你好，我在首页的导航栏加入了自下向上滚动的代码，代码如下：<div id="demo" style="margin: 30px auto; width: 250px; height: 483px; overflow: hidden">
<div id="demo1"><img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/1.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/2.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/3.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/4.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/5.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/6.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/7.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/8.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/9.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/10.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/11.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/12.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/13.jpg" /> <img border="0" alt="" src="/e/upload/s1/fck/image/2013-05/14.jpg" /></div>
<div id="demo2"></div>
<script>
var speed=50
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></div>
但我首页的“校园风光”向左滚动不动了，这里是调用系统自带的“图动滚动”，不知什么原因，请楼主帮忙解决，谢谢！网址：www.hzthzx.com
