Help!谁帮我把这段化境的脚本改成JavaScript的?

[ywiori27]

脚本如下:
<!--#include FILE="upload_5xsoft.inc"-->
<%
dim upload,file,formName,formPath,iCount
set upload=new upload_5xSoft ''建立上传对象

response.write upload.Version&"<br><br>" ''显示上传类的版本

if upload.form("filepath")="" then ''得到上传目录
HtmEnd "请输入要上传至的目录!"
set upload=nothing
response.end
else
formPath=upload.form("filepath")
''在目录后加(/)
if right(formPath,1)<>"/" then formPath=formPath&"/"
end if

iCount=0
for each formName in upload.file ''列出所有上传了的文件
set file=upload.file(formName) ''生成一个文件对象
if file.FileSize>0 then ''如果 FileSize > 0 说明有文件数据
file.SaveAs Server.mappath(formPath&file.FileName) ''保存文件
response.write file.FilePath&file.FileName&" ("&file.FileSize&") => "&formPath&File.FileName&" 成功!<br>"
iCount=iCount+1
end if
set file=nothing
next
set upload=nothing ''删除此对象
Htmend iCount&" 个文件上传结束!"

sub HtmEnd(Msg)
set upload=nothing
response.write "<br>"&Msg&" [<a href=""javascript:history.back();"">返回</a>]</body></html>"
response.end
end sub
%>

下面是我改写的一部分:
<%@LANGUAGE="JAVASCRIPT" CODEPAGE="936"%>
<!--#include file="upload_5xsoft.inc"-->
<%
var upload;
var upload = new upload_5xSoft(); //建立上传对象

Response.Write(upload.Version);+"<br><br>"; //显示双传类版本
%>

但执行到 " var upload = new upload_5xSoft(); //建立上传对象 " 的时候就提示'upload_5xSoft' 未定义 .

求JavaScript代码!

-----------------
因为upload_5xSoft这是用VBScript写的类,
当然不能直接在JavaScript中直接调用啊.

你得改upload_5xSoft的VBScript->JavaScript
改写问题主要出在JavaScript对字节进算的能力很差,不像VBScript有leftB,RightB,lenB
这样专字节运算的函数..
