vue同一个页面可以有多个router-view

参考：https://blog.csdn.net/u011615787/article/details/80075240

参考：https://router.vuejs.org/zh/guide/essentials/named-views.html#%E5%B5%8C%E5%A5%97%E5%91%BD%E5%90%8D%E8%A7%86%E5%9B%BE

分别给router-view定义一个name，默认显示的可以不用定义

自己先在components文件夹内写4个组件，准备放入4个router-viewer标签，我的分别是

containerLeft.vue

containerRight.vue

containerTop.vue

containerBottom.vue

app.vue

<template>
  <div id="app">
    <!-- <img src="./assets/logo.png"> -->
    <!-- <container-Left/> -->
    <router-link to="/HelloWorld" > 222 </router-link>
      <router-view/>
      <router-view name="left" class="area left"/>
      <router-view name="right" class="area right"/>
      <router-view name="logo" class="area "/>
      <router-view name="bottom" class="area bottom"/>
 
  </div>
</template>
 
<script>
import containerLeft from './components/containerLeft.vue'
export default {
  name: 'App',
  components:{
    containerLeft,
  }
}
</script>
 
<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  /* margin-top: 60px; */
}
.area{
  width: 400px;
  height:400px;
  border:1px red soild;
  position: absolute;
  top:20px;
  z-index: 1002;
}
.left{
  left:0px;
  top:100px;
}
.right{
  right: 0px;
}
.bottom{
    top: 90%;
    width: 100%;
    height: 30px;
}
</style>

路由文件router/index.js

核心：

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Veaflet from '@/components/Veaflet'
import containerLeft from '@/components/containerLeft'
import containerRight from '@/components/containerRight'
import containerTop from '@/components/containerTop'
import containerBottom from '@/components/containerBottom'
import lefttree from '@/components/lefttree'
Vue.use(Router)
 
// 创建一个路由器实例
// 并且配置路由规则
const router = new Router({
  routes: [
    {
      path: '/',
      name: 'Veaflet',
      meta:{title:'Veaflet'},
      components:{
        default: Veaflet,
        left:containerLeft,
        right:containerRight,
        logo:containerTop,
        bottom:containerBottom
      }
    },
    {
      path: '/HelloWorld',
      name: 'HelloWorld',
      meta:{title:'HelloWorld'},
      component: HelloWorld
    },
    {
      path: '/containerLeft',
      name: 'containerLeft',
      meta:{title:'containerLeft'},
      component: containerLeft
    },
    {
      path: '/lefttree',
      name: 'lefttree',
      meta:{title:'lefttree'},
      component: lefttree
    }
  ]
 
})
  //修改动态网页标题 beforeEach 导航钩子，路由改变前触发
  router.beforeEach((to,from,next) =>{
    //window.document.title = to.meta.title;
    window.document.title = to.name;
    next();
  })
  router.afterEach((to,from,next) =>{
    window.scrollTo(0,0);
  })
  export default router;

　运行效果如图：
