jquery 代码

<script >

    $(function() { 

         var currentIndex;//当前索引值

         var picTotal = $("img").length;//当前照片数量

         var ToDisplayPicNumber = 0;//当前自动轮播索引值

         $("li").each(function() {//获取li并且绑定点击事件

             $(this).click(function(){

                 displayPic(this);

                 ToDisplayPicNumber = $(this).index();

             })

         })

         function displayPic(obj){

             currentIndex = $(obj).index();

             //ToDisplayPicNumber = currentIndex;

             $(obj).siblings().removeClass("currentNum").end().addClass("currentNum");

            $("#lunbo-img").children().hide();

             $("#lunbo-img img").eq(currentIndex).fadeIn();

        }

        var l = setInterval(function(){//定时器

            autoDisplayPic();

        },2000);

        function autoDisplayPic(){//轮播代码

            ToDisplayPicNumber = (ToDisplayPicNumber + 1) % picTotal;

            $("li").eq(ToDisplayPicNumber).trigger("click");

        }

        $("img").mouseover(function() {//鼠标移入图片清除定时器

            clearInterval(l);

        }).mouseout(function() {

            l = setInterval(function(){//鼠标移出图片恢复定时器
