Scrolled : a generic scroll event
Scrolled : a really simple generic scroll event with the previous scroll value and the current scroll value. So at the end, one scroll event to used into multiple behaviors.
In your behavior js file :
function _handleScroll(event) {
prevScrollPos = event.data.prev;
lastScrollPos = event.data.last;
console.log('Scrolling up or down ?')
console.log(prevScrollPos);
console.log(lastScrollPos);
}
document.addEventListener('scrolled', _handleScroll);
In your app.js file :
scrolled();
