The WebXR event select
is sent to an XRSession
when one of the session's input sources has completed a primary action. Examples of comon kinds of primary action are users pressing triggers or buttons, tapping a touchpad, speaking a command, or performing a recognizable gesture when using a video tracking system or handheld controller with an accelerometer.

events work, and how you should react to them, see Primary actions in Inputs and input sources.
Examples
The following example uses addEventListener()
to set up a handler for the select
event. The handler fetches the pose representing the target ray for tracked-pointer
inputs and sends the pose's transform to a function called myHandleSelectWithRay()
.
xrSession.addEventListener("select", event => { if (event.inputSource.targetRayMode == "tracked-pointer") { let targetRayPose = event.frame.getPose(event.inputSource.targetRaySpace, myRefSpace); if (targetRayPose) { myHandleSelectWithRay(targetRayPose.transform); } } });
You can of course also set up a handler for select
events by setting the XRSession
object's onselect
event handler property to a function that handles the event:
xrSession.onselect = event => { if (event.inputSource.targetRayMode == "tracked-pointer") { let targetRayPose = event.frame.getPose(event.inputSource.targetRaySpace, myRefSpace); if (targetRayPose) { myHandleSelectWithRay(targetRayPose.transform); } } };
