CDATA_SECTION_NODE: number

node is a CDATASection node.

COMMENT_NODE: number

node is a Comment node.

Readonly DOCUMENT_FRAGMENT_NODE

node is a document.

Readonly DOCUMENT_POSITION_CONTAINED_BY

DOCUMENT_POSITION_CONTAINED_BY: number

Set when other is a descendant of node.

Readonly DOCUMENT_POSITION_CONTAINS

DOCUMENT_POSITION_CONTAINS: number

Set when other is an ancestor of node.

Readonly DOCUMENT_POSITION_DISCONNECTED

DOCUMENT_POSITION_DISCONNECTED: number

Set when node and other are not in the same tree.

Readonly DOCUMENT_POSITION_FOLLOWING

DOCUMENT_POSITION_FOLLOWING: number

Set when other is following node.

Readonly DOCUMENT_POSITION_IMPLEMENTATION_SPECIFIC

DOCUMENT_POSITION_IMPLEMENTATION_SPECIFIC: number

Readonly DOCUMENT_POSITION_PRECEDING

node is an element.

Readonly ENTITY_NODE

Readonly NOTATION_NODE

NOTATION_NODE: number

Readonly PROCESSING_INSTRUCTION_NODE

PROCESSING_INSTRUCTION_NODE: number

Readonly TEXT_NODE

TEXT_NODE: number

Readonly activeElement

activeElement: null | internal.Element

Returns the deepest element in the document through which or to which key events are being routed. This is, roughly speaking, the focused element in the document.

For the purposes of this API, when a child browsing context is focused, its container is focused in the parent browsing context. For example, if the user moves the focus to a text control in an iframe, the iframe is the element returned by the activeElement API in the iframe's node document.

Similarly, when the focused element is in a different node tree than documentOrShadowRoot, the element returned will be the host that's located in the same node tree as documentOrShadowRoot if documentOrShadowRoot is a shadow-including inclusive ancestor of the focused element, and null if not.
