Note: This is a proper answer for a legacy version of AngularJS. See this question for updated versions.
$scope.$on('$routeChangeStart', function($event, next, current) {
// ... you could trigger something here ...
});
The following events are also available (their callback functions take different arguments):
- $routeChangeSuccess
- $routeChangeError
- $routeUpdate – if reloadOnSearch property has been set to false
See the $route docs.
There are two other undocumented events:
- $locationChangeStart
- $locationChangeSuccess
See What’s the difference between $locationChangeSuccess and $locationChangeStart?
