js 图片滚动

左右跑
<div align="center">
<div id=demo style=overflow:hidden;height:33;width:50;>
<table align=left cellpadding=0 cellspace=0 border=0>
<tr>
<td id=demo1 valign=top>
显示的内容放在这里 </td>
<td id=demo2 valign=top></td>
</tr>
</table>
</div>
<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
function Marquee(){
if(demo2.offsetWidth-demo.scrollLeft<=0)
demo.scrollLeft-=demo1.offsetWidth
else{
demo.scrollLeft++
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script></div>


注：显示的内容必须要比 DIV (demo) 的宽度要宽
