Properties
ApplicationCache	applicationCache
boolean	closed The closed attribute on Window objects must return true if the Window object's browsing context has been discarded, and false otherwise.
Document	document The document IDL attribute must return the Window object's newest Document object.
External	external The external attribute of the Window interface must return an instance of the External interface. The same object must be returned each time.
Element?	frameElement

History	history The history attribute of the Window interface must return the object implementing the History interface for that Window object's newest Document.
IDBFactory	indexedDB This attribute provides applications a mechanism for accessing capabilities of indexed databases.
unsigned long	length The length IDL attribute on the Window interface must return the number of child browsing contexts that are nested through elements that are in the Document that is the active document of that Window object, if that Window's browsing context shares the same event loop as the responsible document specified by the entry settings object accessing the IDL attribute; otherwise, it must return zero.

WindowProxy?	opener The opener IDL attribute on the Window object, on getting, must return the WindowProxy object of the browsing context from which the current browsing context was created (its opener browsing context), if there is one, if it is still available, and if the current browsing context has not disowned its opener; otherwise, it must return null.
WindowProxy	parent The parent IDL attribute on the Window object of a Document in a browsing context b must return the WindowProxy object of the parent browsing context, if there is one (i.e. if b is a child browsing context), or the WindowProxy object of the browsing context b itself, otherwise (i.e.
BarProp	personalbar The personalbar attribute must return the personal bar BarProp object.
BarProp	scrollbars The scrollbars attribute must return the scrollbar BarProp object.
WindowProxy	self The window, frames, and self IDL attributes must all return the Window object's browsing context's WindowProxy object.
Storage	sessionStorage The sessionStorage attribute represents the set of storage areas specific to the current top-level browsing context.
DOMString	status For historical reasons, the status attribute on the Window object must, on getting, return the last string it was set to, and on setting, must set itself to the new value. When the Window object is created, the attribute must be set to the empty string.
BarProp	statusbar The statusbar attribute must return the status bar BarProp object.
BarProp	toolbar The toolbar attribute must return the toolbar BarProp object.
WindowProxy	top The top IDL attribute on the Window object of a Document in a browsing context b must return the WindowProxy object of its top-level browsing context (which would be its own WindowProxy object if it was a top-level browsing context itself), if it has one, or its own WindowProxy object otherwise (e.g.
WindowProxy	window The window, frames, and self IDL attributes must all return the Window object's browsing context's WindowProxy object.

Operations
void	alert(optional DOMString message)
DOMString	atob(DOMString atob)
void	blur()
DOMString	btoa(DOMString btoa) The btoa() method must throw an InvalidCharacterError exception if the method's first argument contains any character whose code point is greater than U+00FF. Otherwise, the user agent must convert that argument to a sequence of octets whose nth octet is the eight-bit representation of the code point of the nth character of the argument, and then must apply the base64 algorithm to that sequence of octets, and return the result.
void	cancelAnimationFrame(long handle) The cancelAnimationFrame method is used to cancel a previously made request to schedule an animation frame update. When cancelAnimationFrame(handle) is called, the user agent MUST set the cancelled flag to true for the callback registered on this Document whose handle is handle.
void	clearInterval(optional long handle) The clearTimeout() and clearInterval() methods must clear the entry identified as handle from the list of active timers of the WindowTimers object on which the method was invoked, if any, where handle is the argument passed to the method. (If handle does not identify an entry in the list of active timers of the WindowTimers object on which the method was invoked, the method does nothing.)
void	clearTimeout(optional long handle) The clearTimeout() and clearInterval() methods must clear the entry identified as handle from the list of active timers of the WindowTimers object on which the method was invoked, if any, where handle is the argument passed to the method. (If handle does not identify an entry in the list of active timers of the WindowTimers object on which the method was invoked, the method does nothing.)
void	close()
boolean	confirm(optional DOMString message)
Promise	createImageBitmap(ImageBitmapSource image, optional long sx, long sy, long sw, long sh) An ImageBitmap object can be obtained from a variety of different objects, using the createImageBitmap() method.
void	focus()
CSSStyleDeclaration	getComputedStyle(Element elt, optional DOMString pseudoElt)
WindowProxy	getter(any index_name) To determine the value of an indexed property index of a Window object, the user agent must return the WindowProxy object of the indexth child browsing context of the Document that is nested through an element that is in the Document, sorted in the order that the elements nesting those browsing contexts were most recently inserted into the Document, the WindowProxy object of the most recently inserted browsing context container's nested browsing context being last.
WindowProxy	open(optional DOMString url, optional DOMString target, optional DOMString features, optional boolean replace) The open() method on Window objects provides a mechanism for navigating an existing browsing context or opening and navigating an auxiliary browsing context.
void	postMessage(any message, DOMString targetOrigin, optional sequence<Transferable> transfer)
void	print() When the print() method is invoked, if the Document is ready for post-load tasks, then the user agent must synchronously run the printing steps. Otherwise, the user agent must only set the print when loaded flag on the Document.
DOMString?	prompt(optional DOMString message, optional DOMString default)
long	requestAnimationFrame(FrameRequestCallback callback) The requestAnimationFrame method is used to signal to the user agent that a script-based animation needs to be resampled. When requestAnimationFrame(callback) is called, the user agent MUST schedule a script-based animation resampling by appending to the end of the animation frame request callback list an entry whose handle is a user-agent-defined integer greater than zero that uniquely identifies the entry in the list and whose callback is callback.
long	setInterval(any handler, optional long timeout, any arguments...) The setInterval() method must return the value returned by the timer initialization steps, passing them the method's arguments, the object on which the method for which the algorithm is running is implemented (a Window or WorkerGlobalScope object) as the method context, and the repeat flag set to true.
long	setTimeout(any handler, optional long timeout, any arguments...) The setTimeout() method must return the value returned by the timer initialization steps, passing them the method's arguments, the object on which the method for which the algorithm is running is implemented (a Window or WorkerGlobalScope object) as the method context, and the repeat flag set to false.
any	showModalDialog(DOMString url, optional any argument)
void	stop() The stop() method on Window objects should, if there is an existing attempt to navigate the browsing context and that attempt is not currently running the unload a document algorithm, cancel that navigation; then, it must abort the active document of the browsing context of the Window object on which it was invoked.
