|
||
* Acts as a placeholder that Angular dynamically fills based on the current router state.
|
||
*
|
||
* Each outlet can have a unique name, determined by the optional `name` attribute.
|
||
* The name cannot be set or changed dynamically. If not set, default value is "primary".
|

*
|

* <router-outlet></router-outlet>
|

* <router-outlet name='left'></router-outlet>
|
||
* <router-outlet name='right'></router-outlet>
|
||
* ```
|
||
*
|
||
* Named outlets can be the targets of secondary routes.
|
||
* The `Route` object for a secondary route has an `outlet` property to identify the target outlet:
|
||
*
|
||
* `{path: <base-path>, component: <component>, outlet: <target_outlet_name>}`
|
||
*
|
||
* Using named outlets and secondary routes, you can target multiple outlets in
|
||
* the same `RouterLink` directive.
|
||
*
|
||
* The router keeps track of separate branches in a navigation tree for each named outlet and
|
||
* generates a representation of that tree in the URL.
|
||
* The URL for a secondary route uses the following syntax to specify both the primary and secondary
|
||
* routes at the same time:
|
||
*
|
||
* `http://base-path/primary-route-path(outlet-name:route-path)`
|
||
*
|
||
* A router outlet emits an activate event when a new component is instantiated,
|
||
* deactivate event when a component is destroyed.
|
||
* An attached event emits when the `RouteReuseStrategy` instructs the outlet to reattach the
|
||
* subtree, and the detached event emits when the `RouteReuseStrategy` instructs the outlet to
|
||
* detach the subtree.
|
||
*
|
||
* ```
|

/**
|
||
* @description
|
||
*
|
||
* When applied to an element in a template, makes that element a link
|
||
* that initiates navigation to a route. Navigation opens one or more routed components
|
||
* in one or more `<router-outlet>` locations on the page.
|
||
*
|
||
* Given a route configuration `[{ path: 'user/:name', component: UserCmp }]`,
|
||
* the following creates a static link to the route:
|
||
* `<a routerLink="/user/bob">link to user component</a>`
|
||
*
|
||
* You can use dynamic values to generate the link.
|
||
* For a dynamic link, pass an array of path segments,
|
||
* followed by the params for each segment.
|
||
* For example, `['/team', teamId, 'user', userName, {details: true}]`
|
||
* generates a link to `/team/11/user/bob;details=true`.
|
||
*
|
||
* Multiple static segments can be merged into one term and combined with dynamic segments.
|
||
* For example, `['/team/11/user', userName, {details: true}]`
|
||
*
|
||
* The input that you provide to the link is treated as a delta to the current URL.
|
||
* For instance, suppose the current URL is `/user/(box//aux:team)`.
|
||
* The link `<a [routerLink]="['/user/jim']">Jim</a>` creates the URL
|
||
* `/user/(jim//aux:team)`.
|
||
* See {@link Router#createUrlTree} for more information.
|
||
*
|
||
* @usageNotes
|
||
*
|
||
* You can use absolute or relative paths in a link, set query parameters,
|
||
* control how parameters are handled, and keep a history of navigation states.
|
||
*
|
||
* ### Relative link paths
|
||
*
|
||
* The first segment name can be prepended with `/`, `./`, or `../`.
|
||
* * If the first segment begins with `/`, the router looks up the route from the root of the
|
||
* app.
|
||
* * If the first segment begins with `./`, or doesn't begin with a slash, the router
|
||
* looks in the children of the current activated route.
|
||
* * If the first segment begins with `../`, the router goes up one level in the route tree.
|
||
*
|
||
* ### Setting and handling query params and fragments
|
||
*
|
||
* The following link adds a query parameter and a fragment to the generated URL:
|
||
*
|
||
* ```
|
||
* <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" fragment="education">
|
||
* link to user component
|
||
* </a>
|
||
* ```
|
||
* By default, the directive constructs the new URL using the given query parameters.
|
||
* The example generates the link: `/user/bob?debug=true#education`.
|
||
*
|
||
* You can instruct the directive to handle query parameters differently
|
||
* by specifying the `queryParamsHandling` option in the link.
|
||
* Allowed values are:
|
||
*
|
||
* - `'merge'`: Merge the given `queryParams` into the current query params.
|
||
* - `'preserve'`: Preserve the current query params.
|
||
*
|
||
* For example:
|
||
*
|
||
* ```
|
||
* <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" queryParamsHandling="merge">
|
||
* link to user component
|
||
* </a>
|
||
* ```
|
||
*
|
||
* See {@link UrlCreationOptions#queryParamsHandling}.
|
||
*
|
||
* ### Preserving navigation history
|
||
*
|
||
* You can provide a `state` value to be persisted to the browser's
|
||
* [`History.state` property](https://developer.mozilla.org/en-US/docs/Web/API/History#Properties).
|
||
* For example:
|
||
*
|
||
* ```
|
||
* <a [routerLink]="['/user/bob']" [state]="{tracingId: 123}">
|
||
* link to user component
|
||
* </a>
|
||
* ```
|
||
*
|
||
* Use {@link Router#getCurrentNavigation} to retrieve a saved
|
||
* navigation-state value. For example, to capture the `tracingId` during the `NavigationStart`
|
||
* event:
|
||
*
|
||
* ```
|
||
* // Get NavigationStart events
|
||
* router.events.pipe(filter(e => e instanceof NavigationStart)).subscribe(e => {
|
||
* const navigation = router.getCurrentNavigation();
|
||
* tracingService.trace({id: navigation.extras.state.tracingId});
|
||
* });
|
||
* ```
|
||
*
|
||
* @ngModule RouterModule
|
||
*
|
||
* @publicApi

