JS JSON串转换

JS 对象转为json字符串

var obj={name:"小明",age:"15"}

JSON.srtingify(obj) 

//"{"name":"小明","age":"15"}" 

JSON字符串转为 JS 对象

var str="{"name":"小明","age":"15"}" 

JSON.parse(str)

// {name: "小明", age: "15"}

或者使用jQuery

var str="{"name":"小明","age":"15"}" 

jQuery.parseJSON(str)

// {name: "小明", age: "15"}

JS数组转JSON

var arr=[1,2,3,{a:1,b:2}];

JSON.stringify(arr)

//'[1,2,3,{"a":1,"b":2}]'

JSON 转 JS数组

var str='[1,2,3,{"a":1,"b":2}]'

JSON.parse(str)

//[1,2,3,{a:1,b:2}]
