Definition and Usage

The scrollstart event is triggered when the user starts to scroll the page.

Note: iOS devices freeze DOM manipulation during scrolls, which means that it is not possible to change something when the user scrolls. However, the jQuery team are working on a solution for this.

Tip: This event is often attached to the document.

Tip: The scrollstop event is triggered when the user stops to scroll the page.


Syntax

Parameter Description
