JavaScript: The Definitive Guide, 5th Edition

Name

IFrame: an <iframe> in an HTML document — DOM Level 2 HTML: Node → Element → HTMLElement → IFrame

Properties

As explained in the following Description, iframe elements can be accessed as IFrame objects or as Window objects. When accessed as IFrame objects, they inherit properties from HTMLElement and define the additional properties below:

Document contentDocument

The document that holds the content of the <iframe>.

String src

The URL from which the iframe’s content was loaded. Setting this property causes the iframe to load a new document. This property simply mirrors the src attribute of the HTML <iframe> tag.

In addition to these properties, the IFrame object also defines the following properties, which correspond directly to HTML attributes of the <iframe> tag:

Property	Attribute	Description
deprecated String align	align	Alignment with respect to inline content
String frameBorder	frameborder	Set to “0” for borderless frames
String height	height	Height of the viewport in pixels or percent
String longDesc	longdesc	The URL of a frame description
String marginHeight	marginheight	Top and bottom frame margin, in pixels
String marginWidth	marginwidth	Left and right frame margin, in pixels
String name	name	The name of the frame, for DOM Level 0 lookup and form and link targets
String scrolling	scrolling	Frame scroll policy: “auto”, “yes”, or “no”
String width	width	Width of the viewport in pixels ...
