I have this nested combobox that works with php and mysql:
<script language="javascript">
$(document).ready(function(){
$("#bl3").change(function () {
//$("#bl3 option:selected").each(function () {
$("#bl3").each(function () {
elegido2=$(this).val();
$.post("caso2.php", { elegido2: elegido2 }, function(data){
$("#cliente").html(data);
});
});
})
});
</script>
The problem that I have is that, in my machine it runs well, but in the client's machine he pulls the data but also pulls a blank box and does not select the data in the second box automatically.
