Passing a querystring value through a javascript window.open
<p>I need to pass the pass value stored in a asp hiddenfield to a querystring using the window.open.</p>

<pre><code>onclick="window.open('../New/FeedbackV4.aspx','FeedbackWindow','width=960,height=640,scrollbars=yes,resizable=yes,status=yes')"
</code></pre>

<p>I need to get the value of the hidden field and pass it as a querystring</p>
