laravel - Vuejs 在 laravel 的视图中效果不佳

问题描述

我试图直接在房间的视图中使用 vuejs，但我无法让它工作。附代码

Prueba.blade.php

@extends('layouts.app')

@section('content')
<div id="demox">
    <h1>Pruebas</h1>
    <h3 v-text="title"></h3>
</div>


@endsection

@section('scripts')

<script>

document.addEventListener("DOMContentLoaded", function() {
    const demo = new Vue({
        el: '#demox',
        data:function(){
            return {
                title: "Titulo en VUEJS"
            }
        },
        mounted() {
            console.log('cargado')
        },
    })
  });

</script>

@endsection

布局.app.blade.php

应用程序.js

/**
 * First we will load all of this project's JavaScript dependencies which
 * includes Vue and other libraries. It is a great starting point when
 * building robust, powerful web applications using Vue and Laravel.
 */
import VueSweetalert2 from 'vue-sweetalert2';


require('./bootstrap');

window.Vue = require('vue');

/**
 * The following block of code may be used to automatically register your
 * Vue components. It will recursively scan this directory for the Vue
 * components and automatically register them with their "basename".
 *
 * Eg. ./components/ExampleComponent.vue -> <example-component></example-component>
 */

// const files = require.context('./', true, /\.vue$/i)
// files.keys().map(key => Vue.component(key.split('/').pop().split('.')[0], files(key).default))
Vue.use(VueSweetalert2);
Vue.component('example-component', require('./components/ExampleComponent.vue').default);
Vue.component('eliminar-registro', require('./components/EliminarRegistro.vue').default);
Vue.component('modal-encuestas', require('./components/ModalEncuestas.vue').default);
Vue.component('abrir-modal', require('./components/AbrirModal.vue').default);
Vue.component('ejemplo-prueba', require('./components/EjemploPrueba.vue').default);


/**
 * Next, we will create a fresh Vue application instance and attach it to
 * the page. Then, you may begin adding components to this application
 * or customize the JavaScript scaffolding to fit your unique needs.
 */

// const app = new Vue({
//     el: '#app',
// });

错误：

app.js:42027 [Vue 警告]：“数据”选项应该是一个在组件定义中返回每个实例值的函数。

app.js:42027 [Vue 警告]：属性或方法“标题”未在实例上定义，但在渲染期间被引用。通过初始化该属性，确保此属性是反应性的，无论是在数据选项中，还是对于基于类的组件。请参阅：https ://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties。* *

会发生什么？谢谢
