目的：在用vscode编辑vue和html文件时，用eslint可以同时验证其中的js代码，让其符合js standard和vue的规则。
===安装eslint支持,都安装在项目中===
cmd进入项目目录
npm init -y
npm i -D eslint
npm i -D eslint-plugin-vue
npm i -D eslint-plugin-html
npm i -D eslint-config-standard eslint-plugin-standard eslint-plugin-promise eslint-plugin-import eslint-plugin-node
===vscode安装插件===
vetur，eslint， IntelliSense for CSS class names，css peek
#ctrl+shift+p
#然后eslint c，在当前项目中创建.eslintrc.json文件。
#或者开启optinons选项来引用异地的配置文件
#.eslintrc.json中必须用"html/html-extensions": [".html", ".we"],来限定eslint-plugin-html的作用范围，因为eslint-plugin-html与eslint-plugin-vue有冲突，不限定的话会导致eslint无法识别错误
#同时启用了两个js验证规则：standard, eslint-plugin-vue
===.eslintrc.json===
