在Visual Studio Code中运行JavaScript

是否有一种方法来执行JavaScript和显示使用Visual Studio代码的结果?

例如，一个脚本文件包含:

console.log('hello world');

我假设Node.js是需要的，但不知道如何做到这一点?

通过Visual Studio Code，我指的是来自微软的新代码编辑器不是用Visual Studio编写的代码。

过程

*(前言)

步骤如下: 根据我的记忆，没有严格测试步骤…(可能会错过一些东西?) 以后的版本可能会有一些不同的变化事物的自动设置(例如:环境路径)可能是不同的在Win10

运行纯js

download & install Vscode download & install Node.js from the the offical website, eg: in G:\nodejs\node.exe open Vscode -> open your workspace folder eg: MyTestSpace -> create a new file call eg: test.js write a code console.log('-----test-----'); in test.js go to the Run and Debug panel (ctrl+shift+d) > Run drop down list at the top > Add Config (MyTestSpace) > a launch.json should be auto generated for you > at the auto-completetion popup > select Node.js: Launch Program > auto complete config fill in > rename the program to the path where your test.js locate your launch.json should look something like this:: { "version": "0.2.0", "configurations": [ { "type": "node", "request": "launch", "name": "Launch Program", "program": "${workspaceFolder}/test.js", }, ], } go back to the Run drop down list > select Launch Program (MyTestSpace) > click the Run button in your Debug Console should see the following:: G:\nodejs\node.exe .\test.js -----test----- a graph for demo naming might be different (just a ugly rough draft for demo [[(just try to post an answer wrote with little effort...)]]) (ignore unnecessary staff...)

运行js & html(简要介绍)

have a eg: main_test.html file, with a <script> tag refer to the test.js in the Run drop down list > add config > select Chrome > auto complete launch.json > change path to main_test.html eg: { "type": "chrome", "request": "launch", "name": "Open main_test.html", "file": "h:\\Book\\debug\\LXPI\\OEBPS\\lib_new2\\libNt\\crossFileHtse\\build_HighlightTypeset_ReadHtse\\main_test.html", }, select that chrome launch config > Run > html is opened up in your browser & console log printed

在VS代码中遵循这些步骤。[在Windows操作系统下执行]

创建新文件在里面写javascript代码保存文件为filename.js 转到调试菜单点击“开始调试” 或者直接按F5

为了简单地运行代码并在控制台上显示输出，您可以创建一个任务并执行它，就像@canerbalci提到的那样。

这样做的缺点是，你只能得到输出，仅此而已。

我真正喜欢做的是能够调试代码，让我们说我试图解决一个小算法或尝试一个新的ES6功能，我运行它，有一些可疑的东西，我可以在VSC中调试它。

因此，我没有为它创建一个任务，而是修改了.vscode/launch。Json文件，如下所示:

{
"version": "0.2.0",
"configurations": [
    {
        "name": "Launch",
        "type": "node",
        "request": "launch",
        "program": "${file}",
        "stopOnEntry": true,
        "args": [],
        "cwd": "${fileDirname}",
        "runtimeExecutable": null,
        "runtimeArgs": [
            "--nolazy"
        ],
        "env": {
            "NODE_ENV": "development"
        },
        "externalConsole": false,
        "sourceMaps": false,
        "outDir": null
    }
]
}

这将在VSC的调试器中启动您当前所在的文件。它设置在启动时停止。

要启动它，在要调试的文件中按F5键。

只需安装nodemon并运行
