Accessibility Standards Compliance

The CheckBox component complies to all Section 508 and WCAG 2.x standards criteria.

Keyboard Navigation

A user can use the following keys to interact with the CheckBox component:

Key Action
Space Changes the UI component value.

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

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

Screen Reader Support

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

The CheckBox's aria label depends on the properties you use. If you specify the text or hint property, its value is copied to the aria-label. In other cases, use elementAttr to specify the aria-label directly.
