I am no expert, but I would think that both of those ideas are probably not in your best interest.

Experts, chime in.....

Everything that is on the client side (including html and javascript) can be completely changed/removed by a hacker. For this simple reason putting your defense lines into client-side javascript would be ridiculous. You can secure your application only on the server side: Make sure that the public interface of your server side code can not be abused in any way from the client side. In other words: Make sure that I can not issue an evil crafted request (with fancy parameters) to your server side code (for example with my evil python script) so that it takes an action you don't want as the owner of the site: for example:
- responding to my python script by sending sensitive info from your db or site
- making damage to your db (sql inject) - like deleting a table or entries
....

In your client side script and html you have to make sure that:
- it works as intended (cosmetics)
- it doesn't reveal exploitable info about your server side code
