思路：首先读取数据库中图片，链接，说明文字等数据，然后将读取到的数据写入首页图片切换效果的JS文件。

下面代码实现向数据库中增加 图片、链接、说明文字等数据 和 生成JS文件

using System.IO;
using System.Text;

public partial class Admin_Slide : System.Web.UI.Page     protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Add_Btn_Click(object sender, EventArgs e) //增加幻灯片,将信息写入数据库         string imgpath;
        imgpath = "../UpLoadFiles/SlideImg/" + ImgUp.FileName;
        ImgUp.SaveAs(Server.MapPath(imgpath));

        MyOleDb mc = new MyOleDb();
        mc.ConnOpen();
        OleDbCommand cmd = new OleDbCommand("insert into SlideImg(lnk,pic,txt) values ('" + linkarea.Text.ToString() + "','" + imgpath + "','" + imgtitle.Text.ToString() + "');", mc.Conn);
        OleDbDataReader rdr = null;
        rdr = cmd.ExecuteReader();
        mc.ConnClose();
    }

    protected void MJS_Btn_Click(object sender, EventArgs e) //生成JS幻灯文件         string jsfile,jstemplete;

        string strlnk, strpic, strtxt;
        strlnk = null;
        strpic = null;
        strtxt = null;

        jsfile = Server.MapPath("~/Js/") + "SlideImg.js";    //JS文件路径
        jstemplete = Server.MapPath("~/Js/") + "JsTemplete.js";    //JS文件模板路径

        deljs(jsfile); //删除JS文件

        MyOleDb mc = new MyOleDb();
        mc.ConnOpen();
        OleDbCommand cmd = new OleDbCommand("select top " + Img_Num.Text.ToString() + " * from SlideImg order by id desc", mc.Conn);
        OleDbDataReader rdr = null;
        rdr = cmd.ExecuteReader();
        while (rdr.Read())             strlnk += rdr["lnk"].ToString() + "|";
            strpic += rdr["pic"].ToString() + "|";
            strtxt += rdr["txt"].ToString() + "|";         mc.ConnClose();

        Encoding code = Encoding.GetEncoding("UTF-8");

        StreamReader sr = null;
        StreamWriter sw = null;
        string str = "";

        try             sr = new StreamReader(jstemplete, code);
            str = sr.ReadToEnd(); // 读取文件         catch (Exception exp)             HttpContext.Current.Response.Write("<script type='text/javascript'>alert('读取模板文件错误！')</script>" + exp.Message);
            HttpContext.Current.Response.End();
            sr.Close();
        }

        // 替换内容         str = str.Replace("$txt$", strtxt);
        str = str.Replace("$pic$", strpic);
        str = str.Replace("$lnk$", strlnk);

        try             sw = new StreamWriter(jsfile, false, code);
            sw.Write(str);
            sw.Flush();         catch (Exception ex)             HttpContext.Current.Response.Write("<script type='text/javascript'>alert('生成JS文件出错！')</script>" + ex.Message);
            HttpContext.Current.Response.End();         finally             sw.Flush();
            sw.Close();
        }

    }

//以下是自定义删除原有JS文件函数

    protected void deljs(string jsfile)         if (File.Exists(jsfile))             File.Delete(jsfile);         else             Response.Write("<script type='text/javascript'>alert('系统中不存在能产生首页切换图片的文件！')</script>");     }
}

JS文件模板 JsTemplete.js

var focus_width=300;
var focus_height=225;
var text_height=18;
var swf_height = focus_height+text_height;
var pics,links,texts;

texts='$txt$' //将被替换的内容（切换图片的说明文字）
pics='$pic$' //将被替换的内容（切换图片的地址）
links='$lnk$' //将被替换的内容（链接地址）

pics=pics.substr(0,pics.length-1);
links=links.substr(0,links.length-1);
texts=texts.substr(0,texts.length-1);

var fv="pics="+pics+"&links="+links+"&texts="+texts+"&borderwidth="+focus_width+"&borderheight="+focus_height+"&textheight="+text_height;

document.write('<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0" width="'+ focus_width +'" height="'+ swf_height +'">');
document.write('<param name="allowScriptAccess" value="sameDomain"><param name="movie" value="../Plugin/slide.swf"><param name="quality" value="high"><param name="bgcolor" value="#E5ECF4">');
document.write('<param name="menu" value="false"><param name=wmode value="opaque">');
document.write('<param name="FlashVars" value="pics='+pics+'&links='+links+'&texts='+texts+'&borderwidth='+focus_width+'&borderheight='+focus_height+'&textheight='+text_height+'">');
document.write('<embed src="pixviewer.swf" wmode="opaque" FlashVars="pics='+pics+'&links='+links+'&texts='+texts+'&borderwidth='+focus_width+'&borderheight='+focus_height+'&textheight='+text_height+'" menu="false" bgcolor="#009900" quality="high" width="'+ focus_width +'" height="'+ focus_height +'" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />');
document.write('</object>');

办法三 =================================================================

<script language="javascript" src="js.aspx?classid=2"> </script> 
js.aspx输出的是js内容就可以了
然后在这个abc.aspx里读取数据库，并生成document.write输出新闻的语句

<%@ Page Language="C#" AutoEventWireup="true" %>

var focus_width="asdasdasdwer";


document.write(focus_width);
