{{APIRef}}

+ +

window 物件代表了一個包含 DOM 文件的視窗，其中的 document 屬性指向了視窗中載入的 {{domxref("Document")}} 物件。而使用 document 的 {{Domxref("Document.defaultView", "defaultView")}} 屬性，則可取得該 Document 物件所在的視窗 window 物件。

+ +

本節提供了 DOM window 物件的所有方法、屬性以及事件的說明。window 物件實作了 Window 介面，而 Window 介面則繼承自 AbstractView 介面。一些額外、與 window 物件沒有直接關係，但卻置於 window 物件中的全域函式、命名空間、物件、介面以及建構式，將會在 JavaScript 參考文件和文件物件模型（DOM）中說明。

+ +

在支援分頁的瀏覽器中（如 Firefox），每一個分頁標籤都擁有自己的 window 物件（如果你正在撰寫瀏覽器附加元件，瀏覽器視窗本身也是一個個別的 window－請參閱 Working with windows in chrome code），分頁不會於同一個瀏覽器視窗中共享 window 物件。但有部分的方法，如 {{Domxref("window.resizeTo()")}} 或 {{Domxref("window.resizeBy()")}} 會套用至整個視窗，而不只是該 window 物件所屬的分頁標籤。一般來說，若無法適當的應用於分頁，便會套用至瀏覽器視窗。

事件處理器

+ +

These are properties of the window object that can be set to establish event handlers for the various things that can happen in the window that might be of interest.

+ +

This interface inherits event handlers from the {{domxref("EventTarget")}} interface and implements event handlers from {{domxref("WindowEventHandlers")}}.

+ +
+

Note: Starting in {{Gecko("9.0")}}, you can now use the syntax if ("onabort" in window) to determine whether or not a given event handler property exists. This is because event handler interfaces have been updated to be proper web IDL interfaces. See DOM event handlers for details.
