Key Property

  • 项目

 

Sets a key in a Dictionary object.

Syntax

object.Key(key) = newkey

Arguments

  • object
    Required. Always the name of a Dictionary object.

  • key
    Required. Key value being changed.

  • newkey
    Required. New value that replaces the specified key.

Remarks

If key is not found when changing a key, a new key is created and its associated item is left empty.

The following example illustrates the use of the Key property:

var d;
d = new ActiveXObject("Scripting.Dictionary");

function AddStuff()
{
   var a;
   d.Add("a", "Athens");
   d.Add("b", "Belgrade");
   d.Add("c", "Cairo");
}

function ChangeKey(oldkey, newkey)
{
   var s;
   d.Key("c") = "Ca";
   s = "Key " + oldkey + " changed to " + newkey;
   return(s);
}

Function DicDemo
   Dim d   ' Create some variables.
   Set d = CreateObject("Scripting.Dictionary")
   d.Add "a", "Athens"   ' Add some keys and items.
   d.Add "b", "Belgrade"
   d.Add "c", "Cairo"
   d.Key("c") = "d"   ' Set key for "c" to "d".
   DicDemo = d.Item("d")   ' Return associate item.
End Function
