您希望在哪里填充下拉框？


来自程序或服务器数据库中存储的数据？

这有很大的不同，因为在第一种情况下你只需触发一个填充另一个盒子的JS例程。


在第二种情况下，你让触发的JS例程生成与服务器联系以获取数据（使用Ajax）然后让它填充下一个下拉列表。


这两个选项都是一个解决方案。


罗纳德：酷：

Where do you want your dropdown box to be populated from?

From data that is stored in your program or from a server database?

That makes a big difference, because in the first case you simply trigger a JS routine that fills another box.

In the second case you let the triggered JS routine make contact with the server to get the data (using Ajax) and then let that populate the next dropdown.

For both options is a solution.
