求解决一下问题
代码如下!~
<!--#include file="main.asp"-->
<html>
<head>
<meta http-equiv="refresh" content="5;url=main.asp">
<meta http-equiv="Content-Language" content="zh-cn">
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<link href=site.css rel=stylesheet>
</head>
<body>
<p> </p>
<table border="0" width="450" align=center>
<tr>
<td width="100%"><b>操作结果</b></td>
</tr>
<tr>
<td width="100%">
<hr size="1">
</td>
</tr>
<tr>
<td width="100%"><font color="#FF0000">操作成功!</font><BR>系统将在5面种后自动返回!</td>
</tr>
<tr>
<td width="100%"> </td>
</tr>
</table>
</body>
</html>
怎样使返回界面返回到上一页!~相当于IE上面的后退功能!~
