Reactjs在点击和不重新渲染时未显示确切的组件

编程问答 2022-08-22

问题描述

如果我单击FeatureCard组件，我一直在尝试在React-Bootstrap模式中显示ProductCard组件。这两个组件都是可重用的组件。我在2行中有8个FeatureCard组件，每个FeaturCard + ProductCard组件具有相似的图像，标题和价格道具。因此，如果我单击相关的FeatureCard组件，我想显示相关的ProductCard组件。

现在，下面的给定代码由我编写，我是js和Reactjs的初学者。请查看代码，并帮助我解决以下这三件事：

  1. 如果我单击FeatureCrad组件，则不会在模态内显示相关的ProductCard组件
  2. 如果我单击模式的关闭按钮，则每个FeatureCard组件都会消失（不会重新呈现为先前的状态
  3. 我编写的代码很糟糕，可以为我编写更好的代码

注意：我想要一个简单的结果：如果单击功能卡[0]，则要显示productCard [0]，依此类推。我已经在这个问题上停留了4天了。请帮我摆脱这个问题。 预先感谢。

这是我的Shirt.js文件，上面的所有问题均在此文件中出现：
