比如这个页面的“隐藏侧边栏”
http://bbs.csdn.net/
给个源码看看
其实就是设置 css,显示style.display='block',隐藏style.display='node'
我写了个例子，与csdn的实现方式可能不一样
<style> html,body{ width:100%;height:100%;padding:0px;margin:0px;overflow:hidden } #ifr1{height:100%;width:200px;float:left; } #ifr2{height:100%;width:100px float:right; } #hand{ position: absolute; z-index: 99; left: 200px; top: 48%; height: 50px; word-break: break-all; display: block; width: 20px; background: #fff; text-align: center; border: 1px solid #ccf; } </style> <iframe id="ifr1" src="http://bbs.csdn.net/left_menu"></iframe> <iframe id="ifr2" src="http://bbs.csdn.net/home"></iframe> <div id="hand" >隐藏</div> <script> function $(id){return document.getElementById(id) } var w,hand=$('hand'),ifr1=$('ifr1'),ifr2=$('ifr2'); hand.onclick=function(){ //点击隐藏按钮 var sty=ifr1.style,disp; sty.display=sty.display=='none'?'block':'none'; doResize(); } function doResize(){ //调整位置大小 var w=document.body.clientWidth; var sty=ifr1.style,disp; if(sty.display=='none'){ ifr2.style.width='100%'; hand.style.left='1px'; }else{ ifr2.style.width=w-220+'px'; hand.style.left='200px'; } } window.onload=window.onresize=doResize; doResize() </script> csdn用的是frameset，设置其中framset的cols属性为0,*收缩导航，设置为230,*展开导航
我这样写为什么“隐藏”按钮不显示？

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>左右布局侧边栏演示</title> </head><frameset rows="*" name="top_function" id="top_function" frameborder="NO" border="0" framespacing="0"> <frameset cols="20%,20,*" name="left_function" id="left_function" frameborder="NO" border="0" framespacing="0"> <frame src="left.html" name="leftFrame" id="leftFrame" title="leftFrame" /><frame src="left_close.html" name="left_close" id="left_close" scrolling="NO" noresize="noresize" title="left_close" style="border-color:#FF0000; border-style:solid; border-width:1px; padding-right:2" /> <frame src="right.html" name="mainFrame" id="mainFrame" title="mainFrame" /> </frameset></frameset> <noframes> <body><p>此网页使用了框架,但您的浏览器不支持框架。</p> </body> </noframes></html>
left_close.html文件在这里，和上面的放在一个目录里：
<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>关闭和显示侧边栏</title><SCRIPT LANGUAGE="javascript"><!--function shleft(){ if (parent.left_function.cols!="20%,20,*"){ parent.left_function.cols="20%,20,*" } else{ parent.left_function.cols="0,20,*" }}//--></SCRIPT></head><body onclick="shleft();"></body></html> 这个也没有效果：
if (parent.document.getElementById('top_function').rows!='10%,20,*'){ parent.document.getElementById('top_function').rows='10%,20,*' }else{ parent.document.getElementById('top_function').rows='0,20,*' }、脚本写最简单吧，。。。
