Definisie en gebruik

Die elementeversameling gee 'n versameling van alle elemente in 'n vorm terug.

Let wel: Die elemente in die versameling word gesorteer soos dit in die bronkode verskyn.

Let wel: Die elemente-versameling gee alle elemente binne die <form>-element terug, nie alle <form>-elemente in die dokument nie. Om alle <form>-elemente in die dokument te kry, gebruik eerder die document.forms -versameling.
