title: jQuery selector to obtain li object from specific unordered list
body: <p>I'm trying to obtain a specific li element from a unordered list. </p>
  
  <p>I'm doing it this way:</p>
  
  <pre><code>var listItem = $('ul.selectedItems').filter(list[i].ID);
  </code></pre>
  
  <p>Any idea of why this isn't working?</p>
