例子中,动画效果是使用jquery的animate函数实现的,请参考:http://keleyi.com/a/bjac/5b62295315de9ace.htm

而用到的Math.floor是取整数,详情请参考:http://keleyi.com/a/bjad/s0ix7ao1.htm

还用到append方法,append() 方法在被选元素的结尾(仍然在内部)插入指定内容,详情请参考http://keleyi.com/a/bjac/0vpch15n.htm

而removeClass方法和addClass方法请参考:http://keleyi.com/a/bjac/e9e40a974de5a902.htm
