请教asp.net ajax 调用webservice问题,请进

varvarbbs 2008-12-29 11:16:26

我在页面上调用WebService的时候,出现了"WS未定义",WS是WebService的名字,我按照书上的代码还有网上的代码测试了,都是这个问题

WebService代码



using System;

using System.Data;

using System.Web;

using System.Collections;

using System.Web.Services;

using System.Web.Services.Protocols;

using System.ComponentModel;

using System.Web.Script.Services;



namespace AJAXDemo

{

    /**/

    /// <summary> 

    /// http://meil.livebaby.cn

    /// </summary> 

    [WebService(Namespace = "http://tempuri.org/")]

    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

    [ScriptService]

    public class WS : System.Web.Services.WebService

    {



        public WS()

        {



            //如果使用设计的组件，请取消注释以下行 

            //InitializeComponent(); 

        }



        [WebMethod]

        [ScriptMethod(UseHttpGet = true)]

        public string HelloWorld(String query)

        {

            string inputString = Server.HtmlEncode(query);

            if (!String.IsNullOrEmpty(inputString))

            {

                return String.Format("hello, {0}. ", inputString);

            }

            else

            {

                return "query string is null or empty";

            }

        }



    }

}

以上Path路径是否正确？？？是否区分大小写！
