Question

I have:

<input name="X">

and in JavaScript:

$('input').on('change','[name=X]',function() {
        $('body').append('on change fired!');
    }
);
$('input[name=X]').change(function() {
    $('body').append('change fired!');
});
$(input[name='X']).val('test');

But my problem is that neither change event gets fired.

Answer 1

Changing the value of an input element programatically will not trigger any event. Alternatively, You can call .change after .val like below,

$('input[name=X]').val('test').change();

Edit: Also fixed the missing quotes around the input selector.
