如何在状态改变时改变DraftJS编辑器的初始内容？

import React, { Component } from 'react';
import { Editor, EditorState } from 'draft-js';

class MyEditor extends Component {
  constructor(props) {
    super(props);
    this.state = {
      editorState: EditorState.createEmpty(), // 初始化编辑器的初始内容为空
      initialContent: '这是初始内容', // 初始内容
    };
  }

  componentDidMount() {
    // 在组件挂载后，将初始内容设置为编辑器的初始内容
    this.setState({
      editorState: EditorState.createWithContent(
        ContentState.createFromText(this.state.initialContent)
      ),
    });
  }

  handleChange = (editorState) => {
    // 监听编辑器状态的改变
    this.setState({ editorState });
  };

  render() {
    return (
      <Editor
        editorState={this.state.editorState}
        onChange={this.handleChange}
      />
    );
  }
}

export default MyEditor;
