<script src="http://cdn.bootcss.com/jquery/2.1.0/jquery.js"></script>
<script>
$(function(){
$("ul li:not(:last)").hover(function(){
$("#huaBlock").stop(); //停止正在运行的动画
var curliWidth=$(this).outerWidth(),curleft=$(this).offset().left-$(this).parent().offset().left; //当前li的偏移量减去当前ul的偏移量就是li距离ul的距离
// alert("curleft:"+curleft);
$("#huaBlock").animate({"width":curliWidth,"left":curleft},500);
},function(){
$("#huaBlock").stop();
$("#huaBlock").animate({"width":98,"left": 5},200);
});
});
</script>
