ScriptServiceAttribute Class
Indicates that a Web service can be invoked from script. This class cannot be inherited.
Namespace: System.Web.Script.Services
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
The ScriptServiceAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
 | ScriptServiceAttribute | Initializes a new instance of the ScriptServiceAttribute class. |
| Name | Description | |
|---|---|---|
| Equals | Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.) |
| GetHashCode | Returns the hash code for this instance. (Inherited from Attribute.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.) |
| Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
| _Attribute.GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
| _Attribute.GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
| _Attribute.GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
| _Attribute.Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
To invoke a Web service method from ECMAScript (JavaScript), you must apply the ScriptServiceAttribute attribute to the related Web service class. When you apply ScriptServiceAttribute to a Web service class definition that contains one or more methods with WebMethodAttribute applied, the proxy generation script creates a proxy object that corresponds to the Web service class.
For more information about using attributes, see Extending Metadata Using Attributes.
The following example demonstrates how to apply ScriptServiceAttribute to the Web service class definition so that its methods can be called from client script.
<%@ WebService Language="C#" Class="SimpleWebService" %> using System; using System.Web; using System.Web.Services; using System.Web.Services.Protocols; using System.Web.Script.Services; [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ScriptService] public class SimpleWebService : System.Web.Services.WebService { [WebMethod] public string GetServerTime() { string serverTime = String.Format("The current time is {0}.", DateTime.Now); return serverTime; } }
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
