Extending jQuery's className selector

How can I override $(".className") such that

if(className="xyz") then alert("Hello")

and then do what JQuery is doing.

Is this what you mean?

if ($('div[class="xyz"]').length) {
  alert('Hello');
}

From what I understand, you want to override/extend the method in jQuery that finds nodes. I can't find any hooks and/or listeners that can be attached to that functionality in the code, so I guess you'll have to modify the source code if you want to achieve this functionality.

I'd suggest adding some sort of event listener interface so you can attach this to arbitrary selectors that fit your needs.
