请问我的图片滚动代码为何不滚动?

如题,代码如下:<td width="220" height="226" valign="top" background="images/bj_1.gif" align="center">
<DIV id="demo1" style="OVERFLOW: hidden; WIDTH: 220px" align="center">
<TABLE id="Table2" cellSpacing="0" cellPadding="0" border="0">
<TR>
<TD id="demo2">
<table border="0" cellspacing="1" cellpadding="1">
<tr>
<td><img src="images/ryzs_1.gif" width="143" height="107"></td>
</tr>
</table>
</TD>
</TR>
<tr><TD id="demo3" height="1"></TD></tr>
</TABLE>
</DIV>
<SCRIPT language="javascript">
var speed=30
demo3.innerHTML=demo2.innerHTML
function Marquee(){
if(demo3.offsetTop-demo1.scrollTop<=0)
demo1.scrollTop-=demo2.offsetHeight
else{
demo1.scrollTop++
}
}
var MyMar=setInterval(Marquee,speed)
demo1.onmouseover=function() {clearInterval(MyMar)}
demo1.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</SCRIPT>

</td>

代码太乱,重发一下:
<td width="220" height="226" valign="top" background="images/bj_1.gif" align="center">
<DIV id="demo1" style="OVERFLOW: hidden; WIDTH: 220px" align="center">
<TABLE id="Table2" cellSpacing="0" cellPadding="0" border="0">
<TR>
<TD id="demo2">
<table border="0" cellspacing="1" cellpadding="1">
<tr>
<td><img src="images/ryzs_1.gif" width="143" height="107"></td>
</tr>
</table>
</TD>
</TR>
<tr><TD id="demo3" height="1"></TD></tr>
</TABLE>
</DIV>
<SCRIPT language="javascript">
var speed=30
demo3.innerHTML=demo2.innerHTML
function Marquee(){
if(demo3.offsetTop-demo1.scrollTop<=0)
demo1.scrollTop-=demo2.offsetHeight
else{
demo1.scrollTop++
}
}
var MyMar=setInterval(Marquee,speed)
demo1.onmouseover=function() {clearInterval(MyMar)}
demo1.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</SCRIPT>
</td>
先写一个图片位置会增加或减少的函数然后调用下面的函数。后面的数值是毫秒 1000=1秒
setInterval("play()",30);
这里已经写了的啊,大哥,函数名为Marquee
<SCRIPT language="javascript">
var speed=30
demo3.innerHTML=demo2.innerHTML
function Marquee(){
if(demo3.offsetHeight - demo1.scrollTop<=0) //改过
demo1.scrollTop = 0; //改过
else{
demo1.scrollTop++
}
}
var MyMar=setInterval(Marquee,speed)
demo1.onmouseover=function() {clearInterval(MyMar)}
demo1.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</SCRIPT>
lz 这回试试
如果LZ的代码在一个单独的HTML页面中可以的话,也许是如下问题!
1.代码在.NET中不兼容,可以在网上另外找一个
2.页面中有其他JAVASCRIPT代码,屏蔽掉了这段代码的运行,可以去掉其他代码试试
若有其他情况,,一起学习咯!

试了,不行to:dotnet_boy(男人本涩)
1.我现在就用的html页面测试
2.没有其他的JS代码

图片滚动的代码在baidu里面搜索一下,,有很多!
用不着哪里麻烦吧，就直接在<TD>里加marquee就可以了啊
