I'm getting the error [$rootScope:inprog] $apply already in progress whenever I trigger a click event on a hidden file upload input.

HTML:

<!-- button that calls function in controller -->
<button type="button" ng-click="uploadClicked()">Upload</button>
<!-- Upload input I'm triggering the click event on -->
<input type="file" accept="image/*" id="profile-photo" name="profile-photo" ng-hide="true"/>

AngularJS function in controller:

$scope.uploadClicked = function () {
    //Causes Error: [$rootScope:inprog] $apply already in progress and opens file dialog
    document.getElementById('profile-photo').click();

    //Causes Error: [$rootScope:inprog] $apply already in progress and does not open file dialog
    $('#profile-photo').trigger('click');
};

I'm not calling $apply or $digest anywhere in my controller. Why would this error be occurring?

Because angularjs does some actions in the background and your tiggered click conflicts at that place. –  t.niese Jan 3 at 11:11
    
That's rather unfortunate. Any advice on how to circumvent this? –  Jack Zach Tibbles Jan 3 at 11:12
    
Try wrapping it in a $timeout –  Rob J Jan 3 at 11:18

I just got a similar issue and i was able to fix it by wrapping the place where we click with a 

 setTimeOut(function(){uploadClicked();},0);

I guess by using it angular will be aware of that method and will not initialize another digest cycle on finding an click event.
