DevExtreme React - Keyboard Support
An end user can use the following keys to interact with the widget.
Key | Action |
---|---|
← / → | Decreases/increases the value of the focused handle by a step. |
Page Up / Page Down | Decreases/increases the value of the focused handle by a keyStep. |
Home / End | Sets the focused handle to the minimum/maximum value or to the value of the other handle. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
jQuery
JavaScript
function registerKeyHandlers () { let slider = $("#sliderContainer").dxSlider("instance"); slider.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); slider.registerKeyHandler("space", function (e) { // ... }); }
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from "@angular/core"; import { DxSliderModule, DxSliderComponent } from "devextreme-angular"; // ... export class AppComponent implements AfterViewInit { @ViewChild(DxSliderComponent) slider: DxSliderComponent ngAfterViewInit () { this.slider.instance.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); this.slider.instance.registerKeyHandler("space", function (e) { // ... }); } } @NgModule({ imports: [ // ... DxSliderModule ], // ... })
