如何在 JavaScript 中将语言代码转换为语言名称？

Question

我使用以下方式获取浏览器的语言代码：

var lang = window.navigator.language;

这将返回代码（即 en-US）。如何将其转换为语言名称（即英语）？

Answer 1

Javascript 有一个 API，用于Intl使用所选语言将语言转换为字符串。

请参阅https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/DisplayNames

const languageNames = new Intl.DisplayNames(['en'], {
  type: 'language'
});

console.log('en', languageNames.of('en'))
console.log('en-US', languageNames.of('en-US'))
console.log('es-MX', languageNames.of('es-MX'))
