What's this?

template_format() public

Returns a symbolized version of the :format parameter of the request, or :html by default.

EXCEPTION: If the :format parameter is not set, the Accept header will be examined for whether it contains the JavaScript mime type as its first priority. If that’s the case, it will be used. This ensures that Ajax applications can use the same URL to support both JavaScript and non-JavaScript users.
