MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

Gamepad.displayId

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The displayId read-only property of the Gamepad interface returns the VRDisplay.displayId of the associated VRDisplay — the VRDisplay that the gamepad is controlling the displayed scene of.

A Gamepad is considered to be associated with a VRDisplay if it reports a pose that is in the same space as the VRDisplay.pose.

Syntax

var myDisplayId = gamepadInstance.displayId;

Value

A number representing the associated VRDisplay.displayId. If the number is 0, then the gamepad is not associated with a VR display.

Examples

window.addEventListener("gamepadconnected", function(e) {
  if(!e.gamepad.displayId) {
    console.log('Gamepad connected');
  } else {
    console.log('Gamepad connected, associated with VR display ' + e.gamepad.displayId);
  }
});
