delay jQuery's trigger() to prevent queueing

gistfile1.js

// Like jQuery's trigger(), only the firing of the event can be delayed by the
// specified duration (in milliseconds). The timer is reset on consecutive
// triggers with the same event name, so only the most recent event will be
// triggered when the duration ends. Useful if you need to prevent events from
// queueing up.
//
//   $('#foo').bind('myEventName', function() {alert('hai')});
//   ...
//   $('#foo').delayedTrigger(1000, 'myEventName', 'event1');
//   $('#foo').delayedTrigger(1000, 'myEventName', 'event2');
//   $('#foo').delayedTrigger(1000, 'myEventName', 'event3');
//
//   // Only event3 is triggered after 1 second passes.
//
$.fn.delayedTrigger = function(duration, eventName, event) {
  var target = this;
  var timeoutId = $.delayedEvents[eventName];
  if (timeoutId) {
    clearTimeout(timeoutId);
  }
  $.delayedEvents[eventName] = setTimeout(function() { 
    delete $.delayedEvents[eventName];
    target.trigger(eventName, event);
  }, duration);
}
$.delayedEvents = {};
