[Javascript] Arrays

[Bill Marriott]

Thanks Harry,
However your suggestion looked a bit complicated so I came up with the
following function that iterates throught the array twice in a nested
fashion:
(The intriging thing about this code is that the iterations start through
the array from 1 and not 0.)

{
var r = "t";
var i;
  for (i = 1; i < oneWinter.length; i++)
    {
      var cpfk;
      var cpwinter;
      cpfk = oneWinter[i][0];
      cpwinter = oneWinter[i][1];
      var j;
      for (j = 1; j < oneWinter.length; j++)
        {
        if (cpfk == oneWinter[j][0] && i != j &&  cpwinter ==
oneWinter[j][1])
           {
             var r = "f";
           }
        }
    }

if (r=="f")
    {
     return false;
    }
  else
    {
    return true;
    }
}

thanks for your input though

Bill
