HI
Capcha verification will be doing form Server side. and you can make filed validation is required so that if it empty then it shows required validation error.

Thanks
already I have done it from server side but I am looking it client side

I am not sure but May be you can make ajax call onchange event and validate.

You can call service to validate captcha using ajax.
That is better way for client side validation.

This is ridiculous. You're going to pass the captcha value, perhaps as javascript or something, to verify on client side. This of course fails because the bad script kiddies will figure out how to programmatically bypass your captcha because you've given them everything they need to do so.

Which begs the question, why do a captcha at all? If you're not going to protect it, it serves no purpose.

This is a good case for choosing the proper location for asking a question: I didn't even read the question to the point that I could come up with an answer when it was initially posted in the german language forum. Today just seeing the question's title in "Recent Changes" triggered exactly the thought that you (David) posted.

This is not the spam bot you're looking for (makes waving hand movement)

"Could I see your legitimation please?" - "You don't need to, it's ok" - "Oh, nice. Welcome..."
