En un formulario de alta, tengo 3 campos, "Nombre"," Country" y
"Province", country y province son selects dependientes que los
actualizo con un script Jquery:
//webroot/js/list_provinces.js
$(document).ready(function(){
$('#country').live('change', function() {
alert($(this).val());
if($(this).val().length != 0) {
$.getJSON('obtener_provincias',
{
countryId: $(this).val()
},
function(provinces) {
if(provinces !== null) {
populateProvinceList(provinces);
}
});
}
});
});
function populateProvinceList(provinces) {
var options = '';
$.each(provinces, function(index, province) {
options += '<option value="' + index + '">' + province + '</
option>';
});
$('#provincia').html(options);
$('#provincias').show();
Y esto me funciona a la perfeccion.
El problema viene cuando quiero aplicar los mismos selects
dependientes en la edicion del formulario, he mirado con el firebug y
no me devuelve ningun valor JONSON, no se donde puede estar el error,
Si podeis echar un vistazo al codigo, os dejo el controlador y las
vistas de add y edit Cities
