我正在处理点击事件我有一个列表，我想在点击列表项时设置 onClick 事件。并显示特定列表的<div>

代码：

import React from "react";
    import { Container, Grid,Accordion } from "semantic-ui-react";
    
    
    class Powerups extends React.Component{
       constructor(props){
        super(props);
        this.state={
          activeIndex: 1
        }
        this.handleClick = this.handleClick.bind(this);
        this.handleChange = this.handleChange.bind(this);
       }
       componentWillMount() {}
       componentWillUnmount() {}
       componentDidMount() {}
       componentWillReceiveProps(nProps) {}

                </Grid.Column>
            </Grid>
    
              
                  </Container>
    
           
    
           </div>
            )
        }
    }
    
    const mapStateToProps = ({ auth }) => {
        return { auth }
    }
    
    export default connect(mapStateToProps, {})(Powerups);

我希望当我点击像 import 这样的特定类别时，它会显示 import div

所以，我不明白这个，我会新尝试这个 请任何人帮忙

谢谢！

您可以为列表项创建一个对象数组，然后将列表信息传递给子组件并显示内容。

这是一个关于如何实现目标的工作示例，

代码沙盒 => https://codesandbox.io/s/frosty-bird-vqzzp?file=/src/App.js:0-892

import React, { useState } from "react";

import "./styles.css";

const listItems = [
  { id: "0", title: "One", content: " I AM ONE" },
  { id: "1", title: "Two", content: " I AM TWO" },
  { id: "2", title: "Three", content: " I AM THREE" }
];

const ListView = ({listId}) => {
  const listView = listItems.map((item) => {
    if (item.id === listId) {
      return <span>{item.content}</span>;
    }
  });

  return <div>{listView}</div>;
};

const App = () => {
  const [showListView, setShowListView] = useState(false);
  const [listId, setListId] = useState(null);

  const listClickHandler = (id) => {
    setListId(id);
  };

  const list = listItems.map((item) => {
    return <li onClick={() => listClickHandler(item.id)}>{item.title}</li>;
  });

  return (
    <div className="App">
      <ul>{list}</ul>

      <ListView listId={listId} />
    </div>
  );
};

export default App;
