Node
Node is an interface from which a number of DOM API object types inherit. It allows those types to be treated similarly; for example, inheriting the same set of methods, or being tested in the same way.

nodeName: StringReturns a DOMString 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.
baseURI: StringReturns a DOMString representing the base URL. The concept of base URL changes from one language to another; in HTML, it corresponds to the protocol, the domain name and the directory structure, that is all until the last '/'.
isConnected: BoolReturns a 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.
ownerDocument: HTMLDocumentReturns the Document that this node belongs to. If the node is itself a document, returns null.
parentNode: NodeReturns 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.
parentElement: ElementReturns 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.
childNodes: NodeListReturns 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.
firstChild: NodeReturns a Node representing the first direct child node of the node, or null if the node has no child.
lastChild: NodeReturns a Node representing the last direct child node of the node, or null if the node has no child.
previousSibling: NodeReturns a Node representing the previous node in the tree, or null if there isn't such node.
nextSibling: NodeReturns a Node representing the next node in the tree, or null if there isn't such node.
nodeValue: StringReturns / Sets the value of the current node
textContent: StringReturns / Sets the textual content of an element and all its descendants.
getRootNode(?options: Null<GetRootNodeOptions>): NodeReturns the context object's root which optionally includes the shadow root if it is available.
| Name | Type | Default |
|---|---|---|
options |
Null<GetRootNodeOptions> | (optional) |
| Returns |
|---|
| Node |
hasChildNodes(): BoolReturns a Boolean indicating if the element has any child nodes, or not.
| Returns |
|---|
| Bool |
Inserts a Node before the reference node as a child of a specified parent node.
| Name | Type |
|---|---|
node |
Node |
child |
Node |
| Returns |
|---|
| Node |
Adds the specified childNode argument as the last child to the current node.
If the argument referenced an existing node on the DOM tree, the node will be detached from its current position and attached at the new position.
| Name | Type |
|---|---|
node |
Node |
| Returns |
|---|
| Node |
Replaces one child Node of the current one with the second one given in parameter.
| Name | Type |
|---|---|
node |
Node |
child |
Node |
| Returns |
|---|
| Node |
Removes a child node from the current element, which must be a child of the current node.
| Name | Type |
|---|---|
child |
Node |
| Returns |
|---|
| Node |
normalize(): VoidClean up all the text nodes under this element (merge adjacent, remove empty).
Clone a Node, and optionally, all of its contents. By default, it clones the content of the node.
| Name | Type | Default |
|---|---|---|
deep |
Bool | false |
| Returns |
|---|
| Node |
Returns a Boolean value indicating whether or not the two nodes are the same (that is, they reference the same object).
| Name | Type |
|---|---|
node |
Node |
| Returns |
|---|
| Bool |
Returns a Boolean which indicates whether or not two nodes are of the same type and all their defining data points match.
| Name | Type |
|---|---|
node |
Node |
| Returns |
|---|
| Bool |
Compares the position of the current node against another node in any other document.
| Name | Type |
|---|---|
other |
Node |
| Returns |
|---|
| Int |
Returns a Boolean value indicating whether a node is a descendant of a given node or not.
| Name | Type |
|---|---|
other |
Node |
| Returns |
|---|
| Bool |
Returns a DOMString containing the prefix for a given namespace URI, if present, and null if not. When multiple prefixes are possible, the result is implementation-dependent.
| Name | Type |
|---|---|
namespace |
String |
| Returns |
|---|
| String |
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.
| Name | Type |
|---|---|
prefix |
String |
| Returns |
|---|
| String |
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.
