jQuery 借助插件Lavalamp实现导航条动态美化效果

借助插件 Lavalamp实现导航条动态显示效果，以前用animate来实现，效果不是很好
复制代码代码如下:

.nav {
width:650px;
height:100px;
float:left;
position: relative;
}
.nav li {
width:auto;
min-width:40px;
line-height:100px;
padding:0 15px;
margin:0 10px 0 0;
color:#000;
font-size:14px;
text-align:center;
float:left;
}
.nav li.back {
background: #86bf40;
-moz-border-radius: 5px;
-webkit-border-radius: 5px;
line-height: 2;
width: 40px;
height: 100px;
z-index: 1;
position: absolute;
margin-top: 0px;
margin-left:5px;
}
.nav li a {
color: #000;
z-index: 2;
font-variant: small-caps;
text-decoration: none;
position: relative;
margin: auto 10px;
}

复制代码代码如下:
(function($) {
$.fn.lavaLamp = function(o) {
o = $.extend({ fx: "linear", speed: 500, click: function(){} }, o || {});

return this.each(function() {
var me = $(this),
noop = function(el){

},
$back = $('

').appendTo(me),
$li = $("li", this),
curr = $("li.current", this)[0] || $($li[0]).addClass("current")[0];

$li.not(".back").hover(function() { move(this);});

$(".nav li:eq(0) a").css("color","#FFF");
function setCurr(el) {alert(el.offsetWidth);
$back.css({ "left": el.offsetLeft+"px", "width": el.offsetWidth+"px" });
curr = el;

};

function move(el) {
$back.each(function() {
$.dequeue(this, "fx"); }
).animate({
width: el.offsetWidth-40,
left: el.offsetLeft
}, o.speed, o.fx,function(){
var a0=$(".nav li:eq(0) a");
var a1=$(".nav li:eq(1) a");
var a2=$(".nav li:eq(2) a");
var a3=$(".nav li:eq(3) a");
var a4=$(".nav li:eq(4) a");
var a5=$(".nav li:eq(5) a");
if(el.offsetLeft==0){
$(".nav li:eq(0) a").css("color","#FFF");
a1.css("color","#000");
a2.css("color","#000");
a3.css("color","#000");
a4.css("color","#000");
