js:
//此处记得引入jquery cdn:<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
var n=2;//由于第一张图是实际是最后1张,是用于从最后一张到第一张过度用,所以n=2,从第二张图开始
$(document).ready(function () {//计时器,用于自动轮播
var timer=setInterval(function () {

},1000)
}
)
//从左向右运动的函数,每次调用向右前进一张图片距离,当到达第四张(也就是给观众看的第三张),则left跳回第一张(也就是和它一样的那张,不过排在开头),由于两张图片一样,可以达到无法察觉的效果
function tonext() {
$('ul').animate({left:-480*n+"px"},function () {
n++;
if(n==4){$('ul').css({left:0});n=1}
})
