[removed] How to detect if browser window is scrolled to bottom?

Question

I need to detect if a user is scrolled to the bottom of a page. If they are at the bottom of the page, when I add new content to the bottom, I will automatically scroll them

Answer 1

You can check if the combined result of the window's height and scroll top is bigger than that of the body

if (window.innerHeight + window.scrollY >= document.body.scrollHeight) {}
