JavaScript toLocaleString()

❮ Назад JavaScript Справочник чисел Далее ❯

Пример

Отформатируйте число в строку, используя специфику локали ФИНЛЯНДИИ:

var num = new Number(1000000).toLocaleString("fi-FI");
Попробуйте сами »

Определение и использование

Метод toLocaleString() преобразует число в строку, используя формат локального языка.

Язык по умолчанию зависит от настройки локали на вашем компьютере.

Поддержка браузера

Параметры locales и options не поддерживались до ECMAScript 5, и эти версии браузера:

toLocaleString() Да Да Да Да Да
locales 24 11 29 10 15
options 24 11 29 10 15

Синтаксис

number.toLocaleString(locales, options)
