title: Need a jQuery randomly selected identifier from options available
body: <p>I want to randomly select an id or value from one of the many option items in my select tag.  Also I was wandering how do I quickly count all the option tags in my select tag, and how can I randomly call an ID field efficiently so if I hit refresh, it will just pick another random id?  This is for a testing environment to auto fill a form out for qa people.</p>
  
  <p>Examples</p>
  
  <pre><code>&lt;select id="selectVendor"&gt;
   &lt;option value="55" selected="selected"&gt;Company A&lt;/option&gt;
   &lt;option value="56"&gt;Company B&lt;/option&gt;
   &lt;option value="57"&gt;Company XYZCYK&lt;/option&gt;
  ... &lt;/select&gt;
  </code></pre>
  
  <p>Finally I want to put the value of my selected id into my form field... Eventually I want to use ajax to populate my entire form with the randomly selected identifier when the page first loads. thx</p>
  
  <pre><code>&lt;input type="text" id="txtCompany" value="empty" /&gt;
  </code></pre>
