Ext直接調用ASP.Net Ajax Webservice

ExtJS發布了2.1版，經過測試，這個版本可以直接調用ASP.Net Ajax的WebService，示例代碼如下：

1. WebService代碼：

using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

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

	[WebMethod]
	public string HelloWorld(string firstName, string lastName) {
		return string.Format("Hello {0} {1}", firstName, lastName);
	}

	[WebMethod]
	public string ExceptionMethod(int param) {
		throw new NotImplementedException("該方法未實現");
	}
}

2. 客戶端調用代碼：

function CallHelloWorld() {
	Ext.Ajax.request({
		url: 'TestWebService.asmx/HelloWorld', // Webservice的地址以及方法名
		jsonData: { firstName: 'AAA', lastName: 'BBB' }, // json 形式的參數
		method: 'POST', // poste 方式傳遞
		success: onSuccess,
		failure: onFailure
	});
}
function CallExceptionMethod() {
	Ext.Ajax.request({
		url: 'TestWebService.asmx/ExceptionMethod',
		jsonData: { param: 3 },
		method: 'POST',
		success: onSuccess,
		failure: onFailure
	});
}
function onSuccess(request, options) {
	// 服務器返回json形式的結果
	var result = Ext.util.JSON.decode(request.responseText);
	Ext.Msg.alert('è?”?????“???', result.d);
}
function onFailure(request, options) {
	alert(request.responseText);
}

3. 返回結果分別為：
