Screen Reader Support

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

To improve accessibility, use the elementAttr property to specify aria-label for the component.

Not all screen readers pronounce the progress status. To make sure the status is pronounced, add the following aria-* attributes:

index.js
  • $(function(){
  • $("#progressBarContainer").dxProgressBar({
  • elementAttr: {
  • 'aria-live': 'polite',
  • 'aria-describedby': 'status',
  • },
  • onContentReady: ({ element }) => {
  • $(element).find('.dx-progressbar-status').attr('id', 'status');
  • }
  • });
  • });
