     <div  id="ntice2"></div> 
    </div>

 

 

<script language="javascript" type ="text/javascript"> 
var speed=50
ntice2.innerHTML=ntice1.innerHTML 
function Marquee(){ 
if(ntice2.offsetTop-ntice.scrollTop<=0) 
ntice.scrollTop-=ntice1.offsetHeight 
else{ 
ntice.scrollTop++ 
} 
} 
var MyMar=setInterval(Marquee,speed) 
ntice.onmouseover=function() {clearInterval(MyMar)} 
ntice.onmouseout=function() {MyMar=setInterval(Marquee,speed)} 
</script>

 

2.左滚动

 

 

<div  id="demo" style="overflow:hidden;width:850px;height:100px;">

             demo2.innerHTML=demo1.innerHTML
             function Marquee(){
             if(demo2.offsetWidth-demo.scrollLeft<=0)
             demo.scrollLeft-=demo1.offsetWidth
             else{
             demo.scrollLeft++
             }
