Syntax

object.add(oElement [, iIndex])

Parameters

oElement	Required. Object that specifies the element to add to the collection.
iIndex	Optional. Integer that specifies the index position in the collection where the element is placed. If no value is given, the method places the element at the end of the collection.

This method can be used to add elements only after the page loads.
