Why is body.scrollTop deprecated?

Question

It seems body.scrollTop (and body.scrollLeft) are deprecated in ES5 strict-mode. What is the reason for this, given that it still seems okay to use

Answer 1

I noticed my code stop working on newer versions of Chrome. I fixed it by using window.scrollY

Before:

var scrollTop = document.body.scrollTop;

Now:

var scrollTop = window.scrollY;

It works all the time now. You can find more documentation here.

Also, I was using:

document.body.scrollTop = 0;

now I replaced it with:

window.scrollTo(0, 0);
