1.创建jason，并JSON.stringify()将之转换为字符串。

直接使用var customer={}, 然后直接customer.属性就可以直接赋值了。

也可以var customer = { CustomerName: CustomerName, CustomerAddress: CustomerAddress } 这样创建，它会自动将:前面的CustomerName视作属性名并加上双引号，并将后面的CustomerName当作属性值，读取变量值后也加上双引号，当然，这不如上面的方式面向对象。

提交表单前，要使用JSON.stringify()方法将jason对象转换为字符串。

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebAppJason._Default" %>            
                 
     
    
      
        
               
               
               
               
                        
               
       
      
    
     

2.在C#中，引用system.web.extension.dll，并using System.Web.Script.Serialization，然后直接用JavaScriptSerializer的Deserialize方法把字符串反序列化为Customer对象使用了，非常简单方便。

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.Script.Serialization;namespace WebAppJason{    public class Customer {        public string CustomerName = "";       public string CustomerAddress = "";    }    public partial class _Default : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            string custr = this.customer.Value;            if (custr != null && custr.Length > 0)            {                JavaScriptSerializer jsc = new JavaScriptSerializer();                Customer c = jsc.Deserialize
     
      (custr);                this.CustomerName0.Value = c.CustomerName;                this.CustomerAddress0.Value = c.CustomerAddress;            }        }    }}
     

3.使用JSON.parse()将字符串转回jason

function abc() {                var CustomerName = document.getElementById("CustomerName").value;                var CustomerAddress = document.getElementById("CustomerAddress").value;                var customer = {};                customer.CustomerName = CustomerName;                customer.CustomerAddress = CustomerAddress;                customer = JSON.stringify(customer);                //alert(customer);                var c2 = JSON.parse(customer);                alert(c2.CustomerName + " " + c2.CustomerAddress);                document.getElementById("customer").value = customer;            }
