removeClass() is not getting applied in IE6.0
<p>I am working with jQuery and when I call the <code>removeClass()</code> function is not working in IE6.0, what could be the reason? The <code>.removeClass()</code> function is working as expected in IE8.0 and Firefox.</p>

<pre><code>&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;my Page&lt;/title&gt;
    &lt;style type="text/css"&gt;
        .message-header{
            margin-left:10px;
            padding-left:15px; 
            border:1px solid #fff; 
            border:0px solid #ddd;  
        }  

        .message-header.closed{  
            margin-left:10px;  
            padding-left:15px; 
            border:1px solid #fff;    
            border:0px solid #ddd;   
        } 
    &lt;/style&gt;
&lt;/head&gt;
&lt;body&gt;
    this is my jsp.
    &lt;script&gt;
        $(document.ready(function()){
            var $content = $('.message-header', node);{

            if (action == 'hide') {
                $content.addClass('closed');
                $content.hide();
            }
            else if (action == 'view') {
                $content.removeClass('closed');
                $content.show();
            }
        });
    &lt;/script&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>
