Keys Method

  • 项目

Returns an array containing all existing keys in a Dictionary object.

                      object.Keys( )

Remarks

The object is always the name of a Dictionary object.

The following code illustrates use of the Keys method:

function KeysDemo()
{
   var a, d, i, s;                  // Create some variables.
   d = new ActiveXObject("Scripting.Dictionary");  
   d.Add ("a", "Athens");              // Add some keys and items.
   d.Add ("b", "Belgrade");
   d.Add ("c", "Cairo");
   a = (new VBArray(d.Keys())).toArray();   // Get the keys.
   s = "";
   for (i in a)                  // Iterate the dictionary.
   {
      s += a[i] + " - " + d(a[i]) + "<br>";
   }
   return(s);                     // Return the results.
}

Function DicDemo
   Dim a, d, i   ' 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"
   a = d.Keys   ' Get the keys.
   For i = 0 To d.Count -1 ' Iterate the array.
      s = s & a(i) & "<BR>" ' Return results.
   Next
   DicDemo = s
End Function
