//l利用到的脚本代码：
 <script language="javascript">
function show(ok,close)
  ...{
 eval(document.all(ok)).style.display=(eval(document.all(ok)).style.display=="none")?"":"none";
eval(document.all(close)).style.display=(eval(document.all(close)).style.display=="none")?"":"none";
 }
function closeall()
...{
  for (i=1;i<=6;i++) ...{
document.all("layer"+i).style.display="none";
 }
}
</script>
//body代码： 注意z-index的值越大，越显示在外面。利用layer2来消失div提示。第一次加载div不显示，点击IMG后显示。
