Dynamic counter?

Rails
1

Hi,

In a form I have a text area T and a disable text field C (for
counter).
C must show dynamically how many characters have been typed in T.
Should
I go in for a Javascript solution (or Ajax) or is there any other
way?

Thanks,
Ram.

Hey

I think things like this are solved by one simple line of javascript.

Cheers,
Yuri

I needed something similar a few months ago, and wrote some simple
helpers:
