MDN wants to learn about developers like you:


The Gamepad.axes property of the Gamepad interface returns an array representing the controls with axes present on the device (e.g. analog thumb sticks).-

Each entry in the array is a floating point value in the range -1.0 – 1.0, representing the axis position from the lowest value (-1.0) to the highest value (1.0).


readonly    attribute double[]            axes;


function gameLoop() {
  if(navigator.webkitGetGamepads) {
    var gp = navigator.webkitGetGamepads()[0];
  } else {
    var gp = navigator.getGamepads()[0];

  if(gp.axes[0] != 0) {
    b -= gp.axes[0];
  } else if(gp.axes[1] != 0) {
    a += gp.axes[1];
  } else if(gp.axes[2] != 0) {
    b += gp.axes[2];
  } else if(gp.axes[3] != 0) {
    a -= gp.axes[3];
  } = a*2 + "px"; = b*2 + "px";

  var start = rAF(gameLoop);


An array of double values.
