VS Code团队现在有一个官方扩展，叫做“Live Preview”

快速设置:

安装“实时预览”扩展从微软。 从工作空间打开html文件，当前工作空间之外的文件无法工作。 执行命令> Live Preview: Show Preview(外部浏览器)

还有一个命令用于在内部浏览器中启动它。您可能还需要从扩展设置中更改默认端口，以防它已经在您的系统上使用。

发布说明:https://code.visualstudio.com/updates/v1_59#_live-preview

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。

下面是如何在Windows的多个浏览器中运行它

{
 "version": "0.1.0",
 "command": "cmd",
 "args": ["/C"],
 "isShellCommand": true,
 "showOutput": "always",
 "suppressTaskName": true,
 "tasks": [
     {   
         "taskName": "Chrome",
         "args": ["start chrome -incognito \"${file}\""]
     },
     {   
         "taskName": "Firefox",
         "args": ["start firefox -private-window \"${file}\""]
     },
     {   
         "taskName": "Edge",
         "args": ["${file}"]
     }   
    ]
}

注意，我没有为edge在args中输入任何东西，因为edge是我的默认浏览器，只是给了它文件名。

编辑:你也不需要-incognito或-private-window…只有我，我喜欢在私人窗口看

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.

下面是Mac OSx的2.0.0版本:

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
    {
      "label": "echo",
      "type": "shell",
      "command": "echo Hello"
    },
    {
      "label":"chrome",
      "type":"process",
      "command":"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome",
      "args": [
        "${file}"
      ]
    }
  ]
}

下面是一个2.0.0版本的当前文档在Chrome带键盘快捷方式:

tasks.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Chrome",
            "type": "process",
            "command": "chrome.exe",
            "windows": {
                "command": "C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe"
            },
            "args": [
                "${file}"
            ],
            "problemMatcher": []
        }
    ]
}

快捷键。json:

{
    "key": "ctrl+g",
    "command": "workbench.action.tasks.runTask",
    "args": "Chrome"
}
