JQuery :: Link Tracking Plugin + JSONP + Opera?

I'm tryng to develop a link tracker, something like google analytics. The goal is to get a command like this:

$('html').trackAllLinks(optional options);
$('a').trackAllLinks(optional options);

Now i developed a javascript that could do just what i need but the problem is it doesn't work in every browser as it should be. Because i want to track a link click i need to make a request to my server to say that the link has been clicked. The first problem i had was that i needed to make a cross domain ajax call. But this is fixed by using JSONP. Now my code looks like this:

[Code]...

The first idea was that i wouldn't do anything in the success of the jsonp call and just let the request go, but because this didn't work when i clicked on an external link, i changed it to wait on a response before opening the link. The problem with this code is that it doesn't work in Opera, no request is being send to the server Now i know that JSONP mimics the ajax call by adding a script tag to the page which loads the script of the given url. Now i think when i do this in Opera the dynamically loaded javascript isn't executed. In Firefox, IE, Chrome, Safari it works but not in Opera.

Another idea i had was by dynamicly adding an image to the page. But this has the same problem in Opera and i was unable to track an external link in Safari and Chrome (Webkit.
