JavaScript中如何反序列化json字符串呢?

有如下两种方法:

(1)使用万能的eval

Js代码  

1. var jsonText = '{"name":"acwong","age":23,"address":{"province":"GuangDong","city":"GuangZhou"},"friends":["bc","cc","dc"],"blog":"http://acwong.org"}';  
2.   
3.         var person = eval("("+jsonText+")");  

 运行结果:

 

 

(2)使用JSON.parse

Js代码  

1. var jsonText = '{"name":"acwong","age":23,"address":{"province":"GuangDong","city":"GuangZhou"},"friends":["bc","cc","dc"],"blog":"http://acwong.org"}';  
2.   
3.         var person = JSON.parse(jsonText);  
4.   
5.         console.log(person);  

 运行结果:

 

JSON对象结构如下:

 可以看出它有两个方法,分别是: parse()用于反序列化 和stringify()用于序列化为字符串
