JSON.parse()和JSON.stringify()

原文链接

parse用于从一个字符串中解析出json对象,如
var str = '{"name":"huangxiaojian","age":"23"}'
结果：
JSON.parse(str)
Object
age: "23"
name: "huangxiaojian"
__proto__: Object
注意：单引号写在{}外，每个属性名都必须用双引号，否则会抛出异常。
stringify()用于从一个对象解析出字符串，如
var a = {a:1,b:2}
结果：
JSON.stringify(a)
"{"a":1,"b":2}"

JSON.stringify(NeedProds)
