Javascript方法:

var language = window.navigator.userLanguage || window.navigator.language;//returns value like 'en-us'

如果你正在使用jQuery。I18n插件，你可以使用:

jQuery.i18n.browserLang();//returns value like '"en-US"'

我有一个不同的方法，这可能会在未来帮助到一些人:

客户想要一个可以交换语言的页面。 我需要通过该设置格式化数字(不是浏览器设置/不是任何预定义的设置)

因此，我根据配置设置(i18n)设置了初始设置

$clang = $this->Session->read('Config.language');
echo "<script type='text/javascript'>var clang = '$clang'</script>";

后来在脚本中，我使用了一个函数来确定我需要的数字格式

function getLangsettings(){
  if(typeof clang === 'undefined') clang = navigator.language;
  //console.log(clang);
  switch(clang){
    case 'de':
    case 'de-de':
        return {precision : 2, thousand : ".", decimal : ","}
    case 'en':
    case 'en-gb':
    default:
        return {precision : 2, thousand : ",", decimal : "."}
  }
}

所以我使用了页面的设置语言，作为退步，我使用了浏览器设置。

这对测试也有帮助。

根据客户的不同，您可能不需要这些设置。

Let lang = window.navigator.languages ?window.navigator。[0]: null; || window.navigator.language || window.navigator.browserLanguage || window.navigator.userLanguage; let shortLang = lang; if (shortLang.indexOf('-') !== -1) shortLang = shortLang.split('-')[0]; if (shortLang.indexOf('_') !== -1) shortLang = shortLang.split('_')[0]; console.log(朗,shortLang);

我只需要主组件来满足我的需要，但是您可以轻松地使用完整的字符串。适用于最新的Chrome, Firefox, Safari和IE10+。

我刚想到这个。它结合了较新的JS解构语法和一些标准操作来检索语言和区域设置。

var [lang, locale] = (
    (
        (
            navigator.userLanguage || navigator.language
        ).replace(
            '-', '_'
        )
    ).toLowerCase()
).split('_');

希望它能帮助到别人

没有合适的方法来获得该设置，至少不是独立于浏览器的设置。

但是服务器有这个信息，因为它是HTTP请求头的一部分(Accept-Language字段，参见http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.4)

所以唯一可靠的方法是从服务器获取答案。你需要一些在服务器上运行的东西(比如。asp， .jsp， .php, CGI)，这个“东西”可以返回这些信息。 好的例子如下:http://www.developershome.com/wap/detection/detection.asp?page=readHeader

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
