AngularJS [removed] in one controller is being triggered on another controller

Question

Here is my problem, I have two views (View1 and View2) and a controller for each view (Ctrl1 and Ctrl2). In View1 I\'m trying to warn the user before he leaves the page accident

Answer 1

I just attempted the above solution, and that wasn't working for me. Even manually typing delete window.onbeforeunload in the console wouldn't remove the function. I needed to set the property to undefined instead.

$scope.$on('$destroy', function(e){
  $window.onbeforeunload = undefined;
});
