React.jsでformのSubmitを無効化させるとき

よく忘れるのでメモ
e.preventDefault();
してからAction

class GeneratePin extends Component {
  handleSubmit(e) {
    e.preventDefault();
    const { someAction } = this.props;
    someAction();
  }

  render() {
    return (
      <form
        className="form-horizontal"
        onSubmit={this.handleSubmit.bind(this)}>
        <Input type="select" label="" name="num" placeholder="">
          <option value="1">1</option>
          <option value="2">2</option>
          <option value="3">3</option>
        </Input>
        <button className="btn btn-default">送信</button>
      </form>
    );
  }
}
