *
|
|
|
+ * ```js
|

|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
|
|
|
+ *
|
|
|
+ * #### Escaped Interpolation
|
|
|
+ * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
|
|
|
+ * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
|
|
|
+ * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
|
|
|
+ * or binding.
|
|
|
+ *
|
|
|
+ * This enables web-servers to prevent script injection attacks and defacing attacks, to some
|
|
|
+ * degree, while also enabling code examples to work without relying on the
|
|
|
+ * {@link ng.directive:ngNonBindable ngNonBindable} directive.
|
|
|
+ *
|
|
|
+ * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
|
|
|
+ * replacing angle brackets (<, >) with &lt; and &gt; respectively, and replacing all
|
|
|
+ * interpolation start/end markers with their escaped counterparts.**
|
|
|
+ *
|
|
|
+ * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
|
|
|
+ * output when the $interpolate service processes the text. So, for HTML elements interpolated
|
|
|
+ * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
|
|
|
+ * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
|
|
|
+ * this is typically useful only when user-data is used in rendering a template from the server, or
|
|
|
+ * when otherwise untrusted data is used by a directive.
|
|
|
+ *
|
|
|
+ * <example name="interpolation">
|
|
|
+ * <file name="index.html">
|
|
|
+ * <div ng-init="username='A user'">
|
|
|
+ * <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
|
|
|
+ * </p>
|
|
|
+ * <p><strong>{{username}}</strong> attempts to inject code which will deface the
|
|
|
+ * application, but fails to accomplish their task, because the server has correctly
|
|
|
+ * escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
|
|
|
+ * characters.</p>
|
|
|
+ * <p>Instead, the result of the attempted script injection is visible, and can be removed
|
|
|
+ * from the database by an administrator.</p>

|
|

|
|
|
+ * </example>
|
|
|
+ *
|
|
|
+ * @knownIssue
|
|
|
+ * It is currently not possible for an interpolated expression to contain the interpolation end
|
|
|
+ * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
|
|
|
+ * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
|
|
|
+ *
|
|
|
+ * @knownIssue
|
|
|
+ * All directives and components must use the standard `{{` `}}` interpolation symbols
|
|
|
+ * in their templates. If you change the application interpolation symbols the {@link $compile}
|
|
|
+ * service will attempt to denormalize the standard symbols to the custom symbols.
|
|
|
+ * The denormalization process is not clever enough to know not to replace instances of the standard
|
|
|
+ * symbols where they would not normally be treated as interpolation symbols. For example in the following
|
|
|
+ * code snippet the closing braces of the literal object will get incorrectly denormalized:
|
|
|
+ *
|
|
|
+ * ```
|
|
|
+ * <div data-context='{"context":{"id":3,"type":"page"}}">
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * The workaround is to ensure that such instances are separated by whitespace:
|
|
|
+ * ```
|
|
|
+ * <div data-context='{"context":{"id":3,"type":"page"} }">
|
|
|
+ * ```

|

+ *
|

|
|
|
+ * run indefinitely if `count` is not defined. The value of the notification will be the

+ * number of iterations that have run.
|
|
|
+ * To cancel an interval, call `$interval.cancel(promise)`.
|
|
|
+ *
|
|
|
+ * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
|
|

|
|
|
+ * time.

|
|
+ * directive's element are destroyed.
|
|
|
+ * You should take this into consideration and make sure to always cancel the interval at the
|
|

|

|
|
|
+// content then it is possible that your application contains a security vulnerability to an XSS style attack.

|

|
+ //
|

+ // So, to ensure that we are checking the same `name` that JavaScript would use, we cast it

|
|
|
+ *
|
|
|
+ * @description
|
|
|
+ * A service that helps you run functions asynchronously, and use their return values (or exceptions)
|
|
|
+ * when they are done processing.
|
|
|
+ *
|
|
|
+ * This is a [Promises/A+](https://promisesaplus.com/)-compliant implementation of promises/deferred
|
|
|
+ * objects inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
|
|
|
+ *
|
|
|
+ * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
|
|
|
+ * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
|
|
|
+ *
|
|
|
+ * # $q constructor
|
|
|
+ *
|
|
|
+ * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
|
|
|
+ * function as the first argument. This is similar to the native Promise implementation from ES6,
|
|
|
+ * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
|
|
|
+ *
|
|
|
+ * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
|
|
|
+ * available yet.
|
|
|
+ *
|
|
|
+ * It can be used like so:
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * // for the purpose of this example let's assume that variables `$q` and `okToGreet`
|
|
|
+ * // are available in the current lexical scope (they could have been injected or passed in).
|
|
|
+ *
|
|
|
+ * function asyncGreet(name) {
|
|
|
+ * // perform some asynchronous operation, resolve or reject the promise when appropriate.
|
|
|
+ * return $q(function(resolve, reject) {
|
|
|
+ * setTimeout(function() {
|
|
|
+ * if (okToGreet(name)) {
|
|
|
+ * resolve('Hello, ' + name + '!');
|
|
|
+ * } else {
|
|
|
+ * reject('Greeting ' + name + ' is not allowed.');
|
|
|
+ * }
|
|
|
+ * }, 1000);
|
|
|
+ * });
|
|
|
+ * }
|
|
|
+ *
|
|
|
+ * var promise = asyncGreet('Robin Hood');
|
|
|
+ * promise.then(function(greeting) {
|
|
|
+ * alert('Success: ' + greeting);
|
|
|
+ * }, function(reason) {
|
|
|
+ * alert('Failed: ' + reason);
|
|
|
+ * });
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
|
|
|
+ *
|
|
|
+ * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
|
|
|
+ *
|
|
|
+ * However, the more traditional CommonJS-style usage is still available, and documented below.
|
|
|
+ *
|
|
|
+ * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
|
|
|
+ * interface for interacting with an object that represents the result of an action that is
|
|
|
+ * performed asynchronously, and may or may not be finished at any given point in time.
|
|
|
+ *
|
|
|
+ * From the perspective of dealing with error handling, deferred and promise APIs are to
|
|
|
+ * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * // for the purpose of this example let's assume that variables `$q` and `okToGreet`
|
|
|
+ * // are available in the current lexical scope (they could have been injected or passed in).
|
|
|
+ *
|
|
|
+ * function asyncGreet(name) {
|
|
|
+ * var deferred = $q.defer();
|
|
|
+ *
|
|
|
+ * setTimeout(function() {
|
|
|
+ * deferred.notify('About to greet ' + name + '.');
|
|
|
+ *
|
|
|
+ * if (okToGreet(name)) {
|
|
|
+ * deferred.resolve('Hello, ' + name + '!');
|
|
|
+ * } else {
|
|
|
+ * deferred.reject('Greeting ' + name + ' is not allowed.');
|
|
|
+ * }
|
|
|
+ * }, 1000);
|
|
|
+ *
|
|
|
+ * return deferred.promise;
|
|
|
+ * }
|
|
|
+ *
|
|
|
+ * var promise = asyncGreet('Robin Hood');
|
|
|
+ * promise.then(function(greeting) {
|
|
|
+ * alert('Success: ' + greeting);
|
|
|
+ * }, function(reason) {
|
|
|
+ * alert('Failed: ' + reason);
|
|
|
+ * }, function(update) {
|
|
|
+ * alert('Got notification: ' + update);
|
|
|
+ * });
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
|
|
|
+ * comes in the way of guarantees that promise and deferred APIs make, see
|
|
|
+ * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
|
|
|
+ *
|
|
|
+ * Additionally the promise api allows for composition that is very hard to do with the
|
|
|
+ * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
|
|
|
+ * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
|
|
|
+ * section on serial or parallel joining of promises.

|
|
|
+ * # The Deferred API
|
|
|
+ *
|
|
|
+ * A new instance of deferred is constructed by calling `$q.defer()`.
|
|
|
+ *
|
|
|
+ * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
|
|
|
+ * that can be used for signaling the successful or unsuccessful completion, as well as the status
|
|
|
+ * of the task.
|
|
|
+ *
|
|
|
+ * **Methods**
|
|
|
+ *
|
|
|
+ * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
|
|
|
+ * constructed via `$q.reject`, the promise will be rejected instead.
|
|
|
+ * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
|
|
|
+ * resolving it with a rejection constructed via `$q.reject`.
|
|
|
+ * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
|
|
|
+ * multiple times before the promise is either resolved or rejected.
|
|
|
+ *
|
|
|
+ * **Properties**
|
|
|
+ *
|
|
|
+ * - promise – `{Promise}` – promise object associated with this deferred.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * # The Promise API
|
|
|
+ *
|
|
|
+ * A new promise instance is created when a deferred instance is created and can be retrieved by
|
|
|
+ * calling `deferred.promise`.
|
|
|
+ *
|
|
|
+ * The purpose of the promise object is to allow for interested parties to get access to the result
|
|
|
+ * of the deferred task when it completes.
|
|
|
+ *
|
|
|
+ * **Methods**
|
|
|
+ *
|
|
|
+ * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
|
|
|
+ * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
|
|
|
+ * as soon as the result is available. The callbacks are called with a single argument: the result
|
|
|
+ * or rejection reason. Additionally, the notify callback may be called zero or more times to
|
|
|
+ * provide a progress indication, before the promise is resolved or rejected.
|
|
|
+ *
|
|
|
+ * This method *returns a new promise* which is resolved or rejected via the return value of the
|
|
|
+ * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
|
|
|
+ * with the value which is resolved in that promise using
|
|
|
+ * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
|
|
|
+ * It also notifies via the return value of the `notifyCallback` method. The promise cannot be
|
|
|
+ * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
|
|
|
+ * arguments are optional.
|
|
|
+ *
|
|
|
+ * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
|
|
|
+ *
|
|
|
+ * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
|
|
|
+ * but to do so without modifying the final value. This is useful to release resources or do some
|
|
|
+ * clean-up that needs to be done whether the promise was rejected or resolved. See the [full
|
|
|
+ * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
|
|
|
+ * more information.
|
|
|
+ *
|
|
|
+ * # Chaining promises
|
|
|
+ *
|
|
|
+ * Because calling the `then` method of a promise returns a new derived promise, it is easily
|
|
|
+ * possible to create a chain of promises:
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * promiseB = promiseA.then(function(result) {
|
|
|
+ * return result + 1;
|
|
|
+ * });
|
|
|
+ *
|
|
|
+ * // promiseB will be resolved immediately after promiseA is resolved and its value
|
|
|
+ * // will be the result of promiseA incremented by 1
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * It is possible to create chains of any length and since a promise can be resolved with another
|
|
|
+ * promise (which will defer its resolution further), it is possible to pause/defer resolution of
|
|
|
+ * the promises at any point in the chain. This makes it possible to implement powerful APIs like
|
|
|
+ * $http's response interceptors.

|
+ * # Differences between Kris Kowal's Q and $q
|
|
|
+ *
|
|
|
+ * There are two main differences:
|
|
|
+ *
|
|
|
+ * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
|
|
|
+ * mechanism in angular, which means faster propagation of resolution or rejection into your
|
|
|
+ * models and avoiding unnecessary browser repaints, which would result in flickering UI.
|
|
|
+ * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
|
|
|
+ * all the important functionality needed for common async tasks.
|
|
|
+ *
|
|
|
+ * # Testing
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * it('should simulate promise', inject(function($q, $rootScope) {
|
|
|
+ * var deferred = $q.defer();
|
|
|
+ * var promise = deferred.promise;
|
|
|
+ * var resolvedValue;
|
|
|
+ *
|
|
|
+ * promise.then(function(value) { resolvedValue = value; });
|
|
|
+ * expect(resolvedValue).toBeUndefined();
|
|
|
+ *
|
|
|
+ * // Simulate resolving of promise
|
|
|
+ * deferred.resolve(123);
|
|
|
+ * // Note that the 'then' function does not get called synchronously.
|
|
|
+ * // This is because we want the promise API to always be async, whether or not
|
|
|
+ * // it got called synchronously or asynchronously.
|
|
|
+ * expect(resolvedValue).toBeUndefined();
|
|
|

|
+ * $rootScope.$apply();
|

|
|
|
+ * DESIGN NOTES
|
|
|
+ *
|
|
|
+ * The design decisions behind the scope are heavily favored for speed and memory consumption.
|
|
|
+ *
|
|
|
+ * The typical use of scope is to watch the expressions, which most of the time return the same
|
|
|
+ * value as last time so we optimize the operation.
|
|
|
+ *
|
|
|
+ * Closures construction is expensive in terms of speed as well as memory:
|
|
|
+ * - No closures, instead use prototypical inheritance for API
|
|
|
+ * - Internal state needs to be stored on scope directly, which means that private state is
|
|
|
+ * exposed as $$____ properties
|
|
|
+ *
|
|
|
+ * Loop operations are optimized by using while(count--) { ... }
|
|
|
+ * - This means that in order to keep the same order of execution as addition we have to add
|
|
|
+ * items to the array at the beginning (unshift) instead of at the end (push)
|
|
|
+ *
|
|
|
+ * Child scopes are created and removed often
|
|
|
+ * - Using an array would be slow since inserts in the middle are expensive; so we use linked lists
|
|
|
+ *
|
|
|
+ * There are fewer watches than observers. This is why you don't want the observer to be implemented
|
|
|
+ * in the same way as watch. Watch requires return of the initialization function which is expensive
|
|
|
+ * to construct.

|
|
|
+ * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
|
|
|

+ * its value when executed multiple times with the same input because it may be executed multiple
|
|
|
+ * times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
|
|
|
+ * [idempotent](http://en.wikipedia.org/wiki/Idempotence).)
|
|
|
+ * - The `listener` is called only when the value from the current `watchExpression` and the
|
|
|
+ * previous call to `watchExpression` are not equal (with the exception of the initial run,
|
|
|
+ * see below). Inequality is determined according to reference inequality,
|
|
|
+ * [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
|
|
|
+ * via the `!==` Javascript operator, unless `objectEquality == true`
|
|
|
+ * (see next point)
|
|
|
+ * - When `objectEquality == true`, inequality of the `watchExpression` is determined
|
|
|
+ * according to the {@link angular.equals} function. To save the value of the object for
|
|
|
+ * later comparison, the {@link angular.copy} function is used. This therefore means that
|
|
|
+ * watching complex objects will have adverse memory and performance implications.
|
|
|
+ * - This should not be used to watch for changes in objects that are
|
|
|
+ * or contain [File](https://developer.mozilla.org/docs/Web/API/File) objects due to limitations with {@link angular.copy `angular.copy`}.
|
|
|
+ * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
|
|
|
+ * This is achieved by rerunning the watchers until no changes are detected. The rerun
|
|
|
+ * iteration limit is 10 to prevent an infinite loop deadlock.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
|
|
|
+ * you can register a `watchExpression` function with no `listener`. (Be prepared for
|
|
|
+ * multiple calls to your `watchExpression` because it will execute multiple times in a
|
|
|
+ * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
|
|
|
+ *
|
|
|
+ * After a watcher is registered with the scope, the `listener` fn is called asynchronously
|
|
|
+ * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
|
|
|
+ * watcher. In rare cases, this is undesirable because the listener is called when the result
|
|
|
+ * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
|
|
|
+ * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
|
|
|
+ * listener was called due to initialization.

