Question

您好我的网站上有一个演示页面，我正在学习如何从脚本调用webservice 这是我的页面 http://applicazioni.vsc300.it/Mediweb2015/Prova.aspx

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>


 <input name="TXT_CognomePaziente" type="text" id="TXT_CognomePaziente" name="TXT_CognomePaziente" />

＆＃13;

' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
<System.Web.Script.Services.ScriptService()> _
<WebService(Namespace:="http://tempuri.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
 Public Class Service
    Inherits System.Web.Services.WebService


    '   <WebInvoke(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest, Method = "GET")>
    <WebMethod()> _
    <ScriptMethod(ResponseFormat:=ResponseFormat.Json)> _
    Public Function CercaPaziente(IDPaziente As Integer) As String
        Dim serialiser As JavaScriptSerializer = New JavaScriptSerializer()

        Dim Paz As New CLS_Paziente
        Paz.GetCercaAnagrafica(IDPaziente)

        Dim serializer As JavaScriptSerializer = New JavaScriptSerializer()
        Dim serializedItems As String = serializer.Serialize(Paz)

        Return serializedItems
    End Function

End Class

＆＃13;

这是服务：

{{1}}

它返回一个错误，只能从脚本中调用类定义中带有[ScriptService]属性的Web服务。 但我启用了它！我该怎么办？

来自this doc：

如果将多个属性应用于单个程序元素，则属性将包含在一组尖括号中，并用逗号分隔。例如：

<Obsolete(), WebMethod()> 
Public Function PageCount(strURL As String) As Integer

（顺便说一下，这很难找到。我无法在MSDN上的任何地方找到它。）所以，这不是你的代码所做的，.NET编译器可能忽略了你的属性共。试试这个，看它是否有效：

<System.Web.Script.Services.ScriptService(), _
WebService(Namespace:="http://tempuri.org/"), _
WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1), _
Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()>
Public Class Service
Inherits System.Web.Services.WebService

允许从脚本调用webservice
