关于options的问题

请问我想把库中的省份和城市取出后显示出来：辽宁省 大连，取出后还可以修改，应该怎么修改下面的代码呢？
<script language=javascript>
function province()
{
var e = document.formform.province;
for (var i=0; i<provinceName.length; i++)
e.options.add(new Option(provinceName[i], provinceID[i]));
}
function cityName(n)
{
var e = document.formform.city;
e.options.length = 1;
if (n == 0) return;
var a = eval("city"+ n); //得到城市的数组名
var b = eval("cityid"+n);
for (var i=0; i<a.length; i++)
e.options.add(new Option(a[i], b[i]));
}
window.attachEvent("onload",province); //初始时给省名下拉框赋内容
</script>

<%
set rs_sec=server.CreateObject("adodb.recordset")
sql="select * from v_section where f_city_id="&rs_user("f_user_city_id")
rs_sec.open sql,conn,0,1%><select name=province onchange="cityName(this.selectedIndex)">
<option value="">-请选择-</option>
</select> <select name=city>
<option value="">-请选择-</option>
</select>
