可利用該語法來處理：new ActiveXObject("Scripting.FileSystemObject")


看到有些人不推這種方式，但是應用於內網，所以安全性設定可以統一佈署，這個問題倒是不難處理。

 

 

 

 

Check 上傳檔案大小 (內有說明優缺點及詳細範例，擷錄部份文章如下)

使用時會跳出下列警告視窗，不是很方便

js到底能不能判断客户端上传文件的大小

http://bbs.csdn.net/topics/280043968

function getFileSize(filepath) { //這段可正常運作！
   if(window.ActiveXObject){
       var fso=new ActiveXObject("Scripting.FileSystemObject");
       var file=fso.GetFile(filepath);
       filesize=file.size;
    }
}

The FileSystemObject Object

The FileSystemObject object is used to access the file system on a server.

This object can manipulate files, folders, and directory paths. It is also possible to retrieve file system information with this object.

The following code creates a text file (c:\test.txt) and then writes some text to the file:

<%
dim fs,fname
set fs=Server.CreateObject("Scripting.FileSystemObject")
set fname=fs.CreateTextFile("c:\test.txt",true)
fname.WriteLine("Hello World!")
fname.Close
set fname=nothing
set fs=nothing
%>
