$(function () {
bulid_select_normal('citybornPro', _location, getProvince(_location, _sub_location, '', 'pro'));
bulid_second('citybornPro', 'citybornCity', _location, _sub_location, getProvince(_location, _sub_location, '', 'city'));
bulid_select_normal('citylivePro', _location, getProvince(_location, _sub_location, '', 'pro'));

我aspx后台通过Request["citybornPro"],Request["citybornCity"]获取的值是数组里面的编号，
我想修改成直接获取中文值，不知道该怎么去修改。。。。。。。另外下拉框后台去读数据库的值也是显示不了
[解决办法]
s = '<option value="'+key+'" checked selected="selected">'+val+'</option>';
你找下js里面和这个差不多的语句
value="'+key+'" 改成value="'+val+'"
你request获取的是value，这里value都是key所以都是编号，把value都换成值就好了
[解决办法]
太长太乱，没仔细看。。
大致看了一下，你大概没搞清楚js中Array和对象的区别，
_sub_location[1]是_sub_location的第二个元素，
_sub_location[1][1001]是_sub_location[1]的第1002个元素，
另外像bulid_second('citybornPro','citybornCity',_location,_sub_location,'')，没仔细看，不知道这几个变量加不加引号有没有区别
