在php jquery中的json对象中获取密钥

Question

I am returning a json data to jquery using php. what i want is to access the keys inside the json. i followed a tutorial and used json stringify but im not able to access the keys.

json data :

[
    {"id":"1","movie_name":"spiderman","releases_on":"20th August 2018"},
    {"id":"2","movie_name":"batman","releases_on":"21st August 2018"},
    {"id":"3","movie_name":"fast and furious 6","releases_on":"22nd August 2018"}
]

code in jquery:

var json = data;
var obj = JSON.stringify(json);
console.log(obj[1].id);

Answer 1

you have to use JSON.parse(json). then, you can do it.

Answer 2

JSON.stringify() will take your JSON object and convert it to a JSON string (here which is response).

JSON.parse() will take stringified JSON and convert it to object so that you can access via . operator

for example,

var a = { name: "John", age: 20 }
console.log(typeof a)   // object
var out = JSON.stringify(a)
console.log(typeof out)  // string
var res = JSON.parse(out) 
console.log(typeof res)  // object

I hope you got it....
