如何使用jQuery滚动(元素的底部应该在页面的底部)

<script src="https://cdn.jsdelivr.net/npm/jquery/dist/jquery.min.js"></script>

function scrollToBottom(element) {
  var windowHeight = $(window).height();
  var elementHeight = $(element).outerHeight();
  var scrollHeight = $(document).height() - windowHeight;
  var elementOffset = $(element).offset().top;

  if (elementOffset > scrollHeight) {
    elementOffset = scrollHeight;
  }

  $('html, body').animate({
    scrollTop: elementOffset - windowHeight + elementHeight
  }, 500);
}

$('#scrollButton').click(function() {
  scrollToBottom('#elementToScroll');
});
