http://api.jquery.com jsonp interface?

Hello all,

I'm learning jQuery with the book "Learning jQuery 3rd edition".
On chapter 13 dealing with advanced ajax request, the first example deals with JSONP request on the http://api.jquery.com site (to search for terms).

Looking for the term "attr" in the example search box, the JSONP request fails (google chrome version 24). The following message appears in the console:

The code used to perform the request was the following: ($('#title') is an input text field which holds the "attr" string)

$.ajax({
      url: 'http://api.jquery.com/jsonp/',
      dataType: 'jsonp',
      data: {
        title: $('#title').val()
      },
      success: function(data) {
        console.log(data);
      }
    });

What's wrong with the code? Did the jsonp interface on the jquery site changed?
Thanks for your help.

Best regards,

Erwin
