Javascript实现跑马灯效果

页面html：

 　　　　　　  <div>
                        <div id="imgShows" runat="server" style="padding-bottom: 10px;">
                            <div id="demo" style="overflow: hidden; width: 100%; height: 190px">
                                <table cellspacing="0" cellpadding="0" align="left" border="0" cellspace="0">
                                    <tr>
                                        <td id="demo1" valign="top" runat="server">
                                        </td>
                                        <td id="demo2" valign="top">
                                        </td>
                                    </tr>
                                </table>
                            </div>
                            <script type="text/javascript">
                                var speed = 10
                                var demo = document.getElementById("demo");
                                var demo1 = document.getElementById("demo1");
                                var demo2 = document.getElementById("demo2");
                                demo2.innerHTML = demo1.innerHTML
                                function Marquee() {
                                    if (demo2.offsetWidth - demo.scrollLeft <= 0)
                                        demo.scrollLeft -= demo1.offsetWidth
                                    else {
                                        demo.scrollLeft++
                                    }
                                }
                                var MyMar = setInterval(Marquee, speed)
                                demo.onmouseover = function () { clearInterval(MyMar) }
                                demo.onmouseout = function () { MyMar = setInterval(Marquee, speed) }
                            </script>
                        </div>
                    </div>

cs后台代码：

private void BindPics(int comId)
    {
        List<Model.Pic> pic = DAO.PicDao.GetPics(comId);
        StringBuilder sb = new StringBuilder();
        if (pic == null || pic.Count < 1)
        {
            imgShows.InnerHtml = string.Empty;
            return;
        }
        sb.Append("<table width=\"100%\" border=\"0\" align=\"center\" cellpadding=\"0\"cellspacing=\"10px\"><tr>");
        for (int i = 0; i < pic.Count; i++)
        {
            Model.Pic p = pic[i];
            sb.Append(" <td width=\"200\"><a href=\"" + p.Href + "\"><img src=\"../" + p.Src + "\" border='0' title=\"" + p.Title + "\" alt=\"" + p.Title + "\"></a></td>");
        }
        sb.Append("</tr></table>");
        demo1.InnerHtml = sb.ToString();
    }
