jquery event which is called when the readonly value of the text box is changed automatically

Question

Hi Guys.

Is there any jquery event which is called when the readonly value of the text box is changed automatically

I want to call an event (jquery) which should be called when the readonly value of the textbox is changed some how by other jquery events.

Early Reply is highly appreciated.

Answer 1

There is no event for this (not one you would want to attach to, a general DOM change event handler would have horrible performance).

If you expanded on the context a bit, there may be another solution to get what you're after, for example what's setting it to readonly?

Answer 2

would the change() method not work?

$('input:readonly').change(function() {
   alert("Readonly input changed!!");
})

Answer 3

You could add a function that will be executed every N seconds (via setInterval) and check for the field value. It is very ugly, though.

Answer 4

You could add a change event to your <input> and test for the readonly attribute:

$('input').change(function(){
    if($(this).attr('readonly') == true){
        // do something fancy
    } 
});
