javascript - Vue.js编译错误: no-unused-vars & no-undef

Question

我目前正在尝试创建一个 Vue.js 组件。当我启动应用程序时出现错误。 错误信息如下图:

<template>
    <div class="hello" id="app">
         <span style="font-size:30px;cursor:pointer;" onclick="openNav()">&#9776;</span>

        <div id="mySidenav" class="sidenav">
            <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a>
            <a href="#">{{name1}}</a>
            <a href="#">{{name2}}</a>
            <a href="#">{{name3}}</a>
            <a href="#">{{name4}}</a>

            <div id="bottom">
                <input v-model="name1" style="margin-left: 25px;max-width: 50%;">
                <input v-model="name2" style="margin-left: 25px;max-width: 50%;">
                <input v-model="name3" style="margin-left: 25px;max-width: 50%;">
                <input v-model="name4" style="margin-left: 25px;max-width: 50%;">

应用程序.vue

Answer 1

这些是来自 eslint 的错误。请参阅https://eslint.org/docs/rules/no-unused-vars和https://eslint.org/docs/rules/no-undef了解详情。

为了消除这些错误，请在初始化应用程序的行之前添加此行

    // eslint-disable-next-line
    var app = new Vue({ 
    // rest of the code 

确保带有 eslint-disable-next-line 的行已被注释。这将告诉 eslint 忽略该行而不是 lint 它。
