Typescript+React封装路由拦截组件

需求：离开切换页面检测是否保存，点击确认跳转相应路由，取消则留在本页

 react-router取消了路由守卫，自带组件Prompt可以进行路由拦截,后面借助antd的Modal封装成弹窗组件

import { Modal } from 'antd'
import * as React from 'react'
import { Prompt, useHistory } from 'react-router'


interface IRouterPromptProps {
  isBlock: boolean
  title?: string
  content?: string
  onOk?: () => void
}




/**
 * 路由拦截组件
 * 监听页面跳转是否需要保存信息
 */
export const RouterPrompt = React.memo((props: IRouterPromptProps) => {
  const history = useHistory()
  const [isBlock, setIsBlock] = React.useState(props.isBlock)




  React.useEffect(() => {
    setIsBlock(props.isBlock)
  }, [props.isBlock])




  const handleClick = (location: any, action: string, type: string) => {
    if (type === 'ok') {
      setTimeout(() => {
        if (action === 'POP') {
          history.goBack()
        } else if (action === 'PUSH') {
          history.push(location)
        } else {
          history.replace(location)
        }
      }, 100)
      setIsBlock(false)
      // console.log('我已确认')
    }
  }




  return (
    <Prompt
      when={isBlock}
      message={(location, action) => {
        Modal.confirm({
          title: props.title ? props.title : '提醒',
          content: props.content ? props.content : '修改的内容尚未保存，是否继续',
          okText: '确定',
          cancelText: '取消',
          onOk: () => handleClick(location, action, 'ok'),
          onCancel: () => handleClick(location, action, 'cancel')
        })
        return false
      }}
    />
  )
})




export default RouterPrompt

使用：在需要拦截的页面导入，在任一处使用

import RouterPrompt from 'yourroute/RouterPrompt'
<RouterPrompt isBlock title="提醒" content="修改的内容尚未保存，是否继续" />
