elementsNN 2   IE 3   DOM n/a

A collection of all elements contained within a form. Collection members are sorted in source code order. Internet Explorer lets you use array notation or parentheses to access a single element in the collection. Because each form element includes a type property (starting with Navigator 3 and Internet Explorer 4), scripts can loop through all elements in search of elements of a specific type (e.g., all checkbox elements).
