How to use window.scroll with horizontal scroll to get element position

I'm trying to get element position while scrolling in a horizontal web page. I tried to use

main scrolling:

$('html, body, *').mousewheel(function(e, delta) {
this.scrollLeft -= (delta*60);
});

then:

  $(window).scroll(function() {
    alert('Anything');
  });

But that doesn't work at all. I tried using mousewheel plugin

$('.internal.th').on('mousewheel',function(event) {
  console.log(event.deltaX, event.deltaY, event.deltaFactor);
});

But it keeps displaying the same position -0 -1 100 no matter how much i scroll

I tried

$('.internal.th').on('scroll', function() {
  var val = $(this).scrollLeft()
  if (val >= 100) alert('Hello')

})

but it doesn't do anything at all

The idea is getting some item position from the left related to the window to manage another element rotation so I want to keep tracking the main item positing while scrolling horizontally not vertically

Solution

  • jQuery provides APIs

    offset
    position

    you can use those

    Below is a sample with both vertical and horizontal scrollbars

    $(document).ready(function(){
	document.addEventListener('scroll', function (event) {
          console.log(event.target);
          console.log($("#p3").position());
          console.log($("#p3").offset());
          console.log($("#p3").position().top - $("body").scrollTop());
          console.log($("#p3").position().left - $("body").scrollLeft());
	}, true);
  });
