title: Load content from website into an attribute
body: <p>I need to update the <code>href</code> of a link (<code>#product_buy</code>) with a URL that can be found on another page inside the <code>#product_buy_source</code> div. Here's the jQuery.</p>
  
  <pre><code>$('body').ready(function(){
  
      $('#product_buy').attr('href', function(){
          $(this).load('http://cdn.jeremyblaze.com/theme_info.html #Altitude .product_buy_source');
      });
  
  });
  </code></pre>
  
  <p>And here's the link that needs to be edited.</p>
  
  <pre><code>&lt;a href="#" id="product_buy"&gt;Purchase&lt;/a&gt;
  </code></pre>
  
  <p>I sense the jQuery I've used is completely wrong. Is anybody able to make it work? Here's a little <a href="http://jsfiddle.net/WbWj4/" rel="nofollow">fiddle</a></p>
