DevExtreme Vue - Keyboard Support

An end user can use the following keys to interact with the widget.

Key Action
Enter or Space Changes the widget value.
Changes the switch state to "On".
Changes the switch state to "Off".

You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.

jQuery
JavaScript
function registerKeyHandlers () {
    let switch =  $("#switchContainer").dxSwitch("instance");
    switch.registerKeyHandler("backspace", function (e) {
        // The argument "e" contains information on the event
    });
    switch.registerKeyHandler("space", function (e) {
        // ...
    });
}
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from '@angular/core';
import { DxSwitchModule, DxSwitchComponent } from 'devextreme-angular';
// ...
export class AppComponent implements AfterViewInit {
    @ViewChild(DxSwitchComponent) switch: DxSwitchComponent
    ngAfterViewInit () {
        this.switch.instance.registerKeyHandler("backspace", function (e) {
            // The argument "e" contains information on the event
        });
        this.switch.instance.registerKeyHandler("space", function (e) {
            // ...
        });
    }
}
@NgModule({
    imports: [
        // ...
        DxSwitchModule
    ],
    // ...
})
