s问题描述：
导航菜单点击菜单项有时不管用，样式修改不了。
解决办法：
import React, { useState,useEffect } from 'react';
import { Link ,useNavigate} from 'react-router-dom';
const Head = () => {
const { Header} = Layout;
const navigateTo = useNavigate();
const [currentSelectedkey, setCurrentSelectedkey] = useState('1'); // 当前选中的菜单项
const locationPath = window.location.hash;
useEffect(() => {
if(locationPath === '#/'){
setCurrentSelectedkey('1');
}else{
setCurrentSelectedkey('2');
}
}, [locationPath]);
const items= [
{
label: (
<Link to="/">首页</Link>
),
key: '1',
},
{
label: (
<Link to="/list">列表页面</Link>
),
key: '2',
},
];
return (
<Menu mode="horizontal" selectedKeys={[currentSelectedkey]} items={items} />
)
