如何在点击处理程序中获取event.target元素对应的react组件实例？

class MyComponent extends React.Component {
  handleClick = (event) => {
    // 在这里获取event.target元素对应的React组件实例
  }

  render() {
    return <div onClick={this.handleClick}>点击我</div>;
  }
}

import ReactDOM from 'react-dom';

class MyComponent extends React.Component {
  handleClick = (event) => {
    const domNode = event.target;
    const componentInstance = ReactDOM.findDOMNode(domNode);
    // componentInstance即为event.target元素对应的React组件实例
  }

  render() {
    return <div onClick={this.handleClick}>点击我</div>;
  }
}

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.myRef = React.createRef();
  }

  handleClick = () => {
    const componentInstance = this.myRef.current;
    // componentInstance即为event.target元素对应的React组件实例
  }

  render() {
    return <div ref={this.myRef} onClick={this.handleClick}>点击我</div>;
  }
}
