title: jquery: select options and background color
body: <p>Greetings,
  Having a such select box:</p>
  
  <pre><code>&lt;select id="events"&gt;
      &lt;option value="1" style="background-color:green;"&gt;Event 1&lt;/option&gt;
      &lt;option value="2" style="background-color:yellow;"&gt;Event 2&lt;/option&gt;
      &lt;option value="3" style="background-color:blue;"&gt;Event 3&lt;/option&gt;
      &lt;option value="4" style="background-color:red;"&gt;Event 4&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>At the <strong>initial</strong> browser render of this selectbox and <strong>each time a selection is done</strong>, I want the selectbox "events" to get the background-color of the selected option.</p>
  
  <p>How can this be achieved via jquery or via regular javascript ?</p>
