Instance Method Details

#meta_events_define_frontend_event(category, event, properties = { }, options = { }) ⇒ Object

Declares a new “frontend event”. A frontend event is, at its core, a binding from a name to (an event name, a set of properties to fire with that event); by default, the name used is just the event name, without its normal prefix (i.e., foo_bar, not ab1_foo_bar).

You declare the frontend event here, on the server side; the server renders into the page this very binding, and the frontend JavaScript (meta_events.js.erb) can pick up that data and expose it by very easy-to-use JavaScript functions.

category is the category for your event;
