||
* contains redundant trailing slash or is missing one, the route will still match and the
|
||
* `$location.path` will be updated to add or drop the trailing slash to exactly match the
|
||
* route definition.
|
||
*
|
||
* * `path` can contain named groups starting with a colon: e.g. `:name`. All characters up
|
||
* to the next slash are matched and stored in `$routeParams` under the given `name`
|
||
* when the route matches.
|
||
* * `path` can contain named groups starting with a colon and ending with a star:
|
||
* e.g.`:name*`. All characters are eagerly stored in `$routeParams` under the given `name`
|
||
* when the route matches.
|
||
* * `path` can contain optional named groups with a question mark: e.g.`:name?`.
|
||
*
|
||
* For example, routes like `/color/:color/largecode/:largecode*\/edit` will match
|
||
* `/color/brown/largecode/code/with/slashes/edit` and extract:
|
||
*
|
||
* * `color: brown`
|
||
* * `largecode: code/with/slashes`.
|
||
*
|
||
*
|
||
* @param {Object} route Mapping information to be assigned to `$route.current` on route
|
||
* match.
|
||
*
|
||
* Object properties:
|
||
*
|
||
* - `controller` – `{(string|function()=}` – Controller fn that should be associated with
|
||
* newly created scope or the name of a {@link angular.Module#controller registered
|
||
* controller} if passed as a string.
|
||
* - `controllerAs` – `{string=}` – An identifier name for a reference to the controller.
|
||
* If present, the controller will be published to scope under the `controllerAs` name.
|
||
* - `template` – `{string=|function()=}` – html template as a string or a function that
|
||
* returns an html template as a string which should be used by {@link
|
||
* ngRoute.directive:ngView ngView} or {@link ng.directive:ngInclude ngInclude} directives.
|
||
* This property takes precedence over `templateUrl`.
|
||
*
|
||
* If `template` is a function, it will be called with the following parameters:
|
||
*
|
||
* - `{Array.<Object>}` - route parameters extracted from the current
|
||
* `$location.path()` by applying the current route
|
||
*
|
||
* - `templateUrl` – `{string=|function()=}` – path or function that returns a path to an html
|
||
* template that should be used by {@link ngRoute.directive:ngView ngView}.
|
||
*
|
||
* If `templateUrl` is a function, it will be called with the following parameters:
|
||
*
|
||
* - `{Array.<Object>}` - route parameters extracted from the current
|
||
* `$location.path()` by applying the current route
|
||
*
|
||
* - `resolve` - `{Object.<string, function>=}` - An optional map of dependencies which should
|
||
* be injected into the controller. If any of these dependencies are promises, the router
|
||
* will wait for them all to be resolved or one to be rejected before the controller is
|
||
* instantiated.
|
||
* If all the promises are resolved successfully, the values of the resolved promises are
|
||
* injected and {@link ngRoute.$route#$routeChangeSuccess $routeChangeSuccess} event is
|
||
* fired. If any of the promises are rejected the
|
||
* {@link ngRoute.$route#$routeChangeError $routeChangeError} event is fired.
|
||
* For easier access to the resolved dependencies from the template, the `resolve` map will
|
||
* be available on the scope of the route, under `$resolve` (by default) or a custom name
|
||
* specified by the `resolveAs` property (see below). This can be particularly useful, when
|
||
* working with {@link angular.Module#component components} as route templates.<br />
|
||
* <div class="alert alert-warning">
|
||
* **Note:** If your scope already contains a property with this name, it will be hidden
|
||
* or overwritten. Make sure, you specify an appropriate name for this property, that
|
||
* does not collide with other properties on the scope.
|
||
* </div>
|
||
* The map object is:
|
||
*
|
||
* - `key` – `{string}`: a name of a dependency to be injected into the controller.
|
||
* - `factory` - `{string|function}`: If `string` then it is an alias for a service.
|
||
* Otherwise if function, then it is {@link auto.$injector#invoke injected}
|
||
* and the return value is treated as the dependency. If the result is a promise, it is
|
||
* resolved before its value is injected into the controller. Be aware that
|
||
* `ngRoute.$routeParams` will still refer to the previous route within these resolve
|
||
* functions. Use `$route.current.params` to access the new route parameters, instead.
|
||
*
|
||
* - `resolveAs` - `{string=}` - The name under which the `resolve` map will be available on
|
||
* the scope of the route. If omitted, defaults to `$resolve`.
|
||
*
|
||
* - `redirectTo` – `{(string|function())=}` – value to update
|
||
* {@link ng.$location $location} path with and trigger route redirection.
|
||
*
|
||
* If `redirectTo` is a function, it will be called with the following parameters:
|
||
*
|
||
* - `{Object.<string>}` - route parameters extracted from the current
|
||
* `$location.path()` by applying the current route templateUrl.
|
||
* - `{string}` - current `$location.path()`
|
||
* - `{Object}` - current `$location.search()`
|
||
*
|
||
* The custom `redirectTo` function is expected to return a string which will be used
|
||
* to update `$location.path()` and `$location.search()`.
|
||
*
|
||
* - `[reloadOnSearch=true]` - `{boolean=}` - reload route when only `$location.search()`
|
||
* or `$location.hash()` changes.
|
||
*
|
||
* If the option is set to `false` and url in the browser changes, then
|
||
* `$routeUpdate` event is broadcasted on the root scope.
|
||
*
|
||
* - `[caseInsensitiveMatch=false]` - `{boolean=}` - match routes without being case sensitive
|
||
*
|
||
* If the option is set to `true`, then the particular route can be matched without being
|
||
* case sensitive