|
|

|
|
|

|

|

|
|
|
+ *
|
|
|
+ * If you want to be notified whenever `$digest()` is called,

|
|
|
+ * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict
|
|
|
+ * Contextual Escaping (SCE)} services to AngularJS.
|
|
|
+ *
|
|
|
+ * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
|
|
|
+ * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS. This is
|
|
|
+ * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to
|
|
|
+ * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
|
|
|
+ * work because `$sce` delegates to `$sceDelegate` for these operations.
|
|
|
+ *
|
|
|
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
|
|
|
+ *
|
|
|
+ * The default instance of `$sceDelegate` should work out of the box with little pain. While you
|
|
|
+ * can override it completely to change the behavior of `$sce`, the common case would
|
|
|
+ * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
|
|
|
+ * your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as
|
|
|
+ * templates. Refer {@link ng.$sceDelegateProvider#resourceUrlWhitelist

|
|
|
+ * The `$sceDelegateProvider` provider allows developers to configure the {@link ng.$sceDelegate
|
|
|
+ * $sceDelegate} service. This allows one to get/set the whitelists and blacklists used to ensure
|
|
|
+ * that the URLs used for sourcing Angular templates are safe. Refer {@link
|
|
|
+ * ng.$sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider.resourceUrlWhitelist} and
|
|
|
+ * {@link ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist}
|
|
|
+ *
|
|
|
+ * For the general details about this service in Angular, read the main page for {@link ng.$sce
|
|
|
+ * Strict Contextual Escaping (SCE)}.
|
|
|
+ *
|
|
|
+ * **Example**: Consider the following case. <a name="example"></a>
|
|
|
+ *
|
|
|
+ * - your app is hosted at url `http://myapp.example.com/`
|
|
|
+ * - but some of your templates are hosted on other domains you control such as
|
|
|
+ * `http://srv01.assets.example.com/`, `http://srv02.assets.example.com/`, etc.
|
|
|
+ * - and you have an open redirect at `http://myapp.example.com/clickThru?...`.
|
|
|
+ *
|
|
|
+ * Here is what a secure configuration for this scenario might look like:
|
|
|
+ *
|
|
|
+ * ```
|
|
|
+ * angular.module('myApp', []).config(function($sceDelegateProvider) {
|
|
|
+ * $sceDelegateProvider.resourceUrlWhitelist([
|
|
|
+ * // Allow same origin resource loads.
|
|
|
+ * 'self',
|
|
|
+ * // Allow loading from our assets domain. Notice the difference between * and **.
|
|
|
+ * 'http://srv*.assets.example.com/**'
|
|
|
+ * ]);
|
|
|
+ *
|
|
|
+ * // The blacklist overrides the whitelist so the open redirect here is blocked.
|
|
|
+ * $sceDelegateProvider.resourceUrlBlacklist([
|
|
|
+ * 'http://myapp.example.com/clickThru**'

|
|
+ * # Strict Contextual Escaping
|
|
|
+ *
|
|
|
+ * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
|
|
|
+ * contexts to result in a value that is marked as safe to use for that context. One example of
|
|
|
+ * such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer
|
|
|
+ * to these contexts as privileged or SCE contexts.
|
|
|
+ *
|
|
|
+ * As of version 1.2, Angular ships with SCE enabled by default.
|
|
|
+ *
|
|
|
+ * Note: When enabled (the default), IE<11 in quirks mode is not supported. In this mode, IE<11 allow
|
|
|
+ * one to execute arbitrary javascript by the use of the expression() syntax. Refer
|
|
|
+ * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
|
|
|
+ * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
|
|
|
+ * to the top of your HTML document.
|
|
|
+ *
|
|
|
+ * SCE assists in writing code in a way that (a) is secure by default and (b) makes auditing for
|
|
|
+ * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
|
|
|
+ *
|
|
|
+ * Here's an example of a binding in a privileged context:
|
|
|
+ *
|
|
|
+ * ```
|
|
|
+ * <input ng-model="userHtml" aria-label="User input">
|
|
|
+ * <div ng-bind-html="userHtml"></div>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE
|
|
|
+ * disabled, this application allows the user to render arbitrary HTML into the DIV.
|
|
|
+ * In a more realistic example, one may be rendering user comments, blog articles, etc. via
|
|
|
+ * bindings. (HTML is just one example of a context where rendering user controlled input creates
|
|
|
+ * security vulnerabilities.)
|
|
|
+ *
|
|
|
+ * For the case of HTML, you might use a library, either on the client side, or on the server side,
|
|
|
+ * to sanitize unsafe HTML before binding to the value and rendering it in the document.
|
|
|
+ *
|
|
|
+ * How would you ensure that every place that used these types of bindings was bound to a value that
|
|
|
+ * was sanitized by your library (or returned as safe for rendering by your server?) How can you
|
|
|
+ * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
|
|
|
+ * properties/fields and forgot to update the binding to the sanitized value?
|
|
|
+ *
|
|
|
+ * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
|
|
|
+ * determine that something explicitly says it's safe to use a value for binding in that
|
|
|
+ * context. You can then audit your code (a simple grep would do) to ensure that this is only done
|
|
|
+ * for those values that you can easily tell are safe - because they were received from your server,
|
|
|
+ * sanitized by your library, etc. You can organize your codebase to help with this - perhaps
|
|
|
+ * allowing only the files in a specific directory to do this. Ensuring that the internal API
|
|
|
+ * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
|
|
|
+ *
|
|
|
+ * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
|
|
|
+ * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
|
|
|
+ * obtain values that will be accepted by SCE / privileged contexts.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ## How does it work?
|
|
|
+ *
|
|
|
+ * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
|
|
|
+ * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link
|
|
|
+ * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
|
|
|
+ * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
|
|
|
+ *
|
|
|
+ * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
|
|
|
+ * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly
|
|
|
+ * simplified):
|
|
|
+ *
|
|
|
+ * ```
|

|
|
|
+ * ## Impact on loading templates
|
|
|
+ *
|
|
|
+ * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
|
|
|
+ * `templateUrl`'s specified by {@link guide/directive directives}.
|
|
|
+ *
|
|
|
+ * By default, Angular only loads templates from the same domain and protocol as the application
|
|
|
+ * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl
|
|
|
+ * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
|
|
|
+ * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
|
|
|
+ * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
|
|
|
+ *
|
|
|
+ * *Please note*:
|
|
|
+ * The browser's
|
|
|
+ * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
|
|
|
+ * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
|
|
|
+ * policy apply in addition to this and may further restrict whether the template is successfully
|
|
|
+ * loaded. This means that without the right CORS policy, loading templates from a different domain
|
|
|
+ * won't work on all browsers. Also, loading templates from `file://` URL does not work on some
|
|
|
+ * browsers.
|
|
|
+ *
|
|
|
+ * ## This feels like too much overhead
|
|
|
+ *
|
|
|
+ * It's important to remember that SCE only applies to interpolation expressions.
|
|
|
+ *
|
|
|
+ * If your expressions are constant literals, they're automatically trusted and you don't need to
|
|
|
+ * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
|
|
|
+ * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works.
|
|
|
+ *
|
|
|
+ * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
|
|
|
+ * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here.
|
|
|
+ *
|
|
|
+ * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
|
|
|
+ * templates in `ng-include` from your application's domain without having to even know about SCE.
|
|
|
+ * It blocks loading templates from other domains or loading templates over http from an https
|
|
|
+ * served document. You can change these by setting your own custom {@link
|
|
|
+ * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
|
|
|
+ * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
|
|
|
+ *
|
|
|
+ * This significantly reduces the overhead. It is far easier to pay the small overhead and have an
|
|
|
+ * application that's secure and can be audited to verify that with much more ease than bolting
|
|
|
+ * security onto an application later.

|
|
+ * ## What trusted context types are supported?
|
|
|
+ *
|
|
|
+ * | Context | Notes |
|
|
|
+ * |---------------------|----------------|
|
|
|
+ * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
|
|
|
+ * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. |
|
|
|
+ * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. |
|
|
|
+ * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG`, `VIDEO`, `AUDIO`, `SOURCE`, and `TRACK` (e.g. `IFRAME`, `OBJECT`, etc.) <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
|
|
|
+ * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. |
|
|
|
+ *
|
|
|
+ * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
|
|
|
+ *
|
|
|
+ * Each element in these arrays must be one of the following:
|
|
|
+ *
|
|
|
+ * - **'self'**
|
|
|
+ * - The special **string**, `'self'`, can be used to match against all URLs of the **same
|
|
|
+ * domain** as the application document using the **same protocol**.
|
|
|
+ * - **String** (except the special value `'self'`)
|
|
|
+ * - The string is matched against the full *normalized / absolute URL* of the resource
|
|
|
+ * being tested (substring matches are not good enough.)
|
|
|
+ * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters
|
|
|
+ * match themselves.
|
|
|
+ * - `*`: matches zero or more occurrences of any character other than one of the following 6
|
|
|
+ * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use
|
|
|
+ * in a whitelist.
|
|
|
+ * - `**`: matches zero or more occurrences of *any* character. As such, it's not
|
|
|
+ * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g.
|
|
|
+ * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
|
|
|
+ * not have been the intention.) Its usage at the very end of the path is ok. (e.g.
|
|
|
+ * http://foo.example.com/templates/**).
|
|
|
+ * - **RegExp** (*see caveat below*)
|
|
|
+ * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax
|
|
|
+ * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to
|
|
|
+ * accidentally introduce a bug when one updates a complex expression (imho, all regexes should
|
|
|
+ * have good test coverage). For instance, the use of `.` in the regex is correct only in a
|
|
|
+ * small number of cases. A `.` character in the regex used when matching the scheme or a
|
|
|
+ * subdomain could be matched against a `:` or literal `.` that was likely not intended. It
|
|
|
+ * is highly recommended to use the string patterns and only fall back to regular expressions
|
|
|
+ * as a last resort.
|
|
|
+ * - The regular expression must be an instance of RegExp (i.e. not a string.) It is
|
|
|
+ * matched against the **entire** *normalized / absolute URL* of the resource being tested
|
|
|
+ * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags
|
|
|
+ * present on the RegExp (such as multiline, global, ignoreCase) are ignored.
|
|
|
+ * - If you are generating your JavaScript from some other templating engine (not
|
|
|
+ * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
|
|
|
+ * remember to escape your regular expression (and be aware that you might need more than
|
|
|
+ * one level of escaping depending on your templating engine and the way you interpolated
|
|
|
+ * the value.) Do make use of your platform's escaping mechanism as it might be good
|
|
|
+ * enough before coding your own. E.g. Ruby has
|
|
|
+ * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
|
|
|
+ * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
|
|
|
+ * Javascript lacks a similar built in function for escaping. Take a look at Google
|
|
|
+ * Closure library's [goog.string.regExpEscape(s)](
|
|
|
+ * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
|
|

+ *

|
|
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

|
|
|
+ *
|
|
|
+ * Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits
|
|
|
+ * for little coding overhead. It will be much harder to take an SCE disabled application and
|
|
|
+ * either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE
|
|
|
+ * for cases where you have a lot of existing code that was written before SCE was introduced and
|
|
|
+ * you're migrating them a module at a time.
|
|
|
+ *
|
|
|
+ * That said, here's how you can completely disable SCE:
|
|
|
+ *
|
|
|
+ * ```
|
|
|
+ * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
|
|
|
+ * // Completely disable SCE. For demonstration purposes only!
|
|
|
+ * // Do not use in new projects.
|
|
|
+ * $sceProvider.enabled(false);
|
|
|
+ * });
|
|
|
+ * ```

+ /* Design notes on the default implementation for SCE.
|
|
|
+ *
|
|
|
+ * The API contract for the SCE delegate
|
|
|
+ * -------------------------------------
|
|
|
+ * The SCE delegate object must provide the following 3 methods:
|
|
|
+ *
|
|
|
+ * - trustAs(contextEnum, value)
|
|
|
+ * This method is used to tell the SCE service that the provided value is OK to use in the
|
|
|
+ * contexts specified by contextEnum. It must return an object that will be accepted by
|
|
|
+ * getTrusted() for a compatible contextEnum and return this value.
|
|
|
+ *
|
|
|
+ * - valueOf(value)
|
|
|
+ * For values that were not produced by trustAs(), return them as is. For values that were
|
|
|
+ * produced by trustAs(), return the corresponding input value to trustAs. Basically, if
|
|
|
+ * trustAs is wrapping the given values into some type, this operation unwraps it when given
|
|
|
+ * such a value.
|
|
|
+ *
|
|
|
+ * - getTrusted(contextEnum, value)
|
|
|
+ * This function should return the a value that is safe to use in the context specified by
|
|
|
+ * contextEnum or throw and exception otherwise.
|
|
|
+ *
|
|
|
+ * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
|
|
|
+ * opaque or wrapped in some holder object. That happens to be an implementation detail. For
|
|
|
+ * instance, an implementation could maintain a registry of all trusted objects by context. In
|
|
|
+ * such a case, trustAs() would return the same object that was passed in. getTrusted() would
|
|
|
+ * return the same object passed in if it was found in the registry under a compatible context or
|
|
|
+ * throw an exception otherwise. An implementation might only wrap values some of the time based
|
|
|
+ * on some criteria. getTrusted() might return a value and not throw an exception for special
|
|
|
+ * constants or objects even if not wrapped. All such implementations fulfill this contract.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * A note on the inheritance model for SCE contexts
|
|
|
+ * ------------------------------------------------
|
|
|
+ * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This
|
|
|
+ * is purely an implementation details.
|
|
|
+ *
|
|
|
+ * The contract is simply this:
|
|
|
+ *
|
|
|
+ * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
|
|
|
+ * will also succeed.
|
|
|
+ *
|
|
|
+ * Inheritance happens to capture this in a natural way. In some future, we
|
|
|
+ * may not use inheritance anymore. That is OK because no code outside of
|
|
|
+ * sce.js and sceSpecs.js would need to be aware of this detail.

|
|
|
+ * Implementation Notes for non-IE browsers
|
|
|
+ * ----------------------------------------
|
|
|
+ * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
|
|
|
+ * results both in the normalizing and parsing of the URL. Normalizing means that a relative
|
|
|
+ * URL will be resolved into an absolute URL in the context of the application document.
|
|
|
+ * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
|
|
|
+ * properties are all populated to reflect the normalized URL. This approach has wide
|
|
|
+ * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See
|
|
|
+ * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
|
|
|
+ *
|
|
|
+ * Implementation Notes for IE
|
|
|
+ * ---------------------------
|
|
|
+ * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
|
|
|
+ * browsers. However, the parsed components will not be set if the URL assigned did not specify
|
|
|
+ * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We
|
|
|
+ * work around that by performing the parsing in a 2nd step by taking a previously normalized
|
|
|
+ * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the
|
|
|
+ * properties such as protocol, hostname, port, etc.

