JSONP inner workings with AJAX

It works exactly the way you thought it should:

It adds an async script tag into head , and immediately removes it after calling the callback function.

Update

Only to inform, I was using the JSONP flickr API in the example above:

setTimeout(function() {
  $.getJSON('http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=?', {
      tags: 'jquery',
      tagmode: 'any',
      format: 'json'
    },
    function(data) {
      $.each(data.items, function(i, item) {
        $('<img />').attr('src', item.media.m).appendTo('#images');
      });
    });
}, 2000);
