How to get date time in JavaScript with format 31/12/2010 03:55 AM?
Javascript Solutions
Solution 1 - Javascript
Semantically, you're probably looking for the one-liner
new Date().toLocaleString()
which formats the date in the locale of the user.
If you're really looking for a specific way to format dates, I recommend the moment.js library.
Solution 2 - Javascript
If the format is "fixed" meaning you don't have to use other format you can have pure JavaScript instead of using whole library to format the date:
//Pad given value to the left with "0"
function AddZero(num) {
return (num >= 0 && num < 10) ? "0" + num : num + "";
}
window.onload = function() {
var now = new Date();
var strDateTime = [[AddZero(now.getDate()),
AddZero(now.getMonth() + 1),
now.getFullYear()].join("/"),
[AddZero(now.getHours()),
AddZero(now.getMinutes())].join(":"),
now.getHours() >= 12 ? "PM" : "AM"].join(" ");
document.getElementById("Console").innerHTML = "Now: " + strDateTime;
};
<div id="Console"></div>
The variable strDateTime will hold the date/time in the format you desire and you should be able to tweak it pretty easily if you need.
I'm using join as good practice, nothing more, it's better than adding strings together.
Solution 3 - Javascript
var now = new Date();
now.format("dd/MM/yyyy hh:mm TT");

Solution 4 - Javascript
Date().toLocaleString() returns this: 7/31/2018, 12:58:03 PM
Pretty close - just drop the comma and the seconds:
new Date().toLocaleString().replace(",","").replace(/:.. /," ");
Results: 7/31/2018 12:58 PM
Solution 5 - Javascript
try this:
var today = new Date();
var date = today.getFullYear()+'-'+(today.getMonth()+1)+'-'+today.getDate();
var time = today.getHours()+':'+today.getMinutes()+':'+today.getSeconds();
console.log(date + ' '+ time);
Solution 6 - Javascript
function pad_2(number)
{
return (number < 10 ? '0' : '') + number;
}
function hours(date)
{
var hours = date.getHours();
if(hours > 12)
return hours - 12; // Substract 12 hours when 13:00 and more
return hours;
}
function am_pm(date)
{
if(date.getHours()==0 && date.getMinutes()==0 && date.getSeconds()==0)
return ''; // No AM for MidNight
if(date.getHours()==12 && date.getMinutes()==0 && date.getSeconds()==0)
return ''; // No PM for Noon
if(date.getHours()<12)
return ' AM';
return ' PM';
}
function date_format(date)
{
return pad_2(date.getDate()) + '/' +
pad_2(date.getMonth()+1) + '/' +
(date.getFullYear() + ' ').substring(2) +
pad_2(hours(date)) + ':' +
pad_2(date.getMinutes()) +
am_pm(date);
}

