title: Infinite scrolling within ajax-loaded page
body: <p>I have a page(let's call it 1.php) that loads 2.php into a div-box using jQuery-ajax.
  2.php prints 20 records from my database.
  When I reach the bottom of the div-box when scrolling, I want it to load the next 20 records.
  Like Facebook, Twitter, etc, etc does it. </p>
  
  <p>Now, I've gotten this behaviour, but only when loading 2.php on it's own!
  But not within the div-box.</p>
  
  <p>How do I go about this?</p>
  
  <p>Thanks in advance!</p>
