Gamepad: displayId property

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

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 display's pose, see VRDisplay.getPose().

Note: This property was part of the old WebVR API. It has been superseded by the WebXR Gamepads Module.

There is no direct replacement for this property. The Gamepad object associated with an XRInputSource can be obtained using the XRInputSource.gamepad property.

Value

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

Examples

js

window.addEventListener("gamepadconnected", (e) => {
  if (!e.gamepad.displayId) {
    console.log("Gamepad connected");
  } else {
    console.log(
      `Gamepad connected, associated with VR display ${e.gamepad.displayId}`,
    );
  }
});

Specifications

This property was part of the old WebVR API that has been superseded by the WebXR Gamepads Module. It is no longer on track to becoming a standard.

Until all browsers have implemented the new WebXR APIs, it is recommended to rely on frameworks, like A-Frame, Babylon.js, or Three.js, or a polyfill, to develop WebXR applications that will work across all browsers [1].
