Javascript to trigger multiple elements in Storyline

with

document.querySelectorAll

you get a list (array) of results, but this function

TopButton.addEventListener

don't work with lists, only for a single result

here is a version, which works for one and multiple search results

var player = GetPlayer();
var TopButtons = document.querySelectorAll("[data-acc-text='ImmEnroll']");

TopButtons.forEach( item => {
  item.addEventListener('mouseup', MouseUpHandler )
});
  
function MouseUpHandler( event ) {
  console.log( event );
  alert("Mouse");
}
