<p><code>:lang</code>选择器,匹配有一个语言值等于所提供的语言代码，或以提供的语言代码开始，后面马上跟一个“ - ”的元素。例如，选择器<code>$("div:lang(en)")</code>将匹配<code><div lang="en"></code> and <code><div lang="en-us"></code>（和他们的后代<code><div></code>），但不包括<code><div lang="fr"></code></p>
|
||
<p>对于HTML元素，语言值由<code>lang</code>属性决定，也可能由来自<code>meta</code>元素或HTTP头信息决定。</p>
