This article mainly introduces the html5 shake code optimization method related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe that everyone after reading this html5 shake code optimization method article will have a harvest, let's take a look at it.
The code is as follows:
If (window.DeviceMotionEvent) {
Var speed = 25 position / define a numeric value
Var x = y = z = lastX = lastY = lastZ = 0 position / reset all values
Window.addEventListener ('devicemotion', function () {
Var acceleration = event.accelerationIncludingGravity;// assigns the sensing value to acceleration
X = acceleration.x
Y = acceleration.y
Z = acceleration.z
If (Math.abs (x-lastX) > speed | | Math.abs (y-lastY) > speed) {
/ / TODO: the data logic operation to be performed after shaking can be realized here
Donghua ()
}
LastX = x
LastY = y
LastZ = z
}, false)
}
Because there are many requirements in the actual project that can not be well implemented.
For example, you cannot continue to execute DeviceMotionEvent events until the animation is finished.
So further optimization has been made.
Copy the code
The code is as follows:
Var frank1
Function donghua () {
/ / Animation event
$(".img") .animate ({left:'0',opacity:'1'}, 700 focus function () {frank1;})
});
If (window.DeviceMotionEvent) {
Var speed = 25 position / define a numeric value
Var x = y = z = lastX = lastY = lastZ = 0 position / reset all values
Window.addEventListener ('devicemotion', function () {
Var acceleration = event.accelerationIncludingGravity;// assigns the sensing value to acceleration
X = acceleration.x
Y = acceleration.y
Z = acceleration.z
If (Math.abs (x-lastX) > speed | | Math.abs (y-lastY) > speed) {
/ / TODO: the data logic operation to be performed after shaking can be realized here
If (frank1) {
Donghua ()
Frank0
}
}
LastX = x
LastY = y
LastZ = z
}, false)
}
