为什么单击“颜色框”后未显示复制的消息？

如何解决为什么单击“颜色框”后未显示复制的消息？

我正在开发一种Color应用程序来选择您需要的颜色，并且遇到一个问题，即用户单击颜色框时复制的消息不会显示 你能告诉我为什么复制的消息没有显示

传递的道具是颜色名称和颜色背景 例如-<ColorBox name = "BEEKEEPER 500" background = "#eedd86"/>

的代码 ColorBox.js

import React,{ Component } from 'react'
import {copyToClipboard} from 'react-copy-to-clipboard'
import './ColorBox.css';
export default class ColorBox extends Component {
    constructor(props) {
        super(props)    
        this.state = {
            copied:false             
        }
        this.changecopyState = this.changecopyState.bind(this);
    }
    changecopyState(){
            this.setState({copied:true},()=>{
            setTimeout(()=>this.setState({copied:false}),1500)
        });
    }

    render() {
        const {name,background} = this.props;
        const {copied} = this.state;
        return (
            <copyToClipboard text={background} oncopy={this.changecopyState}>
            <div style={{ background }} className='ColorBox'>
                <div 
                style={{ background }} 
                className={`copy-overlay ${copied && "show"}`}
                />
                <div className={`copy-msg ${copied && "show"}`}>
                    <h1>copied</h1>
                    <p>{background}</p>
                    </div>
              <div className="copy-container">
              <div className="Box-content">
               <span>{name}</span>
             </div>
             <button className='copy-button'>copy</button>
             </div>
             <span className='see-more'>More</span>
            </div>
            </copyToClipboard>
        )
    }
}
