title: JQuery How to find out what the ajax error is?
body: <p>I have the following bit of code which I'm just trying out by running in firebug</p>
  
  <pre><code>$.ajax({
    type:"POST",
    url:"http://mpdomain/WebService.asmx/Operation",
    data: "{'parameter1': '44906'}", 
    contentType: "application/json;charset=utf-8",
    dataType: "json",
    success: function(data) { alert("succsess") },
    error: function(e, ts, et) { alert(ts) }
  })
  </code></pre>
  
  <p>In theory it should work.  However the error handler is triggered, and ts is simply set to "error".  How do I get more detail about what's gone wrong?</p>