|
|
|
+ * @description
|
|
|
+ * Selects a subset of items from `array` and returns it as a new array.
|
|
|
+ *
|
|
|
+ * @param {Array} array The source array.
|
|
|
+ * @param {string|Object|function()} expression The predicate to be used for selecting items from
|
|
|
+ * `array`.
|
|
|
+ *
|
|
|
+ * Can be one of:
|
|
|
+ *
|
|
|
+ * - `string`: The string is used for matching against the contents of the `array`. All strings or
|
|
|
+ * objects with string properties in `array` that match this string will be returned. This also
|
|
|
+ * applies to nested object properties.
|
|
|
+ * The predicate can be negated by prefixing the string with `!`.
|
|
|
+ *
|
|
|
+ * - `Object`: A pattern object can be used to filter specific properties on objects contained
|
|
|
+ * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
|
|
|
+ * which have property `name` containing "M" and property `phone` containing "1". A special
|
|
|
+ * property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
|
|
|
+ * against any property of the object or its nested object properties. That's equivalent to the
|
|
|
+ * simple substring match with a `string` as described above. The special property name can be
|
|
|
+ * overwritten, using the `anyPropertyKey` parameter.
|
|
|
+ * The predicate can be negated by prefixing the string with `!`.
|
|
|
+ * For example `{name: "!M"}` predicate will return an array of items which have property `name`
|
|
|
+ * not containing "M".
|
|
|
+ *
|
|
|
+ * Note that a named property will match properties on the same level only, while the special
|
|
|
+ * `$` property will match properties on the same level or deeper. E.g. an array item like
|
|
|
+ * `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
|
|
|
+ * **will** be matched by `{$: 'John'}`.
|
|
|
+ *
|
|
|
+ * - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
|
|
|
+ * The function is called for each element of the array, with the element, its index, and
|
|
|
+ * the entire array itself as arguments.
|
|
|
+ *
|
|
|
+ * The final result is an array of those elements that the predicate returned true for.
|
|
|
+ *
|
|
|
+ * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in
|
|
|
+ * determining if the expected value (from the filter expression) and actual value (from
|
|
|
+ * the object in the array) should be considered a match.
|
|
|
+ *
|
|
|
+ * Can be one of:
|
|
|
+ *
|
|
|
+ * - `function(actual, expected)`:
|
|
|
+ * The function will be given the object value and the predicate value to compare and
|
|
|
+ * should return true if both values should be considered equal.
|
|
|
+ *
|
|
|
+ * - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
|
|
|
+ * This is essentially strict comparison of expected and actual.
|
|
|
+ *
|
|
|
+ * - `false`: A short hand for a function which will look for a substring match in a case
|
|
|
+ * insensitive way. Primitive values are converted to strings. Objects are not compared against
|
|
|
+ * primitives, unless they have a custom `toString` method (e.g. `Date` objects).
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * Defaults to `false`.
|
|
|
+ *
|
|
|
+ * @param {string} [anyPropertyKey] The special property name that matches against any property.
|
|
|
+ * By default `$`.

|
|
|
+ * * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
|
|
|
+ *
|
|

|
|
|
+ * {@link guide/i18n localizable formats}:
|
|
|
+ *
|
|
|

|
|
|
+ *
|
|
|
+ * `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
|
|
|
+ * `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
|
|
|
+ * (e.g. `"h 'o''clock'"`).
|
|
|
+ *
|
|
|
+ * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
|
|
|
+ * number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
|
|
|
+ * shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
|
|
|
+ * specified in the string input, the time is considered to be in the local timezone.
|
|
|
+ * @param {string=} format Formatting rules (see Description). If not specified,
|
|
|
+ * `mediumDate` is used.
|
|
|
+ * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
|
|
|
+ * continental US time zone abbreviations, but for general use, use a time zone offset, for
|
|
|
+ * example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
|
|
|
+ * If not specified, the timezone of the browser will be used.
|
|
|
+ * @returns {string} Formatted string or the input if input is not recognized as date/millis.

|
|
|
+ * is positive, `limit` number of items from the beginning of the source array/string are copied.
|
|
|
+ * If the number is negative, `limit` number of items from the end of the source array/string

|
|
|
+ * @kind function
|
|
|
+ *
|
|
|
+ * @description
|
|
|
+ * Returns an array containing the items from the specified `collection`, ordered by a `comparator`
|
|
|
+ * function based on the values computed using the `expression` predicate.
|
|
|
+ *
|
|
|
+ * For example, `[{id: 'foo'}, {id: 'bar'}] | orderBy:'id'` would result in
|
|
|
+ * `[{id: 'bar'}, {id: 'foo'}]`.
|
|
|
+ *
|
|
|
+ * The `collection` can be an Array or array-like object (e.g. NodeList, jQuery object, TypedArray,
|
|
|
+ * String, etc).
|
|
|
+ *
|
|
|
+ * The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
|
|
|
+ * for the preceding one. The `expression` is evaluated against each item and the output is used
|
|
|
+ * for comparing with other items.
|
|
|
+ *
|
|
|
+ * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
|
|
|
+ * ascending order.
|
|
|
+ *
|
|
|
+ * The comparison is done using the `comparator` function. If none is specified, a default, built-in
|
|
|
+ * comparator is used (see below for details - in a nutshell, it compares numbers numerically and
|
|
|
+ * strings alphabetically).
|
|
|
+ *
|
|
|
+ * ### Under the hood
|
|
|
+ *
|
|
|
+ * Ordering the specified `collection` happens in two phases:
|
|
|
+ *
|
|
|
+ * 1. All items are passed through the predicate (or predicates), and the returned values are saved
|
|
|
+ * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
|
|
|
+ * through a predicate that extracts the value of the `label` property, would be transformed to:
|
|
|
+ * ```
|
|
|
+ * {
|
|
|
+ * value: 'foo',
|
|
|
+ * type: 'string',
|
|
|
+ * index: ...
|
|
|
+ * }
|
|
|
+ * ```
|
|
|
+ * 2. The comparator function is used to sort the items, based on the derived values, types and
|
|
|
+ * indices.
|
|
|
+ *
|
|
|
+ * If you use a custom comparator, it will be called with pairs of objects of the form
|
|
|
+ * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
|
|
|
+ * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
|
|
|
+ * second, or `1` otherwise.
|
|
|
+ *
|
|
|
+ * In order to ensure that the sorting will be deterministic across platforms, if none of the
|
|
|
+ * specified predicates can distinguish between two items, `orderBy` will automatically introduce a
|
|
|
+ * dummy predicate that returns the item's index as `value`.
|
|
|
+ * (If you are using a custom comparator, make sure it can handle this predicate as well.)
|
|
|
+ *
|
|
|
+ * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
|
|
|
+ * value for an item, `orderBy` will try to convert that object to a primitive value, before passing
|
|
|
+ * it to the comparator. The following rules govern the conversion:
|
|
|
+ *
|
|
|
+ * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
|
|
|
+ * used instead.<br />
|
|
|
+ * (If the object has a `valueOf()` method that returns another object, then the returned object
|
|
|
+ * will be used in subsequent steps.)
|
|
|
+ * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that
|
|
|
+ * returns a primitive, its return value will be used instead.<br />
|
|
|
+ * (If the object has a `toString()` method that returns another object, then the returned object
|
|
|
+ * will be used in subsequent steps.)
|
|
|
+ * 3. No conversion; the object itself is used.
|
|
|
+ *
|
|
|
+ * ### The default comparator
|
|
|
+ *
|
|
|
+ * The default, built-in comparator should be sufficient for most usecases. In short, it compares
|
|
|
+ * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to
|
|
|
+ * using their index in the original collection, and sorts values of different types by type.
|
|
|
+ *
|
|
|
+ * More specifically, it follows these steps to determine the relative order of items:
|
|
|
+ *
|
|
|
+ * 1. If the compared values are of different types, compare the types themselves alphabetically.
|
|
|
+ * 2. If both values are of type `string`, compare them alphabetically in a case- and
|
|
|
+ * locale-insensitive way.
|
|
|
+ * 3. If both values are objects, compare their indices instead.
|
|
|
+ * 4. Otherwise, return:
|
|
|
+ * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`).
|
|
|
+ * - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator).
|
|
|
+ * - `1`, otherwise.
|
|
|
+ *
|
|
|
+ * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being
|
|
|
+ * saved as numbers and not strings.
|
|
|
+ * **Note:** For the purpose of sorting, `null` values are treated as the string `'null'` (i.e.
|
|
|
+ * `type: 'string'`, `value: 'null'`). This may cause unexpected sort order relative to
|
|
|
+ * other values.
|
|
|
+ *
|
|
|
+ * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.
|
|
|
+ * @param {(Function|string|Array.<Function|string>)=} expression - A predicate (or list of
|
|
|
+ * predicates) to be used by the comparator to determine the order of elements.
|
|
|
+ *
|
|
|
+ * Can be one of:
|
|
|
+ *
|
|
|
+ * - `Function`: A getter function. This function will be called with each item as argument and
|
|
|
+ * the return value will be used for sorting.
|
|
|
+ * - `string`: An Angular expression. This expression will be evaluated against each item and the
|
|
|
+ * result will be used for sorting. For example, use `'label'` to sort by a property called
|
|
|
+ * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
|
|
|
+ * property.<br />
|
|
|
+ * (The result of a constant expression is interpreted as a property name to be used for
|
|
|
+ * comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a
|
|
|
+ * property called `special name`.)<br />
|
|
|
+ * An expression can be optionally prefixed with `+` or `-` to control the sorting direction,
|
|
|
+ * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,
|
|
|
+ * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.
|
|
|
+ * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the
|
|
|
+ * relative order of two items, the next predicate is used as a tie-breaker.
|
|
|
+ *
|
|
|
+ * **Note:** If the predicate is missing or empty then it defaults to `'+'`.
|
|
|
+ *
|
|
|
+ * @param {boolean=} reverse - If `true`, reverse the sorting order.
|
|
|
+ * @param {(Function)=} comparator - The comparator function used to determine the relative order of
|
|
|
+ * value pairs. If omitted, the built-in comparator will be used.
|
|
|
+ *
|
|
|
+ * @returns {Array} - The sorted array.

|
|
+ * @example
|
|
|
+ * ### Ordering a table with `ngRepeat`
|
|
|
+ *
|
|
|
+ * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by
|
|
|
+ * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means
|
|
|
+ * it defaults to the built-in comparator.

|
|
|
+ *
|
|
|
+ * If you have very specific requirements about the way items are sorted, you can pass your own
|
|
|

|
|
|
+ * way. (When specifying a custom comparator, you also need to pass a value for the `reverse`
|
|
|
+ * argument - passing `false` retains the default sorting order, i.e. ascending.)

|
|
|
+ * Using Angular markup like `{{hash}}` in an href attribute will
|
|
|
+ * make the link go to the wrong URL if the user clicks it before
|
|
|
+ * Angular has a chance to replace the `{{hash}}` markup with its
|
|
|
+ * value. Until Angular replaces the markup the link will be broken
|
|
|
+ * and will most likely return a 404 error. The `ngHref` directive

|
|
|
+ *
|
|
|
+ * In Angular, forms can be nested. This means that the outer form is valid when all of the child
|
|
|
+ * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
|
|
|
+ * Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to
|
|
|
+ * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group
|
|
|
+ * of controls needs to be determined.
|
|
|
+ *
|
|
|
+ * # CSS classes
|
|
|
+ * - `ng-valid` is set if the form is valid.
|
|
|
+ * - `ng-invalid` is set if the form is invalid.
|
|
|
+ * - `ng-pending` is set if the form is pending.
|
|
|
+ * - `ng-pristine` is set if the form is pristine.
|
|
|
+ * - `ng-dirty` is set if the form is dirty.
|
|
|
+ * - `ng-submitted` is set if the form was submitted.
|
|
|
+ *
|
|
|
+ * Keep in mind that ngAnimate can detect each of these classes when added and removed.
|
|
|
+ *
|
|
|

|
|
|
+ * # Submitting a form and preventing the default action
|
|
|
+ *
|
|
|
+ * Since the role of forms in client-side Angular applications is different than in classical
|
|
|
+ * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
|
|
|
+ * page reload that sends the data to the server. Instead some javascript logic should be triggered
|
|
|
+ * to handle the form submission in an application-specific way.
|
|
|
+ *
|
|
|
+ * For this reason, Angular prevents the default action (form submission to the server) unless the
|
|
|
+ * `<form>` element has an `action` attribute specified.
|
|
|
+ *
|
|
|
+ * You can use one of the following two ways to specify what javascript method should be called when
|
|
|
+ * a form is submitted:
|
|
|
+ *
|
|
|
+ * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
|
|
|
+ * - {@link ng.directive:ngClick ngClick} directive on the first
|
|
|
+ * button or input field of type submit (input[type=submit])
|
|
|
+ *
|
|
|
+ * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
|
|
|
+ * or {@link ng.directive:ngClick ngClick} directives.
|
|
|
+ * This is because of the following form submission rules in the HTML specification:
|
|
|
+ *
|
|
|
+ * - If a form has only one input field then hitting enter in this field triggers form submit
|
|
|
+ * (`ngSubmit`)
|
|
|
+ * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
|
|
|
+ * doesn't trigger submit
|
|
|
+ * - if a form has one or more input fields and one or more buttons or input[type=submit] then
|
|
|
+ * hitting enter in any of the input fields will trigger the click handler on the *first* button or
|
|
|
+ * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
|
|
|
+ *
|
|
|
+ * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
|
|
|
+ * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
|
|
|
+ * to have access to the updated model.
|
|
|
+ *
|
|
|
+ * ## Animation Hooks
|
|
|
+ *
|
|
|
+ * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
|
|
|
+ * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
|
|
|
+ * other validations that are performed within the form. Animations in ngForm are similar to how
|
|
|
+ * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
|
|
|
+ * as JS animations.
|
|
|
+ *
|
|
|
+ * The following example shows a simple way to utilize CSS transitions to style a form element
|
|
|
+ * that has been rendered as invalid after it has been validated:
|
|
|
+ *
|
|
|
+ * <pre>
|
|
|
+ * //be sure to include ngAnimate as a module to hook into more
|
|
|
+ * //advanced animations
|
|
|
+ * .my-form {
|
|
|
+ * transition:0.5s linear all;
|
|
|
+ * background: white;
|
|
|
+ * }
|
|
|
+ * .my-form.ng-invalid {
|
|
|
+ * background: red;
|
|
|
+ * color:white;
|
|
|
+ * }
|
|
|
+ * </pre>
|
|
|
+ *

|

|
|
|
+ * @description
|
|
|
+ * Standard HTML text input with angular data binding, inherited by most of the `input` elements.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * @param {string} ngModel Assignable angular expression to data-bind to.
|
|
|
+ * @param {string=} name Property name of the form under which the control is published.
|
|
|
+ * @param {string=} required Adds `required` validation error key if the value is not entered.
|
|
|
+ * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
|
|
|
+ * the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
|
|
|
+ * `required` when you want to data-bind to the `required` attribute.
|
|
|
+ * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
|
|
|
+ * minlength.
|
|
|
+ * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
|
|
|
+ * maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
|
|
|
+ * any length.
|
|
|
+ * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
|
|
|
+ * that contains the regular expression body that will be converted to a regular expression
|
|
|
+ * as in the ngPattern directive.
|
|
|
+ * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
|
|
|
+ * does not match a RegExp found by evaluating the Angular expression given in the attribute value.
|
|
|
+ * If the expression evaluates to a RegExp object, then this is used directly.
|
|
|
+ * If the expression evaluates to a string, then it will be converted to a RegExp
|
|
|
+ * after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
|
|
|
+ * `new RegExp('^abc$')`.<br />
|
|
|
+ * **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
|
|
|
+ * start at the index of the last search's match, thus not taking the whole input value into
|
|
|
+ * account.
|
|
|
+ * @param {string=} ngChange Angular expression to be executed when input changes due to user
|
|
|
+ * interaction with the input element.
|
|
|
+ * @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.
|
|
|
+ * This parameter is ignored for input[type=password] controls, which will never trim the
|
|
|
+ * input.

