首先對DeviceMotionEvent進行優化；
去除無用的代碼，重新封裝DeviceMotionEven
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；
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
