You could simply include it in your request. Try sending the entire
form, not just one field, and then filter to discover the first empty
or default select control to re-populate.
function sendRequest() {
new Ajax.Request("descriptions.php",{
parameters: $('your_form').serialize(),
onComplete: showResponse
});
}
function showResponse(req){
var element = $('your_form).getInputs('select').find(function(elm){
return $F(elm) == 'Your default value or none'}
);
if(element) element.innerHTML= req.responseText;
}
As others on this list have noted, you will probably have trouble in
at least one browser-shaped object with the notion of updating a
select through innerHTML. If you can get your server side to return a
JSON or other structured string instead of raw HTML, you will find it
pretty straightforward to iterate that with each() and build a new
picker using raw DOM commands or the new Element... construction. The
result will actually behave as a form element in all browsers, where
this technique may not.
