Question

有任何想法，我如何在Typescript或JS中分割这些：

{“AED”：“阿拉伯联合酋长国迪拉姆”，“AFN”：“阿富汗阿富汗人”，“所有人”：“阿尔巴尼亚人列克”}

我只想要这样的名字：

AED AFN ALL

Answer 1

你做错了，首先修改你的object到array of objects，如下所示

let currencies = [
  {
    code: "AED",
    fullName: "United Arab Emirates Dirham"

  },
  {
    code: "AFN",
    fullName: "Afghan Afghani"

  },
  {
    code: "ALL",
    fullName: "Albanian Lek"

  }
];

现在你可以像

那样遍历它

currencies.forEach(val => {
  //use val.code to get desired currencies codes
})

Answer 2

您可以使用Object.keys（link）从某个对象中提取所有键。

var countries = { "AED": "United Arab Emirates Dirham", "AFN": "Afghan Afghani", "ALL": "Albanian Lek" }
var codes = Object.keys( countries );
console.log( codes ); // [ "AED", "AFN", "ALL" ]
