XRSession: selectend event
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The WebXR event selectend
is sent to an XRSession
when one of its input sources ends its primary action or when an input source that's in the process of handling an ongoing primary action is disconnected without successfully completing the action.
The beforexrselect
is fired before this event and can prevent this event from being raised.
Syntax
Use the event name in methods like addEventListener()
, or set an event handler property.
js
addEventListener("selectend", (event) => {});
onselectend = (event) => {};
Event type
An XRInputSourceEvent
. Inherits from Event
.
Event properties
In addition to the properties listed below, properties from the parent interface, Event
, are available.
frame
Read only-
An
XRFrame
object providing the needed information about the event frame during which the event occurred. This frame may have been rendered in the past rather than being a current frame. Because this is an event frame, not an animation frame, you cannot call theXRFrame
methodgetViewerPose()
on it; instead, usegetPose()
. inputSource
Read only-
An
XRInputSource
object indicating which input source generated the input event.
Description
Trigger
Triggered when the user stops to press triggers or buttons, taps a touchpad, speaks a command, or performs a recognizable gesture when using a video tracking system or handheld controller with an accelerometer.
Use cases
The selectend
and selectstart
events tell you when you might want to display something to the user indicating that the primary action is going on. This might be drawing a controller with the activated button in a new color, or showing the targeted object being grabbed and moved around, starting when selectstart
arrives and stopping when selectend
is received.
The select
event is the event that tells your code that the user has completed the action they want to complete. This might be as simple as throwing an object or pulling the trigger of a gun in a game, or as involved as placing a dragged object in a new location.
If your primary action is a simple trigger action and you don't need to animate anything while the trigger is engaged, you can ignore the selectstart
and selectend
events and act on the start event.
Examples
See the selectstart
event for example code.
