如果这是由于浏览器的安全性问题，那么应该采用哪种替代方式呢？

If this is due to browser security issue then what should be the alternate way to do this?

推荐答案

某些浏览器具有防止JavaScript知道文件本地完整路径的安全功能。这是有道理的 - 作为客户端，您不希望服务器知道您的本地机器的文件系统。如果所有浏览器都这样做，这将是很好的。

Some browsers have a security feature that prevents JavaScript from knowing your file's local full path. It makes sense - as a client, you don't want the server to know your local machine's filesystem. It would be nice if all browsers did this.
