首先對(duì)DeviceMotionEvent進(jìn)行優(yōu)化；

去除無(wú)用的代碼，重新封裝DeviceMotionEven

復(fù)制代碼代碼如下:

if(window.DeviceMotionEvent) {

var speed = 25;//定義一個(gè)數(shù)值

var x = y = z = lastX = lastY = lastZ = 0;//重置所有數(shù)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(shí)現(xiàn)搖一搖之后所要進(jìn)行的數(shù)據(jù)邏輯操作

donghua();

}

lastX = x;

lastY = y;

lastZ = z;

}, false);

}

由于實(shí)際項(xiàng)目中有很多需求無(wú)法很好的實(shí)現(xiàn)，

比如：動(dòng)畫不執(zhí)行完畢就不能繼續(xù)執(zhí)行DeviceMotionEvent事件；

所以做了進(jìn)一步優(yōu)化；

復(fù)制代碼代碼如下:

var f=1;

function donghua(){

//動(dòng)畫事件

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

});

if(window.DeviceMotionEvent) {

var speed = 25;//定義一個(gè)數(shù)值

var x = y = z = lastX = lastY = lastZ = 0;//重置所有數(shù)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(shí)現(xiàn)搖一搖之后所要進(jìn)行的數(shù)據(jù)邏輯操作

if(f==1){

donghua();

f=0;

}

}

lastX = x;

lastY = y;

lastZ = z;

}, false);

}

現(xiàn)在就完美了
