I have a list of links on the page and sometimes they have events attached to them and sometimes not (they just don't do anything). I want to say, 'if this element has no event handlers (basically it doesn't do anything), then add a class of disabled to it. I googled it but didn't find anything for detecting event handlers. Does anyone know of a way to do something like this??

This should get you a list of events:

jQuery(theElement).data('events');

You could try this:

$("element").data("events");

I use the following, tested in IE, FF and Chrome:

if(typeof document.getElementById("elementname").onchange === "function"){ 
    alert("has a function");
} else {
    alert("no function");
}
