How to get scrollY position of a scrollable popup

Question

While scrolling a scrollable div on a pop-up, I need the y coordinates, using window.scrollY return y coordinates of background body, not of popup. Is there any way to achieve this?

Answer 1

Just add a scroll event to the element which is scrollable.

const div = document.getElementById("myDiv");
div.addEventListener("scroll", (e)=> {
  console.log("scrollTop: " + e.scrollTop);
});