|
|
|
+ * Input with time validation and transformation. In browsers that do not yet support
|
|
|
+ * the HTML5 time input, a text element will be used. In that case, the text must be entered in a valid ISO-8601
|
|
|
+ * local time format (HH:mm:ss), for example: `14:57:00`. Model must be a Date object. This binding will always output a
|
|
|
+ * Date object to the model of January 1, 1970, or local date `new Date(1970, 0, 1, HH, mm, ss)`.
|
|
|
+ *
|
|
|
+ * The model must always be a Date object, otherwise Angular will throw an error.
|
|
|
+ * Invalid `Date` objects (dates whose `getTime()` is `NaN`) will be rendered as an empty string.
|
|
|
+ *
|
|
|
+ * The timezone to be used to read/write the `Date` instance in the model can be defined using
|
|
|
+ * {@link ng.directive:ngModelOptions ngModelOptions}. By default, this is the timezone of the browser.

|
|
|
+ * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to

|
|
|
+ *
|
|
|
+ * In browsers that follow the
|
|
|
+ * [HTML5 specification](https://html.spec.whatwg.org/multipage/forms.html#number-state-%28type=number%29),
|
|
|
+ * `input[number]` does not work as expected with {@link ngModelOptions `ngModelOptions.allowInvalid`}.
|
|
|
+ * If a non-number is entered in the input, the browser will report the value as an empty string,
|
|
|
+ * which means the view / model values in `ngModel` and subsequently the scope value
|
|
|
+ * will also be an empty string.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * @param {string} ngModel Assignable angular expression to data-bind to.
|
|
|
+ * @param {string=} name Property name of the form under which the control is published.
|
|
|
+ * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
|
|
|
+ * Can be interpolated.
|
|
|
+ * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
|
|
|
+ * Can be interpolated.
|
|
|
+ * @param {string=} ngMin Like `min`, sets the `min` validation error key if the value entered is less than `ngMin`,
|
|
|
+ * but does not trigger HTML5 native validation. Takes an expression.
|
|
|
+ * @param {string=} ngMax Like `max`, sets the `max` validation error key if the value entered is greater than `ngMax`,
|
|
|
+ * but does not trigger HTML5 native validation. Takes an expression.
|
|
|
+ * @param {string=} step Sets the `step` validation error key if the value entered does not fit the `step` constraint.
|
|
|
+ * Can be interpolated.
|
|
|
+ * @param {string=} ngStep Like `step`, sets the `step` validation error key if the value entered does not fit the `ngStep` constraint,
|
|
|
+ * but does not trigger HTML5 native validation. Takes an expression.
|
|
|
+ * @param {string=} required Sets `required` validation error key if the value is not entered.
|
|
|
+ * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
|
|
|
+ * the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
|
|
|
+ * `required` when you want to data-bind to the `required` attribute.
|
|
|
+ * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
|
|
|

|
|
|
+ * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
|
|
|
+ * maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
|
|
|
+ * any length.
|
|
|
+ * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
|
|
|
+ * that contains the regular expression body that will be converted to a regular expression
|
|
|
+ * as in the ngPattern directive.
|
|
|
+ * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
|
|
|
+ * does not match a RegExp found by evaluating the Angular expression given in the attribute value.
|
|
|
+ * If the expression evaluates to a RegExp object, then this is used directly.
|
|
|
+ * If the expression evaluates to a string, then it will be converted to a RegExp
|
|
|
+ * after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
|
|
|
+ * `new RegExp('^abc$')`.<br />
|
|
|
+ * **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to

|
|

|
|
|
+ * @description
|
|
|
+ * Native range input with validation and transformation.
|
|
|
+ *
|
|
|
+ * The model for the range input must always be a `Number`.
|
|
|
+ *
|
|
|
+ * IE9 and other browsers that do not support the `range` type fall back
|
|
|
+ * to a text input without any default values for `min`, `max` and `step`. Model binding,
|
|
|
+ * validation and number parsing are nevertheless supported.
|
|
|
+ *
|
|
|
+ * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`
|
|
|
+ * in a way that never allows the input to hold an invalid value. That means:
|
|
|
+ * - any non-numerical value is set to `(max + min) / 2`.
|
|
|
+ * - any numerical value that is less than the current min val, or greater than the current max val
|
|
|
+ * is set to the min / max val respectively.
|
|
|
+ * - additionally, the current `step` is respected, so the nearest value that satisfies a step
|
|
|
+ * is used.
|
|
|
+ *
|
|
|
+ * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))
|
|
|
+ * for more info.
|
|
|
+ *
|
|
|
+ * This has the following consequences for Angular:
|
|
|
+ *
|
|
|
+ * Since the element value should always reflect the current model value, a range input
|
|
|
+ * will set the bound ngModel expression to the value that the browser has set for the
|
|
|
+ * input element. For example, in the following input `<input type="range" ng-model="model.value">`,
|
|
|
+ * if the application sets `model.value = null`, the browser will set the input to `'50'`.
|
|
|
+ * Angular will then set the model to `50`, to prevent input and model value being out of sync.
|
|
|
+ *
|
|
|
+ * That means the model for range will immediately be set to `50` after `ngModel` has been
|
|
|
+ * initialized. It also means a range input can never have the required error.
|
|
|
+ *
|
|
|
+ * This does not only affect changes to the model value, but also to the values of the `min`,
|
|
|
+ * `max`, and `step` attributes. When these change in a way that will cause the browser to modify
|
|
|
+ * the input value, Angular will also update the model value.
|
|
|
+ *
|
|
|
+ * Automatic value adjustment also means that a range input element can never have the `required`,
|
|
|
+ * `min`, or `max` errors.
|
|
|
+ *
|
|
|
+ * However, `step` is currently only fully implemented by Firefox. Other browsers have problems
|
|
|
+ * when the step value changes dynamically - they do not adjust the element value correctly, but
|
|
|
+ * instead may set the `stepMismatch` error. If that's the case, the Angular will set the `step`
|
|
|
+ * error on the input, and set the model to `undefined`.
|
|
|
+ *
|
|
|
+ * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do
|
|
|
+ * not set the `min` and `max` attributes, which means that the browser won't automatically adjust
|
|
|
+ * the input value based on their values, and will always assume min = 0, max = 100, and step = 1.

|
|
|

|
|

|
|

|
|

|
|
|

|
|
|
+ * @knownIssue
|
|
|
+ *
|
|
|
+ * When specifying the `placeholder` attribute of `<textarea>`, Internet Explorer will temporarily
|
|
|
+ * insert the placeholder value as the textarea's content. If the placeholder value contains
|
|
|
+ * interpolation (`{{ ... }}`), an error will be logged in the console when Angular tries to update
|
|
|
+ * the value of the by-then-removed text node. This doesn't affect the functionality of the
|
|
|
+ * textarea, but can be undesirable.
|
|
|
+ *
|
|
|
+ * You can work around this Internet Explorer issue by using `ng-attr-placeholder` instead of
|
|
|
+ * `placeholder` on textareas, whenever you need interpolation in the placeholder value. You can
|
|
|
+ * find more details on `ngAttr` in the
|
|
|
+ * [Interpolation](guide/interpolation#-ngattr-for-binding-to-arbitrary-attributes) section of the
|
|
|

|
+ * @description
|
|
|
+ * The `ngBind` attribute tells Angular to replace the text content of the specified HTML element
|
|
|
+ * with the value of a given expression, and to update the text content when the value of that
|
|
|
+ * expression changes.
|
|
|
+ *
|
|
|
+ * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like
|
|
|
+ * `{{ expression }}` which is similar but less verbose.
|
|
|
+ *
|
|
|
+ * It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
|
|
|
+ * displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
|
|
|
+ * element attribute, it makes the bindings invisible to the user while the page is loading.
|
|
|
+ *
|
|
|
+ * An alternative solution to this problem would be using the
|
|
|
+ * {@link ng.directive:ngCloak ngCloak} directive.

|

|
|
|
+ * Unlike `ngBind`, the `ngBindTemplate` can contain multiple `{{` `}}`
|

|
|
|

|

|

|
|
+ * ngSanitize} in your module's dependencies (not in core Angular). In order to use {@link ngSanitize}
|
|
|
+ * in your module's dependencies, you need to include "angular-sanitize.js" in your application.
|
|
|

|
|
|
+ * You may also bypass sanitization for values you know are safe. To do so, bind to
|
|
|

|
+ * under {@link ng.$sce#show-me-an-example-using-sce- Strict Contextual Escaping (SCE)}.
|

|
|
|
+ * @restrict AC
|
|
|
+ *
|
|
|
+ * @description
|
|
|
+ * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
|
|
|
+ * an expression that represents all classes to be added.
|
|
|
+ *
|
|
|
+ * The directive operates in three different ways, depending on which of three types the expression
|
|
|
+ * evaluates to:
|
|
|
+ *
|
|
|
+ * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
|
|
|
+ * names.
|
|
|
+ *
|
|
|
+ * 2. If the expression evaluates to an object, then for each key-value pair of the
|
|
|
+ * object with a truthy value the corresponding key is used as a class name.
|
|
|
+ *
|
|
|
+ * 3. If the expression evaluates to an array, each element of the array should either be a string as in
|
|
|
+ * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array
|
|
|
+ * to give you more control over what CSS classes appear. See the code below for an example of this.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * The directive won't add duplicate classes if a particular class was already set.
|
|
|
+ *
|
|
|
+ * When the expression changes, the previously added classes are removed and only then are the
|
|
|
+ * new classes added.
|
|
|
+ *
|
|
|
+ * @knownIssue
|
|
|
+ * You should not use {@link guide/interpolation interpolation} in the value of the `class`
|
|
|
+ * attribute, when using the `ngClass` directive on the same element.
|
|
|
+ * See {@link guide/interpolation#known-issues here} for more info.
|

|
|

|

|
|
|

|
|
|
+ * @param {expression} ngClass {@link guide/expression Expression} to eval. The result
|
|
|
+ * of the evaluation can be a string representing space delimited class
|
|
|
+ * names, an array, or a map of class names to boolean values. In the case of a map, the
|
|
|
+ * names of the properties whose values are truthy will be added as css classes to the
|
|
|
+ * element.

|
|
+ ## ngClass and pre-existing CSS3 Transitions/Animations
|
|
|
+ The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
|
|
|
+ Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
|
|
|
+ any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
|
|
|
+ to view the step by step details of {@link $animate#addClass $animate.addClass} and
|
|
|
+ {@link $animate#removeClass $animate.removeClass}.

|
|
|
+ * The `ngCloak` directive is used to prevent the Angular html template from being briefly
|
|
|
+ * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
|
|
|
+ * directive to avoid the undesirable flicker effect caused by the html template display.
|
|
|
+ *
|
|
|
+ * The directive can be applied to the `<body>` element, but the preferred usage is to apply
|
|
|
+ * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
|
|
|
+ * of the browser view.
|
|
|
+ *
|
|
|
+ * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
|
|
|
+ * `angular.min.js`.
|
|
|
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
|
|
|
+ *
|
|
|
+ * ```css
|
|
|
+ * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
|
|
|
+ * display: none !important;
|
|
|
+ * }
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * When this css rule is loaded by the browser, all html elements (including their children) that
|
|
|
+ * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
|
|
|
+ * during the compilation of the template it deletes the `ngCloak` element attribute, making
|
|
|
+ * the compiled element visible.
|
|
|
+ *
|
|
|
+ * For the best result, the `angular.js` script must be loaded in the head section of the html
|
|
|

|
|
|
+ * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
|
|
|
+ * supports the principles behind the Model-View-Controller design pattern.
|
|
|
+ *
|
|
|
+ * MVC components in angular:
|
|
|
+ *
|
|
|
+ * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
|
|
|
+ * are accessed through bindings.
|
|
|
+ * * View — The template (HTML with data bindings) that is rendered into the View.
|
|
|
+ * * Controller — The `ngController` directive specifies a Controller class; the class contains business
|
|
|
+ * logic behind the application to decorate the scope with functions and values
|
|
|
+ *
|
|
|
+ * Note that you can also attach controllers to the DOM by declaring it in a route definition
|
|
|
+ * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
|
|
|
+ * again using `ng-controller` in the template itself. This will cause the controller to be attached
|
|
|
+ * and executed twice.
|
|
|

|
|

|
|
|
+ *
|
|
|
+ * The controller instance can be published into a scope property by specifying
|
|
|
+ * `ng-controller="as propertyName"`.
|
|

|

|
|
|
+ * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
|
|
|
+ * also be the name of a globally accessible constructor function (deprecated, not recommended).
|
|
|
+ *
|
|
|
+ * @example
|
|
|
+ * Here is a simple form for editing user contact information. Adding, removing, clearing, and
|
|
|
+ * greeting are methods declared on the controller (see source tab). These methods can
|
|
|
+ * easily be called from the angular markup. Any changes to the data are automatically reflected
|
|
|
+ * in the View without the need for a manual update.
|
|
|
+ *
|
|
|
+ * Two different declaration styles are included below:
|
|
|
+ *
|
|
|
+ * * one binds methods and properties directly onto the controller using `this`:
|
|
|
+ * `ng-controller="SettingsController1 as settings"`
|
|
|
+ * * one injects `$scope` into the controller:
|
|
|
+ * `ng-controller="SettingsController2"`
|
|
|
+ *
|
|
|
+ * The second option is more common in the Angular community, and is generally used in boilerplates
|
|
|
+ * and in this guide. However, there are advantages to binding properties directly to the controller
|
|
|
+ * and avoiding scope.
|
|
|
+ *
|
|
|
+ * * Using `controller as` makes it obvious which controller you are accessing in the template when
|
|
|
+ * multiple controllers apply to an element.
|
|
|
+ * * If you are writing your controllers as classes you have easier access to the properties and
|
|
|
+ * methods, which will appear on the scope, from inside the controller code.
|
|
|
+ * * Since there is always a `.` in the bindings, you don't have to worry about prototypal
|
|
|
+ * inheritance masking primitives.
|
|
|
+ *
|
|
|
+ * This example demonstrates the `controller as` syntax.

