Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
Deprecated
This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
The MouseScrollEvent interface represents events that occur due to the user moving a mouse wheel or similar input device.
Do not use this interface for wheel events.
Like MouseWheelEvent, this interface is non-standard and deprecated. It was used in Gecko-based browsers only. Instead use the standard WheelEvent.
