今天有人问我这个问题，我就顺便把这个记下来，分享给大伙。
如图，就是图片自己轮播，并且图中中下方的白点也发生变化，图片到哪，白点就到哪，就直接上代码了

var c = null;c = setTimeout(carousel,1000);//开始执行function carousel(){clearTimeout(c);//清除定时器$("#pic"+i).removeClass("active");$("#pic"+(i+1)).addClass("active");i++;$("ol li").removeClass("active");$("ol li:eq("+i+")").addClass("active");if(i>4){$("#pic"+(i-1)).removeClass("active");$("#pic0").addClass("active");i=0;$("ol li:eq("+i+")").addClass("active");}c = setTimeout(carousel,1000); //设定定时器，循环执行 } </script></body>

希望对大家有用
