Javascript loop through staggered JSON object

[venomtail]

I take in json data that I want to go through and use the fields that I need.

Data looks like this

{
  "Part1": {
    "Field_1": {
      "Type": "",
      "Name": "",
      "special": ""
    },
    "Field_2": {
      "Type": "",
      "Name": "",
      "special": ""
    },
    "Field_3": {
      "Type": "",
      "Name": "",
      "special": ""
    },
    "Field_4": {
      "Type": "",
      "Name": "",
      "special": ""
    },
    "Field_5": {
      "Type": "",
      "Name": "",
      "special": ""
    },
    "Field_6": {
      "Type": "",
      "Name": "",
      "special": ""
    },
    "Field_7": {
      "Type": "radio",
      "Name": "RadioDefault",
      "special": "for"
    },
    "Field_8": {
      "Type": "radio",
      "Name": "RadioDefault",
      "special": "for"
    },
    "Field_9": {
      "Type": "radio",
      "Name": "RadioDefault",
      "special": "for"
    }
  },
  "Part2": {
    "Field_1": {
      "Type": "",
      "Name": "",
      "special": ""
    },
    "Field_2": {
      "Type": "",
      "Name": "",
      "special": ""
    },
    "Field_3": {
      "Type": "",
      "Name": "TargetID38",
      "special": "rows=\"2\""
    },
    "Field_4": {
      "Type": "",
      "Name": "",
      "special": ""
    },
    "Field_5": {
      "Type": "",
      "Name": "",
      "special": ""
    },
    "Field_6": {
      "Type": "",
      "Name": "",
      "special": ""
    }
  }
}

I've parsed the whole json into an object

certElementData = Object.entries(JSON.parse(result));

And tried to loop through the data.

 

Getting unlucky here. Maybe I should go back to simple for loops but I want to try out the for in and for of loops.

 

For of loops do well until I get to the Field_'s part as that refuses to go into a array and stays being an object. If I try to use a for in loop, that loop will wipe any following data, saying that sure it'll now loop through to Field_9 but that's it, there's no data after it.

 

How can I retain all the data yet get to the bottom info such as "Name":"" and "Type":"" that I need.

 

Have a look at the initial start parse as well. What if I'm needlessly parsing them and made a mistake at the start?

 

Thanks.

I'm starting to think the json itself is set up wrong.

Your data is an object. Not an array. JSON encoded arrays will have square brackes. Objects have curly braces

For of is for iterating over array's.

For in for loop though an objects properties.

 

You can convert your data object into an array using Object.entries(data)

Use Object.Keys() https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys

 

You can do

const object1 = {
  a: 'somestring',
  b: 42,
  c: false,
};

for (let x of Object.keys(object1)) {
  console.log(x + " -> " + object1[x]);
}

Edit:

Yeah, entries() should work as well. Try this:

const object1 = {
  a: 'somestring',
  b: 42,
  c: {
    d: "d",
    e: "e"
  }
};

for (const [key, value] of Object.entries(object1)) {
  console.log(`${key}: ${value}`);
}
