javascript - Get scroll position and direction with vanilla JS -


I'm trying to complete a project without using jQuery. Looks good yet, but there is something I can not manage: scroll position and direction

What I basically want to do is to add an element to an element, when we reach a point, there is only one point, but going up.

I have a JSFiddle recently it helps you to do this Could. You need to include it to find out from scrolling, you can do this by handling the last scrollbar position and comparing it to one current.
