使用查询中的第一个选择选项实时添加字段

Question

http://www.onderdelenzoeker.nl/

On this website when you select a year it shows a few more fields to choose from and the options are filtered for just that year without refreshing the page or anything.

I cannot figure out how to do this, can someone help me out?

Answer 1

You just have to hook into the change event, and load the other options there. If you have to load those other options dynamically, you'll have to make an AJAX request.
