Datalist 实现无间断滚动

网上找了一段无间隔滚动的代码
但是在datalist下面就不好用了 怎么回事呢
<%@ Register Src="RunPic.ascx" TagName="RunPic" TagPrefix="uc1" %>
<script language="JavaScript">
<!--
var Marquee1 = "A_101128cb798";
var Marquee2 = "BA_101128cb798";
var Container = "CA_101128cb798";
var MarqueeSpeed = 10;

//-->
</script>


<asp:DataList id="TopNewslist" runat="server" Width="400" RepeatDirection="Horizontal">
<ItemTemplate>
<div align="center" style="overflow:hidden;width:400" id="CA_101128cb798">
<TABLE cellPadding=0 align=left border=0 cellspace="0">

<TR>
<TD><A href='ShowNews.aspx?ID=<%# DataBinder.Eval(Container.DataItem,"ID").ToString() %>'>
<IMG height=150 width=120 src='VodPic/<%# DataBinder.Eval(Container.DataItem,"img_url").ToString() %>' ></A>
</TD>
</TR>

</TABLE>

</div>
</ItemTemplate>
</asp:DataList>



<script language="JavaScript">
<!--
//以下不要修改
document.getElementById(Marquee2).innerHTML=document.getElementById(Marquee1).innerHTML
function Marquee(){
if(document.getElementById(Container).scrollLeft>=document.getElementById(Marquee1).scrollWidth)
document.getElementById(Container).scrollLeft=0
else
document.getElementById(Container).scrollLeft++
}
var DA_101128cb798 = window.setInterval(Marquee,MarqueeSpeed)
document.getElementById(Container).onmouseover=function() {window.clearInterval(DA_101128cb798)}
document.getElementById(Container).onmouseout=function() {DA_101128cb798 = window.setInterval(Marquee,MarqueeSpeed)}
-->
</script>
