Enables enumeration of items in a collection.
enumObj = new Enumerator([collection])
- enumObj
Required. The variable name to which the Enumerator object is assigned.
- collection
Optional. Any Collection object.
Collections differ from arrays in that the members of a collection are not directly accessible. Instead of using indexes, as you would with arrays, you can only move the current item pointer to the first or next element of a collection.
The Enumerator object provides a way to access any member of a collection and behaves similarly to the For...Each statement in VBScript.
The following code shows the usage of the Enumerator object:
var fso = new ActiveXObject("Scripting.FileSystemObject");
var e = new Enumerator(fso.Drives);
var s = "";
do
{
var x = e.item();
s += x.DriveLetter;
s += " - ";
if (x.DriveType == 3)
s += x.ShareName;
else if (x.IsReady)
s += x.VolumeName;
else
s += "[Drive not ready]";
s += "<br />";
e.moveNext();
}
while (!e.atEnd());
document.write (s);
The Enumerator object has no properties.
