jQuery ajax (jsonp) ignores a timeout and doesn’t fire the error event

by

jQuery 1.5 and higher have better support for error handling with JSONP requests. However, you need to use the $.ajax method instead of $.getJSON. For me, this works:

var req = $.ajax({
    url : url,
    dataType : "jsonp",
    timeout : 10000
});

req.success(function() {
    console.log('Yes! Success!');
});

req.error(function() {
    console.log('Oh noes!');
});

The timeout seems to do the trick and call the error handler, when there is no successful request after 10 seconds.

I did a little blogpost on this subject as well.
