本地开发环境中的jQuery AJAX请求失败

Question

I'm trying to test a jQuery/Javascript script on my local development environment. For some reason the script calls the error delegate. I've attempted to make sure I'm not performing a cross-domain request.

    $.ajax({
            url: 'http://localhost',
            success: function(data, textStatus, jqXHR) {
                console.log('success');
                console.log(data);
            },
            error: function(jqXHR, textStatus, errorThrown) {
                console.log(textStatus);
                console.log(errorThrown);
                console.log(jqXHR);
            }
        });
    return marker;
}

I'm running a WAMP stack. Here is my output:

error
undefined
XMLHttpRequest { mozResponseArrayBuffer=ArrayBuffer, status=0, more...}

Does anyone know what could be the issue?

Try replacing the absolute url:

url: 'http://localhost'

with a relative one:

url: '/'

If this doesn't solve your problem FireBug and/or Fiddler will give you more hints about what is going on and why the AJAX request fails.
