reactjs – redux-form：在输入onChange后触发Form onSubmit

我在redux-form中有一组简单的单选按钮.我需要单选按钮组的onChange事件来触发表单的onSubmit事件.

我正在使用redux-form v5.3.1

建立

RadioFormContainer.js

class RadioFormContainer extends Component {
  render() {
    const {submit} = this.props;
    return (
      <RadioForm submit={submit} />
    )
  }
}

const mapDispatchToProps = (dispatch) => {
  return {
    submit: function(values,dispatch) {
      // API call after validation
    }
  }
};

RadioForm.js

class RadioForm extends Component {
  render() {
    const {
      submit,// custom post-validation handler
      // via redux form decorator:
      handleSubmit,submitting
    } = this.props;
    return (
      <form onSubmit={handleSubmit(submit)}>
        <input {...radioField}
               checked={radioField.value == "one"}
               type="radio"
               value="one"
               disabled={submitting} />
        <input {...radioField}
               checked={radioField.value == "two"}
               type="radio"
               value="two"
               disabled={submitting} />
      </form>
    );
  }
}

尝试实现,不工作

1.从RadioForm上的componentWillReceiveProps调用handleSubmit

kyleboyle的proposal here根本不起作用.当我从componentWillReceiveProps调用nextProps.handleSubmit时,我得到this familiar error,Uncaught错误：你必须传递handleSubmit()一个onSubmit函数或传递onSubmit作为prop

componentWillReceiveProps(nextProps) {
  if (nextProps.dirty && nextProps.valid) {
    let doubleDirty = false;
    Object.keys(nextProps.fields).forEach(key => {
      if (nextProps.fields[key].value !== this.props.fields[key].value) {
        doubleDirty = true;
      }
    });
    if (doubleDirty) {
      nextProps.handleSubmit();
    }
  }
}

2.从onChange处理程序调用RadioForm上的提交

erikras proposes this here.但它对我不起作用,因为它会跳过验证.

<input // ...
       onChange={(event) => {
          radioField.handleChange(event); // update redux state
          this.submit({ myField: event.target.value });
       }} />

我认为Bitaru(same thread)在他的回复中试图说同样的话,但我不确定.为我调用onSubmit会导致异常Uncaught TypeError：_this2.props.onSubmit不是函数

3.通过this.refs调用表单上的提交

这导致表单实际提交,完全跳过redux-form

每：How to trigger a form submit in child component with Redux?

<input // ...
       onChange={(event) => {
         radioField.onChange(event);
         this.refs.radioForm.submit();
       }} />

您是否尝试添加隐藏的提交按钮

<input ref="submit" type="submit" style="display: none;"/>

和单选按钮onChange将调用refs.submit.click()？
