DevExtreme React - Keyboard Support
An end user can use the following keys to interact with the widget.
Key | Action |
---|---|
Alt + ↓ | Opens the drop-down list. |
Alt + ↑ | Closes the drop-down list. |
Esc | Closes the drop-down list and removes focus from the widget. |
↑ / ↓ | If the drop-down list is opened, moves focus to the previous/next item; otherwise, selects the previous/next item. |
Page Up / Page Down | Moves focus to the first/last item. |
Enter or Space | Selects the item. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
jQuery
JavaScript
function registerKeyHandlers () { let selectBox = $("#selectBoxContainer").dxSelectBox("instance"); selectBox.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); selectBox.registerKeyHandler("space", function (e) { // ... }); }
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from "@angular/core"; import { DxSelectBoxModule, DxSelectBoxComponent } from "devextreme-angular"; // ... export class AppComponent implements AfterViewInit { @ViewChild(DxSelectBoxComponent) selectBox: DxSelectBoxComponent ngAfterViewInit () { this.selectBox.instance.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); this.selectBox.instance.registerKeyHandler("space", function (e) { // ... }); } } @NgModule({ imports: [ // ... DxSelectBoxModule ], // ... })