|
|
|
+ *
|
|
|
+ * Angular has some features that can conflict with certain restrictions that are applied when using
|
|
|
+ * [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) rules.
|
|
|
+ *
|
|
|
+ * If you intend to implement CSP with these rules then you must tell Angular not to use these
|
|
|
+ * features.
|
|
|
+ *
|
|
|
+ * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * The following default rules in CSP affect Angular:
|
|
|
+ *
|
|
|
+ * * The use of `eval()`, `Function(string)` and similar functions to dynamically create and execute
|
|
|
+ * code from strings is forbidden. Angular makes use of this in the {@link $parse} service to
|
|
|
+ * provide a 30% increase in the speed of evaluating Angular expressions. (This CSP rule can be
|
|
|
+ * disabled with the CSP keyword `unsafe-eval`, but it is generally not recommended as it would
|
|
|
+ * weaken the protections offered by CSP.)
|
|
|
+ *
|
|
|
+ * * The use of inline resources, such as inline `<script>` and `<style>` elements, are forbidden.
|
|
|
+ * This prevents apps from injecting custom styles directly into the document. Angular makes use of
|
|
|
+ * this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}). To make these
|
|
|
+ * directives work when a CSP rule is blocking inline styles, you must link to the `angular-csp.css`
|
|
|
+ * in your HTML manually. (This CSP rule can be disabled with the CSP keyword `unsafe-inline`, but
|
|
|
+ * it is generally not recommended as it would weaken the protections offered by CSP.)
|
|
|
+ *
|
|
|
+ * If you do not provide `ngCsp` then Angular tries to autodetect if CSP is blocking dynamic code
|
|
|
+ * creation from strings (e.g., `unsafe-eval` not specified in CSP header) and automatically
|
|
|
+ * deactivates this feature in the {@link $parse} service. This autodetection, however, triggers a
|
|
|
+ * CSP error to be logged in the console:
|
|
|
+ *
|
|
|
+ * ```
|
|
|
+ * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
|
|
|
+ * script in the following Content Security Policy directive: "default-src 'self'". Note that
|
|
|
+ * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
|
|
|
+ * directive on an element of the HTML document that appears before the `<script>` tag that loads
|
|
|
+ * the `angular.js` file.
|
|
|
+ *
|
|
|
+ * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
|
|
|
+ *
|
|
|
+ * You can specify which of the CSP related Angular features should be deactivated by providing
|
|
|
+ * a value for the `ng-csp` attribute. The options are as follows:
|
|
|
+ *
|
|
|
+ * * no-inline-style: this stops Angular from injecting CSS styles into the DOM
|
|
|
+ *
|
|
|
+ * * no-unsafe-eval: this stops Angular from optimizing $parse with unsafe eval of strings
|
|
|
+ *
|
|
|
+ * You can use these values in the following combinations:
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * * No declaration means that Angular will assume that you can do inline styles, but it will do
|
|
|
+ * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous
|
|
|
+ * versions of Angular.
|
|
|
+ *
|
|
|
+ * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell Angular to deactivate both inline
|
|
|
+ * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous
|
|
|
+ * versions of Angular.
|
|
|
+ *
|
|
|
+ * * Specifying only `no-unsafe-eval` tells Angular that we must not use eval, but that we can
|
|
|
+ * inject inline styles. E.g. `<body ng-csp="no-unsafe-eval">`.
|
|
|
+ *
|
|
|
+ * * Specifying only `no-inline-style` tells Angular that we must not inject styles, but that we can
|
|
|
+ * run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp="no-inline-style">`
|
|
|
+ *
|
|
|
+ * * Specifying both `no-unsafe-eval` and `no-inline-style` tells Angular that we must not inject
|
|
|
+ * styles nor use eval, which is the same as an empty: ng-csp.
|
|
|
+ * E.g.`<body ng-csp="no-inline-style;no-unsafe-eval">`
|
|
|
+ *
|
|
|
+ * @example
|
|
|
+ * This example shows how to apply the `ngCsp` directive to the `html` tag.
|
|
|
+ ```html
|
|
|
+ <!doctype html>
|
|

|
|
|
+ * @multiElement
|
|
|
+ *
|
|
|
+ * @description
|
|
|
+ * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
|
|
|
+ * {expression}. If the expression assigned to `ngIf` evaluates to a false
|
|
|
+ * value then the element is removed from the DOM, otherwise a clone of the
|
|
|
+ * element is reinserted into the DOM.
|
|
|
+ *
|
|
|
+ * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
|
|
|
+ * element in the DOM rather than changing its visibility via the `display` css property. A common
|
|
|
+ * case when this difference is significant is when using css selectors that rely on an element's
|
|
|
+ * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
|
|
|
+ *
|
|
|
+ * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
|
|
|
+ * is created when the element is restored. The scope created within `ngIf` inherits from
|
|
|
+ * its parent scope using
|
|
|
+ * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
|
|
|
+ * An important implication of this is if `ngModel` is used within `ngIf` to bind to
|
|
|
+ * a javascript primitive defined in the parent scope. In this case any modifications made to the
|
|
|
+ * variable within the child scope will override (hide) the value in the parent scope.
|
|
|
+ *
|
|
|
+ * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
|
|
|
+ * is if an element's class attribute is directly modified after it's compiled, using something like
|
|
|
+ * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
|
|
|
+ * the added class will be lost because the original compiled state is used to regenerate the element.
|
|
|
+ *
|
|
|
+ * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
|
|
|
+ * and `leave` effects.

|
|
|

|
|
+ * current scope.
|
|
|
+ *
|
|
|
+ * <div class="alert alert-danger">
|
|
|
+ * This directive can be abused to add unnecessary amounts of logic into your templates.
|
|
|
+ * There are only a few appropriate uses of `ngInit`, such as for aliasing special properties of
|
|
|
+ * {@link ng.directive:ngRepeat `ngRepeat`}, as seen in the demo below; and for injecting data via
|
|
|
+ * server side scripting. Besides these few cases, you should use {@link guide/controller controllers}
|
|
|
+ * rather than `ngInit` to initialize values on a scope.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * <div class="alert alert-warning">
|
|
|
+ * **Note**: If you have assignment in `ngInit` along with a {@link ng.$filter `filter`}, make
|
|
|
+ * sure you have parentheses to ensure correct operator precedence:

|
|
|
+ * @name ngList
|
|
|
+ *
|
|
|
+ * @description
|
|
|
+ * Text input that converts between a delimited string and an array of strings. The default
|
|
|
+ * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
|
|
|
+ * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
|
|
|
+ *
|
|
|
+ * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
|
|
|
+ * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
|
|
|
+ * list item is respected. This implies that the user of the directive is responsible for
|
|
|
+ * dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
|
|
|
+ * tab or newline character.
|
|
|
+ * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
|
|
|
+ * when joining the list items back together) and whitespace around each list item is stripped
|
|
|
+ * before it is added to the model.

|
|
|
+ * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
|
|
|
+ * The controller contains services for data-binding, validation, CSS updates, and value formatting
|
|
|
+ * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
|
|
|
+ * listening to DOM events.
|
|
|
+ * Such DOM related logic should be provided by other directives which make use of
|
|
|
+ * `NgModelController` for data-binding to control elements.
|
|
|
+ * Angular provides this DOM logic for most {@link input `input`} elements.
|
|
|
+ * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
|
|
|
+ * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
|
|
|
+ *
|
|
|
+ * @example
|
|
|
+ * ### Custom Control Example
|
|
|
+ * This example shows how to use `NgModelController` with a custom control to achieve
|
|
|
+ * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
|
|
|
+ * collaborate together to achieve the desired result.
|
|
|
+ *
|
|
|
+ * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
|
|
|
+ * contents be edited in place by the user.
|
|
|
+ *
|
|
|
+ * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
|
|
|
+ * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
|
|
|
+ * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
|
|
|
+ * that content using the `$sce` service.
|
|
|
+ *

|
|
|
+ * @description
|
|
|
+ * Update the view value.
|
|
|
+ *
|
|
|
+ * This method should be called when a control wants to change the view value; typically,
|
|
|
+ * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
|
|
|
+ * directive calls it when the value of the input changes and {@link ng.directive:select select}
|
|
|
+ * calls it when an option is selected.
|
|
|
+ *
|
|
|
+ * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
|
|
|
+ * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
|
|
|
+ * value sent directly for processing, finally to be applied to `$modelValue` and then the
|
|
|
+ * **expression** specified in the `ng-model` attribute. Lastly, all the registered change listeners,
|
|
|
+ * in the `$viewChangeListeners` list, are called.
|
|
|
+ *
|
|
|
+ * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
|
|
|
+ * and the `default` trigger is not listed, all those actions will remain pending until one of the
|
|
|
+ * `updateOn` events is triggered on the DOM element.
|
|
|
+ * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
|
|
|
+ * directive is used with a custom debounce for this particular event.
|
|
|
+ * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
|
|
|
+ * is specified, once the timer runs out.
|
|
|
+ *
|
|
|
+ * When used with standard inputs, the view value will always be a string (which is in some cases
|
|
|
+ * parsed into another type, such as a `Date` object for `input[date]`.)
|
|
|
+ * However, custom controls might also pass objects to this method. In this case, we should make
|
|
|
+ * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
|
|
|
+ * perform a deep watch of objects, it only looks for a change of identity. If you only change
|
|
|
+ * the property of the object then ngModel will not realize that the object has changed and
|
|
|
+ * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
|
|
|
+ * not change properties of the copy once it has been passed to `$setViewValue`.
|
|
|
+ * Otherwise you may cause the model value on the scope to change incorrectly.
|
|
|
+ *
|
|
|
+ * <div class="alert alert-info">
|
|
|
+ * In any case, the value passed to the method should always reflect the current value
|
|
|
+ * of the control. For example, if you are calling `$setViewValue` for an input element,
|
|
|
+ * you should pass the input DOM value. Otherwise, the control and the scope model become
|
|
|
+ * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
|
|
|
+ * the control's DOM value in any way. If we want to change the control's DOM value
|
|
|
+ * programmatically, we should update the `ngModel` scope expression. Its new value will be
|
|
|
+ * picked up by the model controller, which will run it through the `$formatters`, `$render` it
|
|
|
+ * to update the DOM, and finally call `$validate` on it.

|
|
|
+ * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
|
|
|
+ * property on the scope using {@link ngModel.NgModelController NgModelController},
|
|
|
+ * which is created and exposed by this directive.
|
|
|
+ *
|
|
|
+ * `ngModel` is responsible for:
|
|
|
+ *
|
|
|
+ * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
|
|
|
+ * require.
|
|
|
+ * - Providing validation behavior (i.e. required, number, email, url).
|
|
|
+ * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
|
|
|
+ * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
|
|
|
+ * `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
|
|
|
+ * - Registering the control with its parent {@link ng.directive:form form}.
|
|
|
+ *
|
|
|
+ * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
|
|
|
+ * current scope. If the property doesn't already exist on this scope, it will be created
|
|
|
+ * implicitly and added to the scope.

|
|
|
+ * - {@link input[datetime-local] datetime-local}
|
|
|

|
|
|

|
|
|
+ * - {@link input[week] week}

|
|
|
+ * # Complex Models (objects or collections)
|
|
|
+ *
|
|
|
+ * By default, `ngModel` watches the model by reference, not value. This is important to know when
|
|
|
+ * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
|
|
|
+ * object or collection change, `ngModel` will not be notified and so the input will not be re-rendered.
|
|
|
+ *
|
|
|
+ * The model must be assigned an entirely new object or collection before a re-rendering will occur.
|
|
|
+ *
|
|
|
+ * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
|
|
|
+ * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
|
|
|
+ * if the select is given the `multiple` attribute.
|
|
|
+ *
|
|
|
+ * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
|
|
|
+ * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
|
|
|
+ * not trigger a re-rendering of the model.
|
|
|
+ *
|
|
|
+ * # CSS classes
|
|
|
+ * The following CSS classes are added and removed on the associated input/select/textarea element
|
|
|
+ * depending on the validity of the model.
|
|
|
+ *
|
|
|
+ * - `ng-valid`: the model is valid
|
|
|
+ * - `ng-invalid`: the model is invalid
|
|
|
+ * - `ng-valid-[key]`: for each valid key added by `$setValidity`
|
|
|
+ * - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
|
|
|
+ * - `ng-pristine`: the control hasn't been interacted with yet
|
|
|
+ * - `ng-dirty`: the control has been interacted with
|
|
|
+ * - `ng-touched`: the control has been blurred
|
|
|
+ * - `ng-untouched`: the control hasn't been blurred
|
|
|
+ * - `ng-pending`: any `$asyncValidators` are unfulfilled
|
|
|
+ * - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
|
|
|
+ * by the {@link ngModel.NgModelController#$isEmpty} method
|
|
|
+ * - `ng-not-empty`: the view contains a non-empty value
|
|
|
+ *
|
|
|
+ * Keep in mind that ngAnimate can detect each of these classes when added and removed.
|
|
|
+ *
|
|
|
+ * ## Animation Hooks
|
|
|
+ *
|
|
|
+ * Animations within models are triggered when any of the associated CSS classes are added and removed
|
|
|
+ * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
|
|
|
+ * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
|
|
|
+ * The animations that are triggered within ngModel are similar to how they work in ngClass and
|
|
|
+ * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
|
|
|
+ *
|
|
|
+ * The following example shows a simple way to utilize CSS transitions to style an input element
|
|
|
+ * that has been rendered as invalid after it has been validated:
|
|
|
+ *
|
|
|
+ * <pre>
|
|
|
+ * //be sure to include ngAnimate as a module to hook into more
|
|
|
+ * //advanced animations
|
|
|
+ * .my-input {
|
|
|
+ * transition:0.5s linear all;
|
|
|
+ * background: white;
|
|
|
+ * }
|
|
|
+ * .my-input.ng-invalid {
|
|
|
+ * background: red;
|
|
|
+ * color:white;
|
|
|
+ * }
|
|
|
+ * </pre>
|
|
|
+ *
|
|
|
+ * @example
|
|
|
+ * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample" name="ng-model">
|
|
|
+ <file name="index.html">
|
|
|
+ <script>
|
|
|
+ angular.module('inputExample', [])
|
|
|
+ .controller('ExampleController', ['$scope', function($scope) {
|
|
|
+ $scope.val = '1';
|
|
|
+ }]);
|
|
|
+ </script>
|
|
|
+ <style>
|
|
|
+ .my-input {
|
|
|
