为什么此无限滚动在IE中不起作用？

Question

The code below works as intended for Chrome and Firefox. For IE, it scrolls through the same content. I searched extensively for a solution but found nothing.

Header

<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script type="text/javascript">

$(window).scroll(function()
{
   if($(window).scrollTop() == $(document).height() - $(window).height())
   {

   $('div#loadmoreajaxloader').show();
   $.ajax(
   {
      url: "http://www.hackedflashgames.com/loadmore.php",
      success: function(html)
      {
         if(html)
         {
             $("#wrapper").append(html);
             $('div#loadmoreajaxloader').hide();
         }else
         {
             $('div#loadmoreajaxloader').html('<center>No more posts to show.</center>');
         }
      }
   });
}
});
</script>

loadmore.php

<?php
   include('db.php');
   $stmt = $db->prepare("SELECT * FROM games ORDER BY RAND() LIMIT 6");
   if($stmt->execute()){
      while ($row = $stmt->fetch()) {
         echo'
         content here
         ';
      }
   }
?>

IE is renown for it's aggressive caching especially with AJAX.

Try adding some random query string to the URL for the ajax call (like a timestamp).

You could also specify this in your code : $.ajaxSetup({ cache: false });

Thus you won't have to manually add the query string, jQuery will take care of it.
