如你要提取市的数据，你需要在接受请求页面写如下代码：
shi=trim(request.form("city"))
就可以得到市的值了。
还有这是用Form传递参数，而不是用QueryString传递。
相关问答
Q1: javascript菜单列表二级联动问题？
先弄明白selectedIndex 是什么意思?
selectedIndex 属性可设置或返回下拉列表中被选选项的索引号。
OPTION VALUE="0"请选择所在省份 /OPTION 这个的selectedIndex =0
OPTION VALUE="直辖市"直辖市 /OPTION 这个的selectedIndex =1
如果选了 直辖市
var provinceCity=city[sltProvince.selectedIndex - 1];
也就是：
var provinceCity=city[0];// ["北京","天津","上海","重庆"]
然后城市列表就出现这4个城市
Q2: javascript实现二级联动，比如连个下拉列表，一个选择省份，另一个自动出现相应城市
script language=vbScript
