Jquery's Ajax Property For Asp.Net 2.0

Question

I always see the code like this in the blogs:

$.ajax({
                    type: "POST",
                    contentType: "application/json; charset=utf-8",
                    url: "WebService.asmx/HelloWorld",
                    data: "{}",
                    dataType: "json",
                    success: function(msg) {
                        alert(msg.d);
                    }
                });

But I think this is run only with asp.net 3.5. I couldn't run it with 2.0. How can I use such these codes in my Applications?

Answer 1

You need to add this attribute to your webserver class

[System.Web.Script.Services.ScriptService]
public class Service : System.Web.Services.WebService

and this attribute to your functions

[ScriptMethod(ResponseFormat = ResponseFormat.Json)]

You don't technically need to specify the responseformat, as it responds according to the format you specify in the request. And you must specify a format in the request.
