1背景：

多级路由跳转到三级页面，面包屑显示，三级菜单隐藏

2问题：

页面跳转路径显示正确，但是页面显示的内容错误

3解决：

给页面children添加 <router-view />

path: 'manager',
      // component: () => import('@/views/taskManager/index'), // 可单独创建一个容器页面，或者下面这句代码也可，两种方法
      component: {
        render(h) {
          return h('router-view')
        }
      },
      name: 'taskManagerList',
      redirect: { name: 'taskManagerLists' },
      meta: { title: '任务管理', icon: 'documentation', roles: ['admin'] },

实现效果

import Layout from '@/layout'

const taskManagerRouter = {
  path: '/task',
  component: Layout,
