The inputsourceschange event is sent to an XRSession when the set of available WebXR input devices changes.
Syntax
Use the event name in methods like addEventListener(), or set an event handler property.
addEventListener("inputsourceschange", (event) => { })
oninputsourceschange = (event) => { }
Event type
An XRInputSourcesChangeEvent. Inherits from Event.
Description
Trigger
Triggered when the set of available WebXR input devices changes.
Use cases
You can use this event to detect newly-available devices or when devices have become unavailable.
Examples
The following example shows how to set up an event handler which uses inputsourceschange events to detect newly-available pointing devices and to load their models in preparation for displaying them in the next animation frame.
xrSession.addEventListener("inputsourceschange", onInputSourcesChange);
function onInputSourcesChange(event) {
for (const input of event.added) {
if (input.targetRayMode === "tracked-pointer") {
loadControllerMesh(input);
}
}
}
You can also add a handler for inputsourceschange events by setting the oninputsourceschange event handler:
xrSession.oninputsourceschange = onInputSourcesChange;
