$(function(){

var demo = document.getElementById("demo");
var demo1 = document.getElementById("demo1");
var demo2 = document.getElementById("demo2");
demo2.innerHTML=demo1.innerHTML //克隆demo1为demo2
function marquee(){
if(demo2.offsetHeight-demo.scrollTop<=0){ //当滚动至demo1与demo2交界时
demo.scrollTop-=demo1.offsetHeight //demo跳到最顶端
}else{
demo.scrollTop++;
}
}
var MyMark = setInterval(marquee,speed)
demo.onmouseover=function() {clearInterval(MyMark)}
