HI
Sorry to but into your forum but this seems like a good place to ask - hope you don't mind.
I have a form with a simple DDL with numbers 1,2,3,4, etc.
OnChange this displays certain hidden Divs.
This works fine
Bit I am looking for a way to cut down the load time.
The code is fine for say 4 or even 8 hidden Div but what if I have (for example) 40 or 50.
How can I cut this javascript down.
Thanks for looking
Jane
If you load this into a blank page you'll see what I doing and how mad it will start to get with more hidden divs.
