Jquery Ajax学习实例4 向WebService发出请求，返回实体对象的异步调用

一、WebService.asmx：

处理业务数据，在GetPerson方法中产生Person实体类数据，供JqueryRequest.aspx调用，代码如下:

[WebMethod] 
public Person GetPerson(string name, int age, string address) 
{ 
Person p = new Person() 
{ 
Name = name, 
Age = age, 
Address = address 
}; 
return p; 
}

二、Person.cs实体类：

public class Person 
{ 
private string _name; 
public string Name 
{ 
get { return _name; } 
set { _name = value; } 
} 
private int _age; 
public int Age 
{ 
get { return _age; } 
set { _age = value; } 
} 
private string _address; 
public string Address 
{ 
get { return _address; } 
set { _address = value; } 
} 
}

三、AjaxRequest.aspx

通过点击按钮来请求WebService.asmx的GetPerson(string name, int age, string address)方法，获取Person实体数据。代码如下：

<script type="text/javascript" language="javascript"> 
function BtnPerson_Click() { 
$.ajax({ 
url: "WebService.asmx/GetPerson", 
data: { name: "Windy", age: 18, address: "Shanghai China" }, 
type: "post", 
success: function(data, status) { 
var obj = $(data); 
var name = obj.find("Name").text(); 
var age = obj.find("Age").text(); 
var address = obj.find("Address").text(); 
alert("Name:" + name + " Age:" + age + " Address:" + address); 
} 
}); 
} 
</script>
