废话不多说了，直接给大家贴代码了，具体代码如下所示：
var Shaker = function(f){ // 摇一摇: 检测到3次摇动算一次摇一摇, 摇动后调用处理函数, 不再检测摇动 // f 摇动后的回调 this.callback = f; this.status = 0; // 0: 侦听未开始 1: 侦听开始 this.speed = 15; this.lastX = this.lastY = this.lastZ = 0; this.num = 0; // 检测触发次数 this.minNum = 3; // 最小检测触发次数 this.beginSecond = 0; // 开始检测的秒数 this.maxSecond = 3; // 最大间隔秒数 this.handlerWrap = function(){}; } Shaker.prototype.listen = function(){ // 侦听摇动 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(){ // 停止侦听 if(this.status == 1){ if (window.DeviceMotionEvent) { window.removeEventListener('devicemotion', this.handlerWrap); } this.status = 0; this.num = 0; } } Shaker.prototype.reset = function(){ // 重置检测 if(this.status == 1){ this.num = 0; } } Shaker.prototype.handler = function(event){ // 传感器事件处理 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(){ /*摇动后的回调*/ }); s.listen();
