json数据与字符串的相互转化示例

json转成string[需要引用json2.js文件]：

代码如下:

 
var arr=[{id:'id',name:'Spring'},{id:'id2',name:'Jane'}]; 
var str=JSON.stringify(arr); 

结果："[{id:'id',name:'Spring'},{id:'id2',name:'Jane'}]"

string转化为json:

代码如下:

 
var str="[{id:'id',name:'Spring'},{id:'id2',name:'Jane'}]"; 
var json=$.parseJSON(str); 

结果：[{id:'id',name:'Spring'},{id:'id2',name:'Jane'}]
