title: refresh a portion of HTML page with jquery
body: <p>Is there a way I could refresh or set to default just a portion of HTML (instead of reloading the whole) page with jquery? For example, I want to reset the following select on some click action. Please help. 
  Many thanks in advance.</p>
  
  <pre><code>....
  &lt;select id="refresh"&gt;
     &lt;option value="1" selected&gt;1&lt;/option&gt;
     &lt;option value="2"&gt;2&lt;/option&gt;
     &lt;option value="3"&gt;3&lt;/option&gt;
     &lt;option value="4"&gt;4&lt;/option&gt;
  &lt;/selected&gt;
  ......
  </code></pre>
