test if first child
<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>
