当 JQuery 修改值时，angularjs 检测输入的变化

Question

I have a input (text + button). When I press the button (select date and time) and the library set value in input text. I like to detect changes with angularJs or JQuery for this field but it does not work.

I tried with (in directive):

$scope.$watch('namevarmodel', function() {
    alert('test');
},true);

And JQuery:

<script>
    $('#nameinput').change(function() {
        alert( "test." );
    });
</script>

Any suggestions?

Angular provides directives that automagically keeps watching your inputs. You could check the angular documentation for ng-change and you could do something like this:

<input ng-change="action()">...</input>

I hope this helps.
