From another answer on Stackoverflow is a conversion from Javascript date to .net DateTime:
long msSinceEpoch = 1260402952906; // Value from Date.getTime() in JavaScript
return new DateTime(1970, 1, 1) + new TimeSpan(msSinceEpoch * 10000);
But how to do the reverse? DateTime to Javascript Date?
This question is related to
c#
.net
javascript
With Moment.js simply use:
var jsDate = moment(netDateTime).toDate();
Where netDateTime
is your DateTime variable serialized, something like "/Date(1456956000000+0200)/"
.
<input type="hidden" id="CDate" value="<%=DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")%>" />
In order to convert the date to JS date(all numbers):
var JSDate = $("#CDate").val();
JSDate = Date.parse(JSDate);
I know this is a little late, but here's the solution I had to come up with for handling dates when you want to be timezone independent. Essentially it involves converting everything to UTC.
From Javascript to Server:
Send out dates as epoch values with the timezone offset removed.
var d = new Date(2015,0,1) // Jan 1, 2015
// Ajax Request to server ...
$.ajax({
url: '/target',
params: { date: d.getTime() - (d.getTimezoneOffset() * 60 * 1000) }
});
The server then recieves 1420070400000 as the date epoch.
On the Server side, convert that epoch value to a datetime object:
DateTime d = new DateTime(1970, 1, 1, 0, 0, 0).AddMilliseconds(epoch);
At this point the date is just the date/time provided by the user as they provided it. Effectively it is UTC.
Going the other way:
When the server pulls data from the database, presumably in UTC, get the difference as an epoch (making sure that both date objects are either local or UTC):
long ms = (long)utcDate.Subtract(new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalMilliseconds;
or
long ms = (long)localDate.Subtract(new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Local)).TotalMilliseconds;
When javascript receives this value, create a new date object. However, this date object is going to be assumed local time, so you need to offset it by the current timezone:
var epochValue = 1420070400000 // value pulled from server.
var utcDateVal = new Date(epochValue);
var actualDate = new Date(utcDateVal.getTime() + (utcDateVal.getTimezoneOffset() * 60 * 1000))
console.log(utcDateVal); // Wed Dec 31 2014 19:00:00 GMT-0500 (Eastern Standard Time)
console.log(actualDate); // Thu Jan 01 2015 00:00:00 GMT-0500 (Eastern Standard Time)
As far as I know, this should work for any time zone where you need to display dates that are timezone independent.
If you use MVC with razor
-----Razor/C#
var dt1 = DateTime.Now.AddDays(14).Date;
var dt2 = DateTime.Now.AddDays(18).Date;
var lstDateTime = new List<DateTime>();
lstDateTime.Add(dt1);
lstDateTime.Add(dt2);
---Javascript
$(function() {
var arr = []; //javascript array
@foreach (var item in lstDateTime)
{
@:arr1.push(new Date(@item.Year, @(item.Month - 1), @item.Day));
}
Good luck
This method is working for me:
public sCdateToJsDate(cSDate: any): Date {
// cSDate is '2017-01-24T14:14:55.807'
var datestr = cSDate.toString();
var dateAr = datestr.split('-');
var year = parseInt(dateAr[0]);
var month = parseInt(dateAr[1])-1;
var day = parseInt(dateAr[2].substring(0, dateAr[2].indexOf("T")));
var timestring = dateAr[2].substring(dateAr[2].indexOf("T") + 1);
var timeAr = timestring.split(":");
var hour = parseInt(timeAr[0]);
var min = parseInt(timeAr[1]);
var sek = parseInt(timeAr[2]);
var date = new Date(year, month, day, hour, min, sek, 0);
return date;
}
JavaScript Date constructor accepts number of milliseconds since Unix epoch (1 January 1970 00:00:00 UTC). Here’s C# extension method that converts .Net DateTime object to JavaScript date:
public static class DateTimeJavaScript
{
private static readonly long DatetimeMinTimeTicks =
(new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).Ticks;
public static long ToJavaScriptMilliseconds(this DateTime dt)
{
return (long)((dt.ToUniversalTime().Ticks - DatetimeMinTimeTicks) / 10000);
}
}
JavaScript Usage:
var dt = new Date(<%= DateTime.Today.ToJavaScriptMilliseconds() %>);
alert(dt);
Another late answer, but this is missing here. If you want to handle conversion of serialized /Date(1425408717000)/
in javascript, you can simply call:
var cSharpDate = "/Date(1425408717000)/"
var jsDate = new Date(parseInt(cSharpDate.replace(/[^0-9 +]/g, '')));

You can try this in your Action:
return DateTime.Now.ToString("yyyy-MM-ddTHH:mm:ss");
And this in your Ajax success:
success: function (resultDateString) {
var date = new Date(resultDateString);
}
Or this in your View: (Javascript plus C#)
var date = new Date('@DateTime.Now.ToString("yyyy-MM-ddTHH:mm:ss")');
This should do the trick:
date.Subtract(new DateTime(1970, 1,1)).TotalMilliseconds
