I am using this code:
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>
<script type="text/javascript">
$(function(){
$('#country').change(function(){
$.getJSON('dropdown.php',{cmd:'states',country:$('#country').val
()},function(data){
$.each(data,function(index,val){
var option = new Option(val,val);
$('#state').add(option);
});
});
});
});
</script>
This is basically cascading drop down, upon selecting country states
will be shown,
but this line $('#state').add(option); is not adding value to the
select box "state"
also how the select box "state" will be empties via jquery.
