Wo可能不是我
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
