Javascript example

Hi, I need to use javascript code, in other words, the 'without plugins' methods to incoorperate reCaptcha into our system. I have managed to get it to show, but now need to verify the user's input. I know I have to use the API call: http://bit.ly/1ovVJTO but don't actually know how to do it within a javascript function and how to get the user's IP address that is a required parameter? I realise this would be 'a piece of cake' for most of you, but not something I have done before, so was hoping someone could provide me with some help or examples to help me?
