[jQuery] Re: Passing JSON objects to a Web Method

2009-02-28 Thread Mahesh 

Hi Dave,
I'm using .NET 2.0.
And the web method is working fine with static parameters.
I could find a temporary solution of passing the JSON object as a
string and parsing the string into my .NET object using an open source
library Json.NET.
This way it works, but I'd be glad to avoid the 2 additional steps
that I have to carry out.

Regards,
Mahesh Dedhia.

 Mahesh,

 A few things, while I'm remembering:
 1) Are you using .NET 3.5?  The method I gave you will (probably) only work
 with 3.5, although it might work with 3.0.

 2) Make sure you have the following before  the class in your ASMX or ASPX
 file:  [System.Web.Script.Services.ScriptService] (I believe this is new to
 3.5, and is necessary to call your WebService via javascript)

 Does your web method return data if you pass in static data (eg - data:
 {'fname':'John','lname':'Doe'} in your data declaration on the JQuery
 side)?

  Hey Dave,
  Yes, I'm using ASP.NET web method inside an ASPX page.
  I tried your solution, but didn't work.
  Here, the code that I used.

  Default.js
   function Call() {

     var person = { fname : John,
                    lname  : Doe};

     $.ajax({
       type: POST,
       url: Default.aspx/WebMethod,
       //data: {},
       data: person,
        contentType: application/json; charset=utf-8,
        dataType: json,
       success: function(msg) {
         alert('Successful');
       }
     });
   };

  Default.aspx.cs
         [WebMethod]
         public static object WebMethod(string fname, string lname)
         {
             return new { fname = fname, lname = lname };
         }

  Didn't work..
  Apart from that, isn't there a way to recognize the JSON object as
  Object and type-cast it to a similar .NET object?
  I found something here,

  But it is using WCF which I don't want to.

   If you are, I think that you'll find it pretty easy using this:

               $.ajax({
                   type: POST,
                   contentType: application/json; charset=utf-8,
                   url: myWebService.asmx/myWebMethod,
                   data: myJSONObject
                   dataType: json,
                   success: function(json) { // do Stuff }
               });

   Just make sure that myWebMethod takes each item in the JSON object as a
   parameter and everything should work pretty well.

   Good luck!

For example:

and I want to pass this object in the data: {} block.
Is it possible?
