Javascript实现跑马灯效果的简单实例_javascript技巧

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 ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE 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]

GO
SET 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; }
  }
