在react中使用RadioGroup时如何获取完整的事件对象

import React from 'react';
import ReactDOM from 'react-dom';

class MyForm extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      selectedValue: '',
    };
  }

  handleChange = (event) => {
    console.log(event); // 在这里可以获取完整的事件对象
    this.setState({ selectedValue: event.target.value });
  }

  render() {
    return (
      <form>
        <RadioGroup name="myRadioGroup" value={this.state.selectedValue} onChange={this.handleChange}>
          <label>
            <input type="radio" value="option1" />
            Option 1
          </label>
          <label>
            <input type="radio" value="option2" />
            Option 2
          </label>
          <label>
            <input type="radio" value="option3" />
            Option 3
          </label>
        </RadioGroup>
      </form>
    );
  }
}

ReactDOM.render(<MyForm />, document.getElementById('root'));
