Jquery: how to detect a disabled textbox's content has changed

Question

similar question asked here: How to detect a textbox's content has changed

but here my textbox is disabled.

i want to get notified as soon as my text box changed value.

The text box value changed because of AJAX callback.

not understanding.. please add more detail. If it truly has changed, then have you tried using a onChanged event? — Chris, Jun 04 '13 at 05:25
simple , you can't detect it.. change events only work with enabled inputs — Sushanth --, Jun 04 '13 at 05:25
are you changing it with code? if it is disabled how is it being changed? — Chris, Jun 04 '13 at 05:26
If it is disabled, you can't have keystrokes "to it". Changed through what, then? This is key here. — acdcjunior, Jun 04 '13 at 05:26
@Smith If disable you can't change the value, if possible make a [JSFiddle](http://jsfiddle.net/). We can try to solve it. — Praveen, Jun 04 '13 at 05:35
The `AJAX callback` changes the value so you can set a flag at the callback method. — Subir Kumar Sao, Feb 19 '14 at 08:08

First your Question is not clear..

But I assume what you want:-

So just a simple code to learn !!

HTML CODE:-

<div>
    First name: <input type="text" name="fname" id="myTextBox" ><br>
    <input type="button" name="submit" id="submit" value="Submit">

</div>

jQuery Code: -

$("#myTextBox").change("input", function() {
    alert("changed");
    $("#myTextBox").attr("disabled", "disabled");

});
$("#submit").click("input", function() {
    alert("clicked");
    $("#myTextBox").removeAttr("disabled", "disabled");

});

HTML

<input type="text" id="tb1" disabled  />
<input type="text" id="tb2"/>

jQuery

$('#tb1').change(function() { 
    alert('Don\'t try to be clever ');
    $(this).val('').attr('disabled','disabled');
});

when the user edit the disabled textbox value after focus is out of the textbox he gets an alert message and texbox again becomes disabled and value is set to null again.

Working Demo http://jsfiddle.net/cse_tushar/m5SVH/

If you text box is being dynamically edited through code without user adding the content then...you can remove the disabled class being applied to it to get hold of the value in it and compare with your previously stored value...
