概述：

我们开发react引入antd之后导航栏会出现刷新不选中、不展开二级导航栏、页面js点击之后不选中最新tab、只能展开一个二级tab之类的问题。那么我们一起来把问题给解决了

问题描述

其实问题这些问题差不多就是一个问题，就是Menu没有刷新选中的状态

实现代码

import React, { useState ,useEffect } from 'react';
import {DesktopOutlined,FileOutlined,PieChartOutlined,TeamOutlined,UserOutlined,
} from '@ant-design/icons';
import {Menu} from 'antd';
import {useNavigate ,useLocation} from "react-router-dom"
import type { MenuProps } from 'antd';type MenuItem = Required<MenuProps>['items'][number];function getItem(label: React.ReactNode,key: React.Key,icon?: React.ReactNode,children?: MenuItem[],
): MenuItem {return {key,icon,children,label,} as MenuItem;
}const items: MenuItem[] = [getItem('首页', '/index', <PieChartOutlined />),getItem('店铺', '/store', <DesktopOutlined />),getItem('商品', 'goods', <UserOutlined />, [getItem('平台商品', '/goods/list'),getItem('平台添加', '/goods/edit'),getItem('平台商品', '/goods/page301'),getItem('平台品牌', '48'),getItem('自营商品', '55'),getItem('自营品牌', '56'),getItem('标配商品', '57'),]),getItem('订单', 'page4', <UserOutlined />, [getItem('采购单', '/page3/page301'),getItem('客户订单', '4'),getItem('订单列表', '50'),getItem('售后列表', '53'),]),getItem('财务', 'page5', <UserOutlined />, [getItem('结算单列表', '/page3/page301'),getItem('我的钱包', '40'),getItem('支付密码设置', '52'),]),getItem('会员', 'page6', <UserOutlined />, [getItem('邀请会员', '/page3/page301'),getItem('邀请用户列表', '41'),]),getItem('数据', 'page7', <UserOutlined />, [getItem('销售统计', '/page3/page301'),getItem('售后统计', '42'),getItem('商品统计', '43'),getItem('操作日记', '44'),]),getItem('广告管理', 'page8', <UserOutlined />, [getItem('广告位列表', '/page3/page301'),getItem('广告列表', '422'),]),
];const Comp: React.FC = () => {const navigateTo = useNavigate();const currentRouter =  useLocation();const [selectedKeys, setSelectedKeys] = useState(currentRouter.pathname);//当前选中项const [stateOpenKeys, setStateOpenKeys] = useState(firstOpenkey);//默认二级导航栏useEffect(() => {//组件动态更新setSelectedKeys(currentRouter.pathname)})const menuClick = (e:{key:string})=>{console.log(e.key)//在js里面跳转到对应的路由  编程式导航跳转，利用到一个hooknavigateTo(e.key);}function firstOpenkey(): string{for(let i=0;i<items.length;i++){//判断找到情况if(items[i]!['children']&&items[i]!['children'].length>0 && items[i]!['children'].find(findkey)){return items[i]!.key as string;}}return ''}function findkey(obj:{key:string}){return obj.key===currentRouter.pathname}const handleonOpenChange =(keys:string[])=>{//展开和回收的事件setStateOpenKeys(keys[keys.length-1])}return(<Menu theme="dark" defaultSelectedKeys={[currentRouter.pathname]} selectedKeys={[selectedKeys]}mode="inline" items={items} onClick={menuClick} onOpenChange={handleonOpenChange}openKeys={[stateOpenKeys]}/>)
}export default Comp;

这样一来就可以通过useNavigate来跳转页会刷新当前的状态，展开相应的二级ta
