cloneNode (method )

Owning interface and usage:

Node.cloneNode(deep)

Member of these other interfaces:

Attr, CDATASection, CharacterData, Comment, Document, DocumentFragment, DocumentType, Element, Entity, EntityReference, Notation, ProcessingInstruction, Text

Description:

Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent (parentNode is null).

Parameters:

Boolean deep

If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element).

Returns:

Node - The duplicate node.

Exceptions:

none

Note:

Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child Text node. Cloning an Attribute directly, as opposed to be cloned as part of an Element cloning operation, returns a specified attribute (specified is true). Cloning any other type of node simply returns a copy of this node.
Note that cloning an immutable subtree results in a mutable copy, but the children of an EntityReference clone are readonly. In addition, clones of unspecified Attr nodes are specified. And, cloning Document, DocumentType, Entity, and Notation nodes is implementation dependent.

Example:

Source:	<div id="doc"> <div> Text in the first DIV. </div> <div id="DDD" class="secondClass"> Some text in the second DIV. </div> <div class="thirdClass"> Some text and <span id="SSS">element</span> in the third DIV. </div> <div class="fourthClass"> We can try <i>another elements</i>. It will be much more <b>interesting</b>. </div> <div> Text in the last DIV. </div> </div>

Source:

   <div id="doc">
     <div>
       Text in the first DIV.
     </div>
     <div id="DDD" class="secondClass">
       Some text in the second DIV.
     </div>
     <div class="thirdClass">
       Some text and <span id="SSS">element</span> in the third DIV.
     </div>
     <div class="fourthClass">
       We can try <i>another elements</i>.
       It will be much more <b>interesting</b>.
     </div>
     <div>
       Text in the last DIV.
     </div>
   </div>

JavaScript:	var main = document.getElementById('doc'); var elem = main.childNodes[3]; var returns = elem.cloneNode(true); var output = returns.firstChild.nodeValue;

Output:

desired		your browser
white-spaces preserved by default	Some text in the second DIV.
white-spaces not-preserved by default	We can try
