I've a question about dropdown list. How to get the filtered list (in dropdown) from database? Let's say there are 2 dropdowns
. Second dropdown result list will depend on what has been chosen in the First dropdown. Example, if I choose America (in 1st dropdown), then the 2nd dropdown list will show ONLY states in America. I've didn't have problem with this. The problem is when the page (that consists these dropdowns) is loaded. For more clear view, here an example. I choose America (in 1st dropdown)
, then in the 2nd dropdown I choose Alaska
(which is one of the state in America). I save this data in database. After that, I reload the page and found the same data as I inserted. When I try to select another state, says Washington, it list all the state in the world not only in America. I need to select another country first, and then reselect America, after that the list consist only states of America. Any ideas how to make it better? Fyi, the list is from database, not in any jsp.
Any help would been appreciated...
