  • BATTERY STATUS API
  • BATTERY STATUS API var battery = navigator.battery; if (battery) { var batteryLevel = Math.round(battery.level * 100) + "%", charging = (battery.charging)? "" : "not ", chargingTime = parseInt(battery.chargingTime / 60, 10), dischargingTime = parseInt(battery.dischargingTime / 60, 10); // Set events battery.addEventListener("levelchange", setStatus, false); battery.addEventListener("chargingchange", setStatus, false); battery.addEventListener("chargingtimechange", setStatus, false); battery.addEventListener("dischargingtimechange", setStatus, false); }
  • VIBRATION API
  • VIBRATION API // Vibrate for one second navigator.vibrate(1000); // Vibration pattern [vibrationTime, pause,] navigator.vibrate([200, 100, 200, 100]); // Vibrate for 5 seconds navigator.vibrate(5000); // Turn off vibration navigator.vibrate(0);
  • NETWORK INFORMATION API
  • NETWORK INFORMATION API var connection = window.navigator.mozConnection, online = connection.bandwidth > 0, metered = connection.metered;
  • PAGE VISIBILITY
  • PAGE VISIBILITY document.addEventListener("visibilitychange", function () { if (document.hidden) { console.log("App is hidden"); } else { console.log("App has focus"); } });
