<p><span class="seoSummary">Das <code>window</code> Objekt repräsentiert ein Fenster (Window), das ein DOM Dokument enthält. Das <code>document</code> Attribut zeigt auf das <a href="/en-US/docs/DOM/document">DOM document</a>, das im Fenster geladen ist.</span> Für ein gegebenes Dokument kann man über das {{Domxref("document.defaultView")}} Attribut das Fenster abrufen.</p>

<p>Dieser Abschnitt bietet eine kurze Referenz für alle Methoden, Attribute und Events, die über das <code>window</code> Objekt zur Verfügung stehen. Das <code>window</code> Objekt implementiert die <code>Window</code> Schnitstelle, die wiederrum von der <code><a href="http://www.w3.org/TR/DOM-Level-2-Views/views.html#Views-AbstractView">AbstractView</a></code> Schnittstelle erbt. Einige zusätzliche globale Funktionen, <em>Namespace</em> Objekte, Schnittstellen und Konstruktoren, die nicht typischerweise mit dem <code>Window</code> in Verbindung gebracht werden, aber durch dieses verfügbar sind, werden in der <a href="/en-US/docs/JavaScript/Reference">JavaScript Reference</a> und <a href="/en-US/docs/DOM/DOM_Reference" title="/en-US/docs/DOM/DOM_Reference">DOM Reference</a> aufgelistet.</p>

<p>In einem "getabten" Browser wie Firefox enthält jeder Tab sein eigenes Window-Objekt (und im Falle von Extensions ist das Browser-Fenster selbst ein eigenständiges Fenster – siehe auch "<a href="/en-US/docs/Working_with_windows_in_chrome_code#Content_windows">Working with windows in chrome code</a>". Das heisst also, dass das Window-Objekt nicht zwischen Tabs desselben Fensters geteilt wird. Einige Methoden, zum Beispiel {{Domxref("window.resizeTo")}} und {{Domxref("window.resizeBy")}} beziehen sich auf das "ganze" Fenster, und nicht auf den Tab, dem das Window-Objekt gehört. Grundsätzlich lässt sich sagen, das alles, was man nicht sinnvollerweise einem Tab zuordnen kann, sich stattdessen auf das Window bezieht.</p>
