Gamepad: index property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2017.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The Gamepad.index property of the Gamepad
interface returns an integer that is auto-incremented to be unique for each device
currently connected to the system.
This can be used to distinguish multiple controllers; a gamepad that is disconnected and reconnected will retain the same index.
Value
A number.
Examples
js
window.addEventListener("gamepadconnected", () => {
const gp = navigator.getGamepads()[0];
gamepadInfo.textContent = `Gamepad connected at index ${gp.index}: ${gp.id}.`;
});
