从jquery $ GET请求页面加载特定div？

Question

I have something like this:

<a href="#" id="lol">LOL</a>        
<script type="text/javascript">

$('#lol').click(function(){ 
  $.get("<?php echo $host.'/index.php'?>", 
  { page: "topobjekt", index: "<?php echo $l;?>", pages: "<?php echo $pg+1;?>" },
  function(data){
           $('#primary_content').html(data);
                });
        });

Is it possible to load specific div(for instance #secondary_content) from my GET requested php page and load it into #primary_content target?

Answer 1

Why not modify your PHP script to handle the AJAX request specifically? You will save wasted bandwidth loading a whole page when you know all you need is one div.

Add a get variable and check for this to determine context.
