为什么我的网站出现JQuery AJAX错误，并且没有响应头？

Question

When I click on "Request and Invite", you'll notice that there's a JQuery error...but it's weird.

The code is pretty simple. The error seems to be happening on JQuery's file. I tried previous versions of JQuery (both compressed and uncompressed), but there were always problems.

Make sure you return false from the form submit handler or the ajax call won't have time to execute:

$('#waitlist_form').submit(function() {
    var the_email = $('#waitlist_box').val();
    $.ajax({
        type: 'POST',
        url: '/waitlist/submit',
        data: { email: the_email },
        beforeSend: function() {
        },
        success: function(html) {
            $('#waitlist_button').html('Thanks!');
        }
    });
    return false;
});
