DOM Information

Inheritance Hierarchy

The Node does not inherit from any class or interface.


The Node object has these types of members:


The Node object has these methods.


Registers an event handler for the specified event type.


Sends an event to the current element.


Removes an event handler that the addEventListener method registered.



The Node interface is the primary datatype for the entire Document Object Model (DOM). It represents a single node in the document tree. While all objects implementing the Node interface expose methods for dealing with children, not all objects implementing the Node interface may have children. For example, text nodes may not have children, and adding children to such nodes results in a DOMException.

The attributes nodeName, nodeValue and attributes are included as a mechanism to get at node information without casting down to the specific derived interface. In cases where there is no obvious mapping of these attributes for a specific nodeType (i.e., nodeValue for an Element or attributes for a Comment), this returns null. Note that the specialized interfaces may contain additional and more convenient mechanisms to get and set the relevant information.
