ASP.NET AJAX Beta2 调用本地WebService的一些改变

作者:凯旋网络来源:凯旋网络

发现最新版本的改动很大,下面就测试情况作一下说明(这里借用官方的例子):

1、首先建一个WebService 文件(HelloWorldService.asmx),代码如下:
 
<%@ WebService Language="C#" Class="Samples.AspNet.HelloWorldService" %>

using System;
using System.Web;
using System.Web.Services;
using System.Xml;
using System.Web.Services.Protocols;
using Microsoft.Web.Script.Services;

namespace Samples.AspNet
{

    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [ScriptService]
    public class HelloWorldService : System.Web.Services.WebService
    {

        [WebMethod]
        public string HelloWorld(String query)
        {
            string inputString = Server.HtmlEncode(query);
            if (!String.IsNullOrEmpty(inputString))
            {
                return String.Format("Hello, you queried for {0}. The "
                  + "current time is {1}", inputString, DateTime.Now);
            }
            else
            {
                return "The query string was null or empty";
            }
        }
    }
}
这里要说明的是[ScriptService] 属性,只有加上这个性属性,才能在页面中通过js进行异步调用;

2、建一个调用页面(AjaxScript1.aspx),如下:
<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

  <head id="Head1" runat="server">
    <title="测试一" />
    <style type="text/css">
      body { font: 11pt Trebuchet MS;
        font-color: #000000;
        padding-top: 72px;
        text-align: center }

      .text { font: 8pt Trebuchet MS }
    </style>

   </head>
   <body>
   <form id="Form1" runat="server">
   <asp:ScriptManager runat="server" ID="scriptManager">
      <Services>
      &n
