Show completed text for screen readers on explore pages. When a an explore button is clicked, this appends some text to the explore button. The text should instruct screen reader users that they have already interacted with the button/popup.

exploreAAfix.html

<script>

     $(document).ready(function () {

        T2.CreateButton.prototype.run = (function(_super) {

            return function() {
                
                // This adds some visually hidden text for screen readers.
                // Change the text so it makes sense in context with your explore page
                if(!this.completed)
                    this.elements.link[0].innerHTML += ' <span class="visuallyhidden">completed</span>';

                return _super.apply(this);
            };
                    

        })(T2.CreateButton.prototype.run);

    });
</script>

If the function has an argument, then you need to pass it to apply() in an array:

T2.page.popup.open = (function(_super) {
    return function(popupNumber) {

      debugger;
        return _super.apply(this,[popupNumber]);
    };

  })(T2.page.popup.open);
