React "this“未在方法子异步函数中定义

class MyComponent extends React.Component {
  handleClick = () => {
    console.log(this.props);
  }

  render() {
    return (
      <button onClick={this.handleClick}>Click me</button>
    );
  }
}

class MyComponent extends React.Component {
  handleClick() {
    console.log(this.props);
  }

  render() {
    return (
      <button onClick={this.handleClick.bind(this)}>Click me</button>
    );
  }
}

class MyComponent extends React.Component {
  handleClick = async () => {
    console.log(this.props);
    await someAsyncTask();
    console.log(this.props); // 此处的"this"仍然指向组件实例对象
  }

  render() {
    return (
      <button onClick={this.handleClick}>Click me</button>
    );
  }
}
