Change a JavaScript object into an array with different options while still maintaining the keys

Question

I am attempting to transform the following JavaScript object:

image_uploads: [
  0: {
    upload_id: 50,
  },
  1: {
    upload_id: 51,
  },
  2: {
    upload_id: 52,
  },
]

Into separate entries using this structure for inclusion in the body of a POST request:

image_uploads[0][upload_id] = 50
image_uploads[1][upload_id] = 51
image_uploads[2][upload_id] = 52

This may involve creating an array of those entries like so:

params: [
  "image_uploads[0][upload_id]": 50,
  "image_uploads[1][upload_id]": 51,
  "image_uploads[2][upload_id]": 52,
]

Thank you!

Answer №1

If you are looking to continuously add keys to an array, you can achieve that by following this method:

var car_models = [];
car_models.push({'model_id': 100});
car_models.push({'model_id': 101});
car_models.push({'model_id': 102});

After adding the keys, you can retrieve them as shown below:

car_models[0]['model_id']; // 100
car_models[1]['model_id']; // 101
car_models[2]['model_id']; // 102

To simplify the process of creating the array and accessing its elements, consider using loops.
