| Enumerator | NN n/a IE 4(Win) ECMA n/a | |||
|
If an ActiveX control property or method returns a collection of values, the usual JavaScript approach to collections (treating them as arrays) does not work for such values. The Enumerator object gives JavaScript a way to reference items in such collections by controlling a pointer to the list of items.
