jQuery仿苏宁易购导航

最近看了些网上的各类导航网站源码，自己学习制作了一个仿苏宁易购的导航栏

jQuery部分代码

 $(function(){
     $(".CategoryTree>ul>li").hover(function(index){
         var obj=$(this).offset();
         var xobj=obj.left+240+"px";
         var yobj=$(this).index()*(-$(this).height()-1)+"px";
         $(this).addClass("selected");
         $(this).children("e:eq(0)").addClass("h2-tit");
         $(this).css("background","#856F62").siblings().css("background","#FFFFFF");
         $(this).children(".tit").children("p").css("color","white");
         $(this).children(".content").css({"left":xobj,"top":yobj}).show();
     },function(){
         $(this).removeClass("selected");
         $(this).children(".tit").removeClass("h2-tit");
         $(this).children(".tit").children("p").css("color","#999");
         $(this).children(".tit").children("span").css("color","black");
         $(this).children(".content").hide();
     })
 })
