Enumerator Object

Description

Enables enumeration of 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 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:

function ShowDriveList()
{
  var fso, s, n, e, x;
  fso = new ActiveXObject("Scripting.FileSystemObject");
  e = new Enumerator(fso.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>";
    }
  return(s);
}
