<!--#include file="Conn.asp"-->
<%sql = "select * from bmx"
set rs=server.createobject("ADODB.Recordset")
rs.open sql,conn,1,1%>
<script language = "JavaScript">
var onecount1;
onecount1=0;
subcat1 = new Array();
<%count = 0
do while not rs.eof%>
subcat1[<%=count%>] = new Array("<%= trim(rs("bm_name"))%>","<%= trim(rs("bmd_id"))%>","<%= trim(rs("id_no"))%>");
<%count = count + 1
rs.movenext
loop
rs.close
set rs=nothing%>
onecount1=<%=count%>;

function changelocation1(addone)
{
document.addform.addtwo_id.length = 0;

var addone_id=addone_id;
var i;
document.addform.addtwo_id.options[0] = new Option('请选择市','');
for (i=0;i < onecount1; i++)
{
if (subcat1[i][1] == addone)
{
document.addform.addtwo_id.options[document.addform.addtwo_id.length] = new Option(subcat1[i][0], subcat1[i][2]);
}
}

}
</script>

<select name="addone_id" onChange="changelocation1(document.addform.addone_id.options[document.addform.addone_id.selectedIndex].value)">
<option value="" selected>请选择</option>
<%
sql="select * from bmd"
set rs=server.createobject("ADODB.Recordset")
rs.open sql,conn,1,1
while not rs.eof%>

<%rs.movenext
wend
