导航器。用于IE的userLanguage

窗口.导航员.萤火虫/歌剧/safari语言

我想分享我的代码，因为它的工作，它是不同于其他给出的答案。 在这个例子中，如果你说法语(法国，比利时或其他法语语言)，你会被重定向到法语页面，否则会重定向到英语页面，这取决于浏览器的配置:

<脚本type = " text / javascript”> 美元(文档)。Ready (function () { var userLang = navigator。||导航语言; if (userLang.startsWith("fr")) { Window.location.href = '../fr/index.html'; ｝ 其他{ Window.location.href = '../en/index.html'; ｝ })； > < /脚本

导航器。用于IE的userLanguage

窗口.导航员.萤火虫/歌剧/safari语言

I can't find a single reference that state that it's possible without involving the serverside.

MSDN上:

navigator.browserLanguage navigator.systemLanguage navigator.userLanguage

从browserLanguage:

In Microsoft Internet Explorer 4.0 and earlier, the browserLanguage property reflects the language of the installed browser's user interface. For example, if you install a Japanese version of Windows Internet Explorer on an English operating system, browserLanguage would be ja. In Internet Explorer 5 and later, however, the browserLanguage property reflects the language of the operating system regardless of the installed language version of Internet Explorer. However, if Microsoft Windows 2000 MultiLanguage version is installed, the browserLanguage property indicates the language set in the operating system's current menus and dialogs, as found in the Regional Options of the Control Panel. For example, if you install a Japanese version of Internet Explorer 5 on an English (United Kingdom) operating system, browserLanguage would be en-gb. If you install Windows 2000 MultiLanguage version and set the language of the menus and dialogs to French, browserLanguage would be fr, even though you have a Japanese version of Internet Explorer. Note This property does not indicate the language or languages set by the user in Language Preferences, located in the Internet Options dialog box.

此外，它看起来像是browserLanguage被弃用了，因为IE8没有列出它

如果您正在开发Chrome应用程序/扩展使用Chrome。i18n API。

chrome.i18n.getAcceptLanguages(function(languages) {
  console.log(languages);
  // ["en-AU", "en", "en-US"]
});

I came across this piece of code to detect browser's language in Angular Translate module, which you can find the source here. I slightly modified the code by replacing angular.isArray with Array.isArray to make it independent of Angular library. var getFirstBrowserLanguage = function () { var nav = window.navigator, browserLanguagePropertyKeys = ['language', 'browserLanguage', 'systemLanguage', 'userLanguage'], i, language; // support for HTML 5.1 "navigator.languages" if (Array.isArray(nav.languages)) { for (i = 0; i < nav.languages.length; i++) { language = nav.languages[i]; if (language && language.length) { return language; } } } // support for other well known properties in browsers for (i = 0; i < browserLanguagePropertyKeys.length; i++) { language = nav[browserLanguagePropertyKeys[i]]; if (language && language.length) { return language; } } return null; }; console.log(getFirstBrowserLanguage());
