jQuery代码为：
-
//手风琴动画效果 var index7 =0;//定义变量，赋值为0； $(".flash4 ul li").mouseenter(function(){ index7 = $(this).index(); $(this).stop().animate({ 538 },500).siblings("li").stop().animate({ 106 },500); $(".imgCen").eq(index7).css("display","block").siblings(".imgCen").css("display","none"); $("p.bt_2").eq(index7).css("display","block").siblings("p.bt_2").css("display","none"); $(".imgTop img").eq(index7).addClass("tm").siblings(".imgTop img").removeClass("tm"); }); $(".flash4 ul li").mouseleave(function(){ $(this).eq(index7).stop().animate({ 538 },500); $(".imgCen").css("display","none"); $("p.bt_2").css("display","none"); });
