Enumerator Object (JScript 5.6)
Enables enumeration of items in a collection.
enumObj = new Enumerator([collection])
Arguments
- enumObj
Required. The variable name to which the Enumerator object is assigned.
- collection
Optional. 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.
Example
The following code shows the usage of the Enumerator object:
function ShowDriveList(){
var fso, s, n, e, x; //Declare variables.
fso = new ActiveXObject("Scripting.FileSystemObject");
e = new Enumerator(fso.Drives); //Create Enumerator on Drives.
s = "";
for (;!e.atEnd();e.moveNext()) //Enumerate drives collection.
{
x = e.item();
s = s + x.DriveLetter;
s += " - ";
if (x.DriveType == 3) //See if network drive.
n = x.ShareName; //Get share name
else if (x.IsReady) //See if drive is ready.
n = x.VolumeName; //Get volume name.
else
n = "[Drive not ready]";
s += n + "<br>";
}
return(s); //Return active drive list.
}
Properties
The Enumerator object has no properties.
