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。

集成终端的快捷方式是ctrl + ',然后键入node <filename>。

或者,您可以创建一个任务。这是唯一的代码在我的tasks.json:

{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "0.1.0",
"command": "node",
"isShellCommand": true,
"args": ["${file}"],
"showOutput": "always"
}

从这里创建一个捷径。这是我的keybindings.json:

// Place your key bindings in this file to overwrite the defaults
[
{   "key": "cmd+r",
"command": "workbench.action.tasks.runTask"
},
{   "key": "cmd+e",
"command": "workbench.action.output.toggleOutput"
}
]

这将在命令面板中打开“运行”,但你仍然需要用鼠标键入或选择你想要运行的任务,在这种情况下是节点。第二个快捷键切换输出面板,它已经有一个快捷键,但这些键彼此相邻,更容易使用。

这很简单,当你在VS Code中创建一个新文件并运行它时,如果你还没有配置文件,它会为你创建一个,你唯一需要设置的是“program”值,并将其设置为你的主JS文件的路径,如下所示:

{
    "version": "0.1.0",
    // List of configurations. Add new configurations or edit existing ones.  
    // ONLY "node" and "mono" are supported, change "type" to switch.
    // ABSOLUTE paths are required for no folder workspaces.
    "configurations": [
        {
            // Name of configuration; appears in the launch configuration drop down menu.
            "name": "Launch",
            // Type of configuration. Possible values: "node", "mono".
            "type": "node",
            // ABSOLUTE path to the program.
            "program": "C:\\test.js", //HERE YOU PLACE THE MAIN JS FILE
            // Automatically stop program after launch.
            "stopOnEntry": false,
            // Command line arguments passed to the program.
            "args": [],
            // ABSOLUTE path to the working directory of the program being debugged. Default is the directory of the program.
            "cwd": "",
            // ABSOLUTE path to the runtime executable to be used. Default is the runtime executable on the PATH.
            "runtimeExecutable": null,
            // Optional arguments passed to the runtime executable.
            "runtimeArgs": [],
            // Environment variables passed to the program.
            "env": { },
            // Use JavaScript source maps (if they exist).
            "sourceMaps": false,
            // If JavaScript source maps are enabled, the generated code is expected in this directory.
            "outDir": null
        }, 
        {
            "name": "Attach",
            "type": "node",
            // TCP/IP address. Default is "localhost".
            "address": "localhost",
            // Port to attach to.
            "port": 5858,
            "sourceMaps": false
        }
    ]
}

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

另一种方法是打开终端ctrl+ '执行节点。现在您有了一个活动的节点REPL。您现在可以将您的文件或选定的文本发送到终端。为了做到这一点,打开VSCode命令面板(F1或ctrl+shift+p)并执行>在活动终端运行选定的文本或>在活动终端运行活动文件。

如果在执行代码之前需要一个干净的REPL,则必须重新启动节点REPL。这是在终端中使用节点REPL ctrl+c ctrl+c退出它,并键入node开始新的。

您可能可以将命令面板命令按键绑定到您希望的任何键。

node应该安装在您的路径中

我很惊讶居然没有人提到这一点:

只需在VS Code中打开有问题的.js文件,切换到“调试控制台”选项卡,点击左侧导航栏中的调试按钮,然后点击运行图标(播放按钮)!

需要安装nodejs !

只需安装nodemon并运行

nodemon your_file.js

在vs code终端上。
