实现datalist的走马灯效果(滚动)

横向滚动

<table id=”Table1″ align=”center” style=”width: 650px; height: 100px” cellspacing=”0″
        cellpadding=”0″ border=”0″>
        <tr>
            <td>
                <div id=”demo” style=”overflow: hidden; width: 650px; height: 100px” align=”center”
                    designtimedragdrop=”134″>
                    <table>
                        <tr>
                            <td id=”demo1″ valign=”middle”>
                                <asp:DataList ID=”DataList1″ runat=”server” Width=”650px”

RepeatDirection=”Horizontal”>
                                    <ItemTemplate>
                                        <table id=”Table2″ cellspacing=”0″ cellpadding=”0″ width=”102″

border=”0″>
                                            <tr>
                                                <td>
                                                    <img  src=’<%#DataBinder.Eval

(Container.DataItem,”tp”)%>’ border=”0″></td>
                                            </tr>
                                        </table>
                                    </ItemTemplate>
                                </asp:DataList>
                            </td>
                            <td id=”demo2″ valign=”top”>
                            </td>
                        </tr>
                    </table>
                </div>
            </td>
        </tr>
    </table>

    <script type=”text/javascript”>
    var  Picspeed=10; ///滚动速度 越小越快
    demo2.innerHTML=demo1.innerHTML;
    function Marquee1()
    {
        if(demo2.offsetWidth-demo.scrollLeft   <=0)
            demo.scrollLeft-=demo1.offsetWidth
        else
