i've gotten *so* far using some very helpful & well-defined JS hints & tricks from this site. now its my turn to post a question for a challenge that has me stumped.
BIZ & FUNCTIONAL REQUIREMENTS I NEED TO FULFILL:- I need multiple select-lists, where name is mapped to a DB field.
- Each option in each list needs a numeric value 1-9 (which a type-table will define in the DB, not my dept)
- Each option value needs to trigger a div SHOW containing a script that describes that lists option value, which will also HIDE the current div/script.
- Per requirements, i must build this using select-lists.
PROGRESS & SUCCESS
Using JS + CSS found on this site, I've successfully gotten the appropriate div to show/hide.
MY PROBLEM:
The only way i have found this to work is if the div id = the option value. Which means all value-to-id combos must be unique.
However, I need my option values to remain non-unique (multiple lists with identical value ranges).
Is there a way to acheive this? Using the following JS or any other JS?
DUMMY/TEST CODE DEMONSTRATING MY SCENARIO:
Each list does trigger a SHOW/HIDE of a script div. However, since the div id's are not unique, only the first set if option value ranges are listening to the trigger(s).
