Screen Reader Support

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

The default ARIA role for Popover is tooltip. If you put focusable content inside Popover, you may want to change the role to dialog. To implement this functionality, use the onShowing event handler:

index.js
  • const popover = $('#popover').dxPopover({
  • // ...
  • onShowing: function (e) {
  • var $overlayContent = $(e.component.content()).parent()
  • $overlayContent.attr("role", "dialog");
  • },
  • }).dxPopover('instance');

Accessibility readers do not notify users when the Popover is opened since it is not a focusable element. To receive reader notifications for an open dialog, programmatically focus an element in Popover after its activation:

index.js
  • $('#popover').dxPopover({
  • // ...
  • contentTemplate: () => '<div id="content" tabIndex="1">Content template</div>',
  • onShown: function (e) {
  • $('#content').focus();
  • },
  • });
