推荐答案

答案是:不能！

原因是，这些Angular代码只是在客户端计算机上执行的Javascript代码.出于多种原因，例如，不允许Javascript编程语言访问客户端计算机的文件系统.

The reason is, those Angular codes are simply Javascript codes which are executed on the client computer. For many reasons, the Javascript programming language is unable to, let's say, is not allowed to access the file system of the client computer.

只能使用NodeJS(使用Javascript框架，它允许您使用Javascript编程语言在服务器端进行编程)来使用Javascript访问文件系统.

Accessing the file system using Javascript is only possible with NodeJS - a javascript framework which allows you programming on the server-side using Javascript programming language.
