need help speeding up tag cloud filter for IE
<p>Any ideas on how to speed this up in IE (the filtering process performs decent in Firefox, but almost unusable in IE). Basically, it's a tag cloud with a filter text box to filter the cloud.</p>

<pre><code>&lt;html&gt;

&lt;head&gt;

&lt;script type="text/javascript" src="jquery-1.3.2.min.js"&gt;&lt;/script&gt;
&lt;script type="text/javascript"&gt;
    $(document).ready(function(){


        $('#tagFilter').keyup(function(e) { 
            if (e.keyCode==8)
            {   
                $('#cloudDiv &gt; span').show();
            }

            $('#cloudDiv &gt; span').not('span:contains(' + $(this).val() + ')').hide(); 
        });

    });
&lt;/script&gt;

&lt;/head&gt;


&lt;body&gt;
&lt;input type="text" id="tagFilter" /&gt;
&lt;div id="cloudDiv" style="height: 200px; width: 400px; overflow: auto;"&gt;
&lt;script type="text/javascript"&gt;

for (i=0;i&lt;=1300;i++)
{
    document.write('&lt;span&gt;&lt;a href="#"&gt;Test ' + i + '&lt;/a&gt;&amp;nbsp;&lt;/span&gt;');
}
&lt;/script&gt;
&lt;/div&gt;

&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>thanks,
rodchar</p>
