问题描述

是否可以通过 JavaScript 通过机器的串行端口进行通信?

Is it possible to communicate over a machine's serial port through JavaScript?

我必须编写一个短程序，通过具有 GUI 且跨平台兼容的串行端口向微控制器发送数据，我真的不想使用 Java 的 Swing.

I have to write a short program that sends data to a microcontroller over the serial port that has a GUI and is cross-platform compatible, and I really don't want to use Java's Swing.

推荐答案

JavaScript 本身没有任何内置功能可以让您访问串行端口.但是，各种 JavaScript 引擎(v8、rhino 等)允许您编写自己的自定义原生对象.

JavaScript itself doesn't have any built in functionality to allow you to access the serial port. However, various JavaScript engines (v8, rhino, etc) allow you to write your own custom native objects.

您可能想查看 node.js，这是一个用于 v8 的 JavaScript 库，专注于编写服务器端代码(而不是 Web 浏览器客户端代码).似乎有人已经为此编写了一个串口包:

You might want to check out node.js, which is a JavaScript library for v8 that's focused on writing server-side code (rather than web browser client code). It seems that someone's already written a serialport package for that:
