File drop propagation

It can be useful to allow the drop event to propagate.
For example, I have a project where I show some drop boxes at different places on the page when the user drag a file over the window.

Here is my code :

angular.module('core')

    .factory('windowDragOverService', function ($rootScope, $document) {

        var dragover = 0;
        $rootScope.windowDragOver = false;

        $document
            .on('dragenter', function () {
                dragover++;
                $rootScope.windowDragOver = dragover > 0;
                $rootScope.$digest();
            })
            .on('dragleave drop', function () {
                dragover--;
                $rootScope.windowDragOver = dragover > 0;
                $rootScope.$digest();
            });

        return null;
    });

I need to know when there's a drop to hide those boxes.
