When you register a
delegated event

using on (or the deprecated delegate / live), it is somewhat hard to manually trigger these events manually, e.g. for testing.
After trying jQuery's
trigger
Show archive.org snapshot
to no avail, I had success by using native Javascript methods to create and dispatch an event. For instance, to trigger a mousedown event:
element = $('...').get(0);
event = new MouseEvent('mousedown', { view: window, cancelable: true, bubbles: true });
element.dispatchEvent(event);
element can be the delegate target or one of its descendants.
Also see the list of event classes on MDN Show archive.org snapshot .
Internet Explorer
Internet Explorer doesn't allow you to instantiate a MouseEvent directly. Instead you need to do this:
var event = document.createEvent("MouseEvents");
event.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
See this code Show archive.org snapshot for a method that attempts to normalize both approaches.
