bracket notation + javascript

This is my object :

Customer{"id": "0001", "name": "ivan" , "country" {"city" : "Peru"}}

So: Whats the correct form to use brakets? the context is in a jquery each:

$. each (datos, function (index, data) { }

1° data["country"["city"]]   >> the result should be "Peru"
2° data["country"]["city"]   >> the result should be "Peru"

or whats is the form correct?

Solution

  • I belive you are saying that your object is :

    Customer  = {
   id: "0001",
   name: "ivan",
   country: {
      city : "Peru"
   }
}

    In this case your syntax would be either

    Customer.country.city

    or

    Customer["country"]["city"]

    or any mix of this two

    Note also that Customer[country[something]] can also be valid syntax, but doesnt seem to be in your case

    Customer  = {
   id: "0001",
   name: "ivan",
   country: {
      city : "Peru"
   }
}


country = {
   key: 'country'
}

Customer[country['key']]['city']

    would also return you city Peru
