Update Angular model after setting input value with jQuery

Hope this is useful for someone.

I was unable to get the jQuery('#myInputElement').trigger('input') event to be picked up my angular app.

I was however, able to get angular.element(jQuery('#myInputElement')).triggerHandler('input') to be picked up.

The accepted answer which was triggering input event with jQuery didn't work for me. Creating an event and dispatching with native JavaScript did the trick.

$("input")[0].dispatchEvent(new Event("input", { bubbles: true }));

ngModel listens for "input" event, so to "fix" your code you'd need to trigger that event after setting the value:

$('button').click(function(){
    var input = $('input');
    input.val('xxx');
    input.trigger('input'); // Use for Chrome/Firefox/Edge
    input.trigger('change'); // Use for Chrome/Firefox/Edge + IE11
});

For the explanation of this particular behaviour check out this answer that I gave a while ago: "How does AngularJS internally catch events like 'onclick', 'onchange'?"

But unfortunately, this is not the only problem you have. As pointed out with other post comments, your jQuery-centric approach is plain wrong. For more info take a look at this post: How do I “think in AngularJS” if I have a jQuery background?).
