Intl.PluralRules object enables plural-sensitive formatting and plural-related language rules.

构造函数

Intl.PluralRules.PluralRules()

创建新的 Intl.PluralRules 对象。

静态方法

Intl.PluralRules.supportedLocalesOf()

Returns an array containing those of the provided locales that are supported without having to fall back to the runtime's default locale.

实例方法

Intl.PluralRules.prototype.resolvedOptions()

Returns a new object with properties reflecting the locale and collation options computed during initialization of the object.

Intl.PluralRules.prototype.select()

返回 String indicating which plural rule to use for locale-aware formatting.

范例

Using locales

This example shows some of the variations in localized plural rules. In order to get the format of the language used in the user interface of your application, make sure to specify that language (and possibly some fallback languages) using the locales argument:

// Arabic has different plural rules
new Intl.PluralRules('ar-EG').select(0);
// → 'zero'
new Intl.PluralRules('ar-EG').select(1);
// → 'one'
new Intl.PluralRules('ar-EG').select(2);
// → 'two'
new Intl.PluralRules('ar-EG').select(6);
// → 'few'
new Intl.PluralRules('ar-EG').select(18);
// → 'many'

To make full ICU (locale) data available for versions prior to 13, see Node.js documentation on the --with-intl option and how to provide the data.
