例子
基本用法
在没有指定语言环境的基本使用中,返回默认语言环境中的格式化字符串和默认选项。这有助于区分单数和复数形式,例如“dog”和“dogs”。
var pr = new Intl.PluralRules(); pr.select(0); // → 'other' if in US English locale pr.select(1); // → 'one' if in US English locale pr.select(2); // → 'other' if in US English locale
运用 locales
这个例子展示了局部复数规则的一些变化。为了获得应用程序用户界面中使用的语言格式,请确保使用locales
参数指定该语言(可能还有一些备用语言):
// 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'
运用 options
可以查询查询结果使用options
参数进行自定义,该参数具有一个type
您可以设置的属性ordinal
。这对计算序数指标很有用,例如“第一”,“第二”,“第三”,“第四”,“42”等。
var pr = new Intl.PluralRules('en-US', { type: 'ordinal' }); pr.select(0); // → 'other' pr.select(1); // → 'one' pr.select(2); // → 'two' pr.select(3); // → 'few' pr.select(4); // → 'other' pr.select(42); // → 'two'
