DevExtreme React - Keyboard Support
An end user can use the following keys to interact with the widget.
Key | Action |
---|---|
↑ or Page Up | Moves focus to the previous radio button. |
↓ or Page Down | Moves focus to the next radio button. |
Home / End | Moves focus to the first/last radio button. |
Enter or Space | Selects the focused radio button. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
jQuery
JavaScript
function registerKeyHandlers () { let radioGroup = $("#radioGroupContainer").dxRadioGroup("instance"); radioGroup.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); radioGroup.registerKeyHandler("space", function (e) { // ... }); }
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from "@angular/core"; import { DxRadioGroupModule, DxRadioGroupComponent } from "devextreme-angular"; // ... export class AppComponent implements AfterViewInit { @ViewChild(DxRadioGroupComponent) radioGroup: DxRadioGroupComponent ngAfterViewInit () { this.radioGroup.instance.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); this.radioGroup.instance.registerKeyHandler("space", function (e) { // ... }); } } @NgModule({ imports: [ // ... DxRadioGroupModule ], // ... })
