<script>
  if (location.protocol != 'https:') {
   location.href = 'https:' + window.location.href.substring(window.location.protocol.length);
  }
 
function requestT () {
      if (typeof(DeviceMotionEvent) !== 'undefined' && typeof(DeviceMotionEvent.requestPermission) === 'function') {
          
          DeviceMotionEvent.requestPermission()
          .then(response => {
    alert('Orientation tracking '+ response);
          
            if (response == 'granted') {
              window.addEventListener('devicemotion', (e) => {
               document.getElementById('request').style.visibility='hidden';
              })
            }
          })
      .catch(console.error)
      }else {
          alert('DeviceMotionEvent is not defined');
      }

  }
  document.getElementById('request').onclick = requestT;
