title: ExtJS get value of hidden form field
body: <p>First off, thanks for your patience I'm pretty new to Ext. All I'm trying to do is get the value of a hidden form field on an HTML page and store its value a variable inside an ext script. Here's what I'm working with:
  HTML PAGE:</p>
  
  <pre><code>&lt;form name="myForm"&gt;
  &lt;input type="hidden" id="accountID" name="divAccountID" value="463"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>Ext Page:</p>
  
  <pre><code>var myAccountID = Ext.ComponentQuery.query('panel[name=myForm] #accountID');
  </code></pre>
