import { DocumentEditorContainer, Toolbar, CustomContentMenuEventArgs } from '@syncfusion/ej2-documenteditor';
import { MenuItemModel } from '@syncfusion/ej2-navigations';

DocumentEditorContainer.Inject(Toolbar);

let container: DocumentEditorContainer = new DocumentEditorContainer({ enableToolbar: true, height: '590px' });

container.serviceUrl = 'https://ej2services.syncfusion.com/production/web-services/api/documenteditor/';

container.appendTo('#container');

//Creating custom menu items
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);
//To handle contextmenu select event
container.documentEditor.customContextMenuSelect = (args: CustomContentMenuEventArgs): void => {
    let item: string = args.id;
    let id: string = container.documentEditor.element.id;
    switch (item) {
        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;
    }
};

// Insert bookmark to selected content
