react中(reactv18)+router(v6)js获取router实例及技巧

`

/**

  • 获取react-router实例对象,在js中跳转页面
    */
    // useEffect 的函数会在组件渲染到屏幕之后执行
    // useLayoutEffect则是在DOM结构更新后、渲染前执行,相当于有一个防抖效果(不推荐)
    import { useState, useEffect } from 'react'
    import { createBrowserHistory, createHashHistory } from 'history'
    import { Router } from 'react-router-dom'

// 1. history
// export const history = createBrowserHistory();
// 2. hash
// == 创建路由实例对象 =》作用:js中使用跳转页面 ==
export const history = createHashHistory()
// == 函数组件 => 作用:包裹根组件,注册history
export const HistoryRouter = ({ history, children }) => {

const [state, setState] = useState({
action: history.action,
location: history.location
})

useEffect(() => {
history.listen(setState)
}, [history])

return <Router children={children} navigator={history} {...state} />
}

记得在index.js入口使用实例包裹而不是import { HashRouter } from "react-router-dom"中的HashRouter
import { HistoryRouter, history } from '@/router/history'
HistoryRouter history={history}
