| Default action |
Scrolls the contents of an object until new portions of the object become visible. |
A scroll event fires whenever the scroll box is repositioned in the scroll bar.
Programmatic control of scroll bar components is provided by the componentFromPoint and doScroll methods.
CSS enables scrolling on all objects through the overflow property. Such objects are not listed in the Applies To list for this event.
While event handlers in the Document Object Model do not receive parameters directly, the handler can query the event object for data.
