The same way you do it in a non-rails web form:

http://www.google.com/search?q=javascript+form+validation

unless there is a tool I am not aware of, you have to code by yourself. You
need to observe each field of the form (with prototype.js) and  when it has
changed, you need to validate with help of regular expressions.

Hope that gets you started.

You could also take a look at the sourcecode and examples of the dojo
toolkit, there it is implemented as described above.

I developed an ajax-based validation plugin.  It uses your models validation
rules to validate form data on the server-side in real-time.  You can then
mark/unmark form fields based on their state (valid/invalid) using css.
Download and see the readme.txt for more info.
