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.
Syntax
readonly attribute long index;
Example
window.addEventListener("gamepadconnected", function() {
var gp = navigator.getGamepads()[0];
gamepadInfo.innerHTML = "Gamepad connected at index " + gp.index + ": " + gp.id + ".";
});
Value
An integer.
