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 gesturechange event is fired when digits move during a touch gesture.
It is a proprietary event specific to WebKit.
Use the event name in methods like addEventListener(), or set an event handler property.
js
addEventListener("gesturechange", (event) => {}); ongesturechange = (event) => {};
