[jQuery] Getting XMLHttpRequest status

[corey]

Hey, all. I'm sending an AJAX request, and in addition to executing
functions on Success or failure, I want to get the Status of the
XMLHttpRequest object (404, 401, etc). It's passed into the functions,
but I can't figure out how to retrieve it.

$.ajax({
        type: "GET",
        url: "member_check.php",
        dataType: "xml",
        error: function(event, XMLHttpRequest, ajaxOptions, thrownError) {
                alert( XMLHttpRequest.status ) // << ????
        }
)

Any ideas? Thanks!

Corey
