How AJAX calls work with TWIG

Question

I am trying to understand how Twig can load a template through AJAX. From their website, it is clear how to load a template (http://twig.sensiolabs.org/doc/api.html)

<         


        

Answer 1

Directly in the template:

{% if app.request.isXmlHttpRequest() %}
  // code if ajax request
{% else %}
  // code if not ajax request
{% endif %}
