sending json using $this->output-set_output()

If I'm understanding you, you can't just send something "to" jQuery. jQuery can make a request and have the server respond with some result which you can receive in the callback event of the $.get() request.

Code:

$.get(
  'http://yoursite.com/some_controller/some_method',  //Url making request to
  function(data) {  //callback function
    console.log(data);  //data would be your json sent back from the controller
  }
);
