Time Processing, space dynamics 1 minute ago, yesterday, 2 days ago

Provides various official and user-released code examples. For code reference, you are welcome to exchange and learn the time processing class library. You can pass in the timestamp. One time written by myself, such as one minute before mobile phone communication, two hours ago, yesterday, three days ago, January 1, April 5

Timestamp can be input

Key code:
Var NOW = new Date (); // obtain the current system time
Date. prototype. format = function (format ){
Var o = {
"M +": this. getMonth () + 1, // month
"D +": this. getDate (), // day
"H +": this. getHours (), // hour
"M +": this. getMinutes (), // minute
"S +": this. getSeconds (), // second
"Q +": Math. floor (this. getMonth () + 3)/3), // quarter
"S": this. getMilliseconds () // millisecond
}

If (/(y +)/. test (format )){
Format = format. replace (RegExp. $1, (this. getFullYear () + ""). substr (4-RegExp. $1. length ));
}

For (var k in o ){
