react怎么实现路由跳转前确认

Prompt示例:https://reactrouter.com/web/example/preventing-transitions Prompt文档:https://reactrouter.com/core/api/Prompt

/** when:是否启用 */ /** message:string | func */ // 示例1  // 示例2  { if (action === 'POP') { console.log("Backing up...") } return location.pathname.startsWith("/app") ? true : `Are you sure you want to go to ${location.pathname}?` }} />

import React, { useEffect, useState } from 'react'; import { Modal } from 'antd'; import { useBoolean } from '@umijs/hooks'; // umi里封装了该组件 // 或者 import { Prompt } from "react-router-dom"; import { useParams, history, Prompt } from 'umi'; import { ExclamationCircleOutlined } from '@ant-design/icons'; import { isEqual } from '@/utils/utils'; import { FormInstance } from 'antd/lib/form'; export default function BaseInfo() { const { id } = useParams<{ id: string }>(); // 保留原始数据 const [orginData, setOrigin] = useState({}); // 修改后的数据 const [modifyData, setModify] = useState({}); // 是否启用Prompt const { state, setTrue, setFalse } = useBoolean(false); // 还原信息 useLoading是自己封装的hooks const [isFetching, fetchInfo] = useLoading(getServiceGroupDetail); useEffect(() => { (async () => { try { if (id !== '0') { const info = await fetchInfo(id); setOrigin({ ...info }); setModify({ ...info }); } } catch (e) { console.error(e); } })(); }, [id]); useEffect(() => { if (isEqual(orginData, modifyData)) { setFalse(); } else { setTrue(); } }, [orginData, modifyData]); const nextStep = (pathname?: string) => { setFalse(); pathname && setTimeout(() => { history.push(pathname); }); }; return ( {/* 这里原来放的Form表单内容 */} {routerWillLeave(state, form, nextStep)} ); } function routerWillLeave( isPrompt: boolean | undefined, formInstance: FormInstance, // 保存，我这个页面是Form表单 nextStep: (pathname?: string) => void ) { return ( 
  { if (!isPrompt) { return true; } Modal.confirm({ icon: , content: '暂未保存您所做的更改，是否保存？', okText: '保存', cancelText: '不保存', onOk() { formInstance?.submit(); nextStep(location.pathname); }, onCancel() { nextStep(location.pathname); } }); return false; }} /> 
 ); }
