首先對DeviceMotionEvent進行優(yōu)化；
    去除無用的代碼，重新封裝DeviceMotionEven
    復制代碼代碼如下:
    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(zhí)行完畢就不能繼續(xù)執(zhí)行DeviceMotionEvent事件；
    所以做了進一步優(yōu)化；
    復制代碼代碼如下:
    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
