發現最新版本的改動很大，下面就測試情況作一下說明(這裡借用官方的例子)：
1、首先建一個WebService 文件（HelloWorldService.asmx），代碼如下：
<%@ 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";
}
}
}
}
這裡要說明的是[ScriptService] 屬性，只有加上這個性屬性，才能在頁面中通過JS進行異步調用；
2、建一個調用頁面(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="測試一" />
<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>
<ASP:ServiceReference path="~/HelloWorldService.asmx" />
</Services>
</ASP:ScriptManager>
<div>
Search for
<input id="SearchKey" type="text" />
<input id="SearchButton" type="button" value="Search"
onclick="DOSearch()" />
</div>
</form>
<hr style="width: 300px" />
<div>
<span id="Results"></span>
</div>
<script type="text/Javascript">
function DOSearch()
{
var SrchElem = document.getElementById("SearchKey");
Samples.ASPNet.HelloWorldService.HelloWorld(SrchElem.value, OnRequestComplete);
}
function OnRequestComplete(result)
{
var RsltElem = document.getElementById("Results");
RsltElem.innerHtml = result;
}
</script>
</body>
</Html>
注意，這裡的<ASP:ScriptManager runat="server" ID="scriptManager">
<Services>
<ASP:ServiceReference path="~/HelloWorldService.asmx" />
</Services>
</ASP:ScriptManager>
放在<form>中了。
