右键格式化文档或者ctrl + s保存 html不换行

1.安装两个插件①vetur ②Prettier - Code formatter

2.在vetur的settings.json中设置

配置ctrl+s触发格式化去除分号和单引号；配置格式化js换行；配置解决html属性换行

将最后一部分的设置，修改成上图即可

    // // 当保存代码的时候，会自动格式化"editor.formatOnSave": true,// 不添加分号"prettier.semi": false,// 使用单引号"prettier.singleQuote": true,// 解决Vue的属性换行问题"vetur.format.defaultFormatter.html": "js-beautify-html","vetur.format.defaultFormatter.js": "vscode-typescript",//在配置了默认格式后 这个需要打开 否则js格式化会换行"vetur.format.defaultFormatterOptions": {"js-beautify-html": {"wrap_attributes": "auto"},"prettyhtml": {"printWidth": 1000,"singleQuote": false,"wrapAttributes": false,"sortAttributes": false}},

3.如果右键格式化或者ctrl+s，没有触发效果，在配置一下格式化的默认方式：看图，选择Vetur为默认值。

4.这是我自己mac上的settings.json完整配置：
