Question

Do I have to do anything special to my controller action method to accept/bind data from a .ajax() call?

Controller Action –

public class TestController : Controller {     public JsonResult GetTestJsonData(Metadata data)     {         return new JsonResult { Data = data };     } } 

JQuery Call –

<script type='text/javascript'>     $(document).ready(function() {         $.ajax({             type: 'POST',             url: 'GetTestJsonData',             data: '{ data: {Name:'joe'}}',             contentType: 'application/json; charset=utf-8',             dataType: 'json',             success: function(msg) {                 alert('Name = ' + msg.Name);             }         });     }); </script> 

I would expect that this page would alert with the name ‘joe’. I’m passing json data from the client to the controller action and the action passes it back to the client. This is just a simple example of what I’m trying to do.

Your code will probably work for a simple example as you are not parsing anything, however if you wanted to translate your JSON to a real object on the controller action then you will need to tell MVC how to go about it.

There is a blog post on writing a JsonFilterAttribute which uses Json.NET to de-serialize the incoming JSON and translate it into an object.
