如何在特定按键上提交redux-form?

我有一个redux-form集成的React组件(redux格式v7.0.1),当用户同时按下commandenter时,我试图触发提交。

我可以成功检查是否按下了两个键,但是我无法使用handleSubmit通过表单外的函数提交表单。

如何将handleSubmit用于我的onSubmit功能?

方法:

 constructor(props){
  super(props);

  this.state = {
     commandKeyPressed: false
  }

  this.onSubmit = this.onSubmit.bind(this);
  this.handleKeyDown = this.handleKeyDown.bind(this);
 }

 onSubmit(values){
  console.log(values) // does not log anything
 }

 handleKeyDown(e){
    if (e.keyCode === 91){
      this.setState({commandKeyPressed: true});
    }
    // enter key is pressed afterwards while the keyCode is stored in a map to check if it was entered

    if (e.key === 'Enter') {
      e.preventDefault();

      if (this.state.commandKeyPressed) {
      //logs 'trying to submit', but does not call this.onSubmit
      console.log('trying to submit',this.props.handleSubmit(this.onSubmit)); 
      }
    }
  } 

形式:

return (
      <div>
        <div className="ama-submit-field reply-container">
            <form ref='commentReplyRef' onSubmit={handleSubmit(this.onSubmit)}>
              <Field
                name="commentReply"
                keyDown={e => this.handleKeyDown(e)}
                keyUp={e => this.handleKeyUp(e)}
                type="input"
                component={myCustomField}
                label={text}>
                </Field>
            </form>
        </div>
     </div>
 )

好的,我发现了一个针对其他感兴趣的人的解决方法。我认为这是一个黑客,但它适用于我。

当我创建表单时

let CommentForm = reduxForm({
  validate,
  form: 'Comment',
  onSubmit: function(values){return values}
})(Comment);

export default CommentForm

我使用onSubmit函数返回我的值。 我还更改了我的验证函数,以返回一个带有输入字段错误键的对象:

function validate(values){
  const errors = {};
  if (!values.commentReply){
    errors.commentReply = {error:true, text:'Please enter a question.'}
  }

  return errors;
}

然后,在handleKeyDown

handleKeyDown(e){
    if (e.keyCode === 91){
      this.setState({commandKeyPressed: true});
    }
    // enter key is pressed afterwards while the keyCode is stored in a map to check if it was entered

    if (e.key === 'Enter') {
      e.preventDefault();

      if (this.state.commandKeyPressed) {
       var values = this.props.handleSubmit();
       if (!values.commentReply.hasOwnProperty('error'){
        this.onSubmit(values);
       }
    }
  } 

这允许我使用适当的值在我的react组件内触发我的提交函数。我认为更好的做法是将所有提交逻辑移动到reduxForm属性,但是我在React onSubmit函数中有很多特定于状态的行为,我只是选择将其保留在那里。
