<p><code><strong>toLocaleString()</strong></code> 方法返回这个数字在特定语言环境下的表示字符串。</p>
<p>新的 <code>locales</code> 和 <code>options</code> 参数让应用程序可以指定要进行格式转换的语言，并且定制函数的行为。在旧的实现中，会忽略 <code>locales</code> 和 <code>options</code> 参数，使用的语言环境和返回的字符串的形式完全取决于实现方式。</p>

<h3 id="返回值">返回值</h3>
<p>返回一个语言环境下的表示字符串。</p>
<h2 id="示例">示例</h2>
<h3 id="使用_toLocaleString">使用 <code>toLocaleString</code></h3>
<p>在没有指定区域的基本使用时，返回使用默认的语言环境和默认选项格式化的字符串。</p>
<pre><code class="language-javascript">var number = 3500;
console.log(number.toLocaleString()); // Displays "3,500" if in U.S. English locale
</code></pre>
<h3 id="检查_locales_和_options_参数的支持">检查 <code>locales</code> 和 <code>options</code> 参数的支持</h3>
<p><code>locales</code> 和 <code>options</code> 参数目前还不是所有浏览器都支持的。在 ES5.1 和更新的实现中检查支持情况，可以依靠使用非法参数时规定抛出的 <a href="Reference/Global_Objects/RangeError" title="RangeError对象标明一个错误，当一个值不在其所允许的范围或者集合中。"><code>RangeError</code></a> 异常：</p>
<pre><code class="language-javascript">function toLocaleStringSupportsLocales() {
var number = 0;
try {
number.toLocaleString('i');
} catch (e) {
return e​.name === 'RangeError';
}
return false;
}
</code></pre>
<p>早于 ES5.1 的实现中，如果带参数调用 <code>toLocaleString</code> 并不会抛出范围异常。</p>
<p>在所有宿主环境下，包括那些支持比 ed 5.1 还早的 ECMA-262 的环境，都能有效检测的方法是直接检测 ECMA-402 中的其它特性，它指定 <code>Number.prototype.toLocaleString</code> 需要支持地区选项：</p>
<pre><code class="language-javascript">function toLocaleStringSupportsOptions() {
return !!(typeof Intl == 'object' &amp;&amp; Intl &amp;&amp; typeof Intl.NumberFormat == 'function');
}
</code></pre>
<p>它测试全局的 <code>Intl</code> 对象，检测它不是 <code>null</code> 并且有 <code>NumberFormat</code> 的方法。</p>
<h3 id="使用_locales">使用 <code>locales</code></h3>
<p>这个示例展示了不同地区数字格式的差异。为了设置你的应用程序界面下使用的语言格式，请确保使用 <code>locales</code> 参数指定了使用的语言（可能还有一些备用语言）：</p>
<pre><code class="language-javascript">var number = 123456.789;
// 德国使用逗号作为小数分隔符，分位周期为千位
console.log(number.toLocaleString('de-DE'));
// → 123.456,789
// 在大多数阿拉伯语国家使用<a class="external" href="https://en.wikipedia.org/wiki/Eastern_Arabic_numerals" rel="noopener">阿拉伯语</a>数字
console.log(number.toLocaleString('ar-EG'));
// → ١٢٣٤٥٦٫٧٨٩
// 印度使用千位/拉克（十万）/克若尔（千万）分隔
console.log(number.toLocaleString('en-IN'));
// → 1,23,456.789
// nu 扩展字段要求编号系统，e.g. 中文十进制
console.log(number.toLocaleString('zh-Hans-CN-u-nu-hanidec'));
// → 一二三,四五六.七八九
// 当请求不支持的语言时，例如巴厘语，加入一个备用语言，比如印尼语
console.log(number.toLocaleString(['ban', 'id']));
// → 123.456,789
</code></pre>
<h3 id="使用_options">使用 <code>options</code></h3>
<p>通过 <code>toLocaleString</code> 返回的结果可以通过 <code>options</code> 参数进行定制：</p>
<pre><code class="language-javascript">var number = 123456.789;
// 要求货币格式
console.log(number.toLocaleString('de-DE', { style: 'currency', currency: 'EUR' }));
// → 123.456,79 €
// 日元不使用小数位
console.log(number.toLocaleString('ja-JP', { style: 'currency', currency: 'JPY' }))
// → ￥123,457
// 限制三位有效数字
console.log(number.toLocaleString('en-IN', { maximumSignificantDigits: 3 }));
// → 1,23,000
</code></pre>
<h2 id="性能">性能</h2>
<p>当格式化大量数字时，最好建立一个 <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> 对象并且使用它提供的 <a href="Reference/Global_Objects/NumberFormat/format" title="Intl.NumberFormat.prototype.format 属性返回一个根据NumberFormat对象的语言环境和格式化选项，来格式化一个数字的getter函数。"><code>NumberFormat.format</code></a> 方法。</p>
