title: How to highlight clicked div?
body: <p>I have a series of divs like this:</p>
  
  <pre><code>&lt;div id="listofstuff"&gt;
      &lt;div id="anitem"&gt;
          &lt;span class="itemname"&gt;Item1&lt;/h3&gt;&lt;/span&gt;
          &lt;span class="itemdescruption"&gt;AboutItem1&lt;/span&gt;
      &lt;/div&gt;
      &lt;div id="anitem"&gt;
          &lt;span class="itemname"&gt;Item2&lt;/h3&gt;&lt;/span&gt;
          &lt;span class="itemdescruption"&gt;AboutItem2&lt;/span&gt;
      &lt;/div&gt;
      &lt;div id="anitem"&gt;
          &lt;span class="itemname"&gt;Item3&lt;/h3&gt;&lt;/span&gt;
          &lt;span class="itemdescruption"&gt;AboutItem3&lt;/span&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I want to make to so when the user clicks on an "anitem", the one that was clicked is highlighted and the itemname only pops up in an alertbox.</p>
