Hi,

It seems error callback function doesn't work properly. Since 1.4.2 jQuery doesn't call error callback in case of timeout. It always executes "success" callback with status 0. I tried to turn off timeout, set it to 10s. In the end I was wondered when I passed 10ms the error callback function fired. My application supports offline mode and I need to know when the request failed so I can suppose that user if offline.

I use the following code:

#!php
var opt = {
    contentType: 'application/x-www-form-urlencoded',
    async:       true,
    global:      false,
    cache:       false,
    //dataType:    'json',
    ifModified:  false,
    type:        'POST',
    url:         "?m=synch&a=write",
    timeout:     10*1000,
    error:       function(xhr) { console.log("error", arguments); },
    success:     function() { console.log("success", arguments); }
};

jQuery.ajax(opt);

Thanks!

Probably fixed when #6060 was fixed.
