jQuery selector not working in IE
<p>sample html:</p>

<pre><code>&lt;tr&gt;
    &lt;td class="hidden tblLnk"&gt;8163&lt;/td&gt; 
&lt;/tr&gt;
&lt;tr&gt;
    &lt;td class="hidden tblLnk"&gt;8163&lt;/td&gt; 
&lt;/tr&gt;
&lt;tr&gt;
    &lt;td class="hidden tblLnk"&gt;8164&lt;/td&gt; 
&lt;/tr&gt;
</code></pre>

<p>this method should return a unique array of text from rows with a specific td class.  { 8163, 8164 } in our sample.</p>

<p>works in ffs and chrome but not in ie8 or safari.  can you spot the problem?</p>

<pre><code>function getUniqueIds()
{
     var tblLnks = new Array();

     $('td.tblLnk').each(function()
     {
        tblLnks.push($(this).text().trim());
     });

     return tblLnks.unique();
}
</code></pre>
