title: Abort JSONP ajax request with jQuery
body: <p>I'm using a JSONP ajax call to load some content from a different domain, and all this stuff is executed if the user causes a "mouseover" on a button.</p>
  
  <p>I can capture the $.ajax() call return as a xhr object, and use it to abort the ajax request each time the user causes a "mouseover". But the JSONP callback function still gets called, and this causes an error, and I think it is beacuse the xhr.abort() method does not prevent the callback function to be called.</p>
  
  <p>I've tried surrounding the $.ajax() call with try{}catch(e){}, but after I call the xhr.abort() method, the error continues.</p>
  
  <p>Is there a way to handle that exception?</p>
  
  <p>The raised exception is like this (according to Firebug):
  <strong>jQuery16102234208755205157_1308941669256 is not a function</strong></p>
  
  <p>And the exception's internal structure is like this:
  <strong>jQuery16102234208755205157_1308941669256({... my json data from a different domain....})</strong></p>
