思路：首先讀取資料庫中圖片，連結，解說文字等資料，然後將讀取到的資料寫入首頁圖片轉場效果的JS檔案。

下面代碼實現向資料庫中增加 圖片、連結、解說文字等資料 和 產生JS檔案

        ImgUp.SaveAs(Server.MapPath(imgpath));

            HttpContext.Current.Response.End();
            sr.Close();
        }

        // 替換內容         str = str.Replace("$txt$", strtxt);
        str = str.Replace("$pic$", strpic);
        str = str.Replace("$lnk$", strlnk);

        try             sw = new StreamWriter(jsfile, false, code);

}

 

JS檔案模板 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='$txt$' //將被替換的內容（切換圖片的解說文字）
pics='$pic$' //將被替換的內容（切換圖片的地址）
links='$lnk$' //將被替換的內容（連結地址）

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>');

 

辦法三 =================================================================

<script language="javascript" src="js.aspx?classid=2"> </script> 
js.aspx輸出的是js內容就可以了
然後在這個abc.aspx裡讀取資料庫，並產生document.write輸出新聞的語句

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

var focus_width="asdasdasdwer";


document.write(focus_width);
