Hi, I''m new to rails/ruby having come from PHP and am just starting to get my head round how easy it can be :) However, can anyone point me in the right direction for dynamicaly updating a select box based upon the choice of a previous select box, without a page refresh. Any and all help greatly appreciated. Thanks -- Posted via http://www.ruby-forum.com/.
Using RJS calls with an observe_field is the way to go. Works great in FF but you cannot do this in IE by using RJS alone. The reason is that RJS uses the innerHTML method to replace content with a page.html_replace call. IE does not support the innerHTML call on select boxes. You would need to implement it in javascript completely. The only way that I can think of (maybe) is to use a javascript array and update the array from an RJS call.

My approach was exactly that.... My select box was monitored by an observer.. The observer called another action that rendered the partial for the second select box.

I did try to rip out the entire select box and replace it, but for some reason that I still havn''t worked out, once I replaced the select box, the observe_field didn''t work anymore so my next box (I had 3) was never going to update.

You can do it with mostly javascript. Here is an Ajax ''double select'' widget, in object-oriented, cross-browser JavaScript. Very easy to plug and play: http://www.webonweboff.com/widgets/ajax/ajax_linked_selection.aspx Article includes a demo, source code, explanations. The page that actually retrieves the db data will need to be in your web language of choice, of course.

Another option is to observe and redraw the entire form, rather than just field-by-field. I have my entire form in a partial, and I use RJS to redraw the partial from an observe_form event - anytime anything changes in the form, the entire form is redrawn and this accomplishes 2x, 3x, Nx select box updates. c.

You can find it at http://rails.techno-weenie.net/tip/2006/6/20/cascading_select_boxes_with_rjs_even_on_ie But this is far from perfect. Kevins has given an alternative solution as well, but the one that I''m after I can''t seem to find. Shortly after I posted the tip on http://rails.techno-weenie.netTechnoweenie, aka Rick Olson posted a much better solution. Since then there has been some db issues at rails weenie and I can''t find it. Rick if you catch this post can you please provide a link to the tip you posted.
