AJAX timeout error

[rallu]

When ajax call makes timeout error it first loads error function and after that it loads success function right after error.

In success method data is empty string and xmlhttprequest.status is 0.

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:

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.
