<div id="rollup" style="overflow:hidden;height:40;color:#ffffff">
<div id="rollup1">
<!-- roll start -->
<!--这里添加滚动的内容，滚动的内容可以是图片，也可以是table包含的html内容-->
<!-- roll end -->
</div>
<div id="rollup2"></div>
</div>
<script>
var speed=30;
rollup2.innerHTML=rollup1.innerHTML;
function Marquee(){
if(rollup2.offsetTop-rollup.scrollTop<=0)
rollup.scrollTop-=rollup1.offsetHeight;
else{
rollup.scrollTop++;
}
}
var MyMar=setInterval(Marquee,speed);
rollup.onmouseover=function() {MyMar=clearInterval(MyMar)}
rollup.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>
<!--向上滚动结束-->

这个就是HTML的功能了，怎么写的
