向上滚动的效果
插入代码：
<div id=demo style=overflow:hidden;height:150;width:90;background:#214984;color:#ffffff>
<div id=demo1>
<!-- 定义图片 -->
<img src="images/logo_1.gif">
<img src="images/logo/flashempire.gif">
<img src="images/logo.gif">
<img src="images/logo/5dmedia.gif">
<img src="images/logo/macromedia.gif">
<img src="images/logo/sucaiw.gif">
<img src="images/logo/blueieda.gif">
<img src="images/logo/htmlcn.gif">
<img src="images/logo/fwcn.gif">
</div>
<div id=demo2></div>
</div>
<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
function Marquee(){
if(demo2.offsetTop-demo.scrollTop<=0)
demo.scrollTop-=demo1.offsetHeight
else{
demo.scrollTop++
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>

制作向下滚动的效果：
将上面“制作向上滚动的效果”中的黑色字体Js部分替换成：
<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
demo.scrollTop=demo.scrollHeight
function Marquee(){
if(demo1.offsetTop-demo.scrollTop>=0)
demo.scrollTop+=demo2.offsetHeight
else{
demo.scrollTop--
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>

　　制作向左滚动的效果：
<div id=demo style=overflow:hidden;height:33;width:500;background:#214984;color:#ffffff>
<table align=left cellpadding=0 cellspace=0 border=0>
<tr>
<td id=demo1 valign=top><img src="images/logo_1.gif"><img src="images/logo/flashempire.gif"><img src="images/logo.gif"><img src="images/logo/5dmedia.gif"><img src="images/logo/macromedia.gif"><img src="images/logo/sucaiw.gif"><img src="images/logo/blueieda.gif"><img src="images/logo/htmlcn.gif"><img src="images/logo/fwcn.gif">
</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>

　　制作向右滚动的效果：
　　将上面“制作向左滚动的效果”中的黑色字体Js部分替换成：
<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
demo.scrollLeft=demo.scrollWidth
function Marquee(){
if(demo.scrollLeft<=0)
demo.scrollLeft+=demo2.offsetWidth
else{
demo.scrollLeft--
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>
