js获取每周固定某一天，某一刻的时间戳_douyiqing的博客

我们以每周  周六和周日  的23:59:59为例

先上代码

// 获取每周指定时间戳
     function getStamp(){
        var _date = new Date(); // 获取当前时间
        var _nowTime = _date.getTime(); // 获取当前时间时间戳
        // 获取当前是周几，0代表是周日
        var _week = _date.getDay() == 0 ? 7 : _date.getDay();
        // 一天时间是多久时间戳
        var _dayLongTime = 24 * 60 * 60 * 1000;

        // 周日
        var _furtureSundayTimes = _nowTime + (7 - _week) * _dayLongTime;
        _furtureSundayTimes = new Date(_furtureSundayTimes);
        var _sunYear = _furtureSundayTimes.getFullYear();
        var _sunMonth = _furtureSundayTimes.getMonth() + 1;
        var _sunDay = _furtureSundayTimes.getDate();
        _sunMonth = _sunMonth >= 10 ? _sunMonth : '0' + _sunMonth;
        _sunDay = _sunDay >= 10 ? _sunDay : '0' + _sunDay;

        // 周六
        var _furtureSaturdayTimes = _nowTime + (6 - _week) * _dayLongTime;
        _furtureSaturdayTimes = new Date(_furtureSaturdayTimes);
        var _satYear = _furtureSaturdayTimes.getFullYear();
        var _satMonth = _furtureSaturdayTimes.getMonth() + 1;
        var _satDay = _furtureSaturdayTimes.getDate();
        _satMonth = _satMonth >= 10 ? _satMonth : '0' + _satMonth;
        _satDay = _satDay >= 10 ? _satDay : '0' + _satDay;

      
        // 这里注意安卓和ios根据指定时间获取时间戳 前者用-连接 后者用/连接
 
        // ios周日 
        var sunEndTime = _sunYear +'/'+_sunMonth+'/'+ _sunDay + ' 23:59:59'
        var sunTimeStamp = new Date(endTime).getTime()
        // 安卓周六
        var satEndTime = _satYear +'-'+_satMonth +'-'+ _satDay + ' 23:59:59'
        var satTimeStamp = new Date(endTime).getTime()

      }// 获取每周指定时间戳
