It really depends on what you are doing.

If you are using ajax, you can set post variables and then grab those in your controller using $this->input->post(). You can also just send them in your url (http://mysite.com/mycontroller/method/js...ar2/jsvar3). If you have a specific example Im sure people could give better answers.
