使用props在父级和子级组件之间进行js通信，将道具从商店发送到产品详细信息组件

Question

这是一个shop组件，它是父组件，在其中有单击处理程序上的图像，需要在其中将数据发送到称为Prod Details的子组件。

而click事件是detailMovie，因此需要使用道具将其传递给孩子

子组件应显示从功能中选择的数据

import React from "react";
import { Link, browserHistory } from "react-router";
import { ProdDetails } from "./ProductDetails";
// import ProductsJSON from "../data/products.json";

export class Shop extends React.Component {
  // to route to details page from list
  onNavigateProdDetails() {
    browserHistory.push("/proddetails");
  }
  constructor(props) {
    super(props);
    this.state = {
      data: [],
      selectedData: {}
    };
  }

  //API Call to fetch data
  componentDidMount() {
    fetch("https://facebook.github.io/react-native/movies.json")
      .then(Response => Response.json())
      .then(findresponse => {
        console.log(findresponse.movies);
        this.setState({
          data: findresponse.movies
        });
      });
  }
  detailMovie(moviedata) {
    //this.props.clickedItem = moviedata;
    this.selectedMovieList = moviedata;
  };

  render() {
    // find the clicked item and local storage
    let selectedMovie;
    

    return (
      <div className="shop pad-30">
        <h1>Latest Arrivals</h1>
        <div className="shop-inner">
          <div className="prods-wrap">

                  onClick={() => this.detailMovie(moviedata)}
                  data-key={moviedata.id}
