Jquery调用webService的四种方法
1、编写4种WebService方法
[WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ScriptService] //令WebService成功传入Json参数,并以Json形式返回结果 [GenerateScriptType(typeof(Person))] //不是必要,但推荐添加(如果Person里面再嵌套另一个复杂类型,则必要声明) [ToolboxItem(false)] public class WebService1 : System.Web.Services.WebService { /// /// 无任何参数 /// /// [WebMethod] public string HelloWorld() { return "Hello World"; } /// /// 传入参数 /// /// /// [WebMethod] public string Hello(string name) { return string.Format("Hello {0}", name); } /// /// 返回泛型列表 /// /// /// [WebMethod] public List<int> CreateArray(int i) { List<int> list = new List<int>(); while (i >= 0) { list.Add(i--); } return list; } /// /// 返回复杂类型 /// /// /// /// [WebMethod] public Person GetPerson(string name, int age) { return new Person() { Name = name, Age = age }; } } /// /// 复杂类型 /// public class Person { public string Name { get; set; } public int Age { get; set; } }
2、编写js调用以上方法
