react-draft-wysiwyg富⽂本的使⽤1.分析需求
实现富⽂本编辑功能，通过与后台传输html字符串，实现保存、编辑、回显功能。
2.下载依赖
npm install
3.引⼊
import { Editor } from 'react-draft-wysiwyg';
import 'react-draft-wysiwyg/dist/react-draft-wysiwyg.css';
import { EditorState, convertToRaw, ContentState } from 'draft-js';
import draftToHtml from 'draftjs-to-html';
import htmlToDraft from 'html-to-draftjs';
4.存储状态
this.state = {
editorState: ateEmpty(),
};
5.jsx部分
<Editor
editorState={editorState}
toolbarClassName="toolbarClassName"
wrapperClassName="wrapperClassName"
editorClassName={styles.editor}
onEditorStateChange={EditorStateChange} //
//className={styles.demo-editor}
style={{
minHeight: '500px',
}}
/>
6.向后台传输数据
6.1.保存数据
onEditorStateChange = editorState => {editor bar
this.setState({
editorState,
});
};
6.2.转换格式调取接⼝
dispatch({
type: 'Carstylescenter/addBrandIntroduce',
payload: {
brandId,
desc: draftToHtml(CurrentContent())),
},
});
7.富⽂本回显
const descInit = response.data.brandDesc
if (descInit && descInit !== 'null') {
const contentBlock = htmlToDraft(descInit);
const contentState = tBlocks);
const editorState = ateWithContent(contentState);
this.setState({ editorState });
}
