如何在 JavaScript/Angular 中按货币名称将数字格式化为货币

Question

How to format number to currency by currency name?

I have dynamic numbers with only currency name ( ex: USD,INR etc). I don't have any local codes (like, en-US).

I would try this below way. But it is asking to provide local code('en-US').

var formatter = new Intl.NumberFormat('en-US', {
  style: 'currency',
  currency: 'USD',
});

formatter.format(2500)

But I don't have 'en-US' in my data base. I have only currency Name and Number.

So how could I format the the number to currency by Currency name?

Answer 1

Just pass undefined for the locale?

 const getFormattedCurrency = (currency, amount) => new Intl.NumberFormat(undefined, { style: 'currency', currency, }).format(amount); console.log(getFormattedCurrency('USD', 2500)); console.log(getFormattedCurrency('JPY', 2500)); console.log(getFormattedCurrency('EUR', 2500)); console.log(getFormattedCurrency('CNY', 2500)); console.log(getFormattedCurrency('AUD', 2500)); console.log(getFormattedCurrency('INR', 2500));
