i'm modifying things as your request.
additionally do you think implementing (wallet) address verification in facuet.html gonna be useful?
if it is, what about using regex to verify with below conditions

1. address has length of 40
2. address starts with 'g1'

Up to you, but would be even better in the backend part of the faucet I think.
