Everything that I've seen says you have to check the length of the
element you are looking for.
So I think you want
pre
if($(this).parents('ul').length==0){
$(this).addClass(active);

/pre
If a parent UL was found, the length would be 0

$.fn.extend({
// checks to see if an element exists
// if no callback is supplied, returns
// a boolean value stating if the element
// exists, otherwise executes the callback
exists: function (callback) {

You're right. This was a small oversight on my end, though, it would have

your reply. :)
The reason I use var that = this; is not for scope but rather to ensure that
the proper object is being referenced inside the
