DOM:document

From MDC

« Gecko DOM 参考

在 DOM 中, document 对象提供了一个表示 HTML、XHTML 和 XML 文档的一般方法。Document 对象实现了一般 DOM 核心文档 接口。

除了一般的 DOM 核心文档接口， HTML document 还实现了 DOM HTMLDocument 接口, 它是个用于处理 HTML 文档的更为特殊化的接口(例如， document.cookie, document.alinkColor)。此处列出的属性和方法有部分属于这一更为特殊化的接口，用星号(*)标出。

document 包含于 window 对象内，并可能包含任意多个 elements。

document 接口提供了对 document 类型、它的颜色和格式、插件和 applets 等的访问，也提供了创建和维护所有文档的子结点或者 BODY 和 TABLE 之类元素的方法。

[编辑] Event Handlers

Firefox 3 introduces two new events: "online" and "offline". These two events are fired on the <body> of each page when the browser switches between online and offline mode. Additionally, the events bubble up from document.body, to document, ending at window. Both events are non-cancellable (you can't prevent the user from coming online, or going offline). For more info see Online_and_offline_events.

document.ononline New in Firefox 3
Returns the event handling code for the online event.
document.onoffline New in Firefox 3
Returns the event handling code for the offline event.
