asp.net ajax跟atlas有了很大不同。从这个简单的例子中可以看出几点。<1>新建一个asp.net ajax-enabled web site<2>页面布局。Server Controls的标签前缀(Tag Prefix)由atlas变为asp;
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="HelloWorld" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"><html><head runat="server"> <title>Hello</title></head><body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"> <Services> <asp:ServiceReference Path="~/HelloWorldService.asmx" /> </Services> </asp:ScriptManager> <div> 你的名字: <input type="text" maxlength="20" id="name" /> <input type="button" id="button1" value="问候" onclick="SayHello()" /> <div id="result"></div> </div> </form> </body></html><3>客户端脚本。调用服务的方法有些许改变。可以指定默认的回调方法。<script type="text/javascript"> function SayHello() { var fs = HelloWorldService; fs.set_defaultSucceededCallback(OnShow); fs.HelloWorld(document.getElementById("name").value); } function OnShow(result) { var s = document.getElementById("result"); s.innerText = result; }</script>
<4>HelloWorldService服务代码。为了能使服务被asp.net ajax客户端调用，必须给服务指明[ScriptService]属性（为了使用这一属性，需要引用Microsoft.Web.Script.Services命名空间）。 1using System; 2using System.Web.Services; 3using System.Web.Services.Protocols; 4using Microsoft.Web.Script.Services; 5 6[WebService(Namespace = "http://tempuri.org/")] 7[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] 8[ScriptService] 9public class HelloWorldService : System.Web.Services.WebService {1011 public HelloWorldService () {1213 //Uncomment the following line if using designed components 14 //InitializeComponent(); 15 }1617 [WebMethod]18 public string HelloWorld(string name) {19 string hello = String.IsNullOrEmpty(name) ? "无名氏" : name;20 hello += "你好,当前服务器时间是：";21 hello += DateTime.Now.ToUniversalTime();22 return hello;23 }24 25}http://www.cnblogs.com/sharpaxe/archive/2006/10/24/538395.html
