[jQuery] Unable to detect Ajax cross domain error (Firefox)

[Kris Schoofs]

Hi,

Using Firefox 3.5.3 (and firebug) I run the Ajax code below locally
(i.e. not on the same domain as the Ajax URL). Unlike in IE, this code
is not working in Firefox due to cross-domain Ajax restrictions. Of
course, as soon as I upload the code to my PHP server on the same
domain it runs fine.

However, when running the code locally the 'error'-callback never gets
triggered. Instead, the 'success'-callback always get triggered even
though the request clearly failed (as confirmed by the fact that
'OnSuccess' is unable to show any data received from the server). Even
firebug does not report any errors. Somehow, I expected to see an
error like "Permission denied to call method XMLHttpRequest.open".

I would feel much more comfortable about my code when I was 100% sure
that I can catch all errors. So, I'm wondering why I'm unable to
detect this obvious error?

$.ajax({
    type: "GET",
    url: "http://dvd.identifier.cdfreaks.com/alive2.php";;,
    cache: false,
    data: "para1=value1&para2=value2",
    success: function(data, textStatus)
    {
        $("#container_onsuccess").html("@"+Counter+"#"+data+"#"+textStatus);
    },
    error: function (XMLHttpRequest, textStatus, errorThrown)
    {
        
$("#container_onerror").html("@"+Counter+"#"+textStatus+"#"+errorThrown);
    },
    complete: function (XMLHttpRequest, textStatus)
    {
        $("#container_oncomplete").html("@"+Counter+"#"+textStatus);
        Counter++;
        ScheduleNextAjaxRequest();
    }
});

Thanks,

Kris
