Question

How to get rid of extended $.extend() function from a specific target object. Example: By reloading parts of the DOM with XHR, I’m able to detect the appearance of the object like this:

// Initliaize:
$('#sausage').catsup();
    ...
// Inside fn.catsup():
if($('body').find($(this)).size() == 0) // object has gone

But how can I kill fn.catsup()? This seems not to work:

$(this).clearQueue();
$(this).stop();
$(this).unbind();
delete $(this);

If I understood the question, you want to remove your function from jQuery.

use this:

$.fn.catsup = null;

Or as suggested by @Matt:

delete $.fn.catsup
