Angular Slider - Keyboard Support

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

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.

  • <template>
  • <DxSlider :ref="mySliderRef" />
  • </template>
  • <script>
  • import 'devextreme/dist/css/dx.light.css';
  •

  •  
  • const mySliderRef = 'my-slider';
  •  
  • export default {
  • components: {
  • DxSlider
  • },
  • data() {
  • return {
  • mySliderRef
  • }
  • },
  • computed: {
  • slider: function() {
  • return this.$refs[mySliderRef].instance;
  • }
  • },
  • mounted: function() {
  • this.slider.registerKeyHandler('backspace', function(e) {
  • // The argument "e" contains information on the event
  • });
  • this.slider.registerKeyHandler('space', function(e) {
  • // ...
  • });
  • }
  • }
