The onselectstart attribute of the XRSession object is the event handler for the selectstart event, which is dispatched when user starts making some sort of selection by pressing a trigger, touchpad, or button, speaking a command, or making a hand gesture. For example, this might include pressing a button or moving a joystick.

Note: Not to be confused with XRSession.onselect and XRSession.onselectend.


XRSession.onselectstart = function(event) { ... }


XRSession.onselectstart = function(event) {
  console.log("The user has started a primary action, but might not have completed it.")
