php - Best way of loading external page with AJAX -

i'm not brilliant ajax please write me quick code switching div tag external page.

for example:

<script type="text/javascript"> // fun stuff here // </script>  <div id="random">hidden</div>  <a href="externalpage.php?random=78"></a> 

it awesome if content fade-in when it's loaded.

ok, have far (but doesn't seem working):

<ul>     <li><a href="random.html" class="load">ss3</a></li>     <li><a href="random.php" class="load">ss4</a></li> </ul>  <script type="text/javascript">     $(function(){         $("a.load").click(function (e) {              e.preventdefault();             $("#foliowrap").load($(this).attr("href"));         });     }); </script>  <div id="foliowrap"></div> 

you may want try javascript ajax loader jquery plugin can load page elements content via ajax , alters links in such way when click on links of ajax loaded content, new page element content loaded via ajax.

i suppose can hack add fade transition effects when new page element loaded.
