Retrieves a collection, in source order, of all elements in a given form. This collection can contain any combination of INPUT, SELECT, and TEXTAREA elements.
object.elements(index)
Parameter Description object A FORM element. (index) Optional. An integer or a string specifying the index value of the element to retrieve. Integer indexes are zero-based, meaning the first element in the collection has index 0. A string index is valid only if the string is a name or identifier of at least one element in the document.
This collection is indexed first by name, then by identifier. If duplicate names are found, a collection of those named items is returned. Collections of duplicate names must subsequently be referenced by ordinal position.
