var jmold=1;
function onChangesx(i){   //显示/隐藏信息
if (jmold!=i)  lmall();
childSort = findObj("chd" + i);
if(childSort.style.display=="none")
  { childSort.style.display="";}
else
  { childSort.style.display="none";}
jmold=i;
}
function lmall()
{
try {
//Srt=document.all("chd" + jmold);
Srt = findObj("chd" + jmold);
Srt.style.display="none";
}
catch(e)
   {alert(e.description);}
}说说思路:
先判断是不是刚才点的节点,是就直接判断是隐藏还是显示.
否则就把刚才显示的节点隐藏了.也可先把除传递过来的节点外所有的节点先隐藏了
都不满意的话，我给你一个树型目录：
