I'm using the following code to pass to my javascript code
sb.Append("start: new Date(" + Convert.ToDateTime(appointment.AppointmentDate).Subtract(new DateTime(1970, 1, 1)).TotalMilliseconds.ToString() + "),");
The problem is that it's not including the time along with the date. How can I include the time as well?
Thanks!
You can parse date/time string which is in en-US format.
Put this code in your aspx page into the SCRIPT tag and you will have your DateTime value in dt variable.
var dtString = '<%= MyDateTimeObject.ToString((new System.Globalization.CultureInfo("en-US")).DateTimeFormat) %>';
var dt = new Date(dtString );
The problem is probably regional settings, try:
sb.Append("start: new Date(" + Convert.ToDateTime(appointment.AppointmentDate).Subtract(new DateTime(1970, 1, 1)).TotalMilliseconds.ToString(System.Globalization.CultureInfo.InvariantCulture.NumberFormat) + "),");
new Date(<number you got>) The number is the milliseconds. The above should work by the way, try pasting this in your url bar: javascript:alert(new Date(1288260000000) )
If you have .NET 3.5+ or the AJAX Extensions for .NET 2.0, you may already have the methods you need to convert objects to JavaScript in the JavaScriptSerializer class.
Add a reference to System.Web.Extensions.
using System.Web.Script.Serialization;
...
var jsSerializer = new JavaScriptSerializer();
string jsDate = jsSerializer.Serialize(appointment.AppointmentDate);
Now, on the JS side, you're going to have to undo the JSON serialization using a JSON parser.
One way is to use Date.parse that can handle many more formats.
var d = new Date(Date.parse("<your date here>"));
You need to use new Date and Date.parse because Date.parse does not return a date object but number of milliseconds since 1970 nnn something.
using System;
class Program
{
static void Main(string[] args)
{
DateTime? myTime = new DateTime(1970, 1, 1, 0, 0, 1);
Console.Write(myTime.Value.ToUnixTimeInMs().ToString());
Console.Read();
}
}
public static class DateTimeExtensions
{
private static readonly DateTime unixEpoch = new DateTime(1970, 1, 1);
public static double ToUnixTimeInMs(this DateTime dateTime)
{
return dateTime.Subtract(DateTimeExtensions.unixEpoch).TotalMilliseconds;
}
}
Simply pass the return value of ToUnixTimeInMs() into the constructor of a JavaScript Date object.
