<!---------多复制<li>标签就行了------这里就不多写了---------->
</div>
<div id="dome2"></div>
</div>
</div>
<!----------防止html没有加载完，把javascript代码写在下面---------->
<script type="text/javascript">
var dome=document.getElementById("dome");
var dome1=document.getElementById("dome1");
var dome2=document.getElementById("dome2");
var speed=50;//设置向上轮动的速度
dome2.innerHTML=dome1.innerHTML;//复制节点
function moveTop(){
      
      
if(dome1.offsetHeight-dome.scrollTop<=0){
      
      
dome.scrollTop=0;
}else{
      
      
dome.scrollTop++;
}
}
var myFunction=setInterval("moveTop()",speed);
dome.onmouseover=function(){
      
      
clearInterval(myFunction);
}
dome.onmouseout=function(){
      
      
myFunction=setInterval(moveTop,speed);
}
</script>
