Javascript实现跑马灯效果的简单实例

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();  }

数据库表：

USE [Enterprise]GO/****** 对象: Table [dbo].[Pics]  脚本日期: 03/17/2011 19:26:27 ******/SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOSET ANSI_PADDING ONGOCREATE TABLE [dbo].[Pics]( [Id] [int] IDENTITY(1,1) NOT NULL, [ComId] [int] NOT NULL, [Title] [varchar](50) COLLATE Chinese_PRC_CI_AS NULL, [Href] [varchar](255) COLLATE Chinese_PRC_CI_AS NULL, [Src] [varchar](255) COLLATE Chinese_PRC_CI_AS NOT NULL,PRIMARY KEY CLUSTERED ( [Id] ASC)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]) ON [PRIMARY]GOSET ANSI_PADDING OFF

实体类：

public class Pic  {    public int Id { set; get; }    public int ComId { set; get; }    public Model.CompanyModel CompanyModel { set; get; }    public string Title { set; get; }    public string Src { set; get; }    public string Href { set; get; }  }
