title: Possible to get percent complete of an ajax API request?
body: <p>I'm making a mobile app which has a number of API requests made via ajax.</p>
  
  <p>I was wondering if there was a way to get a 'percent complete' figure that I could turn into a (accurate enough) loading bar.</p>
  
  <p>My ajax calls look like:</p>
  
  <pre><code>$.ajax({
      url: 'http://WEBADDRESS&amp;format=json',
      dataType: 'json',
      success: function(results) {
      },
      error: function(results){
      }
  })
  </code></pre>
