如何仅在没有jquery的情况下开始向下滚动角度时如何显示滚动到顶部按钮

Question

I'm trying to do it using a custom directive for that element and manipulate in the link function but I don't know how to proceed. Can we do it using pure javascript or any other library except jquery since people say 'no jquery in angular apps please' for some reason.

Answer 1

Found out Javascript has some inbuilt functions like .onscroll, .scrollY, .scroll which can be used to achieve the aforementioned functionality. I think a search into javascript in-built functions will get most of the stuff done before moving onto jquery.
