How retrieve text from draftjs

Question

I'm trying to edit a text and then retrieve it and update the database on the server side

this is the code I'm using

constructor(props,context){
    super(props,context);
    this.handleOnClick = this.handleOnClick.bind(this);

    const processedHTML = DraftPasteProcessor.processHTML(this.props.rule.description.replace(/\n/g, "<br />"));
    const contentState = ContentState.createFromBlockArray(processedHTML); 
    var editorState = EditorState.createWithContent(contentState);
    var editorState = EditorState.moveFocusToEnd(editorState);
    this.state = {editorState: editorState};
    this.onChange = (editorState) => this.setState({editorState});
}



handleOnClick(event) {
   var text = this.state.editorState.getCurrentContent().getBlocksAsArray();
   var finalText;
   text.map((item) => {
   finalText = item.getText() + finalText});
   console.log(finalText)

  render(){

    return(
    <div>
    <Col smOffset={2} mdOffset={1}>
    <PageHeader>
        {this.props.rule.title}
    </PageHeader>
    <Editor
      editorState={this.state.editorState}
      onChange={this.onChange}
    />
    </Col>

     <Col smOffset={2} mdOffset={1}>
    <Button onClick = {this.handleOnClick()}>Update rule</Button>
    </Col>
    </div>
    );

}

But I'm having a problem, draftJs returns the text without the \n so I'd save the text badly formatted, is there any way to get the text with breaklines?

Answer 1

The best way to retrieve text is by just using editorState.getCurrentContent().getPlainText('\u0001')

Note that the function getPlainText will always create a single space between blocks, so you need to send \u0001 as a parameter

Answer 2

You can make use of convertToRaw function of DraftJS something like following to get the text with break lines:

import {
  convertToRaw,
} from 'draft-js';
const blocks = convertToRaw(editorState.getCurrentContent()).blocks;
const value = blocks.map(block => (!block.text.trim() && '\n') || block.text).join('\n');
