如何獲得 <Field> redux-form 7.0.0中的值

Question

 class Form extends React.Component { constructor(props) { super(props); this.handleClick = this.handleClick.bind(this); } handleClick() { const { Add, noteList } = this.props; Add('this is title's value' , 'this is content's value'); } render() { const { handleSubmit, noteList: { list } } = this.props; return ( <form onSubmit={handleSubmit(this.handleClick)}> <div> <Field className="title" name="title" component="input" type="text" /> </div> <div> <Field className="content" name="content" component="textarea" /> </div> <div> <button type="submit" onClick={(e) => { list ? this.handleClick : e.preventDefault(); }}>add</button> </div> </form> ); } } 

當我點擊按鈕時，我希望將這兩個值添加到一個函數中添加為兩個參數來執行異步操作，我應該怎么做，請幫助我

handleClick函數中的字段值可以在onSubmit作為對象獲得。

class Form extends React.Component {
  constructor(props) {
    super(props);
    this.handleClick = this.handleClick.bind(this);
  }

  handleClick(values) {
    const { Add, noteList } = this.props;
    Add(values.title , values.content);
  }

  render() {
    const { handleSubmit, noteList: { list } } = this.props;
    return (
      <form onSubmit={handleSubmit(this.handleClick)}>
        <div>
          <Field className="title" name="title" component="input" type="text" />
        </div>
        <div>
          <Field className="content" name="content" component="textarea" />
        </div>
        <div>
          <button type="submit" onClick={(e) => { list ? this.handleClick : e.preventDefault(); }}>add</button>
        </div>
      </form>
    );
  }
}
