还有另一个预览HTML文件的扩展，叫做Live Preview。我喜欢它胜过这个答案中链接的“活动服务器”的几个原因。

无需启动服务器，预览图标集成到VS代码中(与标记预览相同) 预览在VS代码中以分屏视图打开(尽管在浏览器中打开的选项是可用的) 由微软开发(开发VS代码的同一家公司) 目前“实时预览”在“预览”中，只需要完善:-)

您现在可以在浏览器中安装一个扩展视图。我在chrome的windows上测试了它，它是工作的。

Vscode版本:1.10.2

对于Mac，设置你的任务。将. json(在.vscode文件夹中)文件内容拷贝到以下文件中，并使用SHFT+COMMAND+B打开。

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Chrome Preview",
            "type": "shell",
            "command": "open -a /Applications/Google\\ Chrome.app test.html",
            "problemMatcher": [],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

CTRL+SHIFT+P将调出命令面板。 当然，这取决于你在运行什么。例如，在ASP.net应用程序中，你可以输入: >kestrel，然后打开web浏览器，输入localhost:(你的端口在这里)。

如果你输入>，它会显示show和run命令

或者在您使用HTML的情况下，我认为打开命令面板后的F5应该打开调试器。

VSCode任务-通过应用程序包标识符打开(仅限macOS)。

      "command": "open",

Windows -打开默认浏览器-在VS Code v 1.1.0上测试

回答既打开一个特定的文件(名称是硬编码)或打开任何其他文件。

步骤:

Use ctrl + shift + p (or F1) to open the Command Palette. Type in Tasks: Configure Task or on older versions Configure Task Runner. Selecting it will open the tasks.json file. Delete the script displayed and replace it by the following: { "version": "0.1.0", "command": "explorer", "windows": { "command": "explorer.exe" }, "args": ["test.html"] } Remember to change the "args" section of the tasks.json file to the name of your file. This will always open that specific file when you hit F5. You may also set the this to open whichever file you have open at the time by using ["${file}"] as the value for "args". Note that the $ goes outside the {...}, so ["{$file}"] is incorrect. Save the file. Switch back to your html file (in this example it's "text.html"), and press ctrl + shift + b to view your page in your Web Browser.
