廢話不多說了，直接給大家貼代碼了，具體代碼如下所示：
var Shaker = function(f){
// 搖一搖: 檢測到3次搖動算一次搖一搖, 搖動後調用處理函數, 不再檢測搖動
// f 搖動後的回調
this.callback = f;
this.status = 0; // 0: 偵聽未開始 1: 偵聽開始
this.speed = 15;
this.lastX = this.lastY = this.lastZ = 0;
this.num = 0; // 檢測觸發次數
this.minNum = 3; // 最小檢測觸發次數
this.beginSecond = 0; // 開始檢測的秒數
this.maxSecond = 3; // 最大間隔秒數
this.handlerWrap = function(){};
}
Shaker.prototype.listen = function(){
// 偵聽搖動
var that = this;
if (this.status == 0 && window.DeviceMotionEvent) {
this.status = 1;
this.handlerWrap = function(event){
that.handler(event)
}
window.addEventListener('devicemotion', this.handlerWrap, false);
}
}
Shaker.prototype.release = function(){
// 停止偵聽
if(this.status == 1){
if (window.DeviceMotionEvent) {
window.removeEventListener('devicemotion', this.handlerWrap);
}
this.status = 0;
this.num = 0;
}
}
Shaker.prototype.reset = function(){
// 重置檢測
if(this.status == 1){
this.num = 0;
}
}
Shaker.prototype.handler = function(event){
// 傳感器事件處理
if(this.status == 1){
var acceleration =event.accelerationIncludingGravity;
var x = acceleration.x;
var y = acceleration.y;
var z = acceleration.z;
if( Math.abs(x-this.lastX) > this.speed ||
Math.abs(y-this.lastY) > this.speed ||
Math.abs(z-this.lastZ) > this.speed )
{
if(this.num == 0){
this.beginSecond = Date.parse(new Date()) / 1000
}
this.num += 1;
}
this.lastX = x;
this.lastY = y;
this.lastZ = z;
if(this.num >= this.minNum){
var now = Date.parse(new Date()) / 1000;
if(now - this.beginSecond <= this.maxSecond){
this.release();
if(this.callback){
this.callback();
}
}
this.reset();
}
}
}
用法:
var s = new Shaker(function(){ /*搖動後的回調*/ });
s.listen();
好了，本文所述給大家介紹到這裡，後續還會持續更新，希望本文給大家分享網頁檢測搖一搖實例代碼的相關知識對大家有所幫助。
