No error handling in jQuery AJAX call invoked

Question

I'm trying to make the AJAX call bark and squick at me so I'm executing a totally wrong URL. For some reason, none of the methods that are supposed to do the barking och squicking is invoked.

What is the reason?

$.ajax({
  url: "http://totally.wrong.url",
  dataType: 'jsonp',
  error: function () { alert("bark 1"); },
  failure: function () { alert("bark 2"); }
})
  .fail(function () { alert("squick"); })
  .done(function () { alert("woof"); });

Of course, if I change the URL to point to the correct WCF service, I get an approving woof.

According to jQuery API, I should use fail and done syntax but I'll be fine either way.

Deprecation Notice: The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

@KhanhTO Tried that too. To no avail. Sorry for not mentioning it. — Konrad Viltersten, Jul 05 '13 at 08:18
Check this link : http://stackoverflow.com/questions/4281274/jquery-ajax-404-handling. They propose using `ajaxError` — Khanh TO, Jul 05 '13 at 08:23

Ajax with JSONP and Cross Site Requests won't trigger the error callback.

Look at the accepted answer in this question: jQuery Ajax 404 Handling

Hopefully this should explain what you need to make it work.

I don't know if failure is supposed to work but I always use "error" and "success" instead. So try:

   $.ajax({
      url: "http://totally.wrong.url",
      dataType: 'jsonp',
      error: function () { alert("bark");},
      success: function () { alert("woof");} 
      }
    })

Didn't work either. I forgot to say that. I started with *error* and then tried *failure*. :) – Konrad Viltersten Jul 05 '13 at 08:21
Yes sorry I saw you mentioned that after I posted it. – Anton Aderum Jul 05 '13 at 08:32
Also, according to the information at one of the links I've received, there's no error message delivered when using JSONP. Are you able to make the code in your reply work and do you see it actually barking? – Konrad Viltersten Jul 05 '13 at 14:26

$.ajax({
  url: "http://totally.wrong.url",
  dataType: 'jsonp',
  **error**: function () { alert("bark"); }
})
  .fail(function () { alert("squick"); })
  .done(function () { alert("woof"); });

error is the request fail callback function and not failure
