Getting error 500 while using Ajax call in ASP.NET Webforms

Question

I am trying to call a simple void in html page but it shows error 500. Can anyone help me i'm getting crazy! In console log shows this error :

POST http://localhost:15041/Default.aspx/SaveUser 500 (Internal Server Error)

my html code :

<head runat="server">
    <title></title>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

</head>
<body>
    <form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="True"></asp:ScriptManager>


    </form>
    <script>
        $.ajax({
            type: "POST",
            url: "/Default.aspx/SaveUser",
            data: "{id:'1'}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (msg) {
                alert("SUCCESS: " + msg.d);
            },
            error: function (err) {
                alert("FAILURE");
            }
        });
</script>
</body>

and here is my C# code :

[WebMethod]
        [ScriptMethod]
        public static int SaveUser(int param)
        {
            return 10;
        }

正如@Zaki所说，这是我的错误，我应该将ajax的data部分更改为：data：“ {param：'1'}”
