常用标签解释

通过router动态加载组件

注册路由

const routes = [
  {
    path: '/',
    name: '导航1',
    component: App,
    children:[
      {
        path: '/PageOne',
        name: '页面1',
        component: PageOne
      },
      {
        path: '/PageTwo',
        name: '页面2',
        component: PageTwo
      },
    ]
  },
  {
    path: '/navigation',
    name: '导航2',
    component: App,
    children:[
      {
        path: '/PageThree',
        name: '页面3',
        component: PageThree
      },
      {
        path: '/PageFour',
        name: '页面4',
        component: PageFour
      },
    ]
  },
]

前端代码

<el-aside width="200px" style="background-color: rgb(238, 241, 246)">
        <el-menu>
          <el-submenu v-for="(item,index) in $router.options.routes" :index="index+''">
            <template solt="title"><i class="el-icon-setting"></i>{{item.name}}</template>
            <el-menu-item v-for="item2 in item.children">{{item2.name}}</el-menu-item>
          </el-submenu>
        </el-menu>
      </el-aside>

设置动态路由导航

上面做完后,会发现出现套娃

解决方法:
不能直接在App.vue上写代码
App.vue代码改成如下:

<template>
  <div id="app">
    <router-view></router-view>
    </div>
</template>

<style>
.el-header {
  background-color: #B3C0D1;
  color: #333;
  line-height: 60px;
}

.el-aside {
  color: #333;
}
</style>

<script>
export default {
  data() {
    const item = {
      date: '2016-05-02',
      name: '王小虎',
      address: '上海市普陀区金沙江路 1518 弄'
    };
    return {
      tableData: Array(20).fill(item)
    }
  }
};
</script>

核心代码抽成一个组件,同时也要使用router-view标签 去渲染子标签
将组件注册后即可解决问题

事件绑定

实现点击页面即可切换页面操作
el-menu标签添加router属性
<el-menu router="router">
绑定el-menu-item的index值,该值就是跳转路径
<el-menu-item v-for="item2 in item.children" :index="item2.path">{{item2.name}}</el-menu-item>

<template>
  <el-container style="height: 500px; border: 1px solid #eee">
    <el-aside width="200px" style="background-color: rgb(238, 241, 246)">
      <el-menu router="router">
