Use variable as key to parse json [duplicate]

I have a var, let's say

var product = "something"

I have a json file that looks like

{
   "something": [
     {
        "price": "2000"
     }
   ], 
....

I need to access "price" from "something", so I'm trying

data.product.price

and it gives me undefined. I can easily get price value using data.something.price , but in my case it won't work because var product is dinamic value, so I need help with parsing my json, using my var as a key.

Solution 1:

You will have to use square brackets here, and also, your price is inside an array so you need to access it using [0]

data[product][0].price

Here, I select something object using data[product] and later, to select the first object in the array, I used [0] and then I select price key.

var product = 'something';

$.get('https://api.jsonbin.io/v3/b/596b31ce194a6c7f2b90406e', function(data) {
  console.log(data[product][0].price);
});
