这样，我们就将这个数组传到js中，并通过第二个下拉列框的onchange来动态改和body的onload来实现一个默认的。 但是有一点问题就是如何将此数组的值进行转换呢？ 请大家关注一下这个问题，看看能不能用asp和js来解决，拿出一个可行的例子出来看看，（关健数据要从数据中读出，而不静态的定好的！）
1. 写一个函数（use vbscript）,runat server，取出记录集并且生成下拉式列表选项（option）
2. 用js控制vb function
3. 在select控件中onselect调用js函数
coolhealth(漫漫追求)：具体怎么访问数据库怎么生成，没有一段通用的代码可以保证贴出来了你拿了就能用的，要看你用什么服务器，什么数据库，机器名（IP），用户名、密码……，再说这里提倡的是问问题——解答问题，不是给分数——换代码。你要的省市选择脚本可以看看：
http://expert.csdn.net/Expert/topic/1093/1093697.xml?temp=.8254511
如果数据量不大就都读出来，否则每次选择都要连接服务器，有这个必要吗，如果要这样做，那就用<iframe>,在你选择后，在这个iframe里执行查询，然后改变对应的下拉表里的值就可以，上面的例子已经告诉你如何删除和添加option，这个会了就没有什么难的了吧
