Question

/*
* 
*  Facebox also has a bunch of other hooks:
*
*    loading.facebox
*    beforeReveal.facebox
*    reveal.facebox (aliased as 'afterReveal.facebox')
*    init.facebox
*    afterClose.facebox
*
*/

I’m using Facebox. In source codes I found some hooks, but I can only find one line that use “beforeReveal”:$(document).trigger('beforeReveal.facebox'). I can’t find where it is defined. So I wonder how it works. Hope to get some help. Thx a lot!

Answer 1

Those are simply custom events (while e.g. click is a pre-defined event) that you can subscribe to:

$(document).on('beforeReveal.facebox', function() {
    // This code here is now executed every time before the facebox is revealed,
    // because Facebox triggers this event.
});
