Accessibility Standards Compliance
The Popup 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 Popup component:
Key | Action |
---|---|
↑ → ↓ ← | Drags the popup when it is focused and dragEnabled is true. |
Esc | Closes the popup. |
Use the registerKeyHandler(key, handler) method to implement a custom handler for a key.
- function registerKeyHandlers () {
- const popup = $("#popupContainer").dxPopup("instance");
- popup.registerKeyHandler("backspace", function(e) {
- // The argument "e" contains information on the event
- });
- popup.registerKeyHandler("space", function(e) {
- // ...
- });
- }
Screen Reader Support
The Popup component supports screen readers and complies to WAI-ARIA standards.
The default Popup ARIA role is the non-modal dialog. If you use Popup as a modal, enable the aria-modal attribute as follows:
- const popup = $('#popup').dxPopup({
- // ...
- onShowing: function (e) {
- var $overlayContent = $(e.component.content()).parent()
- $overlayContent.attr("aria-modal", "true");
- },
- }).dxPopup('instance');
You can also use this method to specify aria-label for the component:
- const popup = $('#popup').dxPopup({
- // ...
- onShowing: function (e) {
- var $overlayContent = $(e.component.content()).parent()
- $overlayContent.attr("aria-label", "Dialog window");
- },
- }).dxPopup('instance');
