title: Check if an option exist in select element without JQuery?
body: <p>Unfortunately I don't have access to JQuery and all it's nicety.  But I do have access to JavaScript.  How do I check if an OPTION exist in a HTML Select?</p>
  
  <p>EDIT:  To clarify, I need to know if an option exist.  So for example:</p>
  
  <pre><code>&lt;select&gt;
   &lt;option&gt;Volvo&lt;/option&gt;
   &lt;option&gt;Saab&lt;/option&gt;
   &lt;option&gt;Mercedes&lt;/option&gt;
   &lt;option&gt;Audi&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I check if "Hyndai" is an OPTION, and it is not.</p>
