Node is an interface from which various types of DOM API objects inherit, allowing those types to be treated similarly; for example, inheriting the same set of methods, or being testable in the same way.Node interface's methods and properties: Document, Element, Attr, CharacterData (which Text, Comment, and CDATASection inherit), ProcessingInstruction, DocumentFragment, DocumentType, Notation, Entity, EntityReferencenull in certain cases where the methods and properties are not relevant. They may throw an exception — for example when adding children to a node type for which no children can exist.Returns a string representing the base URL of the document containing the Node.
Promise<string>Returns a live NodeList containing all the children of this node. NodeList being live means that if the children of the Node change, the NodeList object is automatically updated.
SuperNodeListReturns a Node representing the first direct child node of the node, or null if the node has no child.
SuperNodeA boolean indicating whether or not the Node is connected (directly or indirectly) to the context object, e.g. the Document object in the case of the normal DOM, or the ShadowRoot in the case of a shadow DOM.
Promise<boolean>Returns a Node representing the last direct child node of the node, or null if the node has no child.
SuperNodeReturns a Node representing the next node in the tree, or null if there isn't such node.
SuperNodeReturns a string containing the name of the Node. The structure of the name will differ with the node type. E.g. An HTMLElement will contain the name of the corresponding tag, like 'audio' for an HTMLAudioElement, a Text node will have the '#text' string, or a Document node will have the '#document' string.
Promise<string>Returns an unsigned short representing the type of the node. Possible values are:
Name Value ELEMENT_NODE1ATTRIBUTE_NODE 2TEXT_NODE3CDATA_SECTION_NODE4ENTITY_REFERENCE_NODE 5ENTITY_NODE 6PROCESSING_INSTRUCTION_NODE7COMMENT_NODE8DOCUMENT_NODE9DOCUMENT_TYPE_NODE10DOCUMENT_FRAGMENT_NODE11NOTATION_NODE 12
Promise<number>Returns / Sets the value of the current node.
Promise<string>Returns the Document that this node belongs to. If the node is itself a document, returns null.
SuperDocumentReturns an Element that is the parent of this node. If the node has no parent, or if that parent is not an Element, this property returns null.
SuperElementReturns a Node that is the parent of this node. If there is no such node, like if this node is the top of the tree or if doesn't participate in a tree, this property returns null.
SuperNodeReturns a Node representing the previous node in the tree, or null if there isn't such node.
SuperNodeReturns / Sets the textual content of an element and all its descendants.
Promise<string>Compares the position of the current node against another node in any other document.
Node. The other Node with which to compare the first node’s document position.Promise<number>Returns a boolean value indicating whether or not a node is a descendant of the calling node.
Node. Needs content.Promise<boolean>Returns the context object's root which optionally includes the shadow root if it is available.
GetRootNodeOptions. An object that sets options for getting the root node. The available options are: composed: A `boolean` that indicates whether the shadow root should be returned (false, the default), or a root node beyond shadow root (true).SuperNodeReturns a boolean indicating whether or not the element has any child nodes.
Promise<boolean>Accepts a namespace URI as an argument and returns a boolean with a value of true if the namespace is the default namespace on the given node or false if not.
string. namespaceURI is a string representing the namespace against which the element will be checked.Promise<boolean>Returns a boolean which indicates whether or not two nodes are of the same type and all their defining data points match.
Node. otherNode: The Node to compare equality with.Promise<boolean>Returns a boolean value indicating whether or not the two nodes are the same (that is, they reference the same object).
Node. otherNode The Node to test against.Promise<boolean>Accepts a prefix and returns the namespace URI associated with it on the given node if found (and null if not). Supplying null for the prefix will return the default namespace.
string. The prefix to look for. If this parameter is null, the method will return the default namespace URI, if any.Promise<string>Returns a string containing the prefix for a given namespace URI, if present, and null if not. When multiple prefixes are possible, the result is implementation-dependent.
string. Needs content.Promise<string>Clean up all the text nodes under this element (merge adjacent, remove empty).
