Redux 表单 - 在没有按钮但在字段更改时提交

Question

我正在创建一个带有 material ui 输入的 redux-form shell——我正在尝试创建一个 genericForm 处理程序，它将允许可以将字段和按钮对象泵入组件——我现在需要创建一个没有提交按钮的表单由于设计 - 但如果没有按钮，则能够在字段更改时提交表单。我有一个 handleChange 函数，它将监听所有字段类型的 onChange 事件——并带回字段名和新值——它现在可以知道表单是否有按钮——但我不确定在哪里以及如何开发它如果字段发生更改，进一步将数据提交给父级https://redux-form.com/6.0.0-alpha.7/examples/asyncvalidation/FormShell.jsimport React from 'react';import { reduxForm } from 'redux-form';import FieldMaker from './FieldMaker';import ButtonMaker from './ButtonMaker';const FormShell = props => {  const { handleSubmit, pristine, reset, previousPage, submitting } = props  return (    <form onSubmit={handleSubmit}>      <FieldMaker fields={props.fields} hasButtons={props.buttons.length > 0? true: false} />      <ButtonMaker buttons={props.buttons} pristine={pristine} submitting={submitting} reset={reset} previousPage={previousPage} />    </form>  )}export default reduxForm()(FormShell)通用表单.js      <FormShell         initialValues={this.props.initialValues}         enableReinitialize={true}//allow form to be reinitialized        fields={this.props.fields}         buttons={this.props.buttons}        form={this.state.uuid}// a unique identifier for this form        validate={this.validateHandler}// <--- validation function given to redux-form        warn={this.warnHandler}//<--- warning function given to redux-form        onSubmit={this.submit}        previousPage={this.props.previousPage}        destroyOnUnmount={this.props.destroyOnUnmount}// <------ preserve form data        forceUnregisterOnUnmount={this.props.forceUnregisterOnUnmount}// <------ unregister fields on unmount       />

我把它变成了一个组件并添加了一个函数，该函数从 FieldMaker 组件中获取字段更改

import React, { Component } from 'react';

import { reduxForm } from 'redux-form';

import FieldMaker from './FieldMaker';

import ButtonMaker from './ButtonMaker';

class FormShell extends Component {

 

 constructor(props, context) {

    super(props, context);

    this.fieldChanged = this.fieldChanged.bind(this);

 }

  fieldChanged(field, value){

      console.log("Fields have changed", field, value);

      //if it doesn't have any submit buttons -- then submit the form on change of fields

      if(!this.props.buttons.length > 0){

        console.log("submit the form as a buttonless form");

        setTimeout(() => {

          this.props.handleSubmit();

        }, 1);        

      }

  }

 render(){

  const { handleSubmit, pristine, reset, previousPage, submitting } = this.props

  console.log("THIS FORM SHELL PROPS", this.props);

  return (

    <form onSubmit={handleSubmit}>

      <FieldMaker fields={this.props.fields} fieldChanged={this.fieldChanged} />

      <ButtonMaker buttons={this.props.buttons} pristine={pristine} submitting={submitting} reset={reset} previousPage={previousPage} />

    </form>

  )

 }

}

export default reduxForm()(FormShell)
