金牌真言师微盘:关于asp 2级分类变3级分类的关联

我这有一个二级分类，我想把它变成三级分类的 ，其中的关联怎么弄，二级分类的代码如下：<script language = "JavaScript">
var onecount;
subcat = new Array();
<%
count = 0
do while not rs.eof
%>
subcat[<%=count%>] = new Array("<%= trim(rs("SmallClassName"))%>","<%= trim(rs("BigClassName"))%>","<%= trim(rs("SmallClassName"))%>");
====应该就是这一块的变动的 <%
count = count + 1
rs.movenext
loop
rs.close
%>
onecount=<%=count%>;

function changelocation(locationid)
{
document.myform.SmallClassName.length = 1;
var locationid=locationid;
var i;
for (i=0;i < onecount; i++)
{
if (subcat[i][1] == locationid)
{
document.myform.SmallClassName.options[document.myform.SmallClassName.length] = new Option(subcat[i][0], subcat[i][2]);
}
}
}

function AddItem(strFileName){
document.myform.IncludePic.checked=true;
document.myform.DefaultPicUrl.value=strFileName;
document.myform.DefaultPicList.options[document.myform.DefaultPicList.length]=new Option(strFileName,strFileName);
document.myform.DefaultPicList.selectedIndex+=1;
if(document.myform.UploadFiles.value==''){
document.myform.UploadFiles.value=strFileName;
}
else{
document.myform.UploadFiles.value=document.myform.UploadFiles.value+"|"+strFileName;
}
}

function CheckForm()
{
if (editor.EditMode.checked==true)
document.myform.Content.value=editor.HtmlEdit.document.body.innerText;
else
document.myform.Content.value=editor.HtmlEdit.document.body.innerHTML;

if (document.myform.Title.value=="")
{
alert("sfsdaasdfasf");
document.myform.Title.focus();
return false;
}
if (document.myform.Product_Id.value=="")
{
alert("dafdsf");
document.myform.Key.focus();
return false;
}

if (document.myform.Content.value=="")
{
alert("123123");
editor.HtmlEdit.focus();
return false;
}
return true;
}

</script>
