.attributes is a collection of all attribute nodes registered to the specified node.
.attributes is a collection of all attribute nodes registered to the specified node. It is a NamedNodeMap,not an Array, so it has no Array methods and the Attr nodes' indexes may differ among browsers. To be more specific, attribute is a key value pair of strings that represents any information regarding that node; it cannot hold Object. Attribute can hold additional data/information that is required while processing custom JavaScript. There are many predefined attributes for different nodes used for binding events, validations, and specifying layout informations that are handled by browser (may vary from browser to browser).

When an HTML document has been switched to designMode, the document object exposes the execCommand method which allows one to run commands to manipulate the contents of the editable region.
When an HTML document has been switched to designMode, the document object exposes the execCommand method which allows one to run commands to manipulate the contents of the editable region. Most commands affect the document's selection (bold, italics, etc), while others insert new elements (adding a link) or affect an entire line (indenting). When using contentEditable, calling execCommand will affect the currently active editable element.
This method never did anything and always threw an exception, so it was removed in Gecko 14.0 (Firefox 14.0 / Thunderbird 14.0 / SeaMonkey 2.11).
The Document method exitFullscreen() requests that the element on this document which is currently being presented in full-screen mode be taken out of full-screen mode, restoring the previous state of the screen.
The Document method exitFullscreen() requests that the element on this document which is currently being presented in full-screen mode be taken out of full-screen mode, restoring the previous state of the screen. This usually reverses the effects of a previous call to Element.requestFullscreen().
The exception is if another element was already in full-screen mode when the current element was placed into full-screen mode using requestFullscreen(). In that case, the previous full-screen element is restored to full-screen status instead. In essence, a stack of full-screen elements is maintained.
The exitPointerLock asynchronously releases a pointer lock previously requested through Element.requestPointerLock.
