Функция отображения изображений по щелчку на основе координат мыши

/ 17 февраля 2020

Пользователь должен щелкнуть в любом месте страницы, чтобы изображение всплыло в точных координатах того места, где пользователь нажимает на странице.

Все работает нормально, но я хочу, чтобы функция при нажатии работала НЕ ТОЛЬКО для области просмотра 100vh экрана, но для ДЛИНА ВСЕЙ СТРАНИЦЫ до пользователь достигает нижней части страницы.

Драгоценная помощь, чтобы исправить мой код? 

$(window).scroll(function () {
  var percent = $(document).scrollTop() / ($('body').height() / 3);
  $('#scrollDown').css('opacity', 1 - percent);
});

Поскольку они оба расположены абсолютно с правильными значениями z-index, вы можете добиться этого, перемещая div с классом .place-on-click внутри основной элемент и изменение цвета фона div на прозрачный.
