I have been doing some searching and looking on the forum for old topics on the best way to change a select box based on another. So far, I have only been able to get one way to work, and it only works in FireFox (does nothing in I.E.) I''m having a bit of trouble relating a lot of the examples out there into what I am trying to do. Do I use the observe_field, or onchange="<%= remote_function... There are just too many ways. I was told about jQuery having a change method that you pass a function to, but I failed to get that working as well. My issue is that I have 4 list boxes. You choose from the first one and it populates the next two, then you select from the 3rd one and it populates the last one. I have 4 objects; MachineType, Machine, Issue, SubIssue. The MachineType has_many :machines and :issues. The Issue has_many :sub_issues. I placed each select box into it''s own div whose id''s are the same as the model names. <div id="machine_type"> etc.. Is it better to use the options_from_collection_for_select helper, and just type out the select tags, or should I use the select helper such as f.select(:name)? Can anyone give me a good clear example on exactly how to do this? Thanks, ~Jeremy here are a few of the links I checked out that didn''t help me out. http://www.roryhansen.ca/?p=9 http://www.bobbyvandersluis.com/articles/unobtrusivedynamicselect.php#a http://lists.rubyonrails.org/pipermail/rails/2006-January/009728.html http://www.adamhegedus.com/2006/01/19/ajaxed-select-boxes-in-rails/ -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
