frameset框架如何使左边页面显示，隐藏?wj-wangjun

1. 框架页面

< frameset  rows ="95,76%,60"  border ="0"  frameSpacing ="0"  frameBorder ="0" >
         < frame  name ="header"  src ="Top.aspx"  scrolling ="no"  noresize style ="BORDER-RIGHT: #0099ff 2px ridge; BORDER-TOP: #0099ff 2px ridge; BORDER-LEFT: #0099ff 2px ridge; BORDER-BOTTOM: #0099ff 2px ridge" >
         < frameset  cols ="200,*"  id ="middle" >
             < frame  name ="contents"  src ="LeftFrame.aspx"  style ="BORDER-RIGHT: #0099ff 2px ridge; PADDING-RIGHT: 2px; BORDER-TOP: #0099ff 3px; PADDING-LEFT: 2px; MARGIN-LEFT: 2px; BORDER-LEFT: #0099ff 2px ridge; MARGIN-RIGHT: 2px; BORDER-BOTTOM: #0099ff 3px" >
             < frame  name ="main"  src ="Main.aspx"  scrolling ="auto"  style ="BORDER-RIGHT: #0099ff 2px ridge; PADDING-RIGHT: 2px; BORDER-TOP: #0099ff 1px; BORDER-LEFT: royalblue 3px; MARGIN-RIGHT: 2px; BORDER-BOTTOM: royalblue 1px" >
         </ frameset >
         < frame  name ="footer"  src ="Bottom.aspx"  scrolling ="no"  style ="BORDER-RIGHT: #0099cc 2px ridge; BORDER-TOP: #0099cc 2px ridge; BORDER-LEFT: #0099cc 2px ridge; BORDER-BOTTOM: #0099cc 2px ridge" >
     </ frameset >
</ html >

2. 在Main.aspx 文件做显示隐藏的按钮。（方法一：）

<% @ Page language="c#" Codebehind="Main.aspx.cs" AutoEventWireup="True" Inherits="BYD_SPCSystem.DesktopModules.Main"  %>
<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"  >
< html >
     < head >
         < title > Main </ title >
         < meta  content ="Microsoft Visual Studio .NET 7.1"  name ="GENERATOR" >
         < meta  content ="C#"  name ="CODE_LANGUAGE" >
         < meta  content ="JavaScript"  name ="vs_defaultClientScript" >
         < meta  content ="http://schemas.microsoft.com/intellisense/ie5"  name ="vs_targetSchema" >
< script  type ="text/javascript" >    
  <!--   
    
  function  shleft(){   
  if   (parent.middle.cols=="0,*")   
  {   
  parent.middle.cols="200,*"   
  document.getElementById("p1").innerHTML="隐";   
  document.getElementById("p2").innerHTML="藏";   
  }   
  else   
  {   
  parent.middle.cols="0,*"   
  document.getElementById("p1").innerHTML="显";   
  document.getElementById("p2").innerHTML="示";   
  }   
  }   
function TABLE1_onclick() {

}

  //-->   
   </ script >    
     </ head >
     < body  >
         < form  id ="Form1"  method ="post"  runat ="server" >
           < table    border ="0"     cellpadding ="0"    cellspacing ="0"  style ="width: 1%; height: 1%;position:absolute; left: 0px; top: 75px;"  id ="TABLE2"  onclick ="return TABLE1_onclick()" >    
             < tr >    
                 < td  bgcolor ="#99ccff"  valign ="middle"  onclick ="shleft()"  style ="FONT-SIZE: 8pt; CURSOR: hand; COLOR: white; width: 1px; height: 126px;" >    
                   < p  id ="p1" > 隐 </ p >    
                   < p  id ="p2" > 藏 </ p >    
                   < p > 左 </ p >    
                   < p > 部 </ p >    
                  </ td >
              </ tr >
            </ table >

var disptool = true;
function coro(){
if(disptool){
parent.main.cols='0,*';
document.all.tool.src="../Img/open.gif";
disptool = false;
}
