添加图像draft-js-image-plugin

如何解决添加图像draft-js-image-plugin

我尝试了多种方法来尝试将图像附加在草稿js中。

我的尝试遵循了教程https://www.draft-js-plugins.com/plugin/image中的示例。对于“添加图像按钮示例”，可在此处https://github.com/draft-js-plugins/draft-js-plugins/tree/master/docs/client/components/pages/Image/AddImageEditor中找到其完整源代码。我也尝试过这篇不使用图像插件做类似事情的中等文章https://medium.com/@siobhanpmahoney/building-a-rich-text-editor-with-react-and-draft-js-part-2-4-persisting-data-to-server-cd68e81c820。

如果我将初始状态设置为已嵌入的图像，则会进行渲染。但是，当使用稍后添加它的机制时，它似乎不起作用。我读过一些提到各种版本的plugin / draft.js的问题。
我的版本：

“ draft-js-image-plugin”：“ ^ 2.0.7”， “ draft-js”：“ ^ 0.11.6”，

import { EditorState } from 'draft-js';
import Editor from 'draft-js-plugins-editor';
import createInlinetoolbarPlugin,{ Separator } from 'draft-js-inline-toolbar-plugin';
import createImagePlugin from 'draft-js-image-plugin';
import 'draft-js/dist/Draft.css';
import 'draft-js-inline-toolbar-plugin/lib/plugin.css';
import {
  ItalicButton,BoldButton,UnderlineButton,HeadlineOneButton,CodeButton,UnorderedListButton,OrderedListButton,BlockquoteButton,} from 'draft-js-buttons';

interface TextEditorProps {
  label?: string;
  value: EditorState;
  onChange?: (editorState: EditorState) => void;
  className?: string;
  disabled?: boolean;
}

const useStyles = makeStyles((theme) => ({
  label: {
    margin: theme.spacing(1)
  },editor: {
    BoxSizing: 'border-Box',border: '1px solid #ddd',cursor: 'text',padding: '16px',borderRadius: '2px',marginBottom: '2em',BoxShadow: 'inset 0px 1px 8px -3px #ABABAB',background: '#fefefe',minHeight: '50vh'
  }
}));
const inlinetoolbarPlugin = createInlinetoolbarPlugin();
const imagePlugin = createImagePlugin();
const { Inlinetoolbar } = inlinetoolbarPlugin;
const plugins = [inlinetoolbarPlugin,imagePlugin];
const TextEditor:React.FunctionComponent<TextEditorProps> = ({label,value,onChange,className,disabled }: TextEditorProps) => {
  const editor = React.useRef(null);
  const focusEditor = () => {
    editor.current.focus();
  }
  React.useEffect(() => {
    focusEditor()
  },[]);
  const classes = useStyles();
  const insertimage = () => {
    onChange(imagePlugin.addImage(value,"https://ichef.bbci.co.uk/news/976/cpsprodpb/12A9B/production/_111434467_gettyimages-1143489763.jpg"));
  }
  return (
    <Box className={className} onClick={focusEditor}>
      {label && <InputLabel className={classes.label}>{label}</InputLabel>}
      <div className="menuButtons">
          <button className="inline styleButton">
            <i
              className="material-icons"
              style={{
                fontSize: "16px",textAlign: "center",padding: "0px",margin: "0px"
              }}
              onClick={insertimage}
            >
              image
            </i>
          </button>
        </div>
      <Box className={!disabled && classes.editor} >
        <Editor
          ref={editor}
          editorState={value}
          onChange={onChange}
          plugins={plugins}
          spellCheck={true}
          readOnly={disabled}
        />
        {<Inlinetoolbar>
          {(externalProps) => (
            <>
              <BoldButton {...externalProps} />
              <ItalicButton {...externalProps} />
              <UnderlineButton {...externalProps} />
              <CodeButton {...externalProps} />
              <Separator {...externalProps} />
              <UnorderedListButton {...externalProps} />
              <OrderedListButton {...externalProps} />
              <BlockquoteButton {...externalProps} />
              <HeadlineOneButton {...externalProps} />
            </>
          )}  
        </Inlinetoolbar>}
      </Box>
    </Box>
  )
}

解决方法

您的 editorState 更改将覆盖 insertImage 的更改。您正在触发 focusEditor 以及onClick insertImage

,

如果您不介意动手学习如何插入内容，则不需要其他插件。

           <i
              className="material-icons"
              style={{
                fontSize: "16px",textAlign: "center",padding: "0px",margin: "0px"
              }}
              onClick={() => insertImage('https://ichef.bbci.co.uk/news/976/cpsprodpb/12A9B/production/_111434467_gettyimages-1143489763.jpg')}
            >

自定义insertImage函数，在您的情况下，editorState应该替换为'value'

import { EditorState,AtomicBlockUtils } from “draft-js”; //<-- need add this import

const insertImage = ( url ) => {
    const contentState = editorState.getCurrentContent();
    const contentStateWithEntity = contentState.createEntity(
        'IMAGE','IMMUTABLE',{ src: url },)
const entityKey = contentStateWithEntity.getLastCreatedEntityKey();
const newEditorState = EditorState.set( editorState,{ currentContent: contentStateWithEntity });
onChange(AtomicBlockUtils.insertAtomicBlock(newEditorState,entityKey,'')) //Update the editor state
};
