Aborting a jQuery getJSON XMLHttpRequest

Question

Turns out this was an artefact of a Firebug bug. The Ajax request was cancelled, but Firebug continued reporting it as active. Details here.

Answer 1

you may take a look at the JSONP-Plugin With this Plugin you have the ability to manually abort the request. Also take a look at "a cautionary note" at IBM's Technical library:

First and foremost, there is no error handling for JSONP calls. If the dynamic script insertion works, you get called; if not, nothing happens. It just fails silently. For example, you are not able to catch a 404 error from the server. Nor can you cancel or restart the request.
