DevExtreme jQuery/JS - Keyboard Support

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

Key Action
Alt + ↓ Opens the drop-down list.
Alt + ↑ Closes the drop-down list.
Esc Closes the drop-down list and removes focus from the widget.
↑ / ↓ If the drop-down list is opened, moves focus to the previous/next item; otherwise, selects the previous/next item.
Page Up / Page Down Moves focus to the first/last item.
Enter or Space Selects the item.

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

JavaScript
  • function registerKeyHandlers () {
  • const selectBox = $("#selectBoxContainer").dxSelectBox("instance");
  • selectBox.registerKeyHandler("backspace", function(e) {
  • // The argument "e" contains information on the event
  • });
  • selectBox.registerKeyHandler("space", function(e) {
  • // ...
  • });
  • }