Solution 7 - Javascript
You can convert Date to almost any format using the Snippet I have added below.
Code:
dateFormat(new Date(),"dd/mm/yy h:MM TT")
//"20/06/14 6:49 PM"
Other examples
// Can also be used as a standalone function
dateFormat(new Date(), "dddd, mmmm dS, yyyy, h:MM:ss TT");
// Saturday, June 9th, 2007, 5:46:21 PM
dateFormat(new Date(),"dddd d mmmm yyyy")
//Monday 2 June 2014"
Snippet:
Add following code taken from this link into your code.
var dateFormat = function () {
var token = /d{1,4}|m{1,4}|yy(?:yy)?|([HhMsTt])\1?|[LloSZ]|"[^"]*"|'[^']*'/g,
timezone = /\b(?:[PMCEA][SDP]T|(?:Pacific|Mountain|Central|Eastern|Atlantic) (?:Standard|Daylight|Prevailing) Time|(?:GMT|UTC)(?:[-+]\d{4})?)\b/g,
timezoneClip = /[^-+\dA-Z]/g,
pad = function (val, len) {
val = String(val);
len = len || 2;
while (val.length < len) val = "0" + val;
return val;
};
// Regexes and supporting functions are cached through closure
return function (date, mask, utc) {
var dF = dateFormat;
// You can't provide utc if you skip other args (use the "UTC:" mask prefix)
if (arguments.length == 1 && Object.prototype.toString.call(date) == "[object String]" && !/\d/.test(date)) {
mask = date;
date = undefined;
}
// Passing date through Date applies Date.parse, if necessary
date = date ? new Date(date) : new Date;
if (isNaN(date)) throw SyntaxError("invalid date");
mask = String(dF.masks[mask] || mask || dF.masks["default"]);
// Allow setting the utc argument via the mask
if (mask.slice(0, 4) == "UTC:") {
mask = mask.slice(4);
utc = true;
}
var _ = utc ? "getUTC" : "get",
d = date[_ + "Date"](),
D = date[_ + "Day"](),
m = date[_ + "Month"](),
y = date[_ + "FullYear"](),
H = date[_ + "Hours"](),
M = date[_ + "Minutes"](),
s = date[_ + "Seconds"](),
L = date[_ + "Milliseconds"](),
o = utc ? 0 : date.getTimezoneOffset(),
flags = {
d: d,
dd: pad(d),
ddd: dF.i18n.dayNames[D],
dddd: dF.i18n.dayNames[D + 7],
m: m + 1,
mm: pad(m + 1),
mmm: dF.i18n.monthNames[m],
mmmm: dF.i18n.monthNames[m + 12],
yy: String(y).slice(2),
yyyy: y,
h: H % 12 || 12,
hh: pad(H % 12 || 12),
H: H,
HH: pad(H),
M: M,
MM: pad(M),
s: s,
ss: pad(s),
l: pad(L, 3),
L: pad(L > 99 ? Math.round(L / 10) : L),
t: H < 12 ? "a" : "p",
tt: H < 12 ? "am" : "pm",
T: H < 12 ? "A" : "P",
TT: H < 12 ? "AM" : "PM",
Z: utc ? "UTC" : (String(date).match(timezone) || [""]).pop().replace(timezoneClip, ""),
o: (o > 0 ? "-" : "+") + pad(Math.floor(Math.abs(o) / 60) * 100 + Math.abs(o) % 60, 4),
S: ["th", "st", "nd", "rd"][d % 10 > 3 ? 0 : (d % 100 - d % 10 != 10) * d % 10]
};
return mask.replace(token, function ($0) {
return $0 in flags ? flags[$0] : $0.slice(1, $0.length - 1);
});
};
}();
// Some common format strings
dateFormat.masks = {
"default": "ddd mmm dd yyyy HH:MM:ss",
shortDate: "m/d/yy",
mediumDate: "mmm d, yyyy",
longDate: "mmmm d, yyyy",
fullDate: "dddd, mmmm d, yyyy",
shortTime: "h:MM TT",
mediumTime: "h:MM:ss TT",
longTime: "h:MM:ss TT Z",
isoDate: "yyyy-mm-dd",
isoTime: "HH:MM:ss",
isoDateTime: "yyyy-mm-dd'T'HH:MM:ss",
isoUtcDateTime: "UTC:yyyy-mm-dd'T'HH:MM:ss'Z'"
};
// Internationalization strings
dateFormat.i18n = {
dayNames: [
"Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat",
"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"
],
monthNames: [
"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec",
"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"
]
};
// For convenience...
Date.prototype.format = function (mask, utc) {
return dateFormat(this, mask, utc);
};

I realize this question was asked almost a decade ago and answered several times over. But given I still stumbled here with the same question, I have found some encouraging solutions that I figured I'd share:
(new Date()).toJSON(); // "2021-08-16T16:31:53.596Z"
(new Date()).toLocaleString(); // "8/16/2021, 11:40:57 AM"
(new Date()).toLocaleDateString(); // "8/16/2021"
(new Date()).toLocaleTimeString(); // "11:37:13 AM"

@Shadow Wizard's code should return 02:45 PM instead of 14:45 PM. So I modified his code a bit:
function getNowDateTimeStr(){
var now = new Date();
var hour = now.getHours() - (now.getHours() >= 12 ? 12 : 0);
return [[AddZero(now.getDate()), AddZero(now.getMonth() + 1), now.getFullYear()].join("/"), [AddZero(hour), AddZero(now.getMinutes())].join(":"), now.getHours() >= 12 ? "PM" : "AM"].join(" ");
}
//Pad given value to the left with "0"
function AddZero(num) {
return (num >= 0 && num < 10) ? "0" + num : num + "";
}
