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>
