CodePudding user response：

You could use Object.keys to achieve this

var json = {
  "results": {
    "ALL": {
      "currencyName": "Albanian Lek",
      "currencySymbol": "Lek",
      "id": "ALL"

      "currencyName": "East Caribbean Dollar",
      "currencySymbol": "$",
      "id": "XCD"
    }
  }
]

const res = Object.keys(json.results).map(key => ({currencyName: json.results[key].currencyName,id: json.results[key].id}))

console.log(res)

CodePudding user response：

You can use Object.keys() to extract the result from the response and then the spread operator to get all keys of each item without even knowing their names. Finally, you can iterate over the result array and display each item id and currencyName. This array can be accessed in an Angular template where you can use *ngFor to display all items.

const jsonResponse = {
  "results": {
    "ALL": {
      "currencyName": "Albanian Lek",
      "currencySymbol": "Lek",
      "id": "ALL"
    },
    "XCD": {
      "currencyName": "East Caribbean Dollar",
      "currencySymbol": "$",
      "id": "XCD"
    },
    "EUR": {
      "currencyName": "Euro",
      "currencySymbol": "€",
      "id": "EUR"
    },
  }
}

const itemsArray = Object.keys(jsonResponse.results).map((key) => ({...jsonResponse.results[key]}))

itemsArray.forEach((item) => console.log(item.id, item.currencyName));
