我使用 laravel 5.7 和 vue 2.5.7,几周前我刚刚学习了 vue.js,我正在按照高级系列在 youtube 上使用 laravel 和 vue 制作博客。我以为我正确地遵循了视频中的操作,除了我使用的 laravel 和 vue 版本与视频中的版本没有任何不同之外。

这是视频:User CRUD - Build an Advanced Blog/CMS (Episode 12) .

在一集中,我们开始使用 vue,我立即收到如下错误:

[Vue warn]: Property or method "autoPassword" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. (found in Root)

我不明白发生了什么,但这是代码:

app.js

require('./bootstrap');

window.Vue = require('vue');
import Buefy from 'buefy'

Vue.use(Buefy)

var app = new Vue({
el: '#app'
});

layout.blade.php

<!DOCTYPE html>
<html>
<head>
@include('partials.meta-tags')
<title>Dashboard | Bulma CMS</title>
@include('partials.styles')
</head>
<body class="has-navbar-fixed-top">
<div id="app">
<header>
@include('partials.nav.top')
@include('partials.nav.side')
</header>
<main class="has-sidenav-fixed-left">
<div class="p-4">
@yield('content')
</div>
</main>
</div>
<script src="{{ asset('js/app.js') }}"></script>
@yield('scripts')
</body>
</html>

users/create.blade.php

@extends('layout')

@section('content')
<div class="columns">
<div class="column">
<h1 class="title">Manage Users</h1>
<form action="{{ route('users.store') }}" method="POST" autocomplete="off">
@csrf
<div class="field">
<div class="control">
<input type="text" name="name" placeholder="Name" class="input" required />
</div>
</div>
<div class="field">
<div class="control">
<input type="email" name="email" placeholder="Email" class="input" required />
</div>
</div>
<div class="field">
<div class="control">
<input type="password" name="password" placeholder="Password" class="input" :disabled="autoPassword" required />
</div>
</div>
<div class="field">
<div class="control">
<b-checkbox name="auto_password" :checked="true" v-model="autoPassword">Auto Generate Password</b-checkbox>
</div>
</div>
<div class="field">
<div class="control">
<button class="button">Submit</button>
</div>
</div>
</form>
</div>
</div>
@endsection

@section('scripts')
<script>
var app = new Vue({
el: '#app',
data: {
autoPassword: true
}
});
</script>
@endsection

还有一件事,我使用 buefy 复选框

<b-checkbox name="auto_password" :checked="true" v-model="autoPassword">Auto Generate Password</b-checkbox>

我添加了 :checked="true" 来默认检查,如视频中所示,但我所拥有的默认情况下不检查。

谁能帮我吗?

最佳答案

首先你应该知道 :checkedv-bind:checked 的简写,所以你不能绑定(bind)到 true.

删除 : 为:

<b-checkbox name="auto_password" checked="true" v-model="autoPassword">Auto Generate Password</b-checkbox>

其次,创建两个 Vue 实例,一个在 app.js 中,另一个在 users/create.blade.php 中。

您看到的错误是因为 app.js 中的第一个没有 autoPassword

只需从 app.js 中删除这些行即可使其正常工作:

var app = new Vue({
el: '#app'
});
