javascript中对json数据的处理

目前我们有两种常见的手段，在javascript中，对json数据进行处理：包括将一个json对象转换为字符串，以及将一个字符串还原为一个json对象
1. 使用json2.js处理
http://www.json.org/json2.js
大概只有2k，很好很强大
 
示例代码：

var employee = {
Name: "chenxizhang",
Country: "China",
Orders: [
{ OrderID: 10248 },
{ OrderID: 10249 }
]
};

//发送POST请求，数据也是json格式。但数值部分需要转换为字符串
$.post("EmployeeHandler.ashx", { data: JSON.stringify(employee) }, function(result) {
var r = JSON.parse(result);
alert(r.Message);
});

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

 

2. 使用MicrosoftAjax.js处理

示例代码：

var employee = {
Name: "chenxizhang",
Country: "China",
Orders: [
{ OrderID: 10248 },
{ OrderID: 10249 }
]
};

$.post("EmployeeHandler.ashx", { data: Sys.Serialization.JavaScriptSerializer.serialize(employee) }, function(result) {
var r = Sys.Serialization.JavaScriptSerializer.deserialize(result);
alert(r.Message);
});

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

 

他们的结果是一模一样的
