用ajax重定向

Question

I have a method in some controller that is being used to display something inside a twig template. The content of this template depends on the value of a parameter passed to this method.

The code is:

class FooController {
  public function fooBarAction($parameter)
  {
    // do something
    if($_POST)
    {
      // do something
      return $this->redirect('foo_bar');
    }
    return $this->render('AcmeBundle:view.html.twig', [
      'content' => $parameter
    ]);
  }
}

So having some menu in this twig template, I create a couple of links to the foo_bar route with different parameters, like:

<a href="{{ url('foo_bar', {'parameter', 'aaa'}) }}">aaa</a><br>
<a href="{{ url('foo_bar', {'parameter', 'bbb'}) }}">bbb</a>

What if I'd like to do this with ajax, so that the page loads faster? How could I do this?

So far I've created click event in jQuery, that catches the menu clicks, and gets parameter's value, but what now? How do I do this? I have no idea where to begin.

Thanks!
