Exists Method (Script Runtime)

Updated: September 2009

Returns true if a specified key exists in the Dictionary object, false if it does not.

                      object 
                      .Exists( 
                      key 
                      )

Object

Required. Always the name of a Dictionary object.

Key

Required. Key value being searched for in the Dictionary object.

The following example illustrates the use of the Exists method.

function keyExists(k)
{
    var fso, s = "";
    d = new ActiveXObject("Scripting.Dictionary");
    d.Add("a", "Athens");
    d.Add("b", "Belgrade");
    d.Add("c", "Cairo");
    if (d.Exists(k))
        s += "Specified key exists.";
    else 
        s += "Specified key does not exist.";
    return(s);
}
Function KeyExists(k)
    Dim d, msg
    Set d = CreateObject("Scripting.Dictionary")
    d.Add "a", "Athens"
    d.Add "b", "Belgrade"
    d.Add "c", "Cairo"
    If d.Exists(k) Then
        msg = "Specified key exists."
    Else
        msg = "Specified key does not exist."
    End If
    KeyExists = msg
End Function
