分享两个无缝滚动的例子，第一个比较全面，可以设置一下效果，具体大家配置就可以，第二个比较死板
有延迟停留的加载，并且一行一样的滚动
var atea=document.getElementById("box");
var iLiHeight=24;//滚动高度
area.innerHTML+=atea.innerHTML;//重新创建一个滚动替代
var speed=50;
var delay=2000;
var time=null;
function startMove( ){
atea.scrollTop++;
time=setInterVal("scrollUp()",speed);
}
function scrollUp(){
if(area.scrollTop%iLiHeight==0){ //刚好满足一次滚动高度，就停止一下，在滚动
clearInterVal(time);
setTimeOut("startMove()",delay);
}else{
area.scrollTop++;
if(area.scrollTop>=area.scrollHeight/2){
atea.scrollTop=0;
}
}
}
setTimeOut("startMove()",2000)
