Answer 2

Reign001(afdf)没有这么复杂吧，那套系统使用的JAVASCRIPT

Answer 3

<script language="javascript">
//dreamweaver自带的函数
// Example: obj = findObj("image1");
function findObj(theObj, theDoc)
{
  var p, i, foundObj;
  
  if(!theDoc) theDoc = document;
  if( (p = theObj.indexOf("?")) > 0 && parent.frames.length)
  {
    theDoc = parent.frames[theObj.substring(p+1)].document;
    theObj = theObj.substring(0,p);
  }
  if(!(foundObj = theDoc[theObj]) && theDoc.all) foundObj = theDoc.all[theObj];
  for (i=0; !foundObj && i < theDoc.forms.length; i++) 
    foundObj = theDoc.forms[i][theObj];
  for(i=0; !foundObj && theDoc.layers && i < theDoc.layers.length; i++) 
    foundObj = findObj(theObj,theDoc.layers[i].document);
  if(!foundObj && document.getElementById) foundObj = document.getElementById(theObj);
  
  return foundObj;
}//点开菜单，同级菜单收缩。var oldObj='none';                用来保存上次点开的菜单的id
var start=1;                      程序开始标志
var clicked=0;                    菜单展开标志，默认全部关闭
function controlMenu(theObj)
//用来控制菜单的函数
{
with(findObj(theObj).style)
{
display=display=='none'?'':'none';
}
}
function setMenu(theObj)
//关键代码，默认值为菜单全部收缩。
{
if(start)
         //第一次运行时start为真。展开菜单
{
controlMenu(theObj);
clicked=1;
}
else
         //start为假
{
if(oldObj!=theObj)
                  //点击的菜单跟上次不同
{
                           //如果有菜单为展开状态，则将其关闭。
if(clicked)controlMenu(oldObj);
                           //展开新菜单
controlMenu(theObj);
                           //设置展开标志
clicked=1;
}
else
                  //点击的菜单跟上次点击一样
{
                           //收缩菜单
controlMenu(theObj);
//设置展开标志为否
                           clicked=!clicked;
}
}
start=0;          //设置程序开始标志为否。
oldObj=theObj;    //保存当前状态
}
</script>
--------------------------------------------
程序还有需要优化的地方。不过工作的很好。遗憾的是，只支持一级菜单。哪位高人修改一下？我认为多级菜单实在不需要收缩其他菜单的功能，所以当时没考虑。何况，还要判断是否在同一分支下，决定是否展开或收缩。麻烦啊~~ 怕怕
