title: synchronous jquery json request
body: <p>I need to make a synchronous request to the last.fm API, but when I use GET and json together, the request becomes asynchronous.</p>
  
  <p>my code:</p>
  
  <pre><code>$.ajax({
        async: false,
      dataType: "json",
      url: "http://ws.audioscrobbler.com/2.0/?method=artist.getimages&amp;artist="+artist+"&amp;api_key="+apiKey+"&amp;format=json&amp;callback=?",
      success: function(html){
            imgURL = html.images.image[1].sizes.size[0]["#text"];
      }
  });
  </code></pre>
  
  <p>If I remove dataType: "json" or use POST, it's synchronous again, but I'm dependant on using both json and GET.</p>
  
  <p>Any ideas?</p>
