我如何检测是否有人尝试滚动，即使这是不可能的？

$(document).ready(function() {
  $('.scrollable-area').on('wheel', function(e) {
    var scrollLeft = $(this).scrollLeft();
    var width = $(this).get(0).scrollWidth - $(this).width();
    var deltaY = e.originalEvent.deltaY;
    var deltaX = e.originalEvent.deltaX;
    var newScrollLeft = scrollLeft + deltaY + deltaX;
    if ((deltaY > 0 && newScrollLeft < width) ||
      (deltaY < 0 && newScrollLeft > 0)) {
      e.preventDefault();
    }
    if (newScrollLeft <= 0) {
      $(this).scrollLeft(0);
    } else if (newScrollLeft >= width) {
      $(this).scrollLeft(width);
    } else {
      $(this).scrollLeft(newScrollLeft);
    }
  });
});

$('.scrollable-area').on("mousedown touchstart", function() {
  $('iframe').css('pointer-events', 'all');
});

$('.scrollable-area').scroll(function() {
  $('iframe').css('pointer-events', 'none');
});

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

.gallery-container {
  position: relative;
  width: 100%;
  height: 90vh;
  background-color: yellow;
  overflow: hidden;
}

.scrollable-area {
  width: 100%;
  height: 100%;
  overflow-x: auto;
}

.gallery-items {
  display: flex;
  min-width: 100%;
  height: 100%;
}

.gallery-item {
  flex: 0 0 auto;
  height: 100%;
  display: flex;
}

.gallery-item img {
  max-width: 100%;
  height: auto;
  object-fit: contain;
}

.gallery-item iframe {
  background-color: blue;
  width: calc(100% * 1.75);
  width: calc((16 / 9) * 90vh);
  pointer-events: none;
}
