Date and JSON.stringify()

Question

5.00/5 (1 vote)

I have written a code to stringify an object in JSON format using jquery.

JavaScript

var o = new Object();
o.Price = "56";
o.Reason = "Tea";
var followupDate = "17-12-2013";
o.Date = new Date(followupDate);
var str = JSON.stringify(o);

Here the 'str' is the string in which i get a json.

C#

{"Price":"56","Reason":"Tea","Date":"2013-12-17T06:33:18.058Z"}

when i pass this string to my wcf method, i get an error

There was an error deserializing the object of type WcfService1.ExpenseClass. DateTime content '2013-12-17T06:33:18.058Z' does not start with '/Date(' and end with ')/' as required for JSON.

Here is the code which i used to cast json string to a class

C#

ExpenseClass exp = new ExpenseClass();
using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(str)))
{
  DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(ExpenseClass));
  exp = serializer.ReadObject(ms) as ExpenseClass; //Error encounters here
}

what shall i do?

Alsalaam Aleykum.

All you have to do is to respond to the error. I mean change the date format so the json can parse it to the web service.

your code should look like this:

JavaScript

var o = new Object();
o.Price = "56";
o.Reason = "Tea";
var followupDate = "17-12-2013";
o.Date = new Date(followupDate);
o.Date = "\/Date("+o.Date.valueOf()+")\/";          
// valueOf() method Returns the primitive value of a Date object.

First of all this is a very much old question, you should not post answers on old threads just to gain reputation.

Then, why are you setting the value to Date member of o object twice?


o.Date = new Date(followupDate);
o.Date = "\/Date("+o.Date.valueOf()+")\/";

I just faced this problem recently, and I wanted to share my solution. Anyway, do you have a problem when other members want to gain a reputation. I'm a fresh member and the code project does not recommend members not to add solutions to old threads. Does it?

BTW, I made it like that just to make it easy to other people and not to use extra variable:

var date = new Date(followupDate);
o.Date = "\/Date("+date.valueOf()+")\/";

Is that what you want?
