The Node.nodeValue property returns or sets the value of the current node.
Syntax
value = node.nodeValue;
value is a string containing the value of the current node, if any.
Notes
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:
| Attr | value of attribute |
|---|---|
| CDATASection | content of the CDATA Section |
| Comment | content of the comment |
| Document | null |
| DocumentFragment | null |
| DocumentType | null |
| Element | null |
| NamedNodeMap | null |
| EntityReference | null |
| Notation | 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.
