//dateTimeStamp是一个时间毫秒，注意时间戳是秒的形式，在这个毫秒的基础上除以1000，就是十位数的时间戳。13位数的都是时间毫秒。
 
  function timeago(dateTimeStamp){   
        var minute = 1000 * 60;      //把分，时，天，周，半个月，一个月用毫秒表示
        var hour = minute * 60;
        var day = hour * 24;
        var week = day * 7;
        var halfamonth = day * 15;
        var month = day * 30;
        var now = new Date().getTime();   //获取当前时间毫秒
        console.log(now)
        var diffValue = now - dateTimeStamp;//时间差
    
        if(diffValue < 0){ 
            return;
        }
        var minC = diffValue/minute;  //计算时间差的分，时，天，周，月
        var hourC = diffValue/hour;
        var dayC = diffValue/day;
        var weekC = diffValue/week;
        var monthC = diffValue/month;
        if(monthC >= 1 && monthC <= 3){ 
            result = " " + parseInt(monthC) + "月前"
        }else if(weekC >= 1 && weekC <= 3){ 
            result = " " + parseInt(weekC) + "周前"
        }else if(dayC >= 1 && dayC <= 6){ 
            result = " " + parseInt(dayC) + "天前"
        }else if(hourC >= 1 && hourC <= 23){ 
            result = " " + parseInt(hourC) + "小时前"
        }else if(minC >= 1 && minC <= 59){ 
            result =" " + parseInt(minC) + "分钟前"
        }else if(diffValue >= 0 && diffValue <= minute){ 
            result = "刚刚"
        }else { 
            var datetime = new Date();
            datetime.setTime(dateTimeStamp);
            var Nyear = datetime.getFullYear();
            var Nmonth = datetime.getMonth() + 1 < 10 ? "0" + (datetime.getMonth() + 1) : datetime.getMonth() + 1;
            var Ndate = datetime.getDate() < 10 ? "0" + datetime.getDate() : datetime.getDate();
            var Nhour = datetime.getHours() < 10 ? "0" + datetime.getHours() : datetime.getHours();
            var Nminute = datetime.getMinutes() < 10 ? "0" + datetime.getMinutes() : datetime.getMinutes();
            var Nsecond = datetime.getSeconds() < 10 ? "0" + datetime.getSeconds() : datetime.getSeconds();
            result = Nyear + "-" + Nmonth + "-" + Ndate
