    Hi all,

    Thank you for your time. I am learning how to use Ajax to call a server method and return some value. But, my test code can't return a sting. Below is my code.

    <script src="Scripts/jquery-2.1.3.js"></script>
    <script type="text/javascript">
        $(document).ready(
            function ()
            {
                $.ajax(
                {
                    type: "POST",
                    url: "AjaxCallWebMethod(string).aspx/ReturnString",
                    data: "firstName=Swan&lastName=W",
                    //contentType: "application/json; charset=utf-8",
                    dataType: "text",
                    success: function (data)
                    {
                        $("#Text1").html(data);
                    }
                })
            }
            );
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <input id="Text1" type="text" />
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    </div>
    </form>
    [WebMethod]
        public static string ReturnString(string firstName,string lastName) 
        {
            string Text = "Hello"+firstName+lastName;
            return Text;
        }

    So, kindly provide a solution and provide me a good tutorial about how to use Ajax. Besides call method from server-side, I also want to learn how to call WebAPI, WCF...

    Please help me.
