Just_Johnny Posted March 23, 2009 Share Posted March 23, 2009 I'm new to javascript. I've read MANY tutorials, but I'm just not getting it. What I'm trying to accomplish is very simple. (not for me) I have 3 drop-downs. 1st. Populates from simple mysql query. 2nd. Are just static values. 3rd. Needs to populate from database from a query that uses values from 1st and 2nd drop down. When I read tutorials on how to do this I keep getting lost. I've never done anything like this before. Can anybody help?
