title: jquery ajax post querystring
body: <p>Just getting to grips with this jquery and ajax thing. </p>
  
  <p>I want to run a small script on a page and I've gathered I need to use POST from a jquery function to do this. I'm having trouble sending querystrings along though, what am I doing wrong?</p>
  
  <pre><code>$.post("inventory.php?use=" + drag_item.attr('id'));
  </code></pre>
  
  <p>the <code>drag_item.attr('id')</code> is a small one word text, is that the right way of doing it?</p>
