Class LinkComponent

public
import LinkComponent from '@ember/routing/link-component';

LinkComponent renders an element whose click event triggers a transition of the application's instance of Router to a supplied route by name.

LinkComponent components are invoked with {{#link-to}}. Properties of this class can be overridden with reopen to customize application-wide behavior.

Show:

Module: @ember/routing

The collection of functions, keyed by name, available on this ActionHandler as action targets.

These functions will be invoked when a matching {{action}} is triggered from within a template and the application's current route is this route.

Actions can also be invoked from other parts of your application via ActionHandler#send.

The actions hash will inherit action handlers from the actions hash defined on extended parent classes or mixins rather than just replace the entire hash, e.g.:

banner.js
1
2
3
4
5
6
7
8
9
import Mixin from '@ember/mixin';

export default Mixin.create({
  actions: {
    displayBanner(msg) {
      // ...
    }
  }
});
app/routes/welcome.js

import Route from '@ember/routing/route';
import CanDisplayBanner from '../mixins/can-display-banner';

export default Route.extend(CanDisplayBanner, {
  actions: {
    playMusic() {
      // ...
    }
  }
});

// `WelcomeRoute`, when active, will be able to respond
// to both actions, since the actions hash is merged rather
// then replaced when extending mixins / parent classes.
this.send('displayBanner');
this.send('playMusic');

Within a Controller, Route or Component's action handler, the value of the this context is the Controller, Route or Component object:

app/routes/song.js
1
2
3
4
5
6
7
8
9
10
11
import Route from '@ember/routing/route';

export default Route.extend({
  actions: {
    myAction() {
      this.controllerFor("song");
      this.transitionTo("other.route");
      ...
    }
  }
});

It is also possible to call this._super(...arguments) from within an action handler if it overrides a handler defined on a parent class or mixin:

Take for example the following routes:

route.js
1
2
3
4
5
6
7
8
9
import Mixin from '@ember/mixin';

export default Ember.Mixin.create({
  actions: {
    debugRouteInformation() {
      console.debug("It's a-me, console.debug!");
    }
  }
});
debug.js

import Route from '@ember/routing/route';
import DebugRoute from '../mixins/debug-route';

export default Route.extend(DebugRoute, {
  actions: {
    debugRouteInformation() {
      // also call the debugRouteInformation of mixed in DebugRoute
      this._super(...arguments);

      // show additional annoyance
      window.alert(...);
    }
  }
});

Bubbling

By default, an action will stop bubbling once a handler defined on the actions hash handles it. To continue bubbling the action, you must return true from the handler:

app/router.js
1
2
3
4
5
Router.map(function() {
  this.route("album", function() {
    this.route("song");
  });
});
app/routes/album.js

import Route from '@ember/routing/route';

export default Route.extend({
  actions: {
    startPlaying: function() {
    }
  }
});

import Route from '@ember/routing/route';

export default Route.extend({
  actions: {
    startPlaying() {
      // ...

      if (actionShouldAlsoBeTriggeredOnParentRoute) {
        return true;
      }
    }
  }
});
Module: @ember/routing

The CSS class to apply to LinkComponent's element when its active property is true.

Module: @ember/routing

The WAI-ARIA role of the control represented by this view. For example, a button may have a role of type 'button', or a pane may have a role of type 'alertdialog'. This property is used by assistive software to help visually challenged users navigate rich web applications.

The full list of valid WAI-ARIA roles is available at: http://www.w3.org/TR/wai-aria/roles#roles_categorization

Module: @ember/routing

By default the {{link-to}} component will bind to the href and title attributes. It's discouraged that you override these defaults, however you can push onto the array if needed.

Module: @ember/routing

By default the {{link-to}} component will bind to the active, loading, and disabled classes. It is discouraged to override these directly.

Module: @ember/routing

Standard CSS class names to apply to the view's outer element. This property automatically inherits any class names defined by the view's superclasses as well.

Module: @ember/routing

Used to determine when this LinkComponent is active.

Module: @ember/routing

Returns the current DOM element for the view.

Module: @ember/routing

The HTML id of the component's element in the DOM. You can provide this value yourself but it must be unique (just as in HTML):

1
{{my-component elementId="a-really-cool-id"}}

If not manually set a default value will be provided by the framework. Once rendered an element's elementId is considered immutable and you should never change it. If you need to compute a dynamic value for the elementId, you should do this when the component or element is being instantiated:

1
2
3
4
5
6
7
8
export default Component.extend({
  init() {
    this._super(...arguments);

    var index = this.get('index');
    this.set('elementId', `component-id${index}`);
  }
});
Module: @ember/routing

If false, the view will appear hidden in DOM.

Module: @ember/routing

Layout can be used to wrap content in a component.

Module: @ember/routing

Available since v1.13.0

Enables components to take a list of parameters as arguments. For example, a component that takes two parameters with the names name and age:

component.js
1
2
3
4
5
6
7
8
9
import Component from '@ember/component';

let MyComponent = Component.extend();

MyComponent.reopenClass({
  positionalParams: ['name', 'age']
});

export default MyComponent;

It can then be invoked like this:

1
{{my-component "John" 38}}

The parameters can be referred to just like named parameters:

1
Name: {{name}}, Age: {{age}}.

Using a string instead of an array allows for an arbitrary number of parameters:

component.js
1
2
3
4
5
6
7
8
9
import Component from '@ember/component';

let MyComponent = Component.extend();

MyComponent.reopenClass({
  positionalParams: 'names'
});

export default MyComponent;

It can then be invoked like this:

1
{{my-component "John" "Michael" "Scott"}}

The parameters can then be referred to by enumerating over the list:

1
{{#each names as |name|}}{{name}}{{/each}}
Module: @ember/routing

Sets the rel attribute of the LinkComponent's HTML element.

Module: @ember/routing

Determines whether the LinkComponent will trigger routing via the replaceWith routing strategy.

Module: @ember/routing

Sets the tabindex attribute of the LinkComponent's HTML element.

Module: @ember/routing

Tag name for the view's outer element. The tag name is only used when an element is first created. If you change the tagName for an element, you must destroy and recreate the view element.

By default, the render buffer will use a <div> tag for views.

Module: @ember/routing

Available since v1.8.0

Sets the target attribute of the LinkComponent's HTML element.

Module: @ember/routing

Sets the title attribute of the LinkComponent's HTML element.
