直接在页面上写javascript代码：
<script language="javascript"> <!-- var gt = unescape('>'); var popup = null; var over = "Launch Pop-up Navigator"; popup = window.open('', 'popupnav', 'width=500,height=500,resizable=0,scrollbars=auto'); // width=500,height=500为窗口长和宽 if (popup != null) { if (popup.opener == null) { popup.opener = self; } popup.location.href = 'update.htm'; } // --> </script>
