GlobalEventHandlers.onmousewheel
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.
The onmousewheel property sets and returns the event handler for the
mousewheel event.
Do not use this wheel event. This interface is non-standard and
deprecated. It was used in non-Gecko browsers only. Instead use the standard
wheel event.
Syntax
element.onmousewheel = handlerFunction;
var handlerFunction = element.onmousewheel;
handlerFunction should be either null or a JavaScript function
specifying the handler for the event.
Notes
See the DOM event handlers
page for information on working with on... handlers.
The mousewheel event is fired asynchronously when a mouse wheel or similar
device is operated. It's represented by the MouseWheelEvent
interface.
See the mousewheel event documentation for more information about the
event.
