左右滚动 js：

var speed3=25//速度数值越大速度越慢
demo2.innerHTML = demo1.innerHTML

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

var MyMar = setInterval(Marquee, speed3)

demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout = function() { MyMar = setInterval(Marquee, speed3) }
