vue动态路由,三级及以上路由,地址跳转,但是页面不显示

vue动态路由的时候,一级,二级路由都正常展示,但是三级,四级,五级等就只看到地址跳转了,但是页面并没有跳转,原因是共用了一个

import Layout from '@/layout'
import Vue from 'vue'
import Router from 'vue-router'
import db from '@/utils/localstorage'
import {
  Shortcuts
} from 'tinymce'
Vue.use(Router)
const usermenuList = db.get("usermenuList");
let list = [];
console.log(usermenuList);
if (usermenuList.length != undefined) {
  usermenuList.forEach(function(item, index) {
    if (item.parentId == 0) { //一级
      item.component = Layout;
      if (item.children) {//二级
        item.children.forEach(function(item1, index1) {
          if (item1.children) { //三级
            item1.component = {render(c) { return c('router-view')}}
            item1.children.forEach(function(item2, index2) {
              if (item2.children) { //四级
                item2.component = {render(c) { return c('router-view')}}
                item2.children.forEach(function(item3, index3) {
                  if (item3.url) {
                    item3.component = (resolve) => require([`@/views${item3.url}.vue`], resolve);
                  }

                });
              } else {
                if (item2.url) {
                  item2.component = (resolve) => require([`@/views${item2.url}.vue`], resolve);
                }
              }
            });
          } else {
            if (item1.url) {
              item1.component = (resolve) => require([`@/views${item1.url}.vue`], resolve);
            }
          }
        });
      }
    }
    list.push(item);
  });
}


export default {
  section: [
  
    ...list
  ],
}

这种循环希望大家使用递归
