DevExtreme jQuery - 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, { static: false }) radioGroup: DxRadioGroupComponent
// Prior to Angular 8
// @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
],
// ...
