title: why does "datatype: jsonp" not work?
body: <p>I have the following code, trying to get google's URL shortener to work.</p>
  
  <pre><code>$.ajax({
                    type: 'POST',
                    url: "https://www.googleapis.com/urlshortener/v1/url?key=AIzaSyDQ33gAu7thkpw_oW9VTcxR6YGhimcfik",
                    contentType: 'application/json',
                    data: '{ longUrl: "' + match +'"}',
                    dataType: 'jsonp',
                    success: function(id){
                    $('#menu').html(id);
                    }
                  });
  </code></pre>
  
  <p>The issue here is, when the datatype is just json, the request is made, but nothing is returned. when it is changed to jsonp, nothing happens at all. any ideas?</p>
