專案結構

main.js

import Vue from 'vue';
import App from './App.vue';

//引入公共的scss   注意：建立專案的時候必須用scss
import './assets/css/basic.scss';   

import router from './router/router.js';

//4、掛載路由

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

app.vue

<template>


  <div id="app"> 

    <header class="header">

      <router-link to="/home">首頁</router-link>
      <router-link to="/news">新聞</router-link>
       <router-link to="/user">使用者</router-link>
    </header>

    <hr>
    <router-view></router-view>

  </div>
</template>
<script>

   export 
 
default {     
      data () { 
        return {
         
         msg:'你好vue'
        }
      }
     
    }
</script>
<style lang="scss">

  .header{


    height:4.4rem;

    background:#000;

    color:#fff;

    line-height:4.4rem;

    text-align:center;

    a{
      color:#fff;

      padding:
 
0 2rem

    }
  }
</style>

router.js

import Vue from 'vue';

//配置路由
import VueRouter from 'vue-router';
Vue.use(VueRouter);


//1.建立元件
import Home from '../components/Home.vue';
import News from '../components/News.vue';
import User from '../components/User.vue';


//2.配置路由   注意：名字

const routes = [
    { path: 
 
'/home', component: Home },
    { path: '/news', component: News, name: 'news' },

    { path: '/user', component: User },


    { path: '*', redirect: '/home' }   /*預設跳轉路由*/
]


//3.例項化VueRouter  注意：名字

const router = new VueRouter({
    mode: 'history',   /*hash模式改為history*/
    routes // （縮寫）相當於 routes: routes
})


//5 <router-view></router-view> 放在 App.vue

export default router;

Home.vue

<template>
    <!-- 所有的內容要被根節點包含起來 -->
    <div id="home">    
       我是首頁元件
    
        
       
    </div>
</template>


<script>
    export default{
        data(){
            return {               
               msg:'我是一個home元件',
                value1: null,
             
            }
        }
    }

</script>

<style lang="scss" scoped>
    
</style>
