window 객체는 DOM 문서를 포함한 브라우처의 창을 나타냅니다. document 속성은 브라우저 창에 로드된 DOM 문서를 가리킵니다. 주어진 문서에 대한 window는 document.defaultView 속성을 사용하여 얻을 수 있습니다.

이 섹션에서는 DOM window 객체에서 사용할 수 있는 모든 메소드와 속성 그리고 이벤트에 대한 간략한 내용과 참조를 제공합니다. window 객체는 Window 인터페이스의 구현체이며, AbstractView 인터페이스를 상속합니다. 일부 추가적인 전역 함수, 네임스페이스, 객체, 인터페이스 그리고 생성자는 일반적으로 window 객체와 관련이 없지만 window 객체에서 이용할 수 있습니다. window 객체에는 JavaScript Reference 와 DOM Reference 가 나열되어 있습니다.

Filefox와 같이 탭이 달린 브라우저의 각각의 탭은 자신만의 window 객체를 포함하고 있습니다. (그리고 만약 확장 프로그램을 작성하는 경우, 브라우저 창 자체도 별도의 창 입니다. - 자세한 내용은 크롬 코드로 작동하는 window 를 참조하십시오.) 즉, window 객체는 동일한 창에서 탭 간에 공유되지 않습니다. 일부 메소드, 즉 window.resizeTo and window.resizeBy 는 전체 window 객체에 적용되지만 대부분의 다른 메소드의 경우, 현재 탭의 window 객체에만 적용됩니다. 일반적으로, 탭과 관련이없는 것은 창과 관련이 있습니다.

Event handlers

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 EventTarget interface and implements event handlers from WindowTimers, WindowBase64, and 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.
