非基于Web的JavaScript，调用C ++函数 [英] Non Web-Based JavaScript, call C++ function

问题描述

嘿大家好我正在试图弄清楚如何从javascript调用C ++函数。我看到的每个地方，我只是得到基于网络的答案，这对我没有帮助。我正在研究一个在机器运行时运行javascript的程序，我需要这个脚本来调用C ++函数，但是无法弄清楚如何。有帮助吗？即使是最基本的答案，例如如何获得Hello world等。运行C ++函数就足够了。谢谢！

解决方案

JavaScript在哪里运行？在浏览器中或（如node.js）在控制台中？


如果JS在浏览器中运行，则不能直接调用C ++函数。你必须进行往返并调用一个为你运行该函数的服务器脚本。

它在控制台中运行。一旦机器开始运行，它就会执行一个处理信息的xxx.js文件。计算机上没有迹象表明发生了任何事情。我只需要这个.js来调用一些C ++函数。

然后它取决于你的JS主机提供的文件系统API。


但即使这样，你也只能调用一个运行C ++的app /脚本。 JS无法直接调用另一种语言的函数。

Hey everyone. I''m trying to figure out how to call a C++ function from javascript. Everywhere I look, I''m just getting web-based answers and that won''t help me. I''m working on a program that runs javascript while a machine is running, and I need this script to call a C++ function along the way, but can''t figure out how. Any help? Even the most basic answer such as how to get a "Hello world" C++ funtion to run will be sufficient. Thanks!

解决方案

where does the JavaScript run? in a browser or (like node.js) in the console?

if the JS runs in a browser, you can?t call a C++ function directly. you have to take a roundtrip and call a server script that runs the function for you.

It runs in the console. Once a machine starts running, it executes a xxx.js file which processes the information. There is no indication on the computer that anything is happening at all. I just need this .js to call on some C++ functions.

then it depends on the File System API that your JS host provides.

but even then, you can only call an app/script that runs the C++ for you. there is no way for JS to directly call another language’s function.