/**

*
|
||
* @description
|
||
*
|
||
* Tracks whether the linked route of an element is currently active, and allows you
|
||
* to specify one or more CSS classes to add to the element when the linked route
|
||
* is active.
|
||
*
|
||
* Use this directive to create a visual distinction for elements associated with an active route.
|
||
* For example, the following code highlights the word "Bob" when the router
|
||
* activates the associated route:
|
||
*
|
||
* ```
|
||
* <a routerLink="/user/bob" routerLinkActive="active-link">Bob</a>
|
||
* ```
|
||
*
|
||
* Whenever the URL is either '/user' or '/user/bob', the "active-link" class is
|
||
* added to the anchor tag. If the URL changes, the class is removed.
|
||
*
|
||
* You can set more than one class using a space-separated string or an array.
|
||
* For example:
|
||
*
|
||
* ```
|
||
* <a routerLink="/user/bob" routerLinkActive="class1 class2">Bob</a>
|
||
* <a routerLink="/user/bob" [routerLinkActive]="['class1', 'class2']">Bob</a>
|
||
* ```
|
||
*
|
||
* To add the classes only when the URL matches the link exactly, add the option `exact: true`:
|
||
*
|
||
* ```
|
||
* <a routerLink="/user/bob" routerLinkActive="active-link" [routerLinkActiveOptions]="{exact:
|
||
* true}">Bob</a>
|
||
* ```
|
||
*
|
||
* To directly check the `isActive` status of the link, assign the `RouterLinkActive`
|
||
* instance to a template variable.
|
||
* For example, the following checks the status without assigning any CSS classes:
|
||
*
|
||
* ```
|
||
* <a routerLink="/user/bob" routerLinkActive #rla="routerLinkActive">
|
||
* Bob {{ rla.isActive ? '(already open)' : ''}}
|
||
* </a>
|
||
* ```
|
||
*
|
||
* You can apply the `RouterLinkActive` directive to an ancestor of linked elements.
|
||
* For example, the following sets the active-link class on the `<div>` parent tag
|
||
* when the URL is either '/user/jim' or '/user/bob'.
|
||
*
|
||
* ```
|
||
* <div routerLinkActive="active-link" [routerLinkActiveOptions]="{exact: true}">
|
||
* <a routerLink="/user/jim">Jim</a>
|
||
* <a routerLink="/user/bob">Bob</a>
|
||
* </div>
|
||
* ```
|
||
*
|
||
* The `RouterLinkActive` directive can also be used to set the aria-current attribute
|
||
* to provide an alternative distinction for active elements to visually impaired users.
|
||
*
|
||
* For example, the following code adds the 'active' class to the Home Page link when it is
|
||
* indeed active and in such case also sets its aria-current attribute to 'page':
|
||
*
|
||
* ```
|
||
* <a routerLink="/" routerLinkActive="active" ariaCurrentWhenActive="page">Home Page</a>
|
||
* ```

||
*

* @ngModule RouterModule
