[jQuery] jquery form plugin problem

[dth]

Hi,

I'm trying to use the form plugin from malsup.org to submit a form
with ajax, but it does not seem to work with options.

This works:

                            $("#loginform").ajaxSubmit(function(obj,
statusText) {
                                    alert(obj);
                            });

This does not work (nothing happens):

                            $("#loginform").ajaxSubmit({
                                dataType: "json",
                                success: function(obj, statusText) {
                                    alert(obj);
                                }
                            });

Oh, and by the way. Is there any way to get access to the request in
the 'success' function - to obtain status codes, content-type header
etc.?

Thanks,
