<script type="text/javascript"> 
var dome=document.getElementById("dome"); //获取节点 
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 关键语句 
function moveTop(){ 
if(dome1.offsetHeight-dome.scrollTop<=0){//判断内容第一次是否循环完了 
dome.scrollTop=0; 
}else{ 
dome.scrollTop++;//否则上移 
} 
} 
var myFunction=setInterval("moveTop()",speed);//设置时间定时 
dome.onmouseover=function(){//鼠标放在区域内停止 
clearInterval(myFunction); 
} 
dome.onmouseout=function(){ 
myFunction=setInterval(moveTop,speed); 
} 
</script>

<!----------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(){
