It DOES:

For a selected element - and ONLY for this - use:

if(r == my_selected_index) {
    selattr = " selected=\""selected\\"";
} else {
    selattr = ""
}

bankOptNames+="<option value="+r+selattr+"> "+r"  "+
    bankOption+"</option>\n";


> So the question is howto set the selected index for an option list "within a segment of innerHTML".

See above. And you should really try to *LEARN* how to use JavaScript
and HTML and not just do copy & paste.
