You can use FSO.js, but be warned that it currently only works in Chrome. Additionally, the folders you create can only really be accessed from within your webapp (for example, you can't choose to write a specific folder on the C drive).
您可以使用FSO.js，但请注意它目前仅适用于 Chrome。此外，您创建的文件夹实际上只能从您的 web 应用程序中访问（例如，您不能选择在 C 驱动器上写入特定文件夹）。

Firstly, You can't really interact with the local system or the server with JavaScript because of security. You can call a server-side script with JavaScript, via AJAX.
首先，由于安全性，您不能真正与本地系统或服务器与 JavaScript 交互。您可以通过 AJAX 使用 JavaScript 调用服务器端脚本。
If you don't care, you can check out Javascript FSO CreateFolder Method
如果你不在乎，你可以查看Javascript FSO CreateFolder Method
JavaScript Example...
JavaScript 示例...
// initialize ActiveXObject and create an object of Scripting.FileSystemObject.
var fso = new ActiveXObject("Scripting.FileSystemObject");
// creates a folder with specified name at the specified location
fso.CreateFolder("C:\Temp\myFolder");
fso = null;
