draft.js 如何将道具传递给装饰器的策略函数

How to pass props to strategy function for decorator in draft.js

我有一个装饰器的策略函数,我想将道具传递给策略函数 我试过下面的代码,但它让我无法读取 属性 undefine

的道具
const  highlightWorngWords = (contentBlock, callback , props  )  => {
let text = contentBlock.getText();
let worngWords =  props.errorWordslist ? props.wongwords : []  ;
console.log('wong words', worngWords);  
let start ; 
worngWords.forEach(word => {
  start = text.indexOf(word);
  if (start !== -1) {
    callback(start, start + word.length);
   }
 })
}

props 只是我从 mapStateToProps 获取的单词数组,我确实尝试在函数内部分配值并且它有效 但是当我想将道具传递给函数时它不会工作 知道如何将道具传递给它

import React, { Component  , Fragment} from 'react';
import { connect } from 'react-redux';
import * as actionCreators from '../../store/actions/index';
import Footer from '../Footer/Footer';
import { Editor, EditorState , CompositeDecorator   } from 'draft-js';
import HighlightedWords   from './MyComponent'
var  h2p  = require('html2plaintext');




class Main extends Component {
    constructor(props) {
        super(props);
        this.state = { 
          editorState: EditorState.createEmpty(compositeDecorator),
          subjectTitle: "",
      } 
      this.handleChange = this.handleChange.bind(this);
      this.animEditor = this.animEditor.bind(this);

    }

    handleChange =  (editorState) =>  {
      let TextValue = editorState.getCurrentContent().getPlainText();
      this.setState({
        editorState,
      });
      var text =  h2p(editorState.getCurrentContent().getPlainText());
      console.log("satet" , text);
      this.props.onChangeText(text);
      this.props.onSpellCheck(text); 
    }


    return(
    <Fragment>
        <main id="main-container" className="main_container">
        <section data-simplebar="init" id="editor-wrap" className="editor_wrap" ss-container='true'>

          <div 
           id="dhad-editor" 
           className="dhad_editor"  
          >
          <Editor
                  editorState={this.state.editorState}
                  onChange={this.handleChange} 
          />
          </div>
        </section>      
      </main>

    </Fragment>
    );
 }
}   
const  highlightWorngWords = (contentBlock, callback)  => {
  let text = contentBlock.getText();
 let worngWords =  this.props.errorWordslist ? this.props.errorWordslist:[];
  console.log('wong words', worngWords);  
  let start ; 
  worngWords.forEach(word => {
    start = text.indexOf(word);
    if (start !== -1) {
      callback(start, start + word.length);
     }
   })
}
const compositeDecorator = new CompositeDecorator([
  {
    strategy: highlightWorngWords.bind(this), //here
    component: HighlightedWords ,
   }
 ]);
const mapStateToProps = state => {
  return {
      text: state.edi.text ,
      errorWordslist: state.edi.errorWordslist,
      correctionsList: state.edi.correctionsList 
  };
};

const mapDispatchToProps = dispatch => {
return {
    onStart: () => dispatch(actionCreators.start()),
    onChangeText: (value)   => dispatch(actionCreators.TextChange(value)),
    onSpellCheck: (word)    => dispatch(actionCreators.ErorrWordsList(word)),

}
};



export default connect( mapStateToProps , mapDispatchToProps ) (Main);

the props is just an array of words I am getting it from mapStateToProps

在组件中添加函数 class 并保留箭头函数声明以自动绑定组件上下文。

highlightWorngWords = (contentBlock, callback)  => {
let text = contentBlock.getText();
let worngWords =  this.props.errorWordslist ? this.props.wongwords : []; //HERE
console.log('wong words', worngWords);  
let start ; 
worngWords.forEach(word => {
  start = text.indexOf(word);
  if (start !== -1) {
    callback(start, start + word.length);
   }
 })
}

然后修改构造函数中的装饰器声明指向this.highlightWorngWords

const compositeDecorator = new CompositeDecorator([
  {
    strategy: this.highlightWorngWords, //here
    component: HighlightedWords
  }
]);
