Question

我正在构建reactjs应用程序。

我已经创建了RichEditor的一个变体 - 它使用了draft.js - 我不确定如何为这个编辑器设置内容，以及如果要将其作为表单的一部分，如何检索它。

这是我目前的代码库

所以，如果我将其视为一个领域。

const initialValues = {editor: "I am a <h2>bit</h2> of dummy <b>html</b> text"}

<RichEditor initialValues={initialValues} />

^所以这样的事情 - 但如果它像反应还原形式一样，我将如何获得内容？

像这样？

import React from 'react'
import { Field, reduxForm } from 'redux-form'
import renderField from '../_SharedFormComponents/renderField'
import validate from './validateComplaint'
import warn from './warnComplaint'

const ComplaintSyncValidationForm= props => {
  const { handleSubmit, pristine, reset, submitting } = props

  const initialValues = {editor: "I am a <h2>bit</h2> of dummy <b>html</b> text"}
  return (
    <form onSubmit={handleSubmit}>
      <Field name="email" type="email" component={renderField} label="Email" />
      <RichEditor initialValues={initialValues} />
      <div>
        <button type="submit" disabled={submitting}>
          Complain
        </button>
        <button type="button" disabled={pristine || submitting} onClick={reset}>
          Clear Values
        </button>
      </div>
    </form>
  )
}

export default reduxForm({
  form: 'syncValidationComplaint', // a unique identifier for this form
  validate, // <--- validation function given to redux-form
  warn // <--- warning function given to redux-form
})(ComplaintSyncValidationForm)

// RichEditor.js

Answer 1

我将richtexteditor作为react-redux组件的一部分。它更新了keyups上的一个隐藏字段..它必须改变值而不是设置状态 - 这是为了欺骗现场已被触及的反应 - 还原形式＆＃34; ---虽然它没有像我想的那样完全复杂 - 如果显示清晰值按钮 - 将重置隐藏字段但不能恢复编辑器中的旧文本。

// renderRichFieldTextarea react-redux field。

import React from 'react'
import RichEditor from '../_SharedGlobalComponents/RichEditor';

class ContentContainer extends React.Component {
      constructor(props) {
        super(props);

        this.state = {
          value: this.props.input.value
        };

        this.handler = this.handler.bind(this);
      }

      handler(d) {
        this.props.input.onChange(d);
      }

      render() {
        const input = this.props.input;
        const placeholder = this.props.placeholder;
        const type = this.props.type;
        const boxclass = this.props.boxclass;

        return (
            <div>
              <RichEditor 
              initialValues={input.value} 
              handler={this.handler} 
              />
            <input {...input} type="hidden" />
            </div>
        );
      }
    }

const renderRichFieldTextarea = ({input, label, placeholder, boxclass, type, meta: {touched, error, warning}}) => (
  <div className='field'>
    <div>
      <label>{label}</label>
    </div>
    <div>
          <ContentContainer initialValues={input.value} onChange={this.onChange} input={input} placeholder={placeholder} type={type} boxclass={boxclass}/>
    </div>
  </div>
)

export default renderRichFieldTextarea

所以我在像这样的表单组件中使用它。

// EditPrivacySectionsSyncValidationForm - 反应还原形式

import React from 'react'
import { Field, reduxForm } from 'redux-form'
import { Row, Col, Collapse } from 'antd';

import renderField from '../_SharedFormComponents/renderField'
import renderRichFieldTextarea from '../_SharedFormComponents/renderRichFieldTextarea'
import renderRadioCheckField from '../_SharedFormComponents/renderRadioCheckField'

import renderError from '../_SharedFormComponents/renderError'

import validate from './validateEditSections'
import warn from './warnEditSections'

const Panel = Collapse.Panel;

const EditPrivacySectionsSyncValidationForm = props => {
  const { handleSubmit, pristine, reset, submitting } = props

  return (
    <form onSubmit={handleSubmit} >

      <Row>
        <Col xs={24} sm={24} md={24}>
          <div>
            <Field name="privacy" type="textarea" component={renderRichFieldTextarea} label="Privacy" placeholder="Please write here..." boxclass="tall"/>
          </div>          
        </Col>
      </Row>

      <div>
        <button type="submit" disabled={submitting}>
          Submit
        </button>{/*
        <button type="button" disabled={pristine || submitting} onClick={reset}>
          Clear Values
        </button>*/}
      </div>

    </form>
  )
}

//initialValues = {interest: "art"}
export default reduxForm({
  form: 'syncValidationEditPrivacySections', // a unique identifier for this form
  validate, // <--- validation function given to redux-form
  warn // <--- warning function given to redux-form
})(EditPrivacySectionsSyncValidationForm)
