When a gamepad is connected, this example reports its index, id, number of buttons, number of axes, and when the gamepad data was updated.

window.addEventListener("gamepadconnected", function(e) {
  var gp = navigator.getGamepads()[e.gamepad.index];
  console.log("Gamepad connected.");
  console.log("Gamepad index:", gp.index);
  console.log("Gamepad id:", gp.id);
  console.log("Gamepad buttons:", gp.buttons.length);
  console.log("Gamepad axes:", gp.axes.length);
  console.log("Gamepad last updated:", gp.timestamp);
});
