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。

复制代码
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebAppJason._Default" %><head runat="server">    <title></title>        <meta http-equiv="X-UA-Compatible" content="IE=9" />        <script type="text/javascript">            function abc() {                var customer = {};                customer.CustomerName = document.getElementById("CustomerName").value;                customer.CustomerAddress = document.getElementById("CustomerAddress").value;                customer = JSON.stringify(customer);                //alert(customer);                document.getElementById("customer").value = customer;            }    </script></head><body>    <form id="form1" runat="server" >    <div>        <input type="text" id="CustomerName"  />        <input type="text" id="CustomerAddress"  />        <input type="text" id="customer" runat="server" />        <input type="button" id="button1" value="button1" onclick="abc()"  />        <asp:Button ID="Button2" runat="server" onclick="Button2_Click" Text="Button" />        &nbsp;        <input type="text" id="CustomerName0" runat="server"  />        <input type="text" id="CustomerAddress0" runat="server" /></div>    </form></body></html>
复制代码

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。

复制代码
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<Customer>(custr);                this.CustomerName0.Value = c.CustomerName;                this.CustomerAddress0.Value = c.CustomerAddress;            }        }    }}
复制代码

3.使用JSON.parse()将字符串转回jason

复制代码
            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;            }
