Javascript serialization of DateTime in asp.net is not giving a javascript date object?

rated 0 times [ 14] [ 1] / answers: 1 / hits: 45436 / 15 Years ago, mon, august 3, 2009, 12:00:00

When I parse a DateTime to json in .Net it returns a string (i.e. /Date(1249335194272)/). How do I make it return a js Date object constructor not wrap in a string?

// js server code

var dteNow = <%= jsonDateNow %>;





// js rendered code

var dteNow = /Date(1249335477787)/;





// C#

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.Script.Serialization;

using System.Web.UI.WebControls;



namespace testing{

    public partial class iTaxPrep : System.Web.UI.Page

    {

        protected string jsonDateNow;

        protected void Page_Load(object sender, EventArgs e)

        {

            if (!IsPostBack)

            {

                jsonDateNow = new JavaScriptSerializer().Serialize(DateTime.Now);



            }

        }

    }

}

This seems to work (Thanks Chris S for the idea). In the C# do a replace to remove the string wrapper from around the date object;

    using System.Collections.Generic;

        using System.Linq;

        using System.Web;

        using System.Web.UI;

        using System.Web.Script.Serialization;

        using System.Web.Script.Services;

        using System.Web.Services;

        using System.Web.UI.WebControls;



        namespace test

        {

            [ScriptService]

            public partial class testing: System.Web.UI.Page

            {

                protected string strCaseID;

                protected string jsonCase;



                protected void Page_Load(object sender, EventArgs e)

                {

                    if (!IsPostBack)

                    {

                        strCaseID =Tools.GetQueryObject(id);

                        // get a complex object with dates, string, arrays etc.

                        jsonESHACase = new JavaScriptSerializer().Serialize(objCase.Get(strCaseID ))

                            .Replace(\/Date(, new Date().Replace()\/, ));

                    }

                }

            }

        }

..and after removing the quotes and adding the new prefix to Date this js now works. Hooray!

testCase= <%= jsonESHACase %>;

    if (testCase) {

        document.write(testCase[ClosingDate].format(MM dd yyyy));

    }
