[html]
<div id="demo" style="overflow: hidden; width: 441px; border: 0px">
        <table width="441" height="130" border="0" cellpadding="0" cellspacing="0" background="Images/img2/32.jpg">

    <script>
        //滚动的速度,数值越大速度越慢
        var speed = 20
        demo2.innerHTML = demo1.innerHTML
        //从右至左 
        function Marquee() {
            if (demo1.offsetWidth - demo.scrollLeft <= 0)
                demo.scrollLeft = 0
            else
                demo.scrollLeft++
        }  www.jb51.net
        var MyMar = setInterval(Marquee, speed)
        demo.onmouseover = function () { clearInterval(MyMar) }
        demo.onmouseout = function () { MyMar = setInterval(Marquee, speed) } 
    </script>
