Fire onchange event for TextBox when readonly is true

rated 0 times [ 51] [ 7] / answers: 1 / hits: 31174 / 12 Years ago, tue, january 15, 2013, 12:00:00

I am trying to have some functionality on change of a textbox which is readonly.
But when I am trying to update the textbox using javascript, the change event is not firing for the textbox.

<script type=text/javascript>

        $(document).ready(function () {

            $('input[id$=_txtTest]').bind(change, function () {

                alert(test);

            });

                        });

        function ChangeText() {

            $('input[id$=_txtTest]').val('hello');

         }

    </script>

I am calling ChangeText method on click of a button. But it is not firing the textchange event for the textbox.

Can anybody tell me what is wrong here?

Well you have to do this way: http://jsfiddle.net/kmvSV/1/

 $(document).ready(function () {

   $('input[id$=_txtTest]').bind(change, function () {

     alert($(this).val());

   });

   $('button').bind(click, function () {

     $('input[id$=_txtTest]').val('hello').trigger('change');

   });

 });
