Now my problem is the <code><iframe></code> height should be set dynamically based on the contents in the <code><iframe></code>. I am using the following JavaScript for this purpose. It works fine in Firefox and Internet Explorer but not in Google Chrome and Safari. How to solve this problem?</p>

<pre><code>function sizeFrame() {
 jQuery("#myframe", top.document).css({ height: 0 });
 var iframe=document.getElementById('myframe');
 var iframeWin = iframe.contentWindow || iframe.contentDocument.parentWindow;
 var the_height=0;
