[jQuery] Re: private listeners for global triggers

You can trigger a custom event on any object with trigger(). On the
global document object, for example:

$(document).trigger("myUpdateEvent");

and listen to it like so:

$(document).bind("myUpdateEvent", someFunction);


Fiddling around with the global document object is a bit icky, though.
Better to use a dedicated object that holds your custom events. To let
elements listen to events, you could create a small plugin that takes
a function to execute when the event triggers. Something like:

var eventHolder = {};

$.fn.bindToUpdate = function(f) {
        $(eventHolder).bind("updateEvent", this, function(e) { f.call
(e.data); });
};

$(function() {
        $("#someDiv").bindToUpdate(function() {
                $(this).html("I was updated!");
        });

        $(eventHolder).trigger("updateEvent");
});

Is that what you wanted to do?
