Use the registerKeyHandler(key, handler) method to implement a custom handler for a key.

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

Screen Reader Support

The DateRangeBox component supports screen readers and complies to WAI-ARIA standards.

To improve accessibility, use the startDateInputAttr and endDateInputAttr properties to specify aria-label for the component. You do not need to specify aria-label if you use startDateLabel or endDateLabel correspondingly.
