▲▲▲没有解决的iframe自适应高度问题，请大家看看。
现页面上有三个iframe ，一个控制顶部，一个控制左边，一个控制右边。
如下：
<table cellSpacing= "0 " cellPadding= "0 " width= "920 " align= "center " border= "0 "
style= "border-right: #cccccc 1px solid; border-top: #cccccc 1px solid; border-left: #cccccc 1px solid; border-bottom: #cccccc 1px solid; ">
<tr>
<td height= "190 " style= " BORDER-BOTTOM: #009900 1px solid "> <iframe src= "top.aspx " frameBorder= "0 " width= "100% " scrolling= "no " height= "190 "> </iframe>
</td>
</tr>
<tr >
<td >
<TABLE id= "Table1 " cellSpacing= "0 " cellPadding= "0 " width= "100% " align= "center " border= "0 " height= "100% " >
<TR>
<td width= "20% " > <iframe id= "left " src= "admin_left.aspx " frameBorder= "0 " width= "100% " height= "980 " scrolling= "no " > </iframe>
</td>
<TD width= "80% " > <iframe id= "main " name= "main " src= "admin_main.aspx " frameBorder= "0 " width= "100% " height= "980 " scrolling= "no " > </iframe>
</TD>
</TR>
</TABLE>
</td>
</tr>
<tr>
<td height= "100 " style= " BORDER-top: #009900 1px solid ">
<iframe src= "../foot.aspx " frameBorder= "0 " width= "100% " scrolling= "no " height= "100 "> </iframe>
</td>
</tr>
</table>
问题是：当点击左边的菜单时，如何让左边的iframe和右边的iframe的高度随新打开的页面的高度变化面变化。 我用梅花雪的方法能实现右边iframe的高度随之变化，但左边iframe菜单确自动下移，多出来很多空白。

原来是要联动啊
我直接给你看我针对类似问题的脚本源码吧
// frameId是自己，frameOtherId是边上那个，frameTopId是顶层的frame（如果存在这个嵌套的话）
function SetFrameHeight(height, frameId, frameOtherId, frameTopId)
{
if (top == parent) return;
var frame = parent.document.getElementById(frameId);
if (frame == null) return;
var frameTop = top.document.getElementById(frameTopId);
var frameOther = parent.document.getElementById(frameOtherId);
if (frameTop != null && frameOther != null)
{
var windowContent = frameOther.contentWindow;
var bodyHeight = 0;
if (windowContent != null && windowContent.document.body.scrollHeight)
{ //ie5+ syntax
bodyHeight = windowContent.document.body.scrollHeight;
}
else if (frameOther.contentDocument && frameOther.contentDocument.body.offsetHeight)
{ //ns6 syntax
frameTop.style.display = "block ";
bodyHeight = frameOther.contentDocument.body.offsetHeight + FFextraHeight;
}
if (height <= bodyHeight) height = bodyHeight;
//height += 20;
frameTop.height = height;
}
frame.style.height = height + "px ";
}

这是我用过的
<script type= "text/javascript ">
var iframeids=[ "message "]
var iframehide= "yes "
function dyniframesize()
{
var dyniframe=new Array()
for (i=0; i <iframeids.length; i++)
{
if (document.getElementById)
{
dyniframe[dyniframe.length] = document.getElementById(iframeids[i]);
if (dyniframe[i] && !window.opera)
{
dyniframe[i].style.display= "block "
if (dyniframe[i].contentDocument && dyniframe[i].contentDocument.body.offsetHeight)
dyniframe[i].height = dyniframe[i].contentDocument.body.offsetHeight + 50;
else if (dyniframe[i].Document && dyniframe[i].Document.body.scrollHeight)
dyniframe[i].height = dyniframe[i].Document.body.scrollHeight + 50;
}
}
if ((document.all || document.getElementById) && iframehide== "no ")
{
var tempobj=document.all? document.all[iframeids[i]] : document.getElementById(iframeids[i])
tempobj.style.display= "block "
}
}
}
if (window.addEventListener)
window.addEventListener( "load ", dyniframesize, false)
else if (window.attachEvent)
window.attachEvent( "onload ", dyniframesize)
else
window.onload=dyniframesize
</script>
<iframe src= "message.aspx " id= "message " runat= "server " frameborder= "0 " width= "100% ">
</iframe>

很多人反应在IE7里使用它会死机，那是因为在自适应高度时触发了 window.onresize 事件，而这个事件又去调用这个调整 <iframe> 高度的函数，产生了死循环调用。
//给你一段代码！你看看！费那事干吗！
