Angularjs Controller destructor

Question

I have an AngularJs app. I use Controllers for some child scopes. In every Controller I can set a number of variables that belong to the corresponding Child Scope. When AngularJs instantiate a controller, there is a constructor where I can set a default value to my child-scope variables.

Do I have a controller "destructor"? How do I know when a controller is closing and the scope is being cleaned (destroyed by the $destroy function)?

Thanks!

You have to listen to the $destroy event, e.g.:

function MyController($scope, ...) {     ...     $scope.$on("$destroy", function handler() {         // destruction code here     }); }
