1.5 Ajax not triggering error for bad URL

[rdibona@…]

This simple AJAX call includes a URL that doesn't exist. In 1.5 in Firefox it does not display the alert meaning the error is not being caught (or causes a runtime error in Firebug). In 1.4.4 it properly catches the error in the textStatus.

$('#cmdDetails').bind('click', function()
{
    $.ajax
    ({
        type: "GET",
        dataType: "json",
        url: "server/fakeurl.php",
        complete : function(data, textStatus, jqXHR)
        {
            alert(textStatus);
        }
    })
});

Thanks for taking the time to contribute to the jQuery project by writing a bug report!

After checking your report I made this  live test case based on your description. I can't seem to reproduce the behavior you described, as I get an alert saying "error" in FF.

So please submit a reduced test case, which reproduces the issue you are experiencing, on  http://jsfiddle.net. So that we can investigate this issue further. Also make sure to read the link given below, in order to provide a most useful bug report.

If you could also include what version of Firefox you're testing with that would be of benefit.

It had to do with making the AJAX call from within a form's submit button click event. For some reason, FireFox 3.6.13 did not like this. But it doesn't really have to do with the AJAX call itself, so you can close this ticket.

Thanks very much and I apologize that I did not enter the bug using the proper protocol.

Sorry, I dont like to create jsFiddle acc just to say how to reproduce the bug. Change URL.

url: " http://google.com/fakeurl.php?jsonpCallback=?"

JSONP does not trigger error callbacks, neither local nor global. In 1.5, 1.4.4, 1.4.3, 1.4.2.

Because I can't reliably do so. And the documentation clearly states this behavior.  http://api.jquery.com/jQuery.ajax

error: This handler is not called for cross-domain script and JSONP requests.

Just wanted to bring this bug back up to life, as it seems that using HTTPS in the connection prevents the error from showing up.
