Get information from varying objects in JSON

Question

I have this code (which is variant thought the time) in JSON

{
  "5780": {
    "app": "Bye",
    "name": "Hello World",
    "surname": "Friend"
  },
  "6654": {
    "app": "Hello",
    "name": "Hi",
    "surname": "godbye"
  }
}

I want to get the information from each section (for example the "app" section) an insert in a js variable. The problem is that the object title (5780 & 6654) change will change (at the same time, the sections information). So I need something like section[1].app = jsvariable1

Answer 1

First of all, your json is not valid so you have to check it(as i did in the code below) . So here's what i did :

var sections = {
  "5780": {
    "app": "Bye",
    "name": "Hello World",
    "surname": "Friend",
  },

  "6654": {
    "app": "Hello",
    "name": "Hi",
    "surname": "godbye",
  }

};


var index = [];

//setting the index array
for (var x in sections) {
  index.push(x);
}

console.log(sections[index[0]].app)
console.log(sections[index[1]].app)
