1.前一節已經安裝了vue-router(npm install vue-router --save),現在就來使用一下

1）先在App.vue元件中配置路由出口

<template>
  <div id="app">
    <div class="container">
      <app-header></app-header>
    </div>
    <div class="container">
<!-- 路由匹配到的元件將渲染在這裡 -->
      <router-view></router-view>
    </div>
  </div>
</template>
 

2) 配置main.js檔案

import Vue from 'vue'
import App from './App.vue'
import VueRouter from 'vue-router'
import { routes } from './router'

Vue.use(VueRouter);

const router = new VueRouter({
  routes,
})

new Vue({
  el: '#app',
  router,
  render: h => h(App)
})

3）配置 router.js檔案

import Home from './components/Home'
import Coupon from './components/Marketing/Coupon'
import Questionnaire from './components/Marketing/Questionnaire'
import Analysis from './components/Marketing/Analysis'

export const routes = [
    { path: '/', component: Home},
    { path: '/coupon', component: Coupon},
    { path: '/questionnaire', component: Questionnaire},
    { path: '/analysis', component: Analysis},
    { path: '*', redirect: '/' }
]
 

這裡最後一條配置是當訪問的 url 沒有路由與之匹配的話就跳轉到主頁

4) 修改Header.vue 元件

<template>
    <header>
        <nav class="navbar navbar-expand-lg navbar-light bg-light">
            <router-link class="py-2" to="/">
                <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="d-block mx-auto"><circle cx="12" cy="12" r="10"></circle><line x1="14.31" y1="8" x2="20.05" y2="17.94"></line><line x1="9.69" y1="8" x2="21.17" y2="8"></line><line x1="7.38" y1="12" x2="13.12" y2="2.06"></line><line x1="9.69" y1="16" x2="3.95" y2="6.06"></line><line x1="14.31" y1="16" x2="2.83" y2="16"></line><line x1="16.62" y1="12" x2="10.88" y2="21.94"></line></svg>
            </router-link>
            <router-link to="/" class="navbar-brand">主頁</router-link>
            <ul class="navbar-nav">
                <li><router-link to="/coupon" class="nav-link">優惠券管理</router-link></li>
                <li><router-link to="/questionnaire" class="nav-link">問卷管理</router-link></li>
                <li><router-link to="/analysis" class="nav-link">資料統計</router-link></li>
            </ul>
        </nav>
    </header>
</template>
 

然後 npm run dev 執行就OK了！
