  1.   

    <div id=demo style=overflow:hidden;height:50px>
    <div id=demo1>
    111111111111111<br>
    222222222222222<br>
    333333333333333<br>
    444444444444444<br>
    555555555555555<br>
    </div>
    <div id=demo2></div>
    </div>
    <script>
    var speed=50
    demo2.innerText=demo1.innerText;
    function Marquee(){
    demo.scrollTop++;
    if(demo2.offsetTop<=demo.scrollTop) demo.scrollTop-=demo1.offsetHeight; 
    }
    var Mar=setInterval(Marquee,speed)
    demo.onmouseover=function() {clearInterval(Mar)}
    demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
    </script>你参考一下把
