Range.extractContents() 方法移动了Range 中的内容从文档树到DocumentFragment（文档片段对象）。
使用DOM事件添加的事件侦听器在提取期间不会保留。 HTML属性事件将按Node.cloneNode()方法的原样保留或复制。 HTML id属性也会被克隆，如果提取了部分选定的节点并将其附加到文档中，则可能导致无效的文档。
克隆了部分选定的节点，以包括使文档片段有效所需的父标记。
Syntax
documentFragment = range.extractContents();
Example
var range = document.createRange();
range.selectNode(document.getElementsByTagName("div").item(0));
var documentFragment = range.extractContents();
document.body.appendChild(documentFragment);
