Pass a datetime from javascript to c# (Controller)
C#JqueryJsonasp.net Mvc-3C# Problem Overview
How do you pass a date time (i need it to the second) to c# using jquery and mvc3. This is what I have
var date = new Date();
$.ajax(
{
type: "POST",
url: "/Group/Refresh",
contentType: "application/json; charset=utf-8",
data: "{ 'MyDate': " + date.toUTCString() + " }",
success: function (result) {
//do something
},
error: function (req, status, error) {
//error
}
});
I can't figure out what format the date should be in, for C# to understand it.
C# Solutions
Solution 1 - C#
Try to use toISOString(). It returns string in ISO8601 format.
GET method
javascript
$.get('/example/doGet?date=' + new Date().toISOString(), function (result) {
console.log(result);
});
c#
[HttpGet]
public JsonResult DoGet(DateTime date)
{
return Json(date.ToString(), JsonRequestBehavior.AllowGet);
}
POST method
javascript
$.post('/example/do', { date: date.toISOString() }, function (result) {
console.log(result);
});
c#
[HttpPost]
public JsonResult Do(DateTime date)
{
return Json(date.ToString());
}
Solution 2 - C#
The following format should work:
$.ajax({
type: "POST",
url: "@Url.Action("refresh", "group")",
contentType: "application/json; charset=utf-8",
data: JSON.stringify({
myDate: '2011-04-02 17:15:45'
}),
success: function (result) {
//do something
},
error: function (req, status, error) {
//error
}
});
Solution 3 - C#
There is a toJSON()
method in javascript returns a string representation of the Date object. toJSON() is IE8+ and toISOString() is IE9+. Both results in YYYY-MM-DDTHH:mm:ss.sssZ
format.
var date = new Date();
$.ajax(
{
type: "POST",
url: "/Group/Refresh",
contentType: "application/json; charset=utf-8",
data: "{ 'MyDate': " + date.toJSON() + " }",
success: function (result) {
//do something
},
error: function (req, status, error) {
//error
}
});
Solution 4 - C#
try this
var date = new Date();
$.ajax(
{
type: "POST",
url: "/Group/Refresh",
contentType: "application/json; charset=utf-8",
data: "{ 'MyDate': " + date.getTimezoneOffset() + " }",
success: function (result) {
//do something
},
error: function (req, status, error) {
//error
}
});
In C#
DateTime.Now.ToUniversalTime().AddMinutes(double.Parse(MyDate)).ToString();
Solution 5 - C#
Update: Please see marked answer as a better solution to implement this. The following solution is no longer required.
Converting the json date to this format "mm/dd/yyyy HH:MM:ss"
dateFormat is a jasondate format.js file found at blog.stevenlevithan.com
var _meetStartTime = dateFormat(now, "mm/dd/yyyy HH:MM:ss");
Solution 6 - C#
I found that I needed to wrap my datetime string like this:
"startdate": "\/Date(" + date() + ")\/"
Took me an hour to figure out how to enable the WCF service to give me back the error message which told me that XD
Solution 7 - C#
var Ihours = Math.floor(TotMin / 60);
var Iminutes = TotMin % 60; var TotalTime = Ihours+":"+Iminutes+':00';
$.ajax({
url: ../..,
cache: false,
type: "POST",
data: JSON.stringify({objRoot: TotalTime}) ,
dataType: 'json',
contentType: "application/json; charset=utf-8",
success: function (response) {
},
error: function (er) {
console.log(er);
}
});
