## Description
|
||
<section id="description">除了移动元素，您还可以将它们从一个地方复制到另一个地方。 jQuery有一个名为<code>clone()</code>的函数，它可以复制一个元素。例如，如果我们想将<code>target2</code>从我们的<code>left-well</code>复制到<code>right-well</code> ，我们将使用： <code>$("#target2").clone().appendTo("#right-well");</code>您是否注意到这涉及将两个jQuery函数粘在一起？这称为<code>function chaining</code> ，它是使用jQuery完成任务的便捷方式。克隆你的<code>target5</code>元素并将其附加到你的<code>left-well</code> 。 </section>
