I would like have a on listener something like below for all controllers which are instantiated. And, I don't want to include this expression in all of my controllers. I just wanted to set this listener on all new scopes created in angualr js application. 

$scope.$on('somebroadcastedevent', function someEvent() {

});

How can I accomplish?

Override ngController directive.

module.directive('ngController', function () {
   return {
      link: function (scope) {
          // register the listener here. 
          scope.$on('somebroadcastedevent', function someEvent() {

          });
      }
   }
})

  • Hi Vinay thanks for the answer. How about extending a base controller as suggested in this link?http://stackoverflow.com/q/16539999/1847031 – raghu Mar 28 '15 at 11:58
  • This approach will not create any inheritance. To inject common properties in all the controllers this approach is very simple. – Vinay K Mar 28 '15 at 13:16
  • Just a note, this approach will not work when controller is instantiated using $controller. – Vinay K Mar 28 '15 at 13:17
