JavaScript / JQuery与SerialPort / COM1进行通信 [英] JavaScript/JQuery communicate with SerialPort/COM1

问题描述

有可能强迫任何来自例如Javascript / JQuery到任何串行comport？！

谷歌无法回答这个问题..但无论如何它应该是可能的.. env是在我的情况下的Firefox。 b
$ b 理念/知识非常值得欢迎。

亲切的录音带

然而，这可以在JavaScript中使用Node.js完成。它作为一个进程而不是在浏览器窗口中运行，并可以访问文件系统。具体来说，已经有一个用于串行通信的npm模块（节点库）： https://github.com/voodootikigod / node-serialport

或者，您可以随时启动本地Web服务器（通过node.js，php，rails等）。 Web服务器可以访问文件系统，因此应该可以访问串行端口。

希望这有助于。

is it possible to force any communication from e.g. Javascript/JQuery to any serial comport?!

google is not able to answer that question.. but anyway it should be possible.. env is firefox in my case..

ideas/knowledge is very welcome.

kindly tape

解决方案

Yes you can, but not with a typical browser. Browsers are sandboxed to not have access to the local file system (except cookies) so that malicious sites can't read from / write to your hard drive. As far as I know there is no way to override this behvior (short of writing your own browser).

However, this can be done in JavaScript using Node.js. It runs as a process rather than in a browser window and can access the file system. Specifically, there is already an npm module (node library) for serial communication: https://github.com/voodootikigod/node-serialport

Alternatively, you could always just spin up a local web server (via node.js, php, rails, etc). Web servers can access file systems, and therefore should be able to access serial ports.

Hope this helps.
