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

Unregister the onbeforeunload event when the controller which defined it goes out of scope:

$scope.$on('$destroy', function() {
    delete window.onbeforeunload;
});
