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);
export class App extends React.Component<{}, {}> {
  container: DocumentEditorContainerComponent;
  public contentChanged: boolean = false;
  onCreate(): void {
    // creating Custom Options
    let menuItems: MenuItemModel[] = [
      {
        text: 'Search In Google',
        id: 'search_in_google',
        iconCss: 'e-icons e-de-ctnr-find',
      },
    ];
    // adding Custom Options
    this.container.documentEditor.contextMenu.addCustomMenu(menuItems, false);
    // custom Options Select Event
    this.container.documentEditor.customContextMenuSelect = (
      args: any
    ): void => {
      // custom Options Functionality
      let id: string = this.container.documentEditor.element.id;
      switch (args.id) {
        case id + 'search_in_google':
          // To get the selected content as plain text
          let searchContent: string =
            this.container.documentEditor.selection.text;
          if (
            !this.container.documentEditor.selection.isEmpty &&
            /\S/.test(searchContent)
          ) {
            window.open('http://google.com/search?q=' + searchContent);
          }
          break;
      }
    };
  }

  render() {
    return (
      <DocumentEditorContainerComponent
        id="container"
        ref={(scope) => {
          this.container = scope;
        }}
        height={'590px'}
        serviceUrl="https://ej2services.syncfusion.com/production/web-services/api/documenteditor/"
        enableToolbar={true}
        created={this.onCreate.bind(this)}
      />
    );
  }
}
ReactDOM.render(<App />, document.getElementById('root'));

DocumentEditorContainerComponent.Inject(Toolbar);
export class App extends React.Component<{}, {}> {
  container: DocumentEditorContainerComponent;
  public contentChanged: boolean = false;
  onCreate(): void {
   // To insert text in cursor position
   this.container.documentEditor.editor.insertText('Document editor');
   // To select all the content in document

   this.container.documentEditor.editor.paste(selectedContent);
  }

  render() {
return (
  <DocumentEditorContainerComponent
    id="container"
    ref={(scope) => {
      this.container = scope;
    }}
    height={'590px'}
    serviceUrl="https://ej2services.syncfusion.com/production/web-services/api/documenteditor/"
