So, say I have two select boxes. One with the letters of the alphabet, and a second with a list of names. When I select the letter in the first, how do I, in my onChange function, extract the value I selected in the first box, to determine what values to populate the second box with?

I have a simple form at http://mstramba.com/fb5.html It''s just a <select> and a textarea. The idea is to be able to either type into a text area directly or choose from a list of saved words in the select box. When a new choice is made from the select, it automatically gets inserted into the text area. This code DOES work in I.E6 (on my machine (XP pro), but doesn''t

Hello, I''m trying to get a select field to update a view via the ''onchange'' option. I''ve seen examples of it here in the forum where people hardcode the forms and use javascript to trigger the change (and nearly all have complained that it''s a hack) and I''m wondering if anyone has a more elegant solution using the embedded ruby methods?

Hey everybody! I was just wondering if Rails'' javascript library includes something as simple as making a dropdown that jumps to the link when selected without needing a "submit" button.

I''m trying to rewrite a fusebox-like application (Active4D plugin to 4D database) in RoR/postgres and I''m doing okay - but keep running into things that stump me. It seems like it takes me hours to figure out something that I could have written in pure code in minutes. The select_month and select_day helper has been my latest waste of time.
