vue

描述：子路由，也叫路由嵌套，采用在children后跟路由数组来实现，数组里和其他配置路由基本相同，需要配置path和component，然后在相应部分添加<router-view/>来展现子页面信息，相当于嵌入iframe。

Home.vue

<template>
    <div class="hello">
        <h1>{{ msg }}</h1>
        <!-- 添加子路由导航 -->
        <p>导航 ：
            <router-link to="/home">首页</router-link> | 
            <router-link to="/home/one">-子页面1</router-link> |
            <router-link to="/home/two">-子页面2</router-link>
        </p>
        <!-- 子页面展示部分 -->
        <router-view/>
    </div>
</template>

<script>
export default {
    name: 'Home',
    data () {
        return {
            msg: 'Home Page!'
        }
    }
}
</script>

<style scoped>
</style>

One.vue /Two.vue

<template>
  <div class="hello">
    <h1>{{ msg }}</h1>
  </div>
</template>

<script>
export default {
  name: "One",
  data() {
    return {
      msg: "Welcome to One!"
    };
  }
};
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
h1,
h2 {
  font-weight: normal;
}
ul {
  list-style-type: none;
  padding: 0;
}
li {
  display: inline-block;
  margin: 0 10px;
}
a {
  color: #42b983;
}
</style>

index.js

import Vue from 'vue'
import Router from 'vue-router'
import Home from '@/components/Home'
import One from '@/components/One' 
import Two from '@/components/Two'

Vue.use(Router)

export default new Router({
    routes: [
    {
        path: '/', // 默认页面重定向到主页
        redirect: '/home'
    },
    {
        path: '/home', // 主页路由
        name: 'Home',
        component: Home,
        children:[ // 嵌套子路由
            {
                path:'one', // 子页面1
                component:One
            },
            {
                path:'two', // 子页面2
                component:Two
            },
        ]
    }
    ]
})