||
*

|

|
||
* It watches `$location.url()` and tries to map the path to an existing route definition.
|
||
*
|
||
* Requires the {@link ngRoute `ngRoute`} module to be installed.
|
||
*
|
||
* You can define routes through {@link ngRoute.$routeProvider $routeProvider}'s API.
|
||
*
|
||
* The `$route` service is typically used in conjunction with the
|
||
* {@link ngRoute.directive:ngView `ngView`} directive and the
|
||
* {@link ngRoute.$routeParams `$routeParams`} service.
|
||
*
|
||
* @example
|
||
* This example shows how changing the URL hash causes the `$route` to match a route against the
|
||
* URL, and the `ngView` pulls in the partial.

* @description
|
||
* The `$routeParams` service allows you to retrieve the current set of route parameters.
|
||
*
|
||
* Requires the {@link ngRoute `ngRoute`} module to be installed.
|
||
*
|
||
* The route parameters are a combination of {@link ng.$location `$location`}'s
|
||
* {@link ng.$location#search `search()`} and {@link ng.$location#path `path()`}.
|
||
* The `path` parameters are extracted when the {@link ngRoute.$route `$route`} path is matched.
|
||
*
|
||
* In case of parameter name collision, `path` params take precedence over `search` params.
|
||
*
|
||
* The service guarantees that the identity of the `$routeParams` object will remain unchanged
|
||
* (but its properties will likely change) even when a route change occurs.
|
||
*
|
||
* Note that the `$routeParams` are only updated *after* a route change completes successfully.
|
||
* This means that you cannot rely on `$routeParams` being correct in route resolve functions.
|
||
* Instead you can use `$route.current.params` to access the new route's parameters.
|
||
*
|
||
* @example
|
||
* ```js
|
||
* // Given:
|
||
* // URL: http://server.com/index.html#/Chapter/1/Section/2?search=moby
|
||
* // Route: /Chapter/:chapterId/Section/:sectionId
|
||
* //
|
||
* // Then
|

* $routeParams ==> {chapterId:'1', sectionId:'2', search:'moby'}

|
||
* # Overview
|
||
* `ngView` is a directive that complements the {@link ngRoute.$route $route} service by
|
||
* including the rendered template of the current route into the main layout (`index.html`) file.
|
||
* Every time the current route changes, the included view changes with it according to the
|
||
* configuration of the `$route` service.
|
||
*
|
||
* Requires the {@link ngRoute `ngRoute`} module to be installed.
|
||
*
|
||
* @animations
|
||
* | Animation | Occurs |
|
||
* |----------------------------------|-------------------------------------|
|
||
* | {@link ng.$animate#enter enter} | when the new element is inserted to the DOM |
|
||
* | {@link ng.$animate#leave leave} | when the old element is removed from to the DOM |
|
||
*
|
||
* The enter and leave animation occur concurrently.
|
||
*
|
||
* @knownIssue If `ngView` is contained in an asynchronously loaded template (e.g. in another
|
||
* directive's templateUrl or in a template loaded using `ngInclude`), then you need to
|
||
* make sure that `$route` is instantiated in time to capture the initial
|
||
* `$locationChangeStart` event and load the appropriate view. One way to achieve this
|
||
* is to have it as a dependency in a `.run` block:
|
||
* `myModule.run(['$route', function() {}]);`
|
||
*
|
||
* @scope
|
||
* @priority 400
|
||
* @param {string=} onload Expression to evaluate whenever the view updates.
|
||
*
|
||
* @param {string=} autoscroll Whether `ngView` should call {@link ng.$anchorScroll
|
||
* $anchorScroll} to scroll the viewport after the view is updated.
|
||
*
|
||
* - If the attribute is not set, disable scrolling.
|
||
* - If the attribute is set without value, enable scrolling.
|
||
* - Otherwise enable scrolling only if the `autoscroll` attribute value evaluated
|
||
* as an expression yields a truthy value.
