javascript - How do I debug a jQuery Ajax request?

Question

My code is:

var test = "it isn't working";
var response = $.ajax({
    type: 'GET',
    url: 'jquerydemo.php', //This is in the same site as the page calling this request, so it's not a same-domain error.
    success: function(){
            test = "it's working";
        },
    error: function(){
            alert("Error detected");
        }
 }).responseText;
alert(test);

I tested the status code and it came out to a 200 and the error function never goes off, but neither does the success function. Like I said in my comment, it isn't a same-origin policy error. It just stays saying "it isn't working". What's going on here?

Try this:

 error: function(jqXHR, textStatus, errorThrown) {
        console.log(JSON.stringify(jqXHR));
        console.log("AJAX error: " + textStatus + ' : ' + errorThrown);
 }
