Tips for traversing through individual elements within an array present in the request payload

Looking to extract specific values from an array in req.body. I want to loop through and retrieve data like quantity_1 and quantity_2 separately. How can I achieve this? Here is a snippet of my array from req.body:

{ 
  quantity_1: '9',
  item_name_1: 'Event Cap Nike',
  amount_1: '599',
  shipping_1: 'undefined',
  shipping2_1: 'undefined',
  quantity_2: '1',
  item_name_2: 'Plaza',
  amount_2: '1000',
  shipping_2: 'undefined',
  shipping2_2: 'undefined',
  cmd: '_cart',
  upload: '1',
  bn: 'MiniCart_AddToCart_WPS_US',
  business: ' ',
  currency_code: 'INR',
  return: ' ',
  cancel_return: ' ' }

Answer №1

  1. Remember, this is not an array but an object.

  2. To loop through the properties of the object, you can utilize methods like Object.keys.

 var myObj = { quantity_1: '9',
  item_name_1: 'Event Cap Nike',
  amount_1: '599',
  shipping_1: 'undefined',
  shipping2_1: 'undefined',
  quantity_2: '1',
  item_name_2: 'Plaza',
  amount_2: '1000',
  shipping_2: 'undefined',
  shipping2_2: 'undefined',
  cmd: '_cart',
  upload: '1',
  bn: 'MiniCart_AddToCart_WPS_US',
  business: ' ',
  currency_code: 'INR',
  return: ' ',
  cancel_return: ' ' }
  
  Object.keys(myObj).forEach(property => {
  
      console.log(myObj[property]);
  })

Answer №2

Essentially, what we have here is not an array, but rather an object. To access and display its values, you can utilize a for ... in loop like so:

const myObj = { quantity_1: '9',
  item_name_1: 'Event Cap Nike',
  amount_1: '599',
  shipping_1: 'undefined',
  shipping2_1: 'undefined',
  quantity_2: '1',
  item_name_2: 'Plaza',
  amount_2: '1000',
  shipping_2: 'undefined',
  shipping2_2: 'undefined',
  cmd: '_cart',
  upload: '1',
  bn: 'MiniCart_AddToCart_WPS_US',
  business: ' ',
  currency_code: 'INR',
  return: ' ',
  cancel_return: ' ' }

for(let key in myObj) {
    if(key in ["quantity_1", "item_name_1", "amount_1"]) {
        console.log(myObj[key]);
    }
}
