The nodeValue property of the Node interface returns or sets the value of the current node.


str = node.nodeValue;
node.nodeValue = str;


str is a string containing the value of the current node, if any. For the document itself, nodeValue returns null. For text, comment, and CDATA nodes, nodeValue returns the content of the node. For attribute nodes, the value of the attribute is returned.

The following table shows the return values for different elements:

Node Value of nodeValue
CDATASection Content of the CDATA section
Comment Content of the comment
Document null
DocumentFragment null
DocumentType null
Element null
NamedNodeMap null
ProcessingInstruction Entire content excluding the target
Text Content of the text node

When nodeValue is defined to be null, setting it has no effect.
