给你个例子，不明白的话直接问我就行< script type="text/javascript">var speed=40;var FGDemo=document.getElementById('demo');var FGDemo1=document.getElementById('demo1');var FGDemo2=document.getElementById('demo2');FGDemo2.innerHTML=FGDemo1.innerHTMLfunction Marquee1(){if(FGDemo.scrollLeft<=0)FGDemo.scrollLeft+=FGDemo2.offsetWidthelse{FGDemo.scrollLeft--}}var MyMar1=setInterval(Marquee1,speed)FGDemo.onmouseover=function() {clearInterval(MyMar1)}FGDemo.onmouseout=function() {MyMar1=setInterval(Marquee1,speed)}< /script>

这个好办，我们的客户网站里面有滚动的例子
