9、JSON.parse()和JSON.stringify()

parse()

    是将 string 字符串解析成  JSON对象

    var str = '{"name":"lee","age","25","gender","male"}';

    JSON.parse(str);

            obj:

                    name:"lee"

                    age:"25"

                    gender:"male"

stringify()

    是将对象解析成JSON字符串

    var obj = {

                        "name":"lee",

                        "age":25,

                        "gender":"male"

                    }

    JSON.stringify(obj);

            var str = '{"name":"lee","age":"25","gender":"male"}';
