我有一个用例，我必须将 HTML 模板呈现到编辑器上。我也在探索 Draftjs。我已经完成了基本设置，并为简单的文本渲染了 Draftjs 编辑器。

但是如果我将一个 HTML 字符串传递给同一个编辑器组件，我会得到以下异常。

DraftEditorContents-core.react.js:80 Uncaught TypeError: nextEditorState.getDirectionMap is not a function
    at DraftEditorContents.shouldComponentUpdate (DraftEditorContents-core.react.js:80)
    at checkShouldComponentUpdate (react-dom.development.js:11345)
    at updateClassInstance (react-dom.development.js:11754)
    at updateClassComponent (react-dom.development.js:13153)
    at beginWork (react-dom.development.js:13824)
    at performUnitOfWork (react-dom.development.js:15863)
    at workLoop (react-dom.development.js:15902)
    at HTMLUnknownElement.callCallback (react-dom.development.js:100)
    at Object.invokeGuardedCallbackDev (react-dom.development.js:138)
    at invokeGuardedCallback (react-dom.development.js:187)

知道我需要做什么才能让这个工作在草稿上吗？如果 draftjs 不适合这个，那么你建议任何其他库作为替代方案？

要将 HTML 字符串传递给编辑器，您可以使用 Draftjs 编辑器提供的 convertFromHTML 函数：

componentWillMount() {
    const compositeDecorator = new CompositeDecorator([
      {
        strategy: this.handleStrategy,
        component: HandleSpan,
        readOnly: true,
      },
    ]);
    const { value } = this.props;
    if (value) {
      const blocksFromHTML = convertFromHTML(value.replace(/(?:\r\n|\r|\n)/g, '<br /><br />'));
      const state = ContentState.createFromBlockArray(
        blocksFromHTML.contentBlocks,
        blocksFromHTML.entityMap,
      );
      this.state = {
        editorState: EditorState.createWithContent(
          state,
          compositeDecorator,
        ),
      };
    } else {
      this.state = {
        editorState: EditorState.createEmpty(),
      };
    }
  }

然后你可以在渲染函数中使用 this.state.editorState 作为道具：

<Editor
    editorState={this.state.editorState}
/>
