VUE成分在幼体中未显示

Vue component not showing up in laravel(VUE成分在幼体中未显示)

问题描述

我的VUE组件没有显示，我看不到哪里出错了，我希望另一双眼睛能指出我哪里出错了。 我正在运行NPM Run Watch，并且已清除缓存。

我的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');

/**
 * 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('table-draggable', require('./components/TableDraggable.vue'));
Vue.component('category-index', require('./components/CategoryIndex.vue'));
Vue.component('active-checkbox', require('./components/ActiveCheckbox.vue'));
Vue.component('supplier-code-selection', require('./components/SupplierCodeSelection.vue'));

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

我的供应商代码选择.vue

     <template>
            <div class="container">
                <div class="row justify-content-center">
                    <div class="col-md-8">
                        <div class="card">
                            <div class="card-header">Supplier Code Selection 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>

VUE应显示的我的页面

<div id="app">
    <supplier-code-selection></supplier-code-selection>
</div>

我的控制台中也出现此错误

[Vue warn]: Unknown custom element: <supplier-code-selection> - did you register the component correctly? For recursive components, make sure to provide the "name" option.

推荐答案

您的代码是正确的，但您似乎忘记在Html中包含加载css/js文件。

将此添加到<head>：

<link rel="stylesheet" href="{{ mix('css/app.css') }}" />
<script defer src="{{ mix('js/app.js') }}"></script>

---

我还建议使用npm run hot(或yarn hot)，这将增加热代码重新加载。
