Category: DOM
Type: New or changed feature
Status: In developer trial (Behind a flag) (Chrome 75)
Intent stage: Evaluate readiness to ship

Summary

Similar to scroll event, Chrome will send overscroll and scrollend DOM events.

Motivation

The overscroll and scrollend events will provide web developers a way to listen to the state of the scrolling and when their content is being overscrolled or when the scrolling has finished. This information will be useful for customization of effects such as overscroll affordance, pull to refresh, or history swipe navigations in the web apps.
