<h2 id="语言区域识别和判定">语言区域识别和判定</h2>
<p>国际化的构造函数和其他构造函数的几个语言敏感的方法（可参考下方的<a href="#See_also">参见</a>）一样，使用同样的模式来识别语言区域和确定使用哪一种语言格式：他们都接收 <code>locales</code> 和 <code>options</code> 参数，使用 <code>options.localeMatcher</code> 属性指定的一个算法来对比应用请求的和支持的语言区域，来确定使用哪一个语言区域。</p>
<h3 id="locales_参数"><code>locales</code> 参数</h3>
<p><code>locales</code> 参数必须是一个 <a class="external" href="http://tools.ietf.org/html/rfc5646" rel="noopener">BCP 47 语言标记</a>的字符串，或者是一个包括多个语言标记的数组。如果 <code>locales</code> 参数未提供或者是 undefined，便会使用运行时默认的 locale。</p>
<p>一个 BCP 47 语言标记代表了一种语言或者区域（两者没有很大的区别）。在其最常见的格式中，它以这样的顺序囊括了这些内容：语言代码，脚本代码，和国家代码，全部由连字符分隔开。例如：</p>
<ul>
<li><code>"hi"</code>：印地语 (primary language)。</li>
<li><code>"de-AT"</code>：<code>在奥地利使用的德语 (primary language with country code)。</code></li>
<li><code>"zh-Hans-CN"</code>：在中国使用的简体中文 (primary language with script and country codes)。</li>
</ul>
<p>在 BCP 47 中表示语言，脚本，国家（区域）和变体（少用）的语言子标记含义可以在<a class="external" href="http://www.iana.org/assignments/language-subtag-registry/language-subtag-registry" rel="noopener"> IANA 语言子标记注册</a>中找到。</p>
<p>BCP 47 也支持扩展，其中一个和 JavaScript 国际化方法相关的是："u"（Unicode）扩展。它可以用于请求一个自定义区域特定行为的 <a href="Reference/Global_Objects/Collator" title="Intl.Collator 是用于语言敏感字符串比较的 collators构造函数。"><code>Collator</code></a>，<a href="Reference/Global_Objects/NumberFormat" title="Intl.NumberFormat是对语言敏感的格式化数字类的构造器类"><code>NumberFormat</code></a>，或者 <a href="Reference/Global_Objects/DateTimeFormat" title="交互示例的源代码存储在 GitHub 资源库。如果你愿意分布交互示例，请复制https://github.com/mdn/interactive-examples，并向我们发送一个pull请求。"><code>DateTimeFormat</code></a> 对象。例如：</p>
<ul>
<li><code>"de-DE-u-co-phonebk"</code>：使用德语的电话簿排序变体，这会把元音变音扩展成字符对：ä → ae, ö → oe, ü → ue。</li>
<li><code>"th-TH-u-nu-thai"</code>：在数字格式中使用泰语的数值表示（๐, ๑, ๒, ๓, ๔, ๕, ๖, ๗, ๘, ๙）</li>
<li><code>"ja-JP-u-ca-japanese"：在日期和时间格式化中使用日本的日历表示方式，所以 2013 会表示为平成 25。</code></li>
<li><code>"en-GB-u-ca-islamic"</code>: use British English with the Islamic (Hijri) calendar, where the Gregorian date 14 October, 2017 is the Hijri date 24 Muharram, 1439.</li>
</ul>
<h3 id="语言区域判定">语言区域判定</h3>
<p><code>locales</code> 参数，在除去所有的 Unicode 扩展之后，会被转化成来自应用的优先请求。运行时拿它和可用的语言区域做对比然后选择出最合适的一个。有两种匹配算法：“查找” 匹配遵循 <a class="external" href="http://tools.ietf.org/html/rfc5646" rel="noopener">BCP 47</a> 中指定的查找算法；“最佳命中” 匹配器会让运行时至少提供一个语言区域，但合适请求的结果可能会比查找算法的要多。如果应用没有提供一个 locales 参数，或者运行时没有一个匹配请求的语言区域，那么会使用运行时默认的语言区域。匹配器可以使用 <code>options</code> 参数的一个属性来进行选择（见下方）。</p>
<p>如果选中的语言标记有一个 Unicode 扩展子字符串，这个扩展会用于自定义构造对象或者方法的行为。每一个构造函数或者方法仅支持 Unicode 扩展定义的 key 的一个子集，和依赖于语言标记的支持的值。例如，<code>“co”</code>这个 key（collation）只在 <a href="Reference/Global_Objects/Collator" title="Intl.Collator 是用于语言敏感字符串比较的 collators构造函数。"><code>Collator</code></a> 中支持，它的值 “phonebk” 只在德语中支持。</p>
<h3 id="options_参数"><code>options</code> 参数</h3>
<p><code>options</code> 参数必须是一个对象，其属性值在不同的构造函数和方法中会有所变化。如果 <code>options</code> 参数未提供或者为 undefined，所有的属性值则使用默认的。</p>
<p>所有语言敏感的构造函数和方法都支持的一个属性是：<code>localeMatcher</code> 属性，它的值必须是字符串 “lookup” 或者 “best fit”，用于选择上边描述的语言区域匹配算法。</p>
