DevExtreme jQuery/JS - Keyboard Support

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

Key Action
↑ or mouse wheel up Increases the widget value by a step.
↓ or mouse wheel down Decreases the widget value by a step.

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

JavaScript
  • function registerKeyHandlers () {
  • let numberBox = $("#numberBoxContainer").dxNumberBox("instance");
  • numberBox.registerKeyHandler("backspace", function (e) {
  • // The argument "e" contains information on the event
  • });
  • numberBox.registerKeyHandler("space", function (e) {
  • // ...
  • });
  • }
