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:(

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+。

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>
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"'
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
如果您不想依赖外部服务器，并且您有自己的服务器，您可以使用一个简单的PHP脚本来实现与@DanSingerman answer相同的行为。
languageDetector.php:
<?php
$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);
echo json_encode($lang);
?>
只需从jQuery脚本中更改这几行:
url: "languageDetector.php",
dataType: 'json',
success: function(language) {
nowDoSomethingWithIt(language);
}
我也遇到了同样的问题，于是我编写了以下前端专用库，它为多种浏览器打包了代码。代码并不多，但不用在多个网站上复制和粘贴相同的代码。
Get it: acceptedlanguages.js
使用它:
<script src="acceptedlanguages.js"></script>
<script type="text/javascript">
console.log('Accepted Languages: ' + acceptedlanguages.accepted);
</script>
它总是返回一个数组，按用户偏好排序。在Safari和IE中，数组总是单长度的。在FF和Chrome中，它可能不止一种语言。
