Exploring nested JSON data to access specific elements

When I use console.log(responseJSON), it prints the following JSON format logs on the screen. However, I am specifically interested in printing only the latlng values. When I attempt to access the latlng data with console.log(responseJSON.markers.latlng) or console.log(responseJSON.markers), it returns undefined.

Array [
Object {
  "markers": Object {
    "index": "1",
    "latlng": Object {
      "latitude": "40.3565",
      "longitude": "27.9774",
    },
  },
},
Object {
  "markers": Object {
    "index": "3",
    "latlng": Object {
      "latitude": "40.3471",
      "longitude": "27.9598",
    },
  },
},
Object {
  "markers": Object {
    "index": "2",
    "latlng": Object {
      "latitude": "40",
      "longitude": "27.9708",
    },
  },
},]

I am seeking guidance on how to correctly print and retrieve specific data, like so:

console.log(responseJSON.markers.latlng);

Answer №1

When working with the response, remember that it is in array format. Make sure to use an index to access each element within the array.

For example, you can access specific elements using syntax like responseJSON[0].markers.latlong.

Answer №2

To access the inner contents of an array of objects, you can utilize a straightforward forEach loop

var dataPoints= [
 {
  "markers":  {
    "index": "1",
    "latlng":  {
      "latitude": "40.3565",
      "longitude": "27.9774",
    },
  },
},
 {
  "markers":  {
    "index": "3",
    "latlng":  {
      "latitude": "40.3471",
      "longitude": "27.9598",
    },
  },
},
 {
  "markers":  {
    "index": "2",
    "latlng":  {
      "latitude": "40",
      "longitude": "27.9708",
    },
  },
},];

dataPoints.forEach(function(item){
   console.log(item.markers.latlng)
})
