title: test if first child
body: <p>I'm testing to see if a row in a table is the first child. So far I have:</p>
  
  <pre><code>    //the loop works
  $('#GridFolderPopup').find('tr').each(function () {
  
      if ( $(this).is(:first) == true ) //this is the faulty line
      {
           $(this).addClass('GridFolderRow');
      };
  });
  </code></pre>
  
  <p>Any suggestions?</p>
  
  <p>Thanks</p>
