Lista de paises y ciudades

[codig0]

Hola,

Alguien podría ayudarme a encontrar o modificar este código para que haga exactamente lo mismo:

Código:

<script>
/* This script and many more are available free online at

// State lists
var states = new Array();

states['Canada'] = new Array('Alberta','British Columbia','Ontario');
states['Mexico'] = new Array('Baja California','Chihuahua','Jalisco');
states['United States'] = new Array('California','Florida','New York');


// City lists
var cities = new Array();

cities['Canada'] = new Array();
cities['Canada']['Alberta']          = new Array('Edmonton','Calgary');
cities['Canada']['British Columbia'] = new Array('Victoria','Vancouver');
cities['Canada']['Ontario']          = new Array('Toronto','Hamilton');

cities['Mexico'] = new Array();
cities['Mexico']['Baja California'] = new Array('Tijauna','Mexicali');
cities['Mexico']['Chihuahua']       = new Array('Ciudad Juárez','Chihuahua');
cities['Mexico']['Jalisco']         = new Array('Guadalajara','Chapala');

cities['United States'] = new Array();
cities['United States']['California'] = new Array('Los Angeles','San Francisco');
cities['United States']['Florida']    = new Array('Miami','Orlando');
cities['United States']['New York']   = new Array('Buffalo','new York');


function setStates() {
  cntrySel = document.getElementById('country');
  stateList = states[cntrySel.value];
  changeSelect('state', stateList, stateList);
  setCities();
}

function setCities() {
  cntrySel = document.getElementById('country');
  stateSel = document.getElementById('state');
  cityList = cities[cntrySel.value][stateSel.value];
  changeSelect('city', cityList, cityList);
}

function changeSelect(fieldID, newOptions, newValues) {
  selectField = document.getElementById(fieldID);
  selectField.options.length = 0;
  for (i=0; i<newOptions.length; i++) {
    selectField.options[selectField.length] = new Option(newOptions[i], newValues[i]);
  }
}

// Multiple onload function created by: Simon Willison
// http://simonwillison.net/2004/May/26/addLoadEvent/
function addLoadEvent(func) {
  var oldonload = window.onload;
  if (typeof window.onload != 'function') {
    window.onload = func;
  } else {
    window.onload = function() {
      if (oldonload) {
        oldonload();
      }
      func();
    }
  }
}

addLoadEvent(function() {
  setStates();
});
</script>


<fieldset style="width: 230px;">
<legend><strong>Make your selection</strong></legend>
<p>
<form name="test" method="POST" action="processingpage.php">
<table>
<tr>
<td style="text-align: left;">Country:</td>
<td style="text-align: left;">
<select name="country" id="country" onchange="setStates();">
  <option value="Canada">Canada</option>

  <option value="Mexico">Mexico</option>
  <option value="United States">United States</option>
</select>
</td>
</tr><tr>
<td style="text-align: left;">State:</td>
<td style="text-align: left;">
<select name="state" id="state" onchange="setCities();">
  <option value="">Please select a Country</option>
</select>

</td>
</tr><tr>
<td style="text-align: left;">City:</td>
<td style="text-align: left;">
<select name="city"  id="city">
  <option value="">Please select a Country</option>
</select>
</td>
</tr>
</table>
</form>
</fieldset>

pero que pueda añadir las ciudades, los países etc desde el html y no en el javascript, no se si me he explicado con claridad... ya que yo de javascript=0.

saludos.
