[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

Two solutions I found that worked for me:

  window.addEventListener('scroll', function(e) {
    if (
      window.innerHeight + document.documentElement.scrollTop ===
      document.documentElement.offsetHeight
    ) {
      console.log('You are at the bottom')
    }
  })

And the other:

  window.addEventListener('scroll', function(e) {
    if (
      window.innerHeight + window.pageYOffset ===
      document.documentElement.offsetHeight
    ) {
      console.log('You are at the bottom')
    }
  })
