How to detect if user is scrolling with JavaScript?
To detect if user is scrolling with JavaScript, we can listen to the window’s scroll
event.
For instance, we write
let userHasScrolled = false;
window.onscroll = (e) => {
userHasScrolled = true;
};
to set window.onscroll
to a function that sets userHasScrolled
to true
when we scroll in the window.
Then if userHasScrolled
is true
, we know the user scrolled.
