Javascript 移动加速计和陀螺仪检查功能

我正在寻找一种合适的方法来检查移动设备（主要是android和iphone）上是否有javascript格式的加速计和陀螺仪

也许通过尝试确定调用的函数是否返回了某些内容？

您可以尝试以下方法：

if (window.DeviceMotionEvent) {
  window.addEventListener('devicemotion', deviceMotionHandler, false);
} else {
  // This device doesn't support accelerators
}

function deviceMotionHandler(e) {
    var acceleration = e.accelerationIncludingGravity;
    var accelerationX = acceleration.x;
    var accelerationYe.acceleration.y;
    var accelerationZ = acceleration.z;

    if (e.rotationRate) {
      var rotation = e.rotationRate;
      var rotationAlpha = rotation.alpha;
      var rotationBeta = rotation.beta;
      var rotationGamma = rotation.gamma;
    }
}

这篇文章将进一步阐明这个问题。
