点击文字后菜单慢慢展开_菜单导航特效

点击文字后才展开的菜单，实际上点击文字后展开的是一个层，层里面放的是一个表格，菜单是在表格里，通过这个例子你会明白JS是如何控制一个DIV层展开的，这是现在比较流行和通用的方法。

<html>
<head>
<title>点击文字让菜单层展开</title>
<meta http-equiv="Content-Type" mrc="text/html; charset=gb2312">
</head>
<body topmargin="0" leftmargin="0" bgcolor="#FFFFFF" onclick="menuHide();">
<script>
document.onmousewheel=function()
{
status=event.wheelDelta;
}
</script>
<meta http-equiv="Content-Type" mrc="text/html; charset=gb2312">
<style>

</style>
<script language=javascript>
var run=0;
var show=0;
function menuRow()
{
  show=1;
  run=1;
  menu.style.pixelTop-=5;
  if(menu.style.pixelTop>0)
setTimeout('menuRow();','5');
  else
    run=0;
}
function menuShow()
{
  if(!run && !show)
  {
    menu.style.visibility='visible';
menup.style.visibility='visible';
    menu.style.pixelTop=200;
    menuRow();
  }
}
function menuHide()
{
  if(!run && show)
