主框架mainFrame分成三个子框架,分别为leftFrame,rightFrame,topFrame,框架集代码如下:
<frameset rows="40,*" cols="*" frameborder="no" border="1" framespacing="0">
<frame src="top.aspx" name="topFrame" scrolling="No" noresize="noresize" id="topFrame" title="topFrame" />
<frameset cols="160px,*" frameborder="no" border="1" framespacing="0" id="leftFrame">
<frame src="left.aspx" scrolling="No" noresize="noresize" />
<frame src="right.aspx" noresize=noresize/>
</frameset>
</frameset>

<%...@ Page Language="C#" AutoEventWireup="true" CodeFile="top.aspx.cs" Inherits="top" %>

if(window.parent.leftFrame.cols=="160,*,0,0,0")...{
document.getElementById("menuICON").src="../image/Image00010.jpg";
document.getElementById("menuICON").alt="隐藏菜单"
window.parent.leftFrame.cols="*,0,0,0,0";
}

else...{
document.getElementById("menuICON").src="../image/Image00009.jpg";
document.getElementById("menuICON").alt="显示菜单"
window.parent.leftFrame.cols="160,*,0,0,0";
}
}
</script>
<body link="#66ff00" style="background-color: green">
<form id="form1" runat="server">
<div style="background-color: black">
<img style="cursor:hand; width: 81px; height: 46px;" src="../image/Image00009.jpg" alt="隐藏菜单" onclick="javascript:Show_Hide_Menu();" id="menuICON" />
</div>
</form>
</body>
</html>
隐藏leftFrame代码如下:

<%...@ Page Language="C#" AutoEventWireup="true" CodeFile="right.aspx.cs" Inherits="right" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">

<title></title>
</head>

<script language="javascript">...

function Show_Hide_Menu()...{

if(window.parent.leftFrame.cols=="160,*,0,0,0")...{
document.getElementById("menuICON").src="../image/Image00010.jpg";
document.getElementById("menuICON").alt="隐藏菜单"
window.parent.leftFrame.cols="0,*,0,0,0";
}

else...{
document.getElementById("menuICON").src="../image/Image00009.jpg";
document.getElementById("menuICON").alt="显示菜单"
window.parent.leftFrame.cols="160,*,0,0,0";
}
}

</script>
<body style="background-color: fuchsia">
<form id="form1" runat="server">
<img style="cursor:hand; width: 81px; height: 46px;" src="../image/Image00009.jpg" alt="隐藏菜单" onclick="javascript:Show_Hide_Menu();" id="menuICON" />
</form>
</body>
</html>
要注意的关键点:在主框架中设置标签frameset的id=leftFrame,在script脚本中改变的是主框架id为leftFrame的cols属性,而不是frame标签下的子框架名.







在topFrame中添加一个图标用来显示和隐藏leftFrame或是rightFrame,隐藏rightFrame代码如下:
