Javascript 中 ISO 639-1 代码中的语言名称

2022-01-18 00:00:00 internationalization javascript

我正在建立一个网站，人们可以在其中将语言信息与内容相关联.

I'm building a website where people can associate a language information to content.

网站大量使用 Javascript，与各种元素相关的语言信息在内部被视为 ISO 639-1 代码.

The website uses Javascript heavily and the language information associated to various elements is treated internally as an ISO 639-1 code.

如何以用户的语言显示语言名称列表?

How to show a list of language names - in the language of the user ?

推荐答案

在 new(ish) 国际 API:

There is a native support for this in the new(ish) Intl API:

let languageNames = new Intl.DisplayNames(['en'], {type: 'language'});
languageNames.of('fr');      // "French"
languageNames.of('de');      // "German"
languageNames.of('fr-CA');   // "Canadian French"
