首先对DeviceMotionEvent进行优化；
去除无用的代码，重新封装DeviceMotionEven
if(window.DeviceMotionEvent) {
var speed = 25;//定义一个数值
var x = y = z = lastX = lastY = lastZ = 0;//重置所有数值
window.addEventListener('devicemotion', function(){
var acceleration =event.accelerationIncludingGravity;//将传感值赋给acceleration
x = acceleration.x;
y = acceleration.y;
z = acceleration.z;
if(Math.abs(x-lastX) > speed || Math.abs(y-lastY) > speed ) {
// TODO:在此处可以实现摇一摇之后所要进行的数据逻辑操作
donghua();
}
lastX = x;
lastY = y;
lastZ = z;
}, false);
}
由于实际项目中有很多需求无法很好的实现，
比如：动画不执行完毕就不能继续执行DeviceMotionEvent事件；
所以做了进一步优化；
var f=1;
function donghua(){
//动画事件
$(".img").animate({left:'0',opacity:'1'},700,function(){f=1;});
});
if(window.DeviceMotionEvent) {
var speed = 25;//定义一个数值
var x = y = z = lastX = lastY = lastZ = 0;//重置所有数值
window.addEventListener('devicemotion', function(){
var acceleration =event.accelerationIncludingGravity;//将传感值赋给acceleration
x = acceleration.x;
y = acceleration.y;
z = acceleration.z;
if(Math.abs(x-lastX) > speed || Math.abs(y-lastY) > speed ) {
// TODO:在此处可以实现摇一摇之后所要进行的数据逻辑操作
if(f==1){
donghua();
f=0;
}
}
lastX = x;
lastY = y;
lastZ = z;
}, false);
}
现在就完美了
