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:
复制代码 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：
复制代码 代码如下:
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：
复制代码 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>
