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.

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.
