        </div>
      }
        </div>

  </div>
    );
 }
}

It's enough to clear the copySuccess state after 5000 ms:

copyToClipboard = (e) => {
this.textArea.select();
document.execCommand('copy');
e.target.focus();
this.setState({ copySuccess: 'Copied!' }, () => setTimeout( () => this.setState({ copySuccess: '' }) ,5000));
};

CodePudding user response：

Modify your copyToClipboard function like this:

copyToClipboard = (e) => {
this.textArea.select();
document.execCommand('copy');
e.target.focus();
this.setState({ copySuccess: 'Copied!' });
setTimeout(() => {
    this.setState({ copySuccess: '' });
  }, 5000);
};
