Ewe*_*ton 5 javascript asp.net ajax web-services asp.net-ajax
我正在尝试调用WebService
我完全按照本文中的描述进行了操作
http://viralsarvaiya.wordpress.com/2010/03/23/calling-web-service-from-java-script-in-asp-net-c/
查看firebug的控制台,我可以看到我的函数已执行并返回了预期的数据,但我的回调函数(OnComplete,OnError,OnTimeOut)从未执行过.
怎么了？
这是代码(文章的相同代码)Service.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
[WebService(Namespace = "http://Localhost...xys/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
[System.Web.Script.Services.ScriptService()]
public class Service : System.Web.Services.WebService
{
public Service () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public string HelloWorld(string strNoOfData)
{
return strNoOfData;
}
}
Default.aspx的
