Button enabling during validation

[sevenhalo]

(This question is a combination of ASP.Net (VS 2003) and javascript. The code in question is mostly javacript.)

If I'm not clear initially, please let me know. This is a little beyond me, and I'm having trouble trying to firgure out where to start.

What I have is a webform that I created using ASP.Net. I added a couple RegularExpressionValidators to the page that validate dates in textboxes (handled client-side). There's also a couple RequiredField controls as well (handled server side). I have strict server side data validation as well, but I'm trying to keep that more towards defensive programming. Also, I like the cosmetic look of client-side validation.

Back on track, what I really want to do is this. If the page isn't validated client-side (which is just the RegEx validation controls); I want to disable buttons client-side.

I have a feeling this is pretty basic JavaScript. I am able to read and follow JS, but I don't have any experience writing it. I'm not asking for code though, this is something I need to learn if I'm going to make webforms. All I'm asking for is a good, related article or tutorial that might assist me. Half my problem is that I don't know what to look for since I really haven't spent enough time with scripting.


Thanks!
