Is there any way to automate triggering a custom event?
<p>On my pages I have several different elements that are showing different representations of the underlying data.  I have AJAX that will update the data through a PHP page, but I then want to trigger an update of all the different elements so they reflect the changes.</p>

<p>I'm thinking of binding the independent elements to a custom event "PageUpdate" so that if anything changes, a single event can be fired to update all elements.</p>

<p>I want to know if there is a way to automate this so that the custom event is always triggered when other events are triggered? Or would I have to put <code>$.trigger("PageUpdate")</code> in every other event I want to trigger "PageUpdate"?  Additionally, can I filter out based on the events, when this is triggered? Not all events require a full page update.</p>

<p>The goal is to not have to go back and put <code>.trigger()</code> calls in the old code and to make it so we don't have to remember it for every event going forward.</p>
