MDN Reference

closed: boolean

The Window.closed read-only property indicates whether the referenced window is closed or not.

MDN Reference

cookieStore: CookieStore

The cookieStore read-only property of the Window interface returns a reference to the CookieStore object for the current document context. This is an entry point for the Cookie Store API.

MDN Reference

crossOriginIsolated: boolean

MDN Reference

crypto: Crypto

MDN Reference

customElements: CustomElementRegistry

The customElements read-only property of the Window interface returns a reference to the CustomElementRegistry object, which can be used to register new custom elements and get information about previously registered custom elements.

MDN Reference

devicePixelRatio: number

The devicePixelRatio of Window interface returns the ratio of the resolution in physical pixels to the resolution in CSS pixels for the current display device.

MDN Reference

document: Document

window.document returns a reference to the document contained in the window.

MDN Reference

event: Event

The read-only Window property event returns the Event which is currently being handled by the site's code. Outside the context of an event handler, the value is always undefined.

MDN Reference

external: External

The external property of the Window API returns an instance of the External interface, which was intended to contain functions related to adding external search providers to the browser. However, this is now deprecated, and the contained methods are now dummy functions that do nothing as per spec.

MDN Reference

frameElement: Element

The Window.frameElement property returns the element (such as <iframe> or <object>) in which the window is embedded.

MDN Reference

frames: Window

Returns the window itself, which is an array-like object, listing the direct sub-frames of the current window.

MDN Reference

history: History

The Window.history read-only property returns a reference to the History object, which provides an interface for manipulating the browser session history (pages visited in the tab or frame that the current page is loaded in).

MDN Reference

indexedDB: IDBFactory

MDN Reference

innerHeight: number

The read-only innerHeight property of the Window interface returns the interior height of the window in pixels, including the height of the horizontal scroll bar, if present.

MDN Reference

innerWidth: number

The read-only Window property innerWidth returns the interior width of the window in pixels (that is, the width of the window's layout viewport). That includes the width of the vertical scroll bar, if one is present.

MDN Reference

isSecureContext: boolean

MDN Reference

length: number

Returns the number of frames (either <frame> or <iframe> elements) in the window.

MDN Reference

localStorage: Storage

MDN Reference

locationbar: BarProp

Returns the locationbar object.

MDN Reference

menubar: BarProp

Returns the menubar object.

MDN Reference

name: string

The Window.name property gets/sets the name of the window's browsing context.

MDN Reference

navigation: Navigation

The navigation read-only property of the Window interface returns the current window's associated Navigation object.

MDN Reference

navigator: Navigator

The Window.navigator read-only property returns a reference to the Navigator object, which has methods and properties about the application running the script.

MDN Reference

opener: any

The Window interface's opener property returns a reference to the window that opened the window, either with open(), or by navigating a link with a target attribute.

MDN Reference

orientation: number

Returns the orientation in degrees (in 90-degree increments) of the viewport relative to the device's natural orientation.

MDN Reference

origin: string

MDN Reference

originAgentCluster: boolean

The originAgentCluster read-only property of the Window interface returns true if this window belongs to an origin-keyed agent cluster: this means that the operating system has provided dedicated resources (for example an operating system process) to this window's origin that are not shared with windows from other origins.

MDN Reference

outerHeight: number

The Window.outerHeight read-only property returns the height in pixels of the whole browser window, including any sidebar, window chrome, and window-resizing borders/handles.

MDN Reference

outerWidth: number

Window.outerWidth read-only property returns the width of the outside of the browser window. It represents the width of the whole browser window including sidebar (if expanded), window chrome and window resizing borders/handles.

MDN Reference

pageXOffset: number

MDN Reference

pageYOffset: number

MDN Reference

parent: Window

The Window.parent property is a reference to the parent of the current window or subframe.

MDN Reference

performance: Performance

MDN Reference

personalbar: BarProp

Returns the personalbar object.

MDN Reference

scheduler: Scheduler

MDN Reference

screen: Screen

The Window property screen returns a reference to the screen object associated with the window. The screen object, implementing the Screen interface, is a special object for inspecting properties of the screen on which the current window is being rendered.

MDN Reference

screenLeft: number

The Window.screenLeft read-only property returns the horizontal distance, in CSS pixels, from the left border of the user's browser viewport to the left side of the screen.

MDN Reference

screenTop: number

The Window.screenTop read-only property returns the vertical distance, in CSS pixels, from the top border of the user's browser viewport to the top side of the screen.

MDN Reference

scrollbars: BarProp

Returns the scrollbars object.

MDN Reference

scrollX: number

The read-only scrollX property of the Window interface returns the number of pixels by which the document is currently scrolled horizontally. This value is subpixel precise in modern browsers, meaning that it isn't necessarily a whole number. You can get the number of pixels the document is scrolled vertically from the scrollY property.

MDN Reference

scrollY: number

The read-only scrollY property of the Window interface returns the number of pixels by which the document is currently scrolled vertically. This value is subpixel precise in modern browsers, meaning that it isn't necessarily a whole number. You can get the number of pixels the document is scrolled horizontally from the scrollX property.

MDN Reference

self: Window & typeof globalThis

The Window.self read-only property returns the window itself, as a WindowProxy. It can be used with dot notation on a window object (that is, window.self) or standalone (self). The advantage of the standalone notation is that a similar notation exists for non-window contexts, such as in Web Workers. By using self, you can refer to the global scope in a way that will work not only in a window context (self will resolve to window.self) but also in a worker context (self will then resolve to WorkerGlobalScope.self).

MDN Reference

sessionStorage: Storage

MDN Reference

speechSynthesis: SpeechSynthesis

Returns the statusbar object.

MDN Reference

toolbar: BarProp

Returns the toolbar object.

MDN Reference

top: Window

Returns a reference to the **top**most window in the window hierarchy.
