Vue模板未渲染(控制台中无错误)

Question

我目前正在尝试编写多个.vue文件，稍后我可以使用Laravel的Blade Syntax将其用作模板标签。

我写下了在我的app.js中使用vue的必要行，注册了我的组件以便使用我文件的语法。

但是，我运行npm run dev成功且没有错误。然而，我的Vue没有被渲染&& Chrome Dev控制台没有显示错误(没有检测到Vue.js)

app.js

require('./bootstrap');

// import Vue from 'vue'
// import VueRouter from 'vue-router'
// import TriviaGame from './components/TriviaGame.vue'
// import Dashboard from './components/Dashboard.vue';

Window.vue = require('vue');


// Vue.use(VueRouter)

// Vue.config.productionTip = false
Vue.component('trivia-game', require('./components/TriviaGame.vue')).default;
Vue.component('dashboard', require('./components/Dashboard.vue')).default;

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


// const routes = [
//     { path: '/', component: Dashboard },
//     { path: '/trivia', component: TriviaGame }
// ]

// const router = new VueRouter({
//     mode: 'history',
//     routes
// })

// new Vue({
//     router,
//     render: h => h(Dashboard)
// }).$mount('#app')

你在头部的app.js在dom解析之前就被执行了(还没有#app )。

要么把它移到身体的底部

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

或添加延时

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

或者在dom内容加载事件中添加vue代码。

window.addEventListener("load", function(event) {
    new Vue({...})
});
