The Frames collection

The Frames Collection

Note : Both Netscape and Internet Explorer support the Frames collection (Netscape call it an array). For properties, methods and events that are supported by frame elements, see the <FRAME> and <IFRAME> topics.

The Frames collection is an ordered, indexed (by source order) array, containing a reference to Window Objects. If the document contains a <BODY> element, then the frames collection contains references to the <IFRAME> elements in the document. If the document contains a <FRAMESET> element, then the frame collection is populated with references to <FRAME> elements. (Note : Netscape doesn't support <IFRAME> and so will only populate the frames collection with references to valid <FRAME> elements. Also, <IFRAME> elements that are referenced across frames/windows can only be accessed through the Document Object).

Properties

length
The length property returns the number of frames in the collection. Note that the length count starts at 1, not 0 as the frames collection index does.

Methods

item
The item method retrieves single items, or sub-collections from the all collection. It accepts the following arguments:

all.item(index)

If index is a number, then the method returns a reference to the frame object at that position in the frames collections index. I.e.

bIsScrolling=document.frames.item(2).scrolling

would make bIsScrolling be a boolean value, depending on the value of the SCROLLING attribute of the referenced frame object.

If the index property is a string value, then the item method returns the first valid frame object that has the NAME or ID used as the string contained in the index argument.
