The beforexrselect
event is fired before WebXR select events (select
, selectstart
, selectend
) are dispatched. It can be used to suppress XR world input events while the user is interacting with a DOM overlay UI.
This event bubbles, is cancelable and is composed.
Use the event name in methods like addEventListener()
, or set an event handler property.
addEventListener("beforexrselect", (event) => {});
onbeforexrselect = (event) => {};
The beforexrselect
event is a global event and available to the following interfaces:
To suppress WebXR select events (select
, selectstart
, selectend
), an application can listen for the beforexrselect
event. The event bubbles, so a call to preventDefault()
on the DOM overlay element will prevent any WebXR select events within this container allowing interaction with the DOM element and avoiding duplicate event input to the XR world.

.getElementById("xr-overlay")
.addEventListener("beforexrselect", (ev) => ev.preventDefault());
