<p><strong>注意:</strong>

如果您使用一个自定义的jQuery绑定一个<em>没有效果模块</em>， <code>:animated</code>选择器会抛出一个错误。</p>

<h3>Additional Notes:（其他注意事项：）</h3>
|
||
<div class="longdesc"><ul><li>
|
||
因为<code>:animated</code> 是一个 jQuery 延伸出来的选择器，并不是的CSS规范的一部分，使用<code>:animated</code> 查询不能充分利用原生DOM提供的<code>querySelectorAll()</code> 方法来提高性能。为了当使用<code>:animated</code> 的时候在现代浏览器上获得更佳的性能，首先使用纯CSS选择器选择元素，然后使用<a href="/filter"><code>.filter(":animated")</code></a>.
