json数据与字符串相互转化的例子

json与字符串之间的转换，本文分享一个小例子。

 

json转成string[需要引用json2.js文件]： 

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: 

var str="[{id:\'id\',name:\'Spring\'},{id:\'id2\',name:\'Jane\'}]"; 

var json=$.parseJSON(str); 

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