Detect when user scrolled down and reached center of page

Question

Currently I have the following code which detects when a user has started scrolling and if they\'ve reached the center of the page.

$(window).scroll(function() {         


        

Answer 1

Try this

$(document).on("scroll.y", function(e) {
  if ($("body").scrollTop() >= ( ($(e.target).height() / 2) -250) ) {
       console.log("approximate center"); $(e.target).off("scroll.y")
  };
  return false
})
