无缝滚动是使用JS实现的，其原理很简单将要滚动的Div平铺在父Div中，使用JS控制父DIv的滚动 Object.scrollLeft(向左) = Object.scrollLeft+滚动距离一定的时间间隔滚动一次当滚动距离 = 要滚动DIv的大小的时间，让父Div的 Object.scrollLeft回复到0，开始新一轮的滚动，这样就实现的无缝滚动，依上原理写出实例：<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

由于时间问题，我只给你写一向左滚动效果但我还是建议你不要使用JS控制的无缝滚动，因为在WEB中setInterval和setTimeout都是很耗内存的这样就会降低你的页面执行速度如果你实在要用滚动效果的话，可以考虑用Flash代替
