$route is used for deep-linking URLs to controllers and views (HTML partials). It watches $location.url() and tries to map the path to an existing route definition.

Requires the ngRoute module to be installed.

You can define routes through $routeProvider's API.

The $route service is typically used in combined with the ngView directive and the $routeParam service.

Dependencies

  • $location
  • $routeParams

Methods

  • reload();

    Causes $route service to reload the current route even if $location hasn't changed.

    As a result of that, ngView  creates new scope and reinstantiates the controller.

  • updateParams(newParams);

    Causes $route service to update the current URL, replacing current route parameters with those specified in newParams. Provided property names that match the route's path segment definitions will be interpolated into the location's path, while remaining properties will be treated as query params.

Events

  • $routeChangeStart

    Broadcasted before a route change. At this point the route services starts resolving all of the dependencies needed for the route change to occur. Typically this involves fetching the view template as well as any dependencies defined in resolve route property. Once all of the dependencies are resolved $routeChangeSuccess is fired.

    The route change (and the $location change that triggered it) can be prevented by calling preventDefault method of the event. See$rootScope  .

  • $routeChangeSuccess

    Broadcasted after a route change has happened successfully. The resolve dependencies are now available in the current.locals property.

    ngView listens for the directive to instantiate the controller and render the view.
