title: jQuery remove duplicated div with class name
body: <p>So basically my div generates like this:</p>
  
  <pre><code>&lt;div class="test className"&gt;content&lt;/div&gt;
  &lt;div class="test className"&gt;content&lt;/div&gt;
  &lt;div class="test className"&gt;content&lt;/div&gt;
  ..
  &lt;div class="test className"&gt;content&lt;/div&gt;
  </code></pre>
  
  <p>and I'm trying to remove duplicated divs and keep last one only! any quick ideas? thanks!</p>
