我一直在尝试使用JavaScript检测浏览器语言首选项。
如果我在IE的“工具>Internet选项>常规>语言”中设置浏览器语言，如何使用JavaScript读取此值?
火狐也有同样的问题。我无法检测工具>选项>内容>语言使用导航器.language的设置。
使用导航器。userLanguage，它检测设置通过 打开>ControlPanel>RegionalandLanguageOptions>Regional Options选项卡。
我已经用navigator测试过了。browserLanguage和navigator。systemLanguage但都不返回第一个设置的值(Tools>InternetOptions>General>Languages)
我找到了一个详细讨论这个问题的链接，但这个问题仍然没有答案:(

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

值得注意的是，维基媒体的通用语言选择器库有这样做的钩子: https://www.mediawiki.org/wiki/Extension:UniversalLanguageSelector
请参见resources/js/ext.ul .init.js中的getFrequentLanguageList函数。直接联系: https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/extensions/UniversalLanguageSelector.git;a=blob;f=resources/js/ext.uls.init.js;hb=HEAD
它仍然取决于服务器，或者更具体地说，取决于MediaWiki API。我展示它的原因是，它可以提供一个很好的示例，用于获取关于用户语言的所有有用信息:浏览器语言、Accept-Language、地理位置(从CLDR获取国家/语言信息)，当然还有用户自己的站点首选项。
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());
如果你只需要支持某些现代浏览器，那么你现在可以使用:
navigator.languages
它按用户指定的顺序返回用户的语言首选项数组。
截至目前(2014年9月)，这项工作: 铬(v37), Firefox (v32)和 歌剧(v24)
但不是在: IE (v11)
导航器。用于IE的userLanguage
窗口.导航员.萤火虫/歌剧/safari语言
如果你使用的是ASP . net MVC，你想从JavaScript中获得accept - languages头，那么这里有一个不涉及任何异步请求的变通例子。
在你的.cshtml文件中，将头部安全地存储在div的data- attribute中:
<div data-languages="@Json.Encode(HttpContext.Current.Request.UserLanguages)"></div>
然后你的JavaScript代码可以访问这些信息，例如使用JQuery:
<script type="text/javascript">
$('[data-languages]').each(function () {
var languages = $(this).data("languages");
for (var i = 0; i < languages.length; i++) {
var regex = /[-;]/;
console.log(languages[i].split(regex)[0]);
}
});
</script>
当然，您也可以像其他人提到的那样，对其他服务器技术使用类似的方法。
