首先對DeviceMotionEvent進行優化；

去除無用的代碼，重新封裝DeviceMotionEven

代碼如下:

if(window.DeviceMotionEvent) {

var speed = 25;//定義一個數值

var x = y = z = lastX = lastY = lastZ = 0;//重置所有數值

window.addEventListener('devicemotion', function(){

var acceleration =event.accelerationIncludingGravity;//將傳感值賦給acceleration

x = acceleration.x;

y = acceleration.y;

z = acceleration.z;

if(Math.abs(x-lastX) > speed || Math.abs(y-lastY) > speed ) {

// TODO:在此處可以實現搖一搖之后所要進行的數據邏輯操作

donghua();

}

lastX = x;

lastY = y;

lastZ = z;

}, false);

}

由于實際項目中有很多需求無法很好的實現，

比如：動畫不執行完畢就不能繼續執行DeviceMotionEvent事件；

所以做了進一步優化；

代碼如下:

var f=1;

function donghua(){

//動畫事件

$(".img").animate({left:'0',opacity:'1'},700,function(){f=1;});

});

if(window.DeviceMotionEvent) {

var speed = 25;//定義一個數值

var x = y = z = lastX = lastY = lastZ = 0;//重置所有數值

window.addEventListener('devicemotion', function(){

var acceleration =event.accelerationIncludingGravity;//將傳感值賦給acceleration

x = acceleration.x;

y = acceleration.y;

z = acceleration.z;

if(Math.abs(x-lastX) > speed || Math.abs(y-lastY) > speed ) {

// TODO:在此處可以實現搖一搖之后所要進行的數據邏輯操作

if(f==1){

donghua();

f=0;

}

}

lastX = x;

lastY = y;

lastZ = z;

}, false);

}

現在就完美了
