JQuery + codignater validation.

I need to make a registration page in PHP (codeignater). After that, you need to include form validation using jQuery. I figured it out with php, but I’m stuck on jQuery. Everything seems to be clear, but I can’t put it all together and build it into a logical chain. What plugins to connect? Is Ajax necessary? Help in any way you can, guys!
