Answer 1

Create a method in your class:

public partial class Default2 : System.Web.UI.Page
{
   protected void Page_Load(object sender, EventArgs e)
   {

   }

  [WebMethod]
   public static string TestingAjax(string name,string city)
   {
    return name;
   }

}

and call it using jquery ajax like this:

 $(document).ready(function () {

    var JsonData = JSON.stringify({ 
       name: "Donald Duck",
       city: "Duckburg"
});    
         $.ajax({
        type: "POST",
        contentType: "application/json; charset=utf-8",
        url: "Default.aspx/TestingAjax",
        data:  JsonData ,
        dataType: "json",

        success: function(data) {

        console.log(data);

        },
        error: function(result) {
        alert("Error");
        }
        });
    });
