AngularJS: API: ng/service/$location
$location
- - $locationProvider
- - service in module ng
The $location service parses the URL in the browser address bar (based on the window.location) and makes the URL available to your application. Changes to the URL in the address bar are reflected into $location service and changes to $location are reflected into the browser address bar.
The $location service:
- Exposes the current URL in the browser address bar, so you can
- Watch and observe the URL.
- Change the URL.
- Synchronizes the URL with the browser when the user
- Changes the address bar.
- Clicks the back or forward button (or clicks a History link).
- Clicks on a link.
- Represents the URL object as a set of methods (protocol, host, port, path, search, hash).
