<p><strong><code>Range.cloneContents()</code></strong> 返回一个 {{ domxref("DocumentFragment") }}，它是 {{ domxref("Range") }} 中所有的 {{ domxref("Node") }} 对象的副本。</p>

<p>使用" DOM 事件"添加的“事件侦听器”在克隆过程中不会被复制。 HTML属性事件与“DOM Core cloneNode”方法一样被复制。“HTML id属性”也将被克隆，这可能导致通过克隆导致无效的文档。</p>

<p>Partially selected nodes include the parent tags necessary to make the document fragment valid.</p>
