DevExtreme React - Keyboard Support
An end user can use the following keys to interact with the widget.
Key | Action |
---|---|
Enter or Space | Identical to a click. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
jQuery
JavaScript
function registerKeyHandlers () { let button = $("#buttonContainer").dxButton("instance"); button.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); button.registerKeyHandler("space", function (e) { // ... }); }
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from '@angular/core'; import { DxButtonModule, DxButtonComponent } from 'devextreme-angular'; // ... export class AppComponent implements AfterViewInit { @ViewChild(DxButtonComponent) button: DxButtonComponent ngAfterViewInit () { this.button.instance.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); this.button.instance.registerKeyHandler("space", function (e) { // ... }); } } @NgModule({ imports: [ // ... DxButtonModule ], // ... })
