本文实例为大家分享了js实现网页同时进行多个倒计时的具体代码,供大家参考,具体内容如下
创建一个时间类Timer.
每个商品的倒计时生成一个实例:var time = new Timer();
/** *startime 应该是毫秒数 */ var Alarm = function (startime, endtime, countFunc, endFunc) { this.time = Math.floor((endtime - startime) / 1000); //时间 this.countFunc = countFunc; //计时函数 this.endFunc = endFunc; //结束函数 this.flag = 't' + Date.parse(new Date()); // }; Alarm.prototype.start = function () { var self = this; self.flag = setInterval(function () { if (self.time < 0) { clearInterval(self.flag); self.endFunc(); console.log('计时结束'); } else { var minute, hour, day, second; day = Math.floor(self.time / 60 / 60 / 24) < 10 ? '0' + Math.floor(self.time / 60 / 60 / 24) : Math.floor(self.time / 60 / 60 / 24); hour = Math.floor(self.time / 60 / 60 % 24) < 10 ? '0' + Math.floor(self.time / 60 / 60 % 24) : Math.floor(self.time / 60 / 60 % 24); minute = Math.floor(self.time / 60 % 60) < 10 ? '0' + Math.floor(self.time / 60 % 60) : Math.floor(self.time / 60 % 60); second = Math.floor(self.time % 60) < 10 ? '0' + Math.floor(self.time % 60) : Math.floor(self.time % 60); //倒计时执行函数 self.countFunc(second, minute, hour, day); self.time--; } }, 1000); }
如果调用:
var time1 = new Alarm(startime, endtime, countFunc, endFunc); time1.start(); var time2 = new Alarm(startime, endtime, countFunc, endFunc); time2.start(); ...
调用示例:
var countTime = function () { var eles = $('.count_time'), len = eles.length; for (; len > 0; len--) { var ele = eles.eq(len - 1); (function (ele) { startTime = new Date(ele.attr('data-start-time')).getTime(), endTime = new Date(ele.attr('data-end-time')).getTime(), alarm = new Alarm(startTime, endTime, function (second, minute, hour, day) { //计时钟 ele.text(hour + ':' + minute + ':' + second); }, function () { //倒计时结束 ele.text('00:00:00'); window.location.reload(); }); alarm.start(); })(ele); } }; countTime();
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持三水点靠木。
