Ajax调用WebPage方法不起作用

Question

我做

<script type="text/javascript"  src="Scripts/jquery-1.4.1.min.js"></script>

<script type="text/javascript">
    function CallPageMethod(methodName, onSuccess, onFail) {
        var args = '';
        var l = arguments.length;
        if (l > 3) {
            for (var i = 3; i < l - 1; i += 2) {
                if (args.length != 0) args += ',';
                args += '"' + arguments[i] + '":"' + arguments[i + 1] + '"';
            }
        }
        var loc = window.location.href;
        loc = (loc.substr(loc.length - 1, 1) == "/") ? loc + "Report.aspx" : loc;
        $.ajax({
            type: "POST",
            url: loc + "/" + methodName,
            data: "{" + args + "}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: onSuccess,
            fail: onFail
        });
    }

    function success(response) {
        alert(response.d);
    }

    function fail(response) {
        alert("&#1054;&#1096;&#1080;&#1073;&#1082;&#1072;.");
    }

    function select() {

        ...........

        CallPageMethod("SelectBook", success, fail, ...........);
    }
</script>

我的脚本管理员是

<asp:ScriptManager ID="ScriptManager1" 
EnableScriptGlobalization="true" 
EnableScriptLocalization="true"
EnablePageMethods="true" 
EnablePartialRendering="true" runat="server" />

但是当我执行select函数时,我什么都没有......根本没有消息.

错误日志:

    [ArgumentException]: Unknown web method SelectBook.
Parameter name: methodName
   at System.Web.Script.Services.WebServiceData.GetMethodData(String methodName)
   at System.Web.Handlers.ScriptModule.OnPostAcquireRequestState(Object sender, EventArgs eventArgs)
   at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

我的网络方法:

<WebMethod()> Public Function SelectBook(ByVal values As String, ByVal valuesG As String, ByVal valuesX As String, ByVal valuesXG As String) As String
    '....
    Return If(((vals.Length = valsG.Length) And (valsX.Length = valsXG.Length)), SQLModule.UpdateAdvCode(vals, valsG, valsX, valsXG), "?????? ?????? ????????????? ?????")
End Function

如果我只做警报(CallPageMethod("SelectBook",成功,失败,...........))我可以看到"未定义",但是什么未定义？我试图调试此JavaScript但无法修复它.它是有效的,我理解它必须如何工作,但我不知道为什么它现在被破坏以及如何解决它.请帮帮我.
