Front End (js/jquery) conversion of date and time stamps

Get the timestamp of the current time in JavaScript

Method One:

var timestamp=date.parse (new Date ());   = = = = 1451441086000 Result (s):

　　Note : This method is accurate to the second, and the millisecond position is replaced with 0.

Method Two:

var timestamp= (new Date ()). ValueOf ();  = = = = 1451441232779 Result (s):

Note: Both methods get the number of milliseconds that start at midnight on January 1, 1970

Method Three:

　　Using the new Date (). GetTime () method in JavaScript , use theDate.now () method directly with IE8 or later

IE8 or later
if (! Date.now) {
Date.now = function () {return new Date (). GetTime ();};
}
JQuery gets timestamp $.now () var timestamp = $.now ();

Ii. jquery converts specific time into timestamps

1. Introduction of Jquery.extend.date.js plug-in

<script type= "Text/javascript" src= ". /js/jquery.extend.date.js "></script>

2. Code principle

(function ($) {$.extend ({myTime: {/** * current timestamp * @return <int>            Unix timestamp (seconds) */curtime:function () {return date.parse (new Date ())/1000; },/** * Date converted to UNIX timestamp * @param <string> 2014-01-01 20:20:20 Date grid Type * @return <int> Unix Timestamp (SEC) */Datetounix:fu                Nction (String) {var f = string.split (', 2);                var d = (f[0]? F[0]: '). Split ('-', 3);                var t = (f[1]? F[1]: '). Split (': ', 3);                         Return (New Date (parseint (d[0), ten) | | null, (parseint (d[1], 10) | | 1)-1, parseint (D[2], 10) | | NULL, parseint (t[0], 10) | | NULL, parseint (t[1], 10) | | NULL, parseint (t[2], 10) | | Null)). GetTime ()/1000;                           },/** * Timestamp conversion date * @param <int> unixtime Time stamp (sec) * @param <bool> Isfull return full time (y-m-d or y-m-d h:i:s) * @param &                lt;int> TimeZone Time Zone */unixtodate:function (unixtime, Isfull, TimeZone) { if (typeof (timeZone) = = ' number ') {unixtime = parseint (unixtime) + parseint (                TimeZone) * 60 * 60;                } var time = new Date (unixtime * 1000);                var ymdhis = "";                Ymdhis + = Time.getutcfullyear () + "-";                Ymdhis + = (time.getutcmonth () +1) + "-";                Ymdhis + = Time.getutcdate ();                    if (Isfull = = = True) {Ymdhis + = "" + time.getutchours () + ":";       Ymdhis + = time.getutcminutes () + ":";             Ymdhis + = Time.getutcseconds ();            } return ymdhis; }        }    });}) (JQuery);

3. Application

$.mytime. Datetounix (' 2015-12-30 12:30:15 '); The date is converted to timestamp $.mytime. Unixtodate (1451442143254);  Time Stamp converted to date
