title: Open a new webpage from a combo box onclick event for the option selected
body: <p>I have page with several combo-boxes. The combo boxes options are populated with this PHP code. ($id and $label are collected from an ini file.)</p>
  
  <pre><code>&lt;?echo'&lt;select id="wbox" name="MPR"&gt;';
  foreach($config[MPR] as $id=&gt;$label){
      switch ($id)
      {
      case ($id==select):
      echo'&lt;option value="0" selected="selected"&gt;&lt;/option&gt;';
      break;
      case ($id&gt;0 &amp;&amp; $id&lt;=10):
      echo'&lt;optgroup label="'.$label.'"&gt;';
      break;
      case ($id&gt;10 &amp;&amp; $id&lt;=20):
      echo'&lt;/optgroup&gt;';
      break;
      default:
      echo'&lt;option value="'.$id.'"&gt;'.$label.'&lt;/option&gt;';
      }
  }
  echo'&lt;/select&gt;';?&gt;
  </code></pre>
  
  <p>At the end a submit button is clicked, and the values are handed off to another php script that redirects the user to a specific web page.</p>
  
  <p>I would like to be able to direct the user to the selected page in an onclick event with the combo box. (Each option would be a new page, corresponding to the value assigned in the option.)</p>
