draftjs how to initiate an editor with content

Question

Stumbled on this cool text editor, draft.js by Facebook. I tried to follow the example in Github, but I want to create an editor with content instead of an empty editor.

var EditorState = Draft.EditorState;

var RichEditor = React.createClass({
   getInitialState(){
      return {editorState: EditorState.createWithContent("Hello")}
      //the example use this code to createEmpty editor
     // return ({editorState: EditorState.createEmpty()})
   }
});

When I run it, it throws an error with the following message "Uncaught TypeError: contentState.getBlockMap is not a function".

Answer 1

The first argument to EditorState.createWithContent is a ContentState, not a string. You need to import ContentState

var EditorState = Draft.EditorState;
var ContentState = Draft.ContentState;

Use ContentState.createFromText And pass the result to EditorState.createWithContent.

return {
  editorState: EditorState.createWithContent(ContentState.createFromText('Hello'))
};
