第一步:把如下代码加入<head>区域中 <script language="JavaScript"> <!-- var gt = unescape('%3e'); var popup = null; var over = "Launch Pop-up Navigator"; popup = window.open('', 'popupnav', 'width=225,height=235,resizable=1,scrollbars=auto'); if (popup != null) { if (popup.opener == null) { popup.opener = self; } popup.location.href = '01.htm'; } // --> </script> 第二步:新建tan.htm文件(注意要与上面的对应!) 第三步：在新建文件中加入如下代码(注意两个文件要在同一目录下) <script language="JavaScript"> setTimeout("self.close()",10000) </script>
