在react中添加动态输入数据时，e.target.value未定义

handleChange = (e) => {
  console.log(e.target.value);
}

render() {
  return (
    <input type="text" onChange={this.handleChange} />
  );
}

handleChange = (param, e) => {
  console.log(e.target.value);
  console.log(param);
}

render() {
  return (
    <input type="text" onChange={(e) => this.handleChange("param", e)} />
  );
}

class MyComponent extends React.Component {
  handleChange = (e) => {
    console.log(e.target.value);
  }

  render() {
    return (
      <input type="text" onChange={this.handleChange} />
    );
  }
}
