请帮忙解决一下!!
我这儿有几个文件:
main.htm
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</head>
<frameset rows="100,*" cols="*" frameborder="NO" border="1" framespacing="0">
<frame name="top" scrolling="NO" noresize src="menu.htm" target="left">
<frameset cols="25%,*" border="0" >
<frame name="left" src="left.htm" target="main">
<frame name="main" src="source/input.php">
</frameset>
</frameset>
<noframes><body bgcolor="#FFFFFF" text="#000000">
</body></noframes>
</html>
请问如何改写menu.htm中的链接,同时更换left.htm和source/input.php两个文件为其它两个文件
menu.htm
<?php_track_vars ?>
<?session_start();
include("../db.php");
?>
<body leftmargin="2" topmargin="0" marginwidth="0" marginheight="0" oncontextmenu="event.returnValue=false">
<table border=0 width=95% align="left" cellpadding="0" cellspacing="0">
<tr>
<td height="18"><img src="image/bg.gif" width="776" height="88" usemap="#Map" border="0"></td>
</tr>
</table>
<map name="Map">
<area shape="rect" coords="86,13,186,74" href="left.htm" target=left >
<area shape="rect" coords="209,14,308,75" href="left2.htm" target=left>
<area shape="rect" coords="330,12,431,75" href="left1.htm" target=left>
<area shape="rect" coords="455,12,557,74" href="setup/setup.php" target=main>
<area shape="rect" coords="580,14,679,75" href="left3.htm" target=left>
</map>
</body>
谢谢各位
