Detailed Description

An HTMLCollection is a list of nodes.

An individual node may be accessed by either ordinal index or the node's name or id attributes. Note: Collections in the HTML DOM are assumed to be live meaning that they are automatically updated when the underlying document is changed.

Member Function Documentation

Node HTMLCollection::item ( unsigned long  index) const

This method retrieves a node specified by ordinal index.

Nodes are numbered in tree order (depth-first traversal order).

Parameters
indexThe index of the node to be fetched. The index origin is 0.
Returns
The Node at the corresponding position upon success. A value of null is returned if the index is out of range.

Definition at line 147 of file html_misc.cpp.

unsigned long HTMLCollection::length ( ) const

This attribute specifies the length or size of the list.

Definition at line 141 of file html_misc.cpp.

Node HTMLCollection::namedItem ( const DOMString &  name) const

This method retrieves a Node using a name.

It first searches for a Node with a matching id attribute. If it doesn't find one, it then searches for a Node with a matching name attribute, but only on those elements that are allowed a name attribute.

Parameters
nameThe name of the Node to be fetched.
Returns
The Node with a name or id attribute whose value corresponds to the specified string. Upon failure (e.g., no node with this name exists), returns null .
