c/c++常用代码之四爆炸输出，jason（纯干货）

常用代码之四：创建jason，jason转换为字符串，字符串转换回jason，c#反序列化jason字符串的几个代码片段

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” %>

<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>
           

<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>
           

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<Customer>(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;

        }
