刀片困境中的 Laravel vue 和 js答案

【问题标题】：Laravel vue and js in blade dilemma刀片困境中的 Laravel vue 和 js

【问题描述】：

猜这是一个愚蠢的问题，但我不知道解决方案。我想将一个 vue 组件和 js 文件加载到刀片视图中。当我放

<script src="{{ asset('js/app.js') }}"></script>
<script src="{{ asset('js/selectize_settings.js') }}"></script>

它加载 selectize_settings.js 文件，但不加载 vue。当我推迟时

<script src="{{ asset('js/app.js') }}" defer></script>
<script src="{{ asset('js/selectize_settings.js') }}"></script>

它加载 vue 组件，但不加载 selectize_settings.js（ReferenceError: $ 未定义）。我知道这是因为当我加载 selectize_settings.js 时，jquery 还没有通过 app.js 加载。

app.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.
 */

require('./bootstrap');

window.Vue = require('vue');
import BootstrapVue from 'bootstrap-vue'

Vue.use(BootstrapVue)
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue/dist/bootstrap-vue.css'
import 'selectize/dist/css/selectize.default.css'

window.$ = window.jQuery = require('jquery')
require('selectize');

/**
 * 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.
 */

Vue.component('example-component', require('./components/ExampleComponent.vue'));

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

test.blade.php

<!doctype html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">

            <example-component></example-component>
        </div>
    </div>
</body>
</html>

selectize_settings.js

$( document ).ready(function() {
    $('#select-beast').selectize({
        create: true,
        sortField: {
            field: 'text',
            direction: 'asc'
        },
        dropdownParent: 'body'
    });
});

ExampleComponent.vue

<template>
    <div class="container">
        <div class="row justify-content-center">
            <div class="col-md-8">
                <div class="card">
                    <div class="card-header">Example Component</div>

                    <div class="card-body">
                        I'm an example component.
                    </div>
                </div>
            </div>
        </div>
    </div>
</template>

<script>
    export default {
        mounted() {
            console.log('Component mounted.')
        }
    }
</script>

我希望有人可以提供帮助。问候！

【问题讨论】：

您是否仅将 jQuery 用于选择插件？也许你想看看这个插件，它基本上是用 VueJS 制作的 selectize.js：github.com/isneezy/vue-selectize

标签： javascript laravel vue.js

【解决方案1】：

在你的 app.js 中试试这个

//...
global.$ = global.jQuery = require('jquery');
//...

你也可以删除 defer attr

<script src="{{ asset('js/app.js') }}"></script>

【讨论】：

谢谢回答。它仍然给我 Uncaught ReferenceError: $ is not defined 错误

【解决方案2】：

试试这个：

Vue.component('example-component', require('./components/ExampleComponent.vue').default);

【讨论】：

谢谢回答。不幸的是仍然给出 [Vue warn]: Cannot find element: #app error when I don't use defer

【解决方案3】：

好的，当你把 defer 放到 js 文件中时它也可以工作！

<script src="{{ asset('js/app.js') }}" defer></script>
<script src="{{ asset('js/selectize_settings.js') }}" defer></script>
