这是一个实验中的功能
此功能某些浏览器尚在开发中，请参考浏览器兼容性表格以得到在不同浏览器中适合使用的前缀。由于该功能对应的标准文档可能被重新修订，所以在未来版本的浏览器中该功能的语法和行为可能随之改变。

只读属性 NavigatorLanguage.languages 返回一个 DOMString 的数组，数组内容表示网站访客所使用的语言。使用 BCP 47 语言标签来描述不同的语言。在返回的数组中，最适合当前用户的语言将会被排到数组的首位。

navigator.language 的值是该属性返回数组的第一个元素 [3]。（但它基于系统语言设置。）

当该值发生改变，即最适合用户的语言被改变，事件languagechange 将会在 Window 对象下触发。

在每一个HTTP请求上的来自用户浏览器的HTTP协议头 Accept-Language 使用相同的来自 navigator.languages 属性的语言值，除了特殊的 qvalues （权重值）字段（如：en-US;q=0.8）。

语法

preferredLanguages = globalObj.navigator.languages

navigator.language   //"en-US"
navigator.languages  //["en-US", "zh-CN", "ja-JP"]
