利用html5实现类似微信的手机摇一摇功能,并播放音乐。
1、 deviceOrientation:封装了方向传感器数据的事件,可以获取手机静止状态下的方向数据,例如手机所处角度、方位、朝向等。
2、 deviceMotion:封装了运动传感器数据的事件,可以获取手机运动状态下的运动加速度等数据。
js如下:
<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) {//一检测到摇动了,就5秒后跳转(此期间播放摇一摇的声音) alert("摇动了"); 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>
html5页面如下:

在手机上试试....
