Accessors

Methods

Properties

activeElement: null | 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.

MDN Reference

adoptedStyleSheets: CSSStyleSheet[]
alinkColor: string

Sets or gets the color of all active links in the document.

MDN Reference

all: HTMLAllCollection

Returns a reference to the collection of elements contained by the object.

MDN Reference

anchors: HTMLCollectionOf<HTMLAnchorElement>

Retrieves a collection of all a objects that have a name and/or id property. Objects in this collection are in HTML source order.

MDN Reference

Retrieves a collection of all applet objects in the document.

MDN Reference

ATTRIBUTE_NODE
baseURI: string

Returns node's node document's document base URL.

MDN Reference

bgColor: string

Deprecated. Sets or retrieves a value that indicates the background color behind the object.

MDN Reference

Specifies the beginning and end of the document body.

MDN Reference

CDATA_SECTION_NODE

node is a CDATASection node.

characterSet: string

Returns document's encoding.

MDN Reference

charset: string

Gets or sets the character set used to encode the object.

This is a legacy alias of characterSet.

MDN Reference

childElementCount: number
childNodes: NodeListOf<ChildNode>

Returns the children.

MDN Reference

children: HTMLCollection

Returns the child elements.

MDN Reference

COMMENT_NODE

node is a Comment node.

compatMode: string

Gets a value that indicates whether standards-compliant mode is switched on for the object.

MDN Reference

contentType: string

Returns document's content type.

MDN Reference

cookie: string

Returns the HTTP cookies that apply to the Document. If there are no cookies or cookies can't be applied to this resource, the empty string will be returned.

Can be set, to add a new cookie to the element's set of HTTP cookies.

If the contents are sandboxed into a unique origin (e.g. in an iframe with the sandbox attribute), a "SecurityError" DOMException will be thrown on getting and setting.

MDN Reference

currentScript: null | HTMLOrSVGScriptElement

Returns the script element, or the SVG script element, that is currently executing, as long as the element represents a classic script. In the case of reentrant script execution, returns the one that most recently started executing amongst those that have not yet finished executing.

Returns null if the Document is not currently executing a script or SVG script element (e.g., because the running script is an event handler, or a timeout), or if the currently executing script or SVG script element represents a module script.

MDN Reference

defaultView: null | Window & typeof globalThis

Returns the Window object of the active document.

MDN Reference

designMode: string

Sets or gets a value that indicates whether the document can be edited.

MDN Reference

dir: string

Sets or retrieves a value that indicates the reading order of the object.

MDN Reference

doctype: null | DocumentType

Gets an object representing the document type declaration associated with the current document.

MDN Reference

DOCUMENT_FRAGMENT_NODE

node is a DocumentFragment node.

DOCUMENT_NODE

DOCUMENT_POSITION_CONTAINED_BY

Set when other is a descendant of node.

DOCUMENT_POSITION_CONTAINS

Set when other is an ancestor of node.

DOCUMENT_POSITION_DISCONNECTED

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

DOCUMENT_POSITION_FOLLOWING

DOCUMENT_POSITION_IMPLEMENTATION_SPECIFIC
DOCUMENT_POSITION_PRECEDING

Set when other is preceding node.

Accessors

  • get location(): Location
  • Contains information about the current URL.

    MDN Reference

    Returns Location

  • set location(href): void
  • Parameters

    Returns void

Methods

  • Appends an event listener for events whose type attribute value is type. The callback argument sets the callback that will be invoked when the event is dispatched.

    The options argument sets listener-specific options. For compatibility this can be a boolean, in which case the method behaves exactly as if the value was specified as options's capture.

    When set to true, options's capture prevents callback from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE. When false (or not present), callback will not be invoked when event's eventPhase attribute value is CAPTURING_PHASE. Either way, callback will be invoked if event's eventPhase attribute value is AT_TARGET.

    When set to true, options's passive indicates that the callback will not cancel the event by invoking preventDefault(). This is used to enable performance optimizations described in § 2.8 Observing event listeners.

    When set to true, options's once indicates that the callback will only be invoked once after which the event listener will be removed.

    If an AbortSignal is passed for options's signal, then the event listener will be removed when signal is aborted.

    The event listener is appended to target's event listener list and is not appended if it has the same type, callback, and capture.
