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:(

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"'

对于正在寻找Java服务器解决方案的人
这里是RestEasy
@GET
@Path("/preference-language")
@Consumes({"application/json", "application/xml"})
@Produces({"application/json", "application/xml"})
public Response getUserLanguagePreference(@Context HttpHeaders headers) {
return Response.status(200)
.entity(headers.getAcceptableLanguages().get(0))
.build();
}
Dan Singerman的回答有一个问题，因为jQuery ajax的异步特性，获取的头文件必须立即使用。但是，使用他的谷歌应用服务器，我编写了以下内容，以便将报头设置为初始设置的一部分，并可以在以后使用。
<html>
<head>
<script>
var bLocale='raw'; // can be used at any other place
function processHeaders(headers){
bLocale=headers['Accept-Language'];
comma=bLocale.indexOf(',');
if(comma>0) bLocale=bLocale.substring(0, comma);
}
</script>
<script src="jquery-1.11.0.js"></script>
<script type="application/javascript" src="http://ajaxhttpheaders.appspot.com?callback=processHeaders"></script>
</head>
<body>
<h1 id="bLocale">Should be the browser locale here</h1>
</body>
<script>
$("#bLocale").text(bLocale);
</script>
</html>
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+。
我一直在使用Hamid的答案一段时间，但在语言数组像["en"， "en- gb "， "en- us "， "fr- fr"， "fr"， "en- za "]的情况下，它将返回"en"，当"en- gb "将是一个更好的匹配。
我的更新(下面)将返回第一个长格式的代码，例如。"en-GB"，否则将返回第一个短代码，例如。"en"，否则返回null。
function getFirstBrowserLanguage() { var nav = window.navigator, browserLanguagePropertyKeys = ['language', 'browserLanguage', 'systemLanguage', 'userLanguage'], i, language, len, shortLanguage = null; // support for HTML 5.1 "navigator.languages" if (Array.isArray(nav.languages)) { for (i = 0; i < nav.languages.length; i++) { language = nav.languages[i]; len = language.length; if (!shortLanguage && len) { shortLanguage = language; } if (language && len>2) { return language; } } } // support for other well known properties in browsers for (i = 0; i < browserLanguagePropertyKeys.length; i++) { language = nav[browserLanguagePropertyKeys[i]]; //skip this loop iteration if property is null/undefined. IE11 fix. if (language == null) { continue; } len = language.length; if (!shortLanguage && len) { shortLanguage = language; } if (language && len > 2) { return language; } } return shortLanguage; } console.log(getFirstBrowserLanguage());
更新:当某些属性未定义时，IE11出现错误。增加了跳过这些属性的检查。
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
