ASP.NET中利用DataList实现图片无缝滚动
这个问题之前也困扰我，后来解决了，拿出来分享下，以后用也方便，代码很容易看懂，不多说什么了

<div id="demo" style="overflow: hidden; width: 441px; border: 0px">        <table width="441" height="130" border="0" cellpadding="0" cellspacing="0" background="Images/img2/32.jpg">            <tr>                <td align="center" id="demo1" valign="bottom">                    <asp:DataList ID="DataList1" runat="server" RepeatDirection="Horizontal" DataSourceID="ObjectDataSource1">                        <ItemTemplate>                            <table>                                <tr>                                    <td>                                        <asp:ImageButton ID="imgbtnInfo" runat="server" ImageUrl='<%#Eval("Spic") %>' OnClick="imgbtnInfo_Click"                                            CommandArgument='<%#Eval("ID") %>' />                                    </td>                                </tr>                                <tr>                                    <td align="center">                                        <asp:LinkButton ID="lkbtnInfo" CommandArgument='<%#Eval("ID") %>' runat="server"                                            OnClick="lkbtnInfo_Click" CssClass="bb" Text='<%#Eval("Type") %>'></asp:LinkButton>                                    </td>                                </tr>                            </table>                        </ItemTemplate>                    </asp:DataList>                    <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="SelectInfo"                        TypeName="HotelDAL.KeFangServices"></asp:ObjectDataSource>                </td>                <%-- 这一步很重要 --%>                <td id="demo2" align="center" valign="bottom">                </td>            </tr>        </table>    </div>    <script>        //滚动的速度，数值越大速度越慢        var speed = 20        demo2.innerHTML = demo1.innerHTML        //从右至左         function Marquee() {            if (demo1.offsetWidth - demo.scrollLeft <= 0)                demo.scrollLeft = 0            else                demo.scrollLeft++        }        var MyMar = setInterval(Marquee, speed)        demo.onmouseover = function () { clearInterval(MyMar) }        demo.onmouseout = function () { MyMar = setInterval(Marquee, speed) }     </script>
