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。

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

其他回答

在Visual Studio Code中运行javascript有很多方法。

如果您使用Node,那么我建议使用VSC中的标准调试器。

我通常创建一个虚拟文件,比如test.js,在那里我做外部测试。

在存放代码的文件夹中,创建名为“”的文件夹。然后创建一个名为launch。json的文件

在此文件中粘贴以下内容并保存。现在您有两个选项来测试您的代码。

当你选择“Nodemon Test File”时,你需要把你的代码放在Test .js中进行测试。

要安装nodemon以及更多关于如何在VSC中调试nodemon的信息,我建议阅读这篇文章,它更详细地解释了发布的第二部分。json文件和如何调试在ExpressJS。

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Nodemon Test File",
            "runtimeExecutable": "nodemon",
            "program": "${workspaceFolder}/test.js",
            "restart": true,
            "console": "integratedTerminal",
            "internalConsoleOptions": "neverOpen"
        },
        {
            "type": "node",
            "request": "attach",
            "name": "Node: Nodemon",
            "processId": "${command:PickProcess}",
            "restart": true,
            "protocol": "inspector",
        },
    ]
}

只需在谷歌上搜索“Mozilla javascript参考”。打开第一个链接(developer.mozilla),然后打开该页中的任何链接。它提供了“试试”的示例代码,你可以删除和编写和测试你自己的代码。简单。无需VS-Code:-)

我面对这个确切的问题,当我第一次开始使用扩展代码运行器VS Code

你需要做的是在用户设置中设置node.js路径

您需要设置路径,因为您安装它在您的Windows机器。

我的是“C:\\Program Files\\nodejs\\node.exe\”

因为我的文件目录名中有一个空格

请看下面的图片。我未能在第一次运行代码,因为我在路径名称中犯了一个错误

希望这对你有所帮助。

当然,你的问题帮助了我,因为我也来这里寻求帮助,在我的VS CODE中运行JS

只需安装nodemon并运行

nodemon your_file.js

在vs code终端上。
