Refreshing iframe contents in AngularJS

Question

I am writing an application which is part Angular and part jQuery. I am separating them by loading the jQuery content in an iFrame.

Upon a certain event (say, upon a ng-click), I need to refresh the iFrame. My Controller contains the following code:

$scope.refreshIframe = function() { //refresh the iFrame with id "anIframe" };

and the iFrame is:

<iframe id="anIframe" src="myUrl"></iframe>

As Paulo Scardine said, the right way to do it would be through a directive cause you shouldn't use controllers to manipulate DOM.

Something like this one could do :

.directive('refreshable', [function () {
    return {
        restrict: 'A',
        scope: {
            refresh: "=refreshable"
        },
        link: function (scope, element, attr) {
            var refreshMe = function () {
                element.attr('src', element.attr('src'));
            };

            scope.$watch('refresh', function (newVal, oldVal) {
                if (scope.refresh) {
                    scope.refresh = false;
                    refreshMe();
                }
            });
        }
    };
}])

Which could then be used like :

<iframe refreshable="tab.refresh"></iframe>

And :

$scope.refreshIframe = function(){
    $scope.tab.refresh = true;
}
