DevExtreme jQuery - 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 menu = $("#menuContainer").dxMenu("instance");
menu.registerKeyHandler("backspace", function (e) {
// The argument "e" contains information on the event
});
menu.registerKeyHandler("space", function (e) {
// ...
});
}Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from "@angular/core";
import { DxMenuModule, DxMenuComponent } from "devextreme-angular";
// ...
export class AppComponent implements AfterViewInit {
@ViewChild(DxMenuComponent, { static: false }) menu: DxMenuComponent
// Prior to Angular 8
// @ViewChild(DxMenuComponent) menu: DxMenuComponent
ngAfterViewInit () {
this.menu.instance.registerKeyHandler("backspace", function (e) {
// The argument "e" contains information on the event
});
this.menu.instance.registerKeyHandler("space", function (e) {
// ...
});
}
}
