react-router中嵌套的子组件拿location对象的问题

Question

比如说一个页面有个modal组件，modal组件里面的内容写在子组件里面(ModalDetail),在这个组件里面拿不到this.props.location，求解答，除了从父组件传进去和通过window对象拿，还有什么方法

react-router v4之前的版本，有一个叫做withRouter的高阶组件。你在定义自己的modal组件时包一层即可。v4版本暂时没有用过，有没有改动不清楚import React from 'react'import PropTypes from 'prop-types'import { withRouter } from 'react-router'// A simple component that shows the pathname of the current locationclass ShowTheLocation extends React.Component {&nbsp; static propTypes = {&nbsp; &nbsp; match: PropTypes.object.isRequired,&nbsp; &nbsp; location: PropTypes.object.isRequired,&nbsp; &nbsp; history: PropTypes.object.isRequired&nbsp; }&nbsp; render() {&nbsp; &nbsp; const { match, location, history } = this.props&nbsp; &nbsp; return (&nbsp; &nbsp; &nbsp; <div>You are now at {location.pathname}</div>&nbsp; &nbsp; )&nbsp; }}// Create a new component that is "connected" (to borrow redux// terminology) to the router.export default withRouter(ShowTheLocation)包一层withRouter之后，就可以访问到你想要的属性了，你还可以进一步学习，看看里面都有些什么。