+ transition:all linear 0.5s;
|
|
|
+ background: transparent;
|
|
|
+ }
|
|
|
+ .my-input.ng-invalid {
|
|
|
+ color:white;
|
|
|
+ background: red;
|
|
|
+ }
|
|
|
+ </style>
|
|
|
+ <p id="inputDescription">
|
|
|
+ Update input to see transitions when valid/invalid.
|
|
|
+ Integer is a valid value.
|
|
|
+ </p>
|
|
|
+ <form name="testForm" ng-controller="ExampleController">
|
|
|
+ <input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input"
|
|
|
+ aria-describedby="inputDescription" />

|
|
|
+ * ## Binding to a getter/setter
|
|
|
+ *
|
|
|
+ * Sometimes it's helpful to bind `ngModel` to a getter/setter function. A getter/setter is a
|
|
|
+ * function that returns a representation of the model when called with zero arguments, and sets
|
|
|
+ * the internal state of a model when called with an argument. It's sometimes useful to use this
|
|
|
+ * for models that have an internal representation that's different from what the model exposes
|
|
|
+ * to the view.
|
|
|
+ *
|
|
|
+ * <div class="alert alert-success">
|
|
|
+ * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
|
|
|
+ * frequently than other parts of your code.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
|
|
|
+ * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
|
|
|
+ * a `<form>`, which will enable this behavior for all `<input>`s within it. See
|
|
|
+ * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
|
|
|
+ *
|
|
|
+ * The following example shows how to use `ngModel` with a getter/setter:
|
|
|
+ *
|
|
|
+ * @example
|
|
|
+ * <example name="ngModel-getter-setter" module="getterSetterExample">
|
|
|
+ <file name="index.html">
|
|
|
+ <div ng-controller="ExampleController">
|
|

|
|
+ <label>Name:
|
|
|
+ <input type="text" name="userName"
|
|
|
+ ng-model="user.name"
|
|
|
+ ng-model-options="{ getterSetter: true }" />
|
|
|
+ </label>
|
|
|
+ </form>
|
|
|
+ <pre>user.name = <span ng-bind="user.name()"></span></pre>
|
|
|
+ </div>
|
|
|
+ </file>
|
|
|
+ <file name="app.js">
|
|
|
+ angular.module('getterSetterExample', [])
|
|
|
+ .controller('ExampleController', ['$scope', function($scope) {
|
|
|
+ var _name = 'Brian';
|
|
|
+ $scope.user = {
|
|
|
+ name: function(newName) {
|
|
|
+ // Note that newName can be undefined for two reasons:
|
|
|
+ // 1. Because it is called as a getter and thus called with no arguments
|
|
|
+ // 2. Because the property should actually be set to undefined. This happens e.g. if the
|
|
|
+ // input is invalid
|
|
|
+ return arguments.length ? (_name = newName) : _name;
|
|
|
+ }
|

|
|
|
+ * @description
|
|
|
+ * This directive allows you to modify the behaviour of {@link ngModel} directives within your
|
|
|
+ * application. You can specify an `ngModelOptions` directive on any element. All {@link ngModel}
|
|
|
+ * directives will use the options of their nearest `ngModelOptions` ancestor.
|
|
|
+ *
|
|
|
+ * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as
|
|
|
+ * an Angular expression. This expression should evaluate to an object, whose properties contain
|
|
|
+ * the settings. For example: `<div "ng-model-options"="{ debounce: 100 }"`.
|
|
|
+ *
|
|
|
+ * ## Inheriting Options
|
|
|
+ *
|
|
|
+ * You can specify that an `ngModelOptions` setting should be inherited from a parent `ngModelOptions`
|
|
|
+ * directive by giving it the value of `"$inherit"`.
|
|
|
+ * Then it will inherit that setting from the first `ngModelOptions` directive found by traversing up the
|
|
|
+ * DOM tree. If there is no ancestor element containing an `ngModelOptions` directive then default settings
|
|
|
+ * will be used.
|
|
|
+ *
|
|
|
+ * For example given the following fragment of HTML
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ```html
|
|
|
+ * <div ng-model-options="{ allowInvalid: true, debounce: 200 }">
|
|
|
+ * <form ng-model-options="{ updateOn: 'blur', allowInvalid: '$inherit' }">
|
|
|
+ * <input ng-model-options="{ updateOn: 'default', allowInvalid: '$inherit' }" />
|
|
|
+ * </form>
|
|
|
+ * </div>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * the `input` element will have the following settings
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * { allowInvalid: true, updateOn: 'default', debounce: 0 }
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * Notice that the `debounce` setting was not inherited and used the default value instead.
|
|
|
+ *
|
|
|
+ * You can specify that all undefined settings are automatically inherited from an ancestor by
|
|
|
+ * including a property with key of `"*"` and value of `"$inherit"`.
|
|
|
+ *
|
|
|
+ * For example given the following fragment of HTML
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ```html
|
|
|
+ * <div ng-model-options="{ allowInvalid: true, debounce: 200 }">
|
|
|
+ * <form ng-model-options="{ updateOn: 'blur', "*": '$inherit' }">
|
|
|
+ * <input ng-model-options="{ updateOn: 'default', "*": '$inherit' }" />
|
|
|
+ * </form>
|
|
|
+ * </div>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * the `input` element will have the following settings
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * { allowInvalid: true, updateOn: 'default', debounce: 200 }
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * Notice that the `debounce` setting now inherits the value from the outer `<div>` element.
|
|
|
+ *
|
|
|
+ * If you are creating a reusable component then you should be careful when using `"*": "$inherit"`
|
|
|
+ * since you may inadvertently inherit a setting in the future that changes the behavior of your component.

|
|
|
+ * ## Triggering and debouncing model updates
|
|
|
+ *
|
|
|
+ * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will
|
|
|
+ * trigger a model update and/or a debouncing delay so that the actual update only takes place when
|
|
|
+ * a timer expires; this timer will be reset after another change takes place.
|
|
|
+ *
|
|
|
+ * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
|
|
|
+ * be different from the value in the actual model. This means that if you update the model you
|
|
|
+ * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in
|
|
|
+ * order to make sure it is synchronized with the model and that any debounced action is canceled.
|
|
|
+ *
|
|
|
+ * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue}
|
|
|
+ * method is by making sure the input is placed inside a form that has a `name` attribute. This is
|
|
|
+ * important because `form` controllers are published to the related scope under the name in their
|
|
|
+ * `name` attribute.
|
|
|
+ *
|
|
|
+ * Any pending changes will take place immediately when an enclosing form is submitted via the
|
|
|
+ * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
|
|
|
+ * to have access to the updated model.
|
|
|
+ *
|
|
|
+ * The following example shows how to override immediate updates. Changes on the inputs within the
|
|
|
+ * form will update the model only when the control loses focus (blur event). If `escape` key is
|
|
|
+ * pressed while the input field is focused, the value is reset to the value in the current model.

|
|
|
+ * ## Model updates and validation
|
|
|
+ *
|
|
|
+ * The default behaviour in `ngModel` is that the model value is set to `undefined` when the
|
|
|
+ * validation determines that the value is invalid. By setting the `allowInvalid` property to true,
|
|
|
+ * the model will still be updated even if the value is invalid.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ## Connecting to the scope
|
|
|
+ *
|
|
|
+ * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression
|
|
|
+ * on the scope refers to a "getter/setter" function rather than the value itself.
|
|
|
+ *
|
|
|
+ * The following example shows how to bind to getter/setters:
|
|
|
+ *
|
|
|
+ * <example name="ngModelOptions-directive-getter-setter" module="getterSetterExample">
|
|
|
+ * <file name="index.html">
|
|
|
+ * <div ng-controller="ExampleController">
|
|
|
+ * <form name="userForm">

|
|

|
+ * ng-model-options="{ getterSetter: true }" />
|
|
|
+ * </label>
|
|
|
+ * </form>
|
|
|
+ * <pre>user.name = <span ng-bind="user.name()"></span></pre>
|
|
|
+ * </div>
|
|
|
+ * </file>
|
|
|
+ * <file name="app.js">
|
|
|
+ * angular.module('getterSetterExample', [])
|
|
|
+ * .controller('ExampleController', ['$scope', function($scope) {
|
|
|
+ * var _name = 'Brian';
|
|
|
+ * $scope.user = {
|
|
|
+ * name: function(newName) {
|
|
|
+ * return angular.isDefined(newName) ? (_name = newName) : _name;
|
|
|
+ * }
|
|

|

|
+ *
|
|
|
+ *
|
|
|
+ * ## Specifying timezones
|
|
|
+ *
|
|
|
+ * You can specify the timezone that date/time input directives expect by providing its name in the
|
|
|
+ * `timezone` property.
|
|
|
+ *
|
|
|
+ * @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and
|
|
|
+ * and its descendents. Valid keys are:
|
|
|
+ * - `updateOn`: string specifying which event should the input be bound to. You can set several
|
|
|
+ * events using an space delimited list. There is a special event called `default` that
|
|
|
+ * matches the default events belonging to the control.
|
|
|
+ * - `debounce`: integer value which contains the debounce model update value in milliseconds. A
|
|
|
+ * value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
|
|
|
+ * custom value for each event. For example:
|
|
|
+ * ```
|
|
|
+ * ng-model-options="{
|
|
|
+ * updateOn: 'default blur',
|
|
|
+ * debounce: { 'default': 500, 'blur': 0 }
|
|
|
+ * }"
|
|
|
+ * ```
|
|
|
+ * - `allowInvalid`: boolean value which indicates that the model can be set with values that did
|
|
|
+ * not validate correctly instead of the default behavior of setting the model to undefined.
|
|
|
+ * - `getterSetter`: boolean value which determines whether or not to treat functions bound to
|
|
|
+ * `ngModel` as getters/setters.
|
|
|
+ * - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
|
|
|
+ * `<input type="date" />`, `<input type="time" />`, ... . It understands UTC/GMT and the
|
|
|
+ * continental US time zone abbreviations, but for general use, use a time zone offset, for
|
|
|
+ * example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
|
|
|
+ * If not specified, the timezone of the browser will be used.

|

|
|
|
+ * The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
|
|
|
+ * elements for the `<select>` element using the array or object obtained by evaluating the
|
|
|
+ * `ngOptions` comprehension expression.
|
|
|
+ *
|
|
|
+ * In many cases, {@link ng.directive:ngRepeat ngRepeat} can be used on `<option>` elements instead of
|
|
|
+ * `ngOptions` to achieve a similar result. However, `ngOptions` provides some benefits:
|
|
|
+ * - more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
|
|
|
+ * comprehension expression
|
|
|
+ * - reduced memory consumption by not creating a new scope for each repeated instance
|
|
|
+ * - increased render speed by creating the options in a documentFragment instead of individually
|
|
|
+ *
|
|
|
+ * When an item in the `<select>` menu is selected, the array element or object property
|
|
|
+ * represented by the selected option will be bound to the model identified by the `ngModel`
|
|
|
+ * directive.
|
|
|
+ *
|
|
|
+ * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
|
|
|
+ * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
|
|
|
+ * option. See example below for demonstration.
|
|
|
+ *
|
|
|
+ * ## Complex Models (objects or collections)
|
|
|
+ *
|
|
|
+ * By default, `ngModel` watches the model by reference, not value. This is important to know when
|
|
|
+ * binding the select to a model that is an object or a collection.
|
|
|
+ *
|
|
|
+ * One issue occurs if you want to preselect an option. For example, if you set
|
|
|
+ * the model to an object that is equal to an object in your collection, `ngOptions` won't be able to set the selection,
|
|
|
+ * because the objects are not identical. So by default, you should always reference the item in your collection
|
|
|
+ * for preselections, e.g.: `$scope.selected = $scope.collection[3]`.
|
|
|
+ *
|
|
|
+ * Another solution is to use a `track by` clause, because then `ngOptions` will track the identity
|
|
|
+ * of the item not by reference, but by the result of the `track by` expression. For example, if your
|
|
|
+ * collection items have an id property, you would `track by item.id`.
|
|
|
+ *
|
|
|
+ * A different issue with objects or collections is that ngModel won't detect if an object property or
|
|
|
+ * a collection item changes. For that reason, `ngOptions` additionally watches the model using
|
|
|
+ * `$watchCollection`, when the expression contains a `track by` clause or the the select has the `multiple` attribute.
|
|
|
+ * This allows ngOptions to trigger a re-rendering of the options even if the actual object/collection
|
|
|
+ * has not changed identity, but only a property on the object or an item in the collection changes.
|
|
|
+ *
|
|
|
+ * Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection
|
|
|
+ * if the model is an array). This means that changing a property deeper than the first level inside the
|
|
|
+ * object/collection will not trigger a re-rendering.
|
|
|
+ *
|
|
|
+ * ## `select` **`as`**
|
|
|
+ *
|
|
|
+ * Using `select` **`as`** will bind the result of the `select` expression to the model, but
|
|
|
+ * the value of the `<select>` and `<option>` html elements will be either the index (for array data sources)
|
|
|
+ * or property name (for object data sources) of the value within the collection. If a **`track by`** expression
|
|
|
+ * is used, the result of that expression will be set as the value of the `option` and `select` elements.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * ### `select` **`as`** and **`track by`**
|
|
|
+ *
|
|
|
+ * <div class="alert alert-warning">
|
|
|
+ * Be careful when using `select` **`as`** and **`track by`** in the same expression.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * Given this array of items on the $scope:
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * $scope.items = [{
|
|
|
+ * id: 1,
|
|
|
+ * label: 'aLabel',
|
|
|
+ * subItem: { name: 'aSubItem' }
|
|
|
+ * }, {
|
|
|
+ * id: 2,
|
|
|
+ * label: 'bLabel',
|
|
|
+ * subItem: { name: 'bSubItem' }
|
|
|
+ * }];
|
|
|
+ * ```
|
|
|

|
|

|

+ * <select ng-options="item as item.label for item in items track by item.id" ng-model="selected"></select>
|
|
|
+ * ```
|
|
|
+ * ```js
|
|
|
+ * $scope.selected = $scope.items[0];
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * but this will not work:
|
|
|
+ *
|
|
|
+ * ```html
|
|
|
+ * <select ng-options="item.subItem as item.label for item in items track by item.id" ng-model="selected"></select>
|
|
|
+ * ```
|
|
|
+ * ```js
|
|
|
+ * $scope.selected = $scope.items[0].subItem;
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * In both examples, the **`track by`** expression is applied successfully to each `item` in the
|
|
|
+ * `items` array. Because the selected option has been set programmatically in the controller, the
|
|
|
+ * **`track by`** expression is also applied to the `ngModel` value. In the first example, the
|
|
|
+ * `ngModel` value is `items[0]` and the **`track by`** expression evaluates to `items[0].id` with
|
|
|
+ * no issue. In the second example, the `ngModel` value is `items[0].subItem` and the **`track by`**
|
|
|
+ * expression evaluates to `items[0].subItem.id` (which is undefined). As a result, the model value
|
|
|
+ * is not matched against any `<option>` and the `<select>` appears as having no selected value.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * @param {string} ngModel Assignable angular expression to data-bind to.
|
|
|
+ * @param {string=} name Property name of the form under which the control is published.
|
|
|
