ASP.NET ajax do not work

Question

I do not know why this do not work(can not call SendValues method).There is no error raise up. Can anyone help me ? Thank you very much!

The html page some thing like below:

 <script language="javascript" type="text/javascript">
     $(function () {
         $("#Button1").click(function () {
             $.ajax({
                 type: "POST",
                 url: "WebForm1.aspx/SendValues",
                 data: { 'Code': '1026' },
                 contentType: "application/json; charset=utf-8",
                 dataType: "json",
                 success: function (json) {
                     alert(json.d);
                 },
                 failure: function () {
                     alert("Sorry,there is a error!");
                 }
             });

         });
     });
 </script>

The c# code Some thing like:

 public partial class WebForm1 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    [WebMethod]
    public static string SendValues(string Code)
    {
        string contects = string.Empty;

        return contects;
    }

}

Answer 1

我已经通过将数据{{'Code'：'1026'}修改为“ data：{'Code'：'1026'}”解决了这个问题

Answer 2

数据应指定为

data: '{ Code:["1026"]}'
