//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
}
return result;
}
