Name
HTMLDocument.all[]: all HTML elements in a document — IE 4
Synopsis
document.all[i]document.all[name]document.all.tags(tagname)
Description
all[] is a versatile
array-like object that provides access to all the HTML elements in a
document. The all[] array
originated in IE 4 and has been adopted by a number of other
browsers. It has been superseded by the standard getElementById( ) and getElementsByTagName( ) methods of the
Document interface, and the standard getElementsByName( ) method of the
HTMLDocument interface. Despite this, the all[] array is still used in existing
code.
all[] contains the elements
in source order, and you can extract them directly from the array if
you know their exact numeric position within the array. It is more
common, however, to use the all[]
array to retrieve elements by the value of their name or id HTML attributes. If more than one
element has the specified name, using that name as an index into
all[] returns an array of
elements that share the name.
all.tags( ) is passed a tag
name and returns an array of HTML elements of the specified
type.
