Ruby form field masking

Hi,

I'm wondering if there is a way to apply a mask to a form field with Ruby. For example, a social security number or phone number format. None of my Ruby or Rails books mentions anything about it.

Thanks!

Edit: I misunderstood.

No, it's best to do the checking rails-side and flash() if there's a problem, otherwise use javascript.

You can use some regular expressions for checking.

ruby Code:

Original - ruby Code
if ($ssn =~ /\d{7}/) then puts "hooray" #their social security number is seven digits (i don't know the exact format, i can help you with the regexp if you give me that though) end

if ($ssn =~ /\d{7}/) then
    puts "hooray" #their social security number is seven digits (i don't know the exact format, i can help you with the regexp if you give me that though)
end
