将毫秒转换为日期(jQuery / JavaScript)

我有点闲逛,但我会尽量保持清楚-

我很无聊,所以我正在研究“ shoutbox”,而我对一件事情有些困惑。我想获取输入消息的时间,并且要确保获取服务器时间,或者至少要确保没有获取用户的本地时间。我知道这没关系,因为除了我之外,任何人都不会使用此东西,但是我想变得更彻底。我环顾四周并测试了几件事,我认为做到这一点的唯一方法是获得自19701月1日00:00:00 UTC以来的毫秒数,因为每个人的时间都是相同的。

我这样做是这样的:

var time = new Date();
var time = time.getTime();

返回一个类似的数字1294862756114

有没有办法将1294862756114日期转换为更具可读性的日期,例如DD/MM/YYYY HH:MM:SS

因此,基本上,我正在寻找与PHPdate();函数等效的JavaScript

    var time = new Date().getTime();
    var date = new Date(time);
    alert(date.toString()); // Wed Jan 12 2011 12:42:46 GMT-0800 (PST)

如果您想为日期设置自定义格式,我可以为其提供一个简单的功能

var now = new Date;
console.log( now.customFormat( "#DD#/#MM#/#YYYY# #hh#:#mm#:#ss#" ) );

以下是支持的令牌:

token:     description:             example:
#YYYY#     4-digit year             1999
#YY#       2-digit year             99
#MMMM#     full month name          February
#MMM#      3-letter month name      Feb
#MM#       2-digit month number     02
#M#        month number             2
#DDDD#     full weekday name        Wednesday
#DDD#      3-letter weekday name    Wed
#DD#       2-digit day number       09
#D#        day number               9
#th#       day ordinal suffix       nd
#hhhh#     2-digit 24-based hour    17
#hhh#      military/24-based hour   17
#hh#       2-digit hour             05
#h#        hour                     5
#mm#       2-digit minute           07
#m#        minute                   7
#ss#       2-digit second           09
#s#        second                   9
#ampm#     "am" or "pm"             pm
#AMPM#     "AM" or "PM"             PM

这是代码:

Date.prototype.customFormat = function(formatString){
  var YYYY,YY,MMMM,MMM,MM,M,DDDD,DDD,DD,D,hhhh,hhh,hh,h,mm,m,ss,s,ampm,AMPM,dMod,th;
  YY = ((YYYY=this.getFullYear())+"").slice(-2);
  MM = (M=this.getMonth()+1)<10?('0'+M):M;
  MMM = (MMMM=["January","February","March","April","May","June","July","August","September","October","November","December"][M-1]).substring(0,3);
  DD = (D=this.getDate())<10?('0'+D):D;
  DDD = (DDDD=["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"][this.getDay()]).substring(0,3);
  th=(D>=10&&D<=20)?'th':((dMod=D%10)==1)?'st':(dMod==2)?'nd':(dMod==3)?'rd':'th';
  formatString = formatString.replace("#YYYY#",YYYY).replace("#YY#",YY).replace("#MMMM#",MMMM).replace("#MMM#",MMM).replace("#MM#",MM).replace("#M#",M).replace("#DDDD#",DDDD).replace("#DDD#",DDD).replace("#DD#",DD).replace("#D#",D).replace("#th#",th);
  h=(hhh=this.getHours());
  if (h==0) h=24;
  if (h>12) h-=12;
  hh = h<10?('0'+h):h;
  hhhh = hhh<10?('0'+hhh):hhh;
  AMPM=(ampm=hhh<12?'am':'pm').toUpperCase();
  mm=(m=this.getMinutes())<10?('0'+m):m;
  ss=(s=this.getSeconds())<10?('0'+s):s;
  return formatString.replace("#hhhh#",hhhh).replace("#hhh#",hhh).replace("#hh#",hh).replace("#h#",h).replace("#mm#",mm).replace("#m#",m).replace("#ss#",ss).replace("#s#",s).replace("#ampm#",ampm).replace("#AMPM#",AMPM);
};

您可以简单地使用Datejs库,以便将日期转换为所需的格式。

我已经进行了几次测试,并且可以正常工作。

以下是说明如何实现该目标的代码段:

var d = new Date(1469433907836);

d.toLocaleString(); // expected output: "7/25/2016, 1:35:07 PM"

d.toLocaleDateString(); // expected output: "7/25/2016"

d.toDateString();  // expected output: "Mon Jul 25 2016"

d.toTimeString(); // expected output: "13:35:07 GMT+0530 (India Standard Time)"

d.toLocaleTimeString(); // expected output: "1:35:07 PM"

下面是一个片段,使您可以将日期格式化为所需的输出:

var time = new Date();
var time = time.getTime();

var theyear = time.getFullYear();
var themonth = time.getMonth() + 1;
var thetoday = time.getDate();

document.write("The date is: ");
document.write(theyear + "/" + themonth + "/" + thetoday);

尝试使用以下代码:

var datetime = 1383066000000; // anything
var date = new Date(datetime);
var options = {
        year: 'numeric', month: 'numeric', day: 'numeric',
    };

var result = date.toLocaleDateString('en', options); // 10/29/2013

尝试使用以下代码:

var milisegundos = parseInt(data.replace("/Date(", "").replace(")/", ""));
var newDate = new Date(milisegundos).toLocaleDateString("en-UE");

好好享受!

试试这个:

var time = new Date().toJSON();

一行代码。

var date = new Date(new Date().getTime());

要么

var date = new Date(1584120305684);
/Date(1383066000000)/

function convertDate(data) {
    var getdate = parseInt(data.replace("/Date(", "").replace(")/", ""));
    var ConvDate= new Date(getdate);
    return ConvDate.getDate() + "/" + ConvDate.getMonth() + "/" + ConvDate.getFullYear();
}

假设日期(以毫秒为单位)是日期1526813885836,因此您可以使用以下示例代码以字符串形式访问日期:

console.log(new Date(1526813885836).toString());

为了清楚起见,请参见以下代码:

const theTime = new Date(1526813885836);
console.log(theTime.toString());

使用datejs

new Date().toString('yyyy-MM-d-h-mm-ss');
