JSONP error handler for cross origin requests is triggered only after timeout

Description

The JSONP error handler is triggered for HTTP errors (e.g. 404) for same origin requests immediately, but for cross origin requests only after the timeout occurred. This can be easily fixed with adding script.onerror (see Zepto.js).

Tested browsers:

Affected: Chrome 26, Firefox 20, Safari 6, Opera 12.14

Not affected: IE 9

I will provide a patch later.

Are you still interested in providing a patch? How widespread is .onerror support in XHR?

@dmethvin, yes, but I am quite busy at the moment. I think script.onerror together with script.onreadystatechange covers the most browsers, but I am not sure about Opera. I found out that it is already fixed in jQuery 2. The reason why it works for same origin requests is that it uses XMLHttpRequest internally (altough the format is JSONP).
