Question

Well, I got something like this:

HTML:

<div id="main" class="underline" >Hello</div>

JavaScript:

$('div').live('click', function(){
    $(this).toggleClass("underline");
});​

I have to run some function on event when div class was removed, and I haven’t got any permisions to edit functions that adding / removing class from div.

How can I catch that event when class is removing?

‘click’ event was used only as an example, so that class can be removen not only on the clicking

Answer 1

There is no such event. But you can do simpler:

$('div').live('click', function(){
    $(this).toggleClass("underline")
    if ($(this).hasClass("underline")) {
        alert("added");
    } else {
        alert("removed");
    }
});​
