Pass a datetime from javascript to c# (Controller)

问题:

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.

回答1:

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                        
    }
});

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());
}

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();

回答4:

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

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);
            }
        });

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");
