autocomplete text input depending on answer of a dropdown - by: Gabriela

hi all,
have a dropdown with a list of provinces. when the user chooses a province I need that next input text box (districts) reads a set of variables for Autocomplete just according to the province that was chosen..

eg: write something like this in the code of the short text (district question):
<script type="text/javascript" charset="utf-8">

$(document).ready(function() {

var province1 = "Anacuabe,Balama,Chiúre,Ibo,Macomia,Mecufi,Meluco,Mocímboa da Praia,Montepuez,Mueda,Muidumbe,Namuno,Nangade,Palma,Pemba Metuge,Quissanga".split(',');

var province2 = "BileneMacia,Chibuto,Chicualacuala,Chigubo,Chókwè,Guijá,Mabalane,Manjacaze,Massangena,Massingir,Xai-Xai".split(',');

});
</script>

so if on the previous question (wich is a dropdown) was chosen province 2, the autocomplete function in this question (short text) reads only the group of districts according to province2.
is tis possible?
thanks you very much
