Question

我使用vue cli webpack生成一个应用程序。现在我正在尝试将一些数据加载到视图中而没有成功。这是当前状态的代码：

main.js

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'

import BootstrapVue from 'bootstrap-vue'
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue/dist/bootstrap-vue.css'

Vue.config.productionTip = false
Vue.use(BootstrapVue)

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>',
  data: {
    exchanges: [
      {name: 'gdax', price: 1450},
      {name: 'bitfinex', price: 1525}
    ]
  }
})

App.vue

<template>

  <div id="app" class="container">
    <h1>Arb Bot</h1>
    <router-view/>
  </div>
</template>

<script>
  export default {
    name: 'App'
  }
</script>

<style>
  #app {
    font-family: 'Avenir', Helvetica, Arial, sans-serif;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    color: #2c3e50;
    margin-top: 60px;
  }
</style>

路由/ index.js

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Opportunities from '@/components/Opportunities'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      name: 'HelloWorld',
      component: HelloWorld
    },
    {
      path: '/opportunities',
      name: 'Opportunities',
      component: Opportunities
    }
  ]
})

Opportunities.vue

<template>
  <div>
    <h2>Bitcoin prices</h2>
    <table>
      <tr>
        <td>Exchange</td><td>Price</td>
      </tr>
      <tr v-for="exchange in exchanges" :key="exchange.name">
        <td>{{ exchange.name }}</td><td>{{ exchange.price }}</td>
      </tr>
    </table>
  </div>
</template>

视图正常呈现，但data未加载，因此具有交换名称的表行未显示在浏览器中。

如何将数据正确加载到视图中并打印表格？

由于

Answer 1

el: '#app',

指ID = app的元素，在您的情况下缺少。

你可以通过给表id = app

来修复它

<table id="app">

如何在Vue.js应用
