对e.target.value以外的其他内容进行React onClick状态更改，而不使用redux

constructor(props) {
  super(props);
  this.state = {
    value: '',
    otherContent: '',
  };
}

handleClick = () => {
  this.setState(prevState => ({
    otherContent: prevState.otherContent === 'someValue' ? 'newValue' : 'someValue',
  }));
}

render() {
  return (
    <div>
      <input
        type="text"
        value={this.state.value}
        onChange={e => this.setState({ value: e.target.value })}
      />
      <button onClick={this.handleClick}>Change Other Content</button>
      <p>{this.state.otherContent}</p>
    </div>
  );
}
