Link in Select List

Hi, i want to put a link in the last option of this select list(the array element, like Cádiz, Córdoba,etc), depending of the option the link must be diferent, the problem is i have no idea how to do that i'm a noob in javascript topic.

Here´s an example of my list:

Javascript:

Code:

---

<script languaje="JavaScript">
<!--
provincias = new Array();
provincias[0] = new Array();
provincias[1] = new Array('Almería','Cádiz','Córdoba','Granada','Huelva','Jaén','Málaga','Sevilla');
provincias[2] = new Array('Huesca','Teruel','Zaragoza');
provincias[3] = new Array('Asturias');
provincias[4] = new Array('Baleares');
function cambiar(formulario){
  var i = 0;
  var select1 = formulario['D1'];
  var select2 = formulario['D2'];
  var vector = provincias[select1.selectedIndex];
  if(vector.length)select2.length=vector.length;
  while(vector[i]){
    select2.options[i].value = vector[i];
    select2.options[i].text = vector[i];
    i++;
  }
  select2.options[0].selected = 1;
}
-->
</script>

HTML:

Code:

---

<form method="POST">
  <select name="D1" onchange="cambiar(this.form)">
  <option>-</option>
  <option>Andalucía</option>
  <option>Aragón</option>
  <option>Asturias</option>
