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;
}
}

在手机上试试....
