¥🔧 Options

json

{
    "vue/no-unused-vars": ["error", {
        "ignorePattern": "^_"
    }]
}

ignorePattern ...当你的 v-for 指令或范围属性的定义与你的 ignorePattern 正则表达式匹配时禁用报告。默认 null，不会忽略任何内容
¥ignorePattern ... disables reporting when your definitions of v-for directives or scope attributes match your ignorePattern Regular expression. default null, will ignore nothing

¥🚀 Suggestion

当你的 ignorePattern 设置为 ^_ 时，我们可以提供一个建议，在你的变量中添加前缀 _，这样就不会再出现 eslint 错误
¥When your ignorePattern set to ^_, we could provide a suggestion which add a prefix_ to your variable and no more eslint error
