vue-router addRoute将子路由添加到指定路由下

router.addRoute()可以向vue路由中动态的添加路由信息，但，路由存在多层级关系，例如，最开始的路由是这样的：

{
    path: '/',
    name: 'layout',
    component: resolve => require(['../layout'], resolve),
    meta: {
        title: '',
        handleStatus: 2
    },
    children: [
        //用户信息
        {
            path: '/memberInfo-index',
            component: resolve => require(['../views/memberInfo/index'], resolve),
            meta: {
                title: '欢迎页',
                handleStatus: 3,
                mainTitle: 1,
                memberInfo: true,
                permission: false,
                isMyFileEnabled: false
            }
        },
   ]
}

若，想在name为layout的这个路由下加一条子路由，可以这样实现

import router from "./router";
import theCollaborativeroup from "@/views/workingplatform/the-collaborative-group/index";
router.addRoute(
    "layout",
    {
        path: '/group',
        component: theCollaborativeGroup,
        meta: {
            title: "协同组",
            handlestatus: 9,
            mainTitle: 2,
            permission: false,
            isTaskGroupEnabled: false
       }
   }
)

addRoute的第一个参数接收一个字符串，就是告诉它要插入到那个路由(要写name属性)
