draft.js 如何将道具传递给装饰器的策略函数

Question

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);

Answer 1

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
  }
]);
