check required in a select
how can i control if a combobox (a select) is not null (index is -1) or if
index is 0 if the first element is for example a null value or simply a
description of the field .
I try to use this
if (combobox.SelectedIndex==0 || combobox.SelectedIndex==-1)
{
alert('obbligatorio');
combobox.focus();
combobox.select();
}
