DevExtreme jQuery/JS - Keyboard Support
An end user can use the following keys to interact with the widget.
Key | Action |
---|---|
← | Closes the submenu and focuses on its parent item. |
→ | Opens the submenu of the focused item. |
Home | Sets focus to the first item in the menu/submenu. |
End | Sets focus to the last item in the menu/submenu. |
Space | Switches the focused item to the selected state. |
Enter | Chooses the focused item. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
jQuery
JavaScript
function registerKeyHandlers () { let contextMenu = $("#contextMenuContainer").dxContextMenu("instance"); contextMenu.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); contextMenu.registerKeyHandler("space", function (e) { // ... }); }
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from "@angular/core"; import { DxContextMenuModule, DxContextMenuComponent } from "devextreme-angular"; // ... export class AppComponent implements AfterViewInit { @ViewChild(DxContextMenuComponent) contextMenu: DxContextMenuComponent ngAfterViewInit () { this.contextMenu.instance.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); this.contextMenu.instance.registerKeyHandler("space", function (e) { // ... }); } } @NgModule({ imports: [ // ... DxContextMenuModule ], // ... })
