Fire Angularjs Event When Tab/browser Is Closed

I would like to fire JS code in Angularjs controller. I have this: $scope.$on('$destroy', function () { alert('page1'); }); This is working fine when I'm navi

Solution 1:

From the angular docs:

$destroy();

Removes the current scope (and all of its children) from the parent scope. Removal implies that calls to $digest() will no longer propagate to the current scope and its children. Removal also implies that the current scope is eligible for garbage collection.

The $destroy() is usually used by directives such as ngRepeat for managing the unrolling of the loop.

Just before a scope is destroyed, a $destroy event is broadcasted on this scope. Application code can register a $destroy event handler that will give it a chance to perform any necessary cleanup.

Note that, in AngularJS, there is also a $destroy jQuery event, which can be used to clean up DOM bindings before an element is removed from the DOM.

This just handles the situation where the scope itself is being destroyed, that does not seem to occur when the tab/browser is closed though.

You will have to use lower level methods onunload and onbeforeunload events to handle this situation, here is another post you may find useful:
