GlobalEventHandlers.onmousewheel
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.
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.
Instead of using this event, 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 WheelEvent
interface.
See the mousewheel event documentation for more information about the
event.
