對DeviceMotionEvent進行優化,除無用的代碼重新封裝DeviceMotionEven,另外動畫不執行完畢就不能繼續執行DeviceMotionEvent事件,所以這點也要進行優化
首先對DeviceMotionEvent進行優化;
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後所要進行的數據邏輯操作
donghua();
}
lastX = x;
lastY = y;
lastZ = z;
}, false);
}
由於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;
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後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
