Question

I\'m trying to pass JSON from jQuery to a .ASHX file. Example of the jQuery below:

      type: \"POST\",
      url: \"/test.ashx\",
      data: \"{\         


        

Answer 1

The following solution worked for me:

Client Side:

        $.ajax({
            type: "POST",
            url: "handler.ashx",
            data: { firstName: 'stack', lastName: 'overflow' },
            // DO NOT SET CONTENT TYPE to json
            // contentType: "application/json; charset=utf-8", 
            // DataType needs to stay, otherwise the response object
            // will be treated as a single string
            dataType: "json",
            success: function (response) {
                alert(response.d);
            }
        });

Server Side .ashx

    using System;
    using System.Web;
    using Newtonsoft.Json;

    public class Handler : IHttpHandler
    {
        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";

            string myName = context.Request.Form["firstName"];

            // simulate Microsoft XSS protection
            var wrapper = new { d = myName };
            context.Response.Write(JsonConvert.SerializeObject(wrapper));
        }

        public bool IsReusable
        {
           get
           {
                return false;
           }
        }
    }
