FLASH导航现在基本上已经是过时了，但是我们可以用jQuery来实现flash效果，非常的不错。

$(document).ready(function(){
$(".menu").mouseover(function(){
var div = $(this).children(".menu_b");
var span = $(this).children("span");
//隐藏字体，往右移动20px
span.stop(true,false).animate({opacity:'0',left:'20px'},200);
//显示背景动画
div.stop(true,false).animate({width:'100px',marginLeft:'-50px',height:'1px',opacity:'1'},300);
div.animate({height:'40px',marginTop:'-20px',opacity:'1'},300);
//显示字体，往左移动20px
span.animate({opacity:'1',left:'0px'},300);
span.css({color:'#FFF'});
});
$(".menu").mouseout(function(){
var div = $(this).children(".menu_b");
var span = $(this).children("span");
//隐藏字体，往左移动20px
span.stop(true,false).animate({opacity:'0',left:'20px'},200);
//显示背景动画
div.stop(true,false).animate({height:'1px',marginTop:'0px',opacity:'1'},300);
div.animate({width:'0px',marginLeft:'0px',opacity:'1'},300);
//显示字体，往右移动20px
span.animate({opacity:'1',left:'0px'},300);
span.css({color:'#777'});
});
});
动画效果是我根据自己的喜好来写的，喜欢的可以自己更改特效。。
