var ding=10;
var xiao=document.getElementById("xie");
var xiao2=document.getElementById("wen1");
var xiao3=document.getElementById("wen2");
function Xiemiao(){
if(xiao3.offsetHeight-xiao2.scrollTop<=0){
xiao.scrollTop-=xiao3.offsetHeight//demo
}
else{
if(xiao.scrollTop==xiao3.offsetHeight){
xiao.scrollTop=0;
}else{
xiao.scrollTop++;
}
}
}
var MyMar=setInterval(Xiemiao,ding);这样写可以一直滚，不过你得让DIV的高度等于UL的高度
