JS对象与JSON格式数据相互转换

一、JS对象转换成为JSON 

var   jsonData = {};
jsonData.MainCmdID = 1;
jsonData.SubCmdID = 1;
var toStr = JSON.stringify(jsonData);
alert(toStr);

 

二、JSON转换成为JS 

var result2 = $.parseJSON( '{ "name": "CodePlayer", "age": 1 }' ); // 一个Object对象

alert( result2.name ); // CodePlayer

 

 

 

 

 

例:

 

var student = new Object(); 
student.name = "Lanny"; 
student.age = "25"; 
student.location = "China"; 
var json = JSON.stringify(student); 
alert(student); 

 

 

 

var student = new Object(); 
student.name = "Lanny"; 
student.age = "25"; 
student.location = "China"; 

// var json = JSON.stringify(student); 
alert(student);
