利用html5實現相似微信的手機搖一搖功能,並播放音樂。javascript
一、 deviceOrientation:封裝了方向傳感器數據的事件,能夠獲取手機靜止狀態下的方向數據,例如手機所處角度、方位、朝向等。css
二、 deviceMotion:封裝了運動傳感器數據的事件,能夠獲取手機運動狀態下的運動加速度等數據。html
js以下:html5
<scirpt> var SHAKE_THRESHOLD = 3000; var last_update = 0; var x = y = z = last_x = last_y = last_z = 0; function init() { if (window.DeviceMotionEvent) { window.addEventListener('devicemotion', deviceMotionHandler, false); } else { alert('not support mobile event'); } } function deviceMotionHandler(eventData) { var acceleration = eventData.accelerationIncludingGravity; var curTime = new Date().getTime(); if ((curTime - last_update) > 100) { var diffTime = curTime - last_update; last_update = curTime; x = acceleration.x; y = acceleration.y; z = acceleration.z; var speed = Math.abs(x + y + z - last_x - last_y - last_z) / diffTime * 10000; if (speed > SHAKE_THRESHOLD) {//一檢測到搖動了,就5秒後跳轉(此期間播放搖一搖的聲音) alert("搖動了"); media.setAttribute("src", "http://dx.sc.chinaz.com/files/download/sound1/201410/5018.wav"); media.load(); media.play(); setTimeout(function(){location.href='http://www.baidu.com';},5000);} } last_x = x; last_y = y; last_z = z; } } </script>
