 /**
- * @file
- * Adds an HTML element and method to trigger audio UAs to read system messages.
- *
- * Use {@link Drupal.announce} to indicate to screen reader users that an
- * element on the page has changed state. For instance, if clicking a link
- * loads 10 more items into a list, one might announce the change like this.
- *
- * @example
- * $('#search-list')
- *   .on('itemInsert', function (event, data) {
- *     // Insert the new items.
- *     $(data.container.el).append(data.items.el);
- *     // Announce the change to the page contents.
- *     Drupal.announce(Drupal.t('@count items added to @container',
- *       {'@count': data.items.length, '@container': data.container.title}
- *     ));
