Catching a JSONP error on a cross-domain request

Question

I\'m using jQuery.getJSON() on a URL (different domain) which may not exist. Is there a way for me to catch the error \"Failed to load resource\"? It seems that try/catch do

Answer 1

What your complaining about is a client-side error saying that you tried to download a resource from the server.

This is build into the browser and it allows your browser to tell the client or the developers that the downloading of a resource from the internet failed. This has nothing to do with JavaScript and is a more low level error thrown on the HTTP that is caught by the browser.

If you want any hope of catching it your going to need to drop 3rd party ajax libraries and deal with the XMLHTTPRequest object on a much lower level, even then I doubt you can do anything about it.

Basically when you see this error then find out what object your trying to get that doesn't exist or couldn't be accessed. Then either stop accessing it or make it accessible.
