[jQuery] Pass custom data through to $.ajax success callback


I am looking for a way to pass a custom data object through to the
$.ajax success function.
Specifically, I want to pass a <tr> DOM reference so that when a
specific request completes I know which table row from which to remove
my activity indicator.
I've scoured the docs but can't see the way to do this with JQuery.
Thank-you
