How to change list status in react

Requirements

Loop a list through sharing For a certain operation, when a certain sub-item is clicked, only this sub-item will change, and other items will remain unchanged.

Idea

Loop a list, change the original array item through index, and change the original array through state, so that The list re-renders.

Using UI components

I use React for development, and the plug-in uses antd. No matter what plug-in is used here, Just understand the above ideas.

Demonstration effect

Code implementation

import React from 'react';
import { Layout,List, Button } from 'antd';

export default class App extends React.Component{ 
  state={    
     list:[
      {
        "seqNo": 1001,
        "appname_en": "Baidu's website",
      },
      {
        "seqNo": 1002,
        "appname_en": "Google's official website",
      },
      {
        "seqNo": 1003,
        "appname_en": "Amazon.com",
      },
      {
        "seqNo": 1004,
        "appname_en": "Sina website",
      },
      {
        "seqNo": 1005,
        "appname_en": "Tencent's official website",
      },
      {
        "seqNo": 1006,
        "appname_en": "Netease's official website",
      },
      {
        "seqNo": 1007,
        "appname_en": "China yahoo website",
      }
    ]
  }
  handleItem=(index,isReject)=>{
    let list = this.state.list;
    list[index].isReject = isReject;
    this.setState({
      list
    })
  }
  render(){
    return (<div style={{padding:&#39;0 20px&#39;}}>
          <List
          className="demo-loadmore-list"
          itemLayout="horizontal"
          dataSource={this.state.list}
          renderItem={(item,index) => (
            <List.Item
              actions={[item.isReject===0?&#39;已驳回&#39;:item.isReject===1?&#39;已通过&#39;:<>
                <Button type="dashed" onClick={()=>this.handleItem(index,0)}>驳回</Button>, 
                <Button type="dashed" onClick={()=>this.handleItem(index,1)}>通过</Button></>
              ]}
            >
              <List.Item.Meta
                title={<a href="https://ant.design">{item.appname_en}</a>}
                description="Ant Design, a design language for background applications, is refined by Ant UED Team"
              />
              <div>content</div>
            </List.Item>
          )}
        />

    </div>
    );
  }
}

Code usage

If You are using the antd plug-in. Just copy the above example code and put it in one of your components. If not, just understand that the core idea is to change the original array so that the array can be re-rendered. If you have a better idea, please tell me~

The code is placed on github
