Get the selected content as plain text

You can use text API to get the selected content as plain text from React Document Editor component.

The following example code illustrates how to add search in google option in context menu for the selected text.

import * as ReactDOM from 'react-dom';
import * as React from 'react';
import {
  DocumentEditorContainerComponent,
  Toolbar,
} from '@syncfusion/ej2-react-documenteditor';
import { MenuItemModel } from '@syncfusion/ej2-navigations';

DocumentEditorContainerComponent.Inject(Toolbar);
function App() {
  let container: DocumentEditorContainerComponent;
  let contentChanged: boolean = false;
  function onCreate() {
    // creating Custom Options
    let menuItems: MenuItemModel[] = [
      {
        text: 'Search In Google',
        id: 'search_in_google',
        iconCss: 'e-icons e-de-ctnr-find',
      },
    ];
    // adding Custom Options
    container.documentEditor.contextMenu.addCustomMenu(menuItems, false);
    // custom Options Select Event
    container.documentEditor.customContextMenuSelect = (
      args: any
    ): void => {
      // custom Options Functionality
      let id: string = container.documentEditor.element.id;
      switch (args.id) {
        case id + 'search_in_google':
          // To get the selected content as plain text
          let searchContent: string =
            container.documentEditor.selection.text;
          if (
            !container.documentEditor.selection.isEmpty &&
            /\S/.test(searchContent)
          ) {
            window.open('http://google.com/search?q=' + searchContent);
          }
          break;
      }
    };
  }
  return (
    <DocumentEditorContainerComponent
      id="container"
      ref={(scope) => {
        container = scope;
      }}
      height={'590px'}
      serviceUrl="https://ej2services.syncfusion.com/production/web-services/api/documenteditor/"
      enableToolbar={true}
      created={onCreate}
    />
  );
}
export default App;
ReactDOM.render(<App />, document.getElementById('sample'));

You can add the following custom options using this API,

• Show synonyms for the selected word in context menu and replace with selected synonym using the setter method of same API.

Get the selected content as SFDT (rich text)

You can use sfdt API to get the selected content as plain text from React Document Editor component.

The following example code illustrates how to get the content of a bookmark and export it as SFDT.

import * as ReactDOM from 'react-dom';
import * as React from 'react';
import {
  DocumentEditorContainerComponent,
  Toolbar,
} from '@syncfusion/ej2-react-documenteditor';
DocumentEditorContainerComponent.Inject(Toolbar);
function App() {
  let container: DocumentEditorContainerComponent;
  let contentChanged: boolean = false;
  function onCreate() {
    // To insert text in cursor position
    container.documentEditor.editor.insertText('Document editor');
    // To select all the content in document
    container.documentEditor.selection.selectAll();
    // Insert bookmark to selected content
    container.documentEditor.editor.insertBookmark('Bookmark1');
    //Select the bookmark
    container.documentEditor.selection.selectBookmark('Bookmark1');
    // To get the selected content as sfdt
    let selectedContent: string = container.documentEditor.selection.sfdt;
    // Insert the sfdt content in cursor position using paste API
    container.documentEditor.editor.paste(selectedContent);
  }
  return (
    <DocumentEditorContainerComponent
      id="container"
      ref={(scope) => {
        container = scope;
      }}
      height={'590px'}
      serviceUrl="https://ej2services.syncfusion.com/production/web-services/api/documenteditor/"
      enableToolbar={true}
      created={onCreate}
    />
  );
}

ReactDOM.render(<App />, document.getElementById('sample'));
