moveNext Method (Enumerator) (JavaScript)

Moves the current item to the next item in the collection.

Caution note Caution

This object is supported in Internet Explorer only.

enumObj.moveNext( ) 

The required enumObj reference is any Enumerator object.

If the enumerator is at the end of the collection or the collection is empty, the current item is set to undefined.

In following example, the moveNext method is used to move to the next drive in the Drives collection:

function ShowDrives()
{
    var s = "";
    var bytesPerGB = 1024 * 1024 * 1024;

    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var e = new Enumerator(fso.Drives);

    e.moveFirst();
    while (e.atEnd() == false)
    {
        var drv = e.item();

        s += drv.Path + " - ";

        if (drv.IsReady)
        {
            var freeGB = drv.FreeSpace / bytesPerGB;
            var totalGB = drv.TotalSize / bytesPerGB;

            s += freeGB.toFixed(3) + " GB free of ";
            s += totalGB.toFixed(3) + " GB";
        }
        else
        {
            s += "Not Ready";
        }

        s += "<br />";

        e.moveNext();
    }
    return(s);
}
