onmsgestureend event

Artigo
05/02/2017

This event fires when all associated contacts are removed from the surface, and any inertia related movements have stopped..

Syntax

HTML Attribute	<element onmsgestureend = "handler(event)">
addEventListener Method	object.addEventListener("MSGestureEnd", handler, useCapture)

Event handler parameters

handler [in]
Type: Function

Function name to execute when a gesture has ended.

Remarks

When contacts are removed from a surface, the gesture is then processed by the target object, including any movement that occurs after an onmsinertiastart event. The onmsgestureend event fires after the gesture has been completely processed.
