title: jQuery Set Selected Option Using Next
body: <p>How can I, using jQuery, set the "next" item of an already selected item as "selected."</p>
  
  <p>For example, if I have:</p>
  
  <pre><code>&lt;select&gt;
  &lt;option value="1" &gt;Number 1&lt;/option&gt;
  &lt;option value="2" selected="selected"&gt;Number 2&lt;/option&gt;
  &lt;option value="3" &gt;Number 3&lt;/option&gt;
  &lt;option value="4" &gt;Number 4&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>We can see that "Number 2" is selected, and using jQuery, I'd like to set "Number 3" as selected, and remove the selected "attribute" from "Number 2".  I'm assuming I need to use the <em>next</em> selector, but I'm not quite sure how to implement.</p>
