Nuxt 嵌套路由nuxt-child组件用法(父子页面组件的传值)

<template>
 <div>
 <h2>父组件的页面的内容</h2>
 <ul>
 <!-- 进行切换子页面，写法同vue.js -->
 <li><nuxt-link to='/parent/child'>child</nuxt-link></li>
 <li><nuxt-link to='/parent/child2'>child2</nuxt-link></li>
 </ul>
 <hr>
 <div class="box">
 <p>嵌套子页面内容区</p>
 <!-- <nuxt-child>标签在父页面组件中相当于是子页面组件的占位符；嵌套中这个不可少 -->
 <nuxt-child keep-alive :foobar="123"></nuxt-child>
