JavaScript / jQuery: change monitor to element?

Question

Is there any way (other than creating a new event) that I can tell when a particular CSS class was added to the element?

Answer 1

If you don't have access to the code adding the class, there is a jQuery plugin called livequerythat will allow you to run the code when elements are added to the DOM (or when you do things like adding a class to an element).

http://brandonaaron.net/code/livequery/docs

$('div.myClass').livequery(function() {
     alert('myClass was added');
});

$('#someDiv').addClass("myClass");  // The livequery code will run

This works specifically with jQuery methods.
