Enumerator Object
Language Reference

Description
Provides a way to enumerate items in a collection.
Syntax
new Enumerator(collection)

The collection argument is any collection object.

Remarks
Collections differ from arrays in that the members of a collection are not directly accessible. Instead of using indices, 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:


function ShowDriveList()
{
 var fs, s, n, e, x;
 fs = new ActiveXObject("Scripting.FileSystemObject");
 e = new Enumerator(fs.Drives);
 s = "";
 for (;!e.atEnd();e.moveNext())
 {
 x = e.item();
 s = s + x.DriveLetter;
 s += " - ";
 if (x.DriveType == 3)
 n = x.ShareName;
 else if (x.IsReady)
 n = x.VolumeName;
 else
 n = "[Drive not ready]";
 s += n + "<br>";
 }
 Response.Write(s);
}
