Javascript serialization of DateTime in asp.net is not giving a javascript date object?
This is a known limitation with JSON. This answer might help you, specifically:
value = new Date(parseInt(value.replace("/Date(", "").replace(")/",""), 10));
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"));
}
Simple javascript manipulation like this:
function(param){
var date = new Date(parseInt(param.substr(6)));
return date;
}
Pass in JSON date as param to the function and it will return a javascript date.
