  <pre><code>b.createDocumentFragment is not a function (jQuery)
  </code></pre>
  
  <p>My function is</p>
  
  <pre><code>function tweetCount(url) {  
      $.getJSON("http://urls.api.twitter.com/1/urls/count.json?url="+url+"&amp;callback=?", function(data) {
        count = data.count
        $(this).append(count);
     })
  }
  </code></pre>
  
  <p>I've tried lots of different way but can't seem to find out why it doesn't like "append". "count" is a number and something like alert(count) works, but not append!</p>
  
  <p>Any help?!
