NodeList object (Object/DOM)

A generic collection of nodes, not presented in any particular order.

Availability:

DOM level - 1
JavaScript - 1.5
JScript - 5.0
Internet Explorer - 5.0
Netscape - 6.0
JavaScript syntax:-myNodeList = myDocument.getElementsByTagName(aTagName)
Argument list:aTagNameThe name of an HTML tag
Object properties:length
Object methods:item()

This object is based on an Array object and contains a set of Node items contained within a DOM hierarchy.

Do not confuse DOM NodeList arrays with Enumerator or Collection objects. The NodeListitem() method is subtly different to the Enumerator.Item() method.
