2.7 Comments – help me with posting on same page

I have the comments working fine (the “reply to this comment” part does the ajax and inserts a <textarea> for people to comment) but I am wanting it to redirect me to the same page once someone posts the comment.
I have followed this https://ottodestruct.com/blog/2008/09/29/wordpress-27-comments-enhancements/ to get my comments working.

Can anyone give me some direction?
