React 列表页面传递参数

React 列表进入详情页面

首先安装 react-router-dom (4.0) npm/yarn install react-router-dom

路由跳转配置

列表 父组件 this.props.history.push( { pathname:'/detail', state: data } )

上述的data 为明细的数据

那么详情页面如何接收父组件的数据呢？

const detaildata = this.prop.location.stata.data

注意如果 父组件进入详情页面 this.props.history.push();这个报错时. 引入 import { withRouter } from 'react-router'即可。

部分代码如下

列表组件

import React, { Component } from 'react'
import { withRouter } from 'react-router'; 
 

export class  List extends Component {
    constructor(props) {
        super(props);
        this.state={
            list: [
                {

        }
     }

    viewdetail (item)  {
        this.props.history.push({ pathname: '/detail', state: {data:item} })

    render() {
        return (

                {ths.state.list.map(item => {
                    return (

export default withRouter(List)

详情页面

import React, { Component } from 'react'
 

export class DetailList extends Component {
    constructor(props) {
        super(props)
         const data = this.props.location.state.data;
        this.state={
            data:data
        }
    }

    render() {
        return (
            <div>
