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

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);
