Reply To: How to use jQuery to capture mouse scrolling

[nkrisc]

Here’s something I whipped together that seems to accomplish what you want. There might be a better way so if there is, hopefully someone else can help with that.

$(document).scroll(function(){
  if($(document).scrollTop() <= 1){
    $('body').css('background','red'); //what happens when you leave top
  }
  if($(document).scrollTop() === 0){
    $('body').css('background','green'); //what happens when you're back at top
  }
});

Just know that the event for when you’re back at the top won’t trigger on page load is it only check if you’re at the top while scrolling.
