title: Get parent <li> item with jQuery
body: <p>I am trying to get the parent <code>&lt;li&gt;</code> when I click on a specific <code>&lt;li&gt;</code> item.</p>
  
  <p><a href="http://jsfiddle.net/doonot/GjbZk/" rel="noreferrer">http://jsfiddle.net/doonot/GjbZk/</a></p>
  
  <p>So let's say I click on <code>submodule 1</code>, I get the clicked ID with <code>$(this).attr('id');</code>
  How can I now get the ID of the parent <code>&lt;li&gt;</code> which is in this case <code>module 1</code>?</p>
  
  <p>Please note that my tree is quite big, so it has to be flexible. </p>
  
  <p>Thanks a lot, much appreciate your answer.</p>
