Changing the value of model defined in rootScope before leaving the current scope in AngularJS

How can we change the value of model defined in $rootScope before leaving the current scope in AngulrJS.

for example if the value of $rootScope.isPresent = true in

../testMe url. And if we hit another url with the same $rootScope

then how can we change the value of $rootScope.isPresent variable before displaying the view and initialing controller of new URL.

If you want to execute a block of code before changing states that lead to changing scopes, you can use:

$scope.$on("$destroy", function()
{
// your code goes here
});

AngularJS automatically fires a $destroy event when it tries to destroy the scope, which lets your code execute before leaving this state.
