title: Object doesn't support property or method remove
body: <p>I am using extjs and trying to remove a dom element dynamically like this-</p>
  
  <pre><code>if (Ext.getElementById('a'))
      Ext.getElementById('a').remove();
  </code></pre>
  
  <p>This works fine in Chrome. I am running application on IE9 as well but it throws the error- Object doesn't support property or method remove</p>
  
  <p>Please let me know if there is a workaround. </p>