+ * @param {string=} required The control is considered valid only if value is entered.
|
|
|
+ * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
|
|
|
+ * the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
|
|
|
+ * `required` when you want to data-bind to the `required` attribute.
|
|
|
+ * @param {comprehension_expression=} ngOptions in one of the following forms:
|
|
|
+ *
|
|
|
+ * * for array data sources:
|
|
|
+ * * `label` **`for`** `value` **`in`** `array`

|
|
|
+ * * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
|
|
|
+ * * `label` **`for`** `value` **`in`** `array` | orderBy:`orderexpr` **`track by`** `trackexpr`
|
|
|
+ * (for including a filter with `track by`)
|
|
|
+ * * for object data sources:
|
|
|
+ * * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
|
|
|
+ * * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
|

|
|
|
+ * * `label` **`disable when`** `disable` **`for (`**`key`**`,`** `value`**`) in`** `object`
|
|
|
+ * * `select` **`as`** `label` **`group by`** `group`
|
|
|
+ * **`for` `(`**`key`**`,`** `value`**`) in`** `object`
|
|
|
+ * * `select` **`as`** `label` **`disable when`** `disable`
|
|
|

|
|
|
+ *
|
|
|
+ * Where:
|
|
|
+ *
|
|
|
+ * * `array` / `object`: an expression which evaluates to an array / object to iterate over.
|
|
|
+ * * `value`: local variable which will refer to each item in the `array` or each property value
|
|
|
+ * of `object` during iteration.
|
|
|
+ * * `key`: local variable which will refer to a property name in `object` during iteration.
|
|
|
+ * * `label`: The result of this expression will be the label for `<option>` element. The
|
|
|
+ * `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
|
|
|
+ * * `select`: The result of this expression will be bound to the model of the parent `<select>`
|
|
|
+ * element. If not specified, `select` expression will default to `value`.
|
|
|
+ * * `group`: The result of this expression will be used to group options using the `<optgroup>`
|
|
|
+ * DOM element.
|
|
|
+ * * `disable`: The result of this expression will be used to disable the rendered `<option>`
|
|
|
+ * element. Return `true` to disable.
|
|
|
+ * * `trackexpr`: Used when working with an array of objects. The result of this expression will be
|
|
|
+ * used to identify the objects in the array. The `trackexpr` will most likely refer to the
|
|
|
+ * `value` variable (e.g. `value.propertyName`). With this the selection is preserved
|
|
|
+ * even when the options are recreated (e.g. reloaded from the server).

|

|
|

|
|
|
+ *
|
|
|
+ * @description
|
|
|
+ * `ngPluralize` is a directive that displays messages according to en-US localization rules.
|
|
|
+ * These rules are bundled with angular.js, but can be overridden
|
|
|
+ * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
|
|
|
+ * by specifying the mappings between
|
|
|
+ * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
|
|
|
+ * and the strings to be displayed.
|
|
|
+ *
|
|
|
+ * # Plural categories and explicit number rules
|
|
|
+ * There are two
|
|
|
+ * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
|
|
|
+ * in Angular's default en-US locale: "one" and "other".
|
|
|
+ *
|
|
|
+ * While a plural category may match many numbers (for example, in en-US locale, "other" can match
|
|
|
+ * any number that is not 1), an explicit number rule can only match one number. For example, the
|
|
|
+ * explicit number rule for "3" matches the number 3. There are examples of plural categories
|
|
|
+ * and explicit number rules throughout the rest of this documentation.
|
|
|
+ *
|
|
|
+ * # Configuring ngPluralize
|
|
|
+ * You configure ngPluralize by providing 2 attributes: `count` and `when`.
|
|
|
+ * You can also provide an optional attribute, `offset`.
|
|
|
+ *
|
|
|
+ * The value of the `count` attribute can be either a string or an {@link guide/expression
|
|
|
+ * Angular expression}; these are evaluated on the current scope for its bound value.
|
|
|
+ *
|
|
|
+ * The `when` attribute specifies the mappings between plural categories and the actual
|
|
|
+ * string to be displayed. The value of the attribute should be a JSON object.
|
|
|
+ *
|
|
|
+ * The following example shows how to configure ngPluralize:
|
|
|
+ *
|
|
|
+ * ```html
|
|
|
+ * <ng-pluralize count="personCount"
|
|
|
+ when="{'0': 'Nobody is viewing.',
|
|
|
+ * 'one': '1 person is viewing.',
|
|
|
+ * 'other': '{} people are viewing.'}">
|
|
|
+ * </ng-pluralize>
|
|
|
+ *```
|
|
|
+ *
|
|
|
+ * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
|
|
|
+ * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
|
|
|
+ * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
|
|
|
+ * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
|
|
|
+ * show "a dozen people are viewing".
|
|
|
+ *
|
|
|
+ * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
|
|
|
+ * into pluralized strings. In the previous example, Angular will replace `{}` with
|
|
|
+ * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
|
|
|
+ * for <span ng-non-bindable>{{numberExpression}}</span>.
|
|
|
+ *
|
|
|
+ * If no rule is defined for a category, then an empty string is displayed and a warning is generated.
|
|
|
+ * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`.
|
|
|
+ *
|
|
|
+ * # Configuring ngPluralize with offset
|
|
|
+ * The `offset` attribute allows further customization of pluralized text, which can result in
|
|
|
+ * a better user experience. For example, instead of the message "4 people are viewing this document",
|
|
|
+ * you might display "John, Kate and 2 others are viewing this document".
|
|
|
+ * The offset attribute allows you to offset a number by any desired value.
|
|
|
+ * Let's take a look at an example:
|
|
|
+ *
|
|
|
+ * ```html
|
|
|
+ * <ng-pluralize count="personCount" offset=2
|
|
|
+ * when="{'0': 'Nobody is viewing.',
|
|
|
+ * '1': '{{person1}} is viewing.',
|
|
|
+ * '2': '{{person1}} and {{person2}} are viewing.',
|
|
|
+ * 'one': '{{person1}}, {{person2}} and one other person are viewing.',
|
|
|
+ * 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
|
|
|
+ * </ng-pluralize>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * Notice that we are still using two plural categories(one, other), but we added
|
|
|
+ * three explicit number rules 0, 1 and 2.
|
|
|
+ * When one person, perhaps John, views the document, "John is viewing" will be shown.
|
|
|
+ * When three people view the document, no explicit number rule is found, so
|
|
|
+ * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
|
|
|
+ * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing"
|
|
|
+ * is shown.
|
|
|
+ *
|
|
|
+ * Note that when you specify offsets, you must provide explicit number rules for
|
|
|
+ * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
|
|
|
+ * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
|
|
|
+ * plural categories "one" and "other".
|
|
|
+ *
|
|
|
+ * @param {string|expression} count The variable to be bound to.
|
|
|
+ * @param {string} when The mapping between plural category to its corresponding strings.
|
|
|
+ * @param {number=} offset Offset to deduct from the total number.
|
|
|
+ *

|
|
|

|
|
|

|

|
|
|
+ * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
|
|
|
+ * | `$last` | {@type boolean} | true if the repeated element is last in the iterator. |
|
|
|
+ * | `$even` | {@type boolean} | true if the iterator position `$index` is even (otherwise false). |

|
|
|
+ * # Iterating over object properties
|
|
|
+ *
|
|
|
+ * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
|
|
|
+ * syntax:
|
|
|
+ *
|
|
|
+ * ```js
|
|
|
+ * <div ng-repeat="(key, value) in myObj"> ... </div>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * However, there are a few limitations compared to array iteration:
|
|
|
+ *
|
|
|
+ * - The JavaScript specification does not define the order of keys
|
|
|
+ * returned for an object, so Angular relies on the order returned by the browser
|
|
|
+ * when running `for key in myObj`. Browsers generally follow the strategy of providing
|
|
|
+ * keys in the order in which they were defined, although there are exceptions when keys are deleted
|
|
|
+ * and reinstated. See the
|
|
|
+ * [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).
|
|
|
+ *
|
|
|
+ * - `ngRepeat` will silently *ignore* object keys starting with `$`, because
|
|
|
+ * it's a prefix used by Angular for public (`$`) and private (`$$`) properties.
|
|
|
+ *
|
|
|
+ * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with
|
|
|
+ * objects, and will throw an error if used with one.
|
|
|
+ *
|
|
|
+ * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array
|
|
|
+ * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could
|
|
|
+ * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
|
|
|
+ * or implement a `$watch` on the object yourself.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * # Tracking and Duplicates
|
|
|
+ *
|
|
|
+ * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in
|
|
|
+ * the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM:
|
|
|
+ *
|
|
|
+ * * When an item is added, a new instance of the template is added to the DOM.
|
|
|
+ * * When an item is removed, its template instance is removed from the DOM.
|
|
|
+ * * When items are reordered, their respective templates are reordered in the DOM.
|
|
|
+ *
|
|
|
+ * To minimize creation of DOM elements, `ngRepeat` uses a function
|
|
|
+ * to "keep track" of all items in the collection and their corresponding DOM elements.
|
|
|
+ * For example, if an item is added to the collection, `ngRepeat` will know that all other items
|
|
|
+ * already have DOM elements, and will not re-render them.
|
|
|
+ *
|
|
|
+ * The default tracking function (which tracks items by their identity) does not allow
|
|
|
+ * duplicate items in arrays. This is because when there are duplicates, it is not possible
|
|
|
+ * to maintain a one-to-one mapping between collection items and DOM elements.
|
|
|
+ *
|
|
|
+ * If you do need to repeat duplicate items, you can substitute the default tracking behavior
|
|
|
+ * with your own using the `track by` expression.
|
|
|
+ *
|
|
|
+ * For example, you may track items by the index of each item in the collection, using the
|
|
|
+ * special scope property `$index`:
|
|
|
+ * ```html
|
|
|
+ * <div ng-repeat="n in [42, 42, 43, 43] track by $index">
|
|
|
+ * {{n}}
|
|
|
+ * </div>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * You may also use arbitrary expressions in `track by`, including references to custom functions
|
|
|
+ * on the scope:
|
|
|
+ * ```html
|
|
|
+ * <div ng-repeat="n in [42, 42, 43, 43] track by myTrackingFunction(n)">
|
|
|
+ * {{n}}
|
|
|
+ * </div>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * <div class="alert alert-success">
|
|
|
+ * If you are working with objects that have a unique identifier property, you should track
|
|
|
+ * by this identifier instead of the object instance. Should you reload your data later, `ngRepeat`
|
|
|
+ * will not have to rebuild the DOM elements for items it has already rendered, even if the
|
|
|
+ * JavaScript objects in the collection have been substituted for new ones. For large collections,
|
|
|
+ * this significantly improves rendering performance. If you don't have a unique identifier,
|
|
|
+ * `track by $index` can also provide a performance boost.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * ```html
|
|
|
+ * <div ng-repeat="model in collection track by model.id">
|
|
|
+ * {{model.name}}
|
|
|
+ * </div>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * <br />
|
|
|
+ * <div class="alert alert-warning">
|
|
|
+ * Avoid using `track by $index` when the repeated template contains
|
|
|
+ * {@link guide/expression#one-time-binding one-time bindings}. In such cases, the `nth` DOM
|
|
|
+ * element will always be matched with the `nth` item of the array, so the bindings on that element
|
|
|
+ * will not be updated even when the corresponding item changes, essentially causing the view to get
|
|
|
+ * out-of-sync with the underlying data.
|
|
|
+ * </div>
|
|
|
+ *
|
|
|
+ * When no `track by` expression is provided, it is equivalent to tracking by the built-in
|
|
|
+ * `$id` function, which tracks items by their identity:
|
|
|
+ * ```html
|
|
|
+ * <div ng-repeat="obj in collection track by $id(obj)">

|
|
+ * {{obj.prop}}
|
|
|
+ * </div>
|

|
+ * ```

|
|
+ *
|
|
|
+ * <br />
|
|
|
+ * <div class="alert alert-warning">
|
|
|
+ * **Note:** `track by` must always be the last expression:
|
|
|
+ * </div>
|
|
|

|
|
|
+ * <div ng-repeat="model in collection | orderBy: 'id' as filtered_result track by model.id">

|
|
|
+ * # Special repeat start and end points
|
|
|
+ * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
|
|
|
+ * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
|
|
|
+ * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
|
|
|
+ * up to and including the ending HTML tag where **ng-repeat-end** is placed.
|
|
|
+ *
|
|
|
+ * The example below makes use of this feature:
|
|
|
+ * ```html
|
|
|
+ * <header ng-repeat-start="item in items">
|
|
|
+ * Header {{ item }}
|
|
|
+ * </header>
|
|
|
+ * <div class="body">
|
|
|
+ * Body {{ item }}
|
|
|
+ * </div>
|
|
|
+ * <footer ng-repeat-end>
|
|
|
+ * Footer {{ item }}
|
|
|
+ * </footer>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
|
|
|
+ * ```html
|
|
|
+ * <header>
|
|
|
+ * Header A
|
|
|
+ * </header>
|
|
|
+ * <div class="body">
|
|
|
+ * Body A
|
|
|
+ * </div>
|
|
|
+ * <footer>
|
|
|
+ * Footer A
|
|
|
+ * </footer>
|
|
|
+ * <header>
|
|
|
+ * Header B
|
|
|
+ * </header>
|
|
|
+ * <div class="body">
|
|
|
+ * Body B
|
|
|
+ * </div>
|
|
|
+ * <footer>
|
|
|
+ * Footer B
|
|
|
+ * </footer>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
|
|
|
+ * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).

|

|

|
|
|
+ * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
|
|
|
+ * formats are currently supported:
|
|
|
+ *
|
|
|
+ * * `variable in expression` – where variable is the user defined loop variable and `expression`
|
|
|
+ * is a scope expression giving the collection to enumerate.
|
|
|
+ *
|
|
|
+ * For example: `album in artist.albums`.
|
|
|
+ *
|
|
|
+ * * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
|
|
|
+ * and `expression` is the scope expression giving the collection to enumerate.
|
|
|
+ *
|
|
|
+ * For example: `(name, age) in {'adam':10, 'amalie':12}`.
|
|
|
+ *
|
|
|
+ * * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
|
|
|
+ * which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
|
|
|
+ * is specified, ng-repeat associates elements by identity. It is an error to have
|
|
|
+ * more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
|
|
|
+ * mapped to the same DOM element, which is not possible.)
|
|
|
+ *
|
|
|
+ * Note that the tracking expression must come last, after any filters, and the alias expression.
|
|
|
+ *
|
|
|
+ * For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements
|
|
|
+ * will be associated by item identity in the array.
|
|
|
+ *
|
|
|
+ * For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
|
|
|
+ * `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
|
|
|
+ * with the corresponding item in the array by identity. Moving the same object in array would move the DOM
|
|
|
+ * element in the same way in the DOM.
|
|
|
+ *
|
|
|
+ * For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
|
|
|
+ * case the object identity does not matter. Two objects are considered equivalent as long as their `id`
|
|
|
+ * property is same.
|
|
|
+ *
|
|
|
+ * For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
|
|
|
+ * to items in conjunction with a tracking expression.
|
|
|
+ *
|
|
|
+ * * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
|
|
|
+ * intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
|
|
|
+ * when a filter is active on the repeater, but the filtered result set is empty.
|
|
|
+ *
|
|
|
+ * For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
|
|
|
+ * the items have been processed through the filter.
|
|
|
+ *
|
|
|
+ * Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end
|
|
|
+ * (and not as operator, inside an expression).
|
|
|
+ *
|
|
|
+ * For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` .
|
|
|
+ *
|
|
|
+ * @example
|
|
|
+ * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed
|
|
|
+ * results by name or by age. New (entering) and removed (leaving) items are animated.

|
|
|
+ * @ngdoc directive
|
|
|
+ * @name ngShow
|
|
|
+ * @multiElement
|
|
|
+ *
|
|
|
+ * @description
|
|
|
+ * The `ngShow` directive shows or hides the given HTML element based on the expression provided to
|
|
|
+ * the `ngShow` attribute.
|
|
|
+ *
|
|
|
+ * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
|
|
|
+ * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
|
|
|
+ * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
|
|
|
+ * {@link ng.directive:ngCsp ngCsp}).
|
|
|
+ *
|
|
|
+ * ```html
|
|
|
+ * <!-- when $scope.myValue is truthy (element is visible) -->
|
|
|
+ * <div ng-show="myValue"></div>
|
|
|
+ *
|
|
|
+ * <!-- when $scope.myValue is falsy (element is hidden) -->
|
|
|
+ * <div ng-show="myValue" class="ng-hide"></div>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added
|
|
|
+ * to the class attribute on the element causing it to become hidden. When truthy, the `.ng-hide`
|
|
|
+ * CSS class is removed from the element causing the element not to appear hidden.
|
|
|
+ *
|
|
|
+ * ## Why is `!important` used?
|
|
|
+ *
|
|
|
+ * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
|
|
|
+ * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
|
|
|
+ * simple as changing the display style on a HTML list item would make hidden elements appear
|
|
|
+ * visible. This also becomes a bigger issue when dealing with CSS frameworks.
|
|
|
+ *
|
|
|
+ * By using `!important`, the show and hide behavior will work as expected despite any clash between
|
|
|
+ * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
|
|
|
+ * developer chooses to override the styling to change how to hide an element then it is just a
|
|
|
+ * matter of using `!important` in their own CSS code.
|
|
|
+ *
|
|
|
+ * ### Overriding `.ng-hide`
|
|
|
+ *
|
|
|
+ * By default, the `.ng-hide` class will style the element with `display: none !important`. If you
|
|
|
+ * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
|
|
|
+ * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
|
|
|
+ * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
|
|
|
+ *
|
|
|
+ * ```css
|
|
|
+ * .ng-hide:not(.ng-hide-animate) {
|
|
|
+ * /* These are just alternative ways of hiding an element */
|
|
|
+ * display: block!important;
|
|
|
+ * position: absolute;
|
|
|
+ * top: -9999px;
|
|
|
+ * left: -9999px;
|
|
|
+ * }
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * By default you don't need to override anything in CSS and the animations will work around the
|
|
|
+ * display style.
|
|
|
+ *
|
|
|
+ * ## A note about animations with `ngShow`
|
|
|
+ *
|
|
|
+ * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
|
|
|
+ * directive expression is true and false. This system works like the animation system present with
|
|
|
+ * `ngClass` except that you must also include the `!important` flag to override the display
|
|
|
+ * property so that the elements are not actually hidden during the animation.
|
|
|
+ *
|
|
|
+ * ```css
|
|
|

|

|
|
|
+ * @multiElement
|
|
|
+ *
|
|
|
+ * @description
|
|
|
+ * The `ngHide` directive shows or hides the given HTML element based on the expression provided to
|
|
|
+ * the `ngHide` attribute.
|
|
|
+ *
|
|
|
+ * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
|
|
|
+ * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
|
|
|
+ * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
|
|
|
+ * {@link ng.directive:ngCsp ngCsp}).
|
|
|
+ *
|
|
|
+ * ```html
|
|
|
+ * <!-- when $scope.myValue is truthy (element is hidden) -->
|
|
|
+ * <div ng-hide="myValue" class="ng-hide"></div>
|
|
|
+ *
|
|
|
+ * <!-- when $scope.myValue is falsy (element is visible) -->
|
|
|
+ * <div ng-hide="myValue"></div>
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * When the `ngHide` expression evaluates to a truthy value then the `.ng-hide` CSS class is added
|
|
|
+ * to the class attribute on the element causing it to become hidden. When falsy, the `.ng-hide`
|
|
|
+ * CSS class is removed from the element causing the element not to appear hidden.
|
|
|
+ *
|
|
|
+ * ## Why is `!important` used?
|
|
|
+ *
|
|
|
+ * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
|
|
|
+ * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
|
|
|
+ * simple as changing the display style on a HTML list item would make hidden elements appear
|
|
|
+ * visible. This also becomes a bigger issue when dealing with CSS frameworks.
|
|
|
+ *
|
|
|
+ * By using `!important`, the show and hide behavior will work as expected despite any clash between
|
|
|
+ * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
|
|
|
+ * developer chooses to override the styling to change how to hide an element then it is just a
|
|
|
+ * matter of using `!important` in their own CSS code.
|
|
|
+ *
|
|
|
+ * ### Overriding `.ng-hide`
|
|
|
+ *
|
|
|
+ * By default, the `.ng-hide` class will style the element with `display: none !important`. If you
|
|
|
+ * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
|
|
|
+ * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
|
|
|
+ * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
|
|
|
+ *
|
|
|
+ * ```css
|
|
|
+ * .ng-hide:not(.ng-hide-animate) {
|
|
|
+ * /* These are just alternative ways of hiding an element */
|
|
|
+ * display: block!important;
|
|
|
+ * position: absolute;
|
|
|
+ * top: -9999px;
|
|
|
+ * left: -9999px;
|
|
|
+ * }
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * By default you don't need to override in CSS anything and the animations will work around the
|
|
|
+ * display style.
|
|
|
+ *
|
|
|
+ * ## A note about animations with `ngHide`
|
|
|
+ *
|
|
|
+ * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
|
|
|
+ * directive expression is true and false. This system works like the animation system present with
|
|
|
+ * `ngClass` except that you must also include the `!important` flag to override the display
|
|
|
+ * property so that the elements are not actually hidden during the animation.
|
|
|
+ *
|
|
|
+ * ```css
|
|
|
+ * /* A working example can be found at the bottom of this page. */
|
|
|
+ * .my-element.ng-hide-add, .my-element.ng-hide-remove {
|
|
|
+ * transition: all 0.5s linear;
|
|
|
+ * }
|
|
|
+ *
|
|
|
+ * .my-element.ng-hide-add { ... }
|
|
|
+ * .my-element.ng-hide-add.ng-hide-add-active { ... }
|
|
|
+ * .my-element.ng-hide-remove { ... }
|
|
|
+ * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
|
|
|
+ * ```
|
|
|
+ *
|
|
|
+ * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property
|
|
|
+ * to block during animation states - ngAnimate will automatically handle the style toggling for you.

|
|
|
+ * @description
|
|
|
+ * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
|
|
|
+ * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
|
|
|
+ * as specified in the template.
|
|
|
+ *
|
|
|
+ * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
|
|
|
+ * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
|
|
|
+ * matches the value obtained from the evaluated expression. In other words, you define a container element
|
|
|
+ * (where you place the directive), place an expression on the **`on="..."` attribute**
|
|
|
+ * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
|
|
|
+ * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
|
|
|
+ * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
|
|
|
+ * attribute is displayed.
|
|
|
+ *
|
|
|
+ * <div class="alert alert-info">
|
|
|
+ * Be aware that the attribute values to match against cannot be expressions. They are interpreted
|
|
|
+ * as literal string values to match against.
|
|
|
+ * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
|
|
|
+ * value of the expression `$scope.someVal`.

|
|
|
+ * @priority 1200
|
|
|
+ * @param {*} ngSwitch|on expression to match against <code>ng-switch-when</code>.
|
|
|
+ * On child elements add:
|
|
|
+ *
|
|
|
+ * * `ngSwitchWhen`: the case statement to match against. If match then this
|
|
|
+ * case will be displayed. If the same match appears multiple times, all the
|
|
|
+ * elements will be displayed. It is possible to associate multiple values to
|
|
|
+ * the same `ngSwitchWhen` by defining the optional attribute
|
|
|
+ * `ngSwitchWhenSeparator`. The separator will be used to split the value of
|
|
|
+ * the `ngSwitchWhen` attribute into multiple tokens, and the element will show
|
|
|
+ * if any of the `ngSwitch` evaluates to any of these tokens.
|
|
|
+ * * `ngSwitchDefault`: the default case when no other case match. If there
|
|
|
+ * are multiple default cases, all of them will be displayed when no other
|
|
|
+ * case match.

|
|
|
+ * @description
|
|
|
+ * Directive that marks the insertion point for the transcluded DOM of the nearest parent directive that uses transclusion.
|
|
|
+ *
|
|
|
+ * You can specify that you want to insert a named transclusion slot, instead of the default slot, by providing the slot name
|
|
|
+ * as the value of the `ng-transclude` or `ng-transclude-slot` attribute.
|
|
|
+ *
|
|
|
+ * If the transcluded content is not empty (i.e. contains one or more DOM nodes, including whitespace text nodes), any existing
|
|
|
+ * content of this element will be removed before the transcluded content is inserted.
|
|
|
+ * If the transcluded content is empty (or only whitespace), the existing content is left intact. This lets you provide fallback
|
|
|
+ * content in the case that no transcluded content is provided.

|
|
+ *
|
|
|
+ * @element ANY
|

+ * @param {string} ngTransclude|ngTranscludeSlot the name of the slot to insert at this point. If this is not provided, is empty
|

+ * or its value is the same as the name of the attribute then the default slot is used.

+ * {@link ngOptions `ngOptions`} directives.
|
|
|
+ *
|
|
|
+ * When an item in the `<select>` menu is selected, the value of the selected option will be bound
|
|
|
+ * to the model identified by the `ngModel` directive. With static or repeated options, this is
|
|
|
+ * the content of the `value` attribute or the textContent of the `<option>`, if the value attribute is missing.
|
|
|
+ * Value and textContent can be interpolated.
|
|
|
+ *
|
|
|
+ * ## Matching model and option values
|
|
|
+ *
|
|
|
+ * In general, the match between the model and an option is evaluated by strictly comparing the model
|
|
|
+ * value against the value of the available options.
|
|
|
+ *
|
|
|
+ * If you are setting the option value with the option's `value` attribute, or textContent, the
|
|
|
+ * value will always be a `string` which means that the model value must also be a string.
|
|
|
+ * Otherwise the `select` directive cannot match them correctly.
|
|
|
+ *
|
|
|
+ * To bind the model to a non-string value, you can use one of the following strategies:
|
|
|
+ * - the {@link ng.ngOptions `ngOptions`} directive
|
|
|
+ * ({@link ng.select#using-select-with-ngoptions-and-setting-a-default-value})
|
|
|
+ * - the {@link ng.ngValue `ngValue`} directive, which allows arbitrary expressions to be
|
|
|
+ * option values ({@link ng.select#using-ngvalue-to-bind-the-model-to-an-array-of-objects Example})
|
|
|
+ * - model $parsers / $formatters to convert the string value
|
|
|
+ * ({@link ng.select#binding-select-to-a-non-string-value-via-ngmodel-parsing-formatting Example})
|
|
|
+ *
|
|
|
+ * If the viewValue of `ngModel` does not match any of the options, then the control
|
|
|
+ * will automatically add an "unknown" option, which it then removes when the mismatch is resolved.
|
|
|
+ *
|
|
|
+ * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
|
|
|
+ * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
|
|
|
+ * option. See example below for demonstration.
|
|
|
+ *
|
|
|
+ * ## Choosing between `ngRepeat` and `ngOptions`
|
|
|
+ *
|
|
|
+ * In many cases, `ngRepeat` can be used on `<option>` elements instead of {@link ng.directive:ngOptions
|
|
|
+ * ngOptions} to achieve a similar result. However, `ngOptions` provides some benefits:
|
|
|
+ * - more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
|
|
|
+ * comprehension expression
|
|
|
+ * - reduced memory consumption by not creating a new scope for each repeated instance
|
|
|
+ * - increased render speed by creating the options in a documentFragment instead of individually
|
|
|
+ *
|
|
|
+ * Specifically, select with repeated options slows down significantly starting at 2000 options in
|
|
|
+ * Chrome and Internet Explorer / Edge.
|
|
|
+ *
|
|
|
+ *
|
|
|
+ * @param {string} ngModel Assignable angular expression to data-bind to.
|
|
|
+ * @param {string=} name Property name of the form under which the control is published.
|
|
|
+ * @param {string=} multiple Allows multiple options to be selected. The selected values will be
|
|
|
+ * bound to the model as an array.
|
|
|
+ * @param {string=} required Sets `required` validation error key if the value is not entered.
|
|
|
+ * @param {string=} ngRequired Adds required attribute and required validation constraint to
|
|
|
+ * the element when the ngRequired expression evaluates to true. Use ngRequired instead of required
|
|
|
+ * when you want to data-bind to the required attribute.
|
|
|
+ * @param {string=} ngChange Angular expression to be executed when selected option(s) changes due to user
|
|
|
+ * interaction with the select element.
|
|
|
+ * @param {string=} ngOptions sets the options that the select is populated with and defines what is
|
|
|
+ * set on the model on selection. See {@link ngOptions `ngOptions`}.

|
|

|
|
|
+ *
|
|
|
+ * ngRequired adds the required {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.
|
|
|
+ * It is most often used for {@link input `input`} and {@link select `select`} controls, but can also be
|
|
|
+ * applied to custom controls.
|
|
|
+ *
|
|
|
+ * The directive sets the `required` attribute on the element if the Angular expression inside
|
|
|
+ * `ngRequired` evaluates to true. A special directive for setting `required` is necessary because we
|
|
|
+ * cannot use interpolation inside `required`. See the {@link guide/interpolation interpolation guide}
|
|
|
+ * for more info.
|
|
|
+ *
|
|
|
+ * The validator will set the `required` error key to true if the `required` attribute is set and
|
|
|
+ * calling {@link ngModel.NgModelController#$isEmpty `NgModelController.$isEmpty`} with the
|
|
|
+ * {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`} returns `true`. For example, the
|
|
|
+ * `$isEmpty()` implementation for `input[text]` checks the length of the `$viewValue`. When developing
|
|
|
+ * custom controls, `$isEmpty()` can be overwritten to account for a $viewValue that is not string-based.

|

+ * The validator sets the `pattern` error key if the {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`}
|

+ * does not match a RegExp which is obtained by evaluating the Angular expression given in the

|
|
+ * `ngPattern` attribute value:
|
|
|
+ * * If the expression evaluates to a RegExp object, then this is used directly.
|
|
|
+ * * If the expression evaluates to a string, then it will be converted to a RegExp after wrapping it
|
