Forms processing before submitting?

Hey guys - I usually hang out at the php side, but..

I have a form that I need to tweek out a bit, and it was suggested to me that I use Javascript..

I have a form that needs to display additional fields if a certain check box is selected. I am using php to actually process the form (the form is in 2 parts - form.html and process.php).

I was wanting to do an if/then kinda thing, but have no CLUE how to do it w/ javascript.

Essentially, if a user picks "yes", I want 3 more fields to show up. If they pick "no", continue on to the other questions.

There is a need for this to be done 2x on the same form - the form is to be used by a helpdesk to report outages, etc..

any advice, tips, samples, etc.. is appritiated..
Thanks!

Well, that's not going to be easy to do with Java .

Try asking again in the Html & Javascript forum. You'll get more help there.

(And don't worry, people stumble in here all the time looking for javascript help).

If you are still interested I have come across some nice scripts are www.dynamicdrive.com. I would see if they might have what you are looking for.

I think there is no onClick event for check box. Instead you can use a graphical button that looks like a check box. then put onClick event that point to the javascript function to render additional rows (maybe need to redraw the whole form)
