Note: For both plain objects and DOM objects other than window, if a triggered event name matches the name of a property on the object, jQuery will attempt to invoke the property as a method if no event handler calls event.preventDefault(). If this behavior is not desired, use .triggerHandler() instead.

Note: As with .triggerHandler(), when calling .trigger() with an event name matches the name of a property on the object, prefixed by on (e.g. triggering click on window that has a non null onclick method), jQuery will attempt to invoke that property as a method.

Note: When triggering with a plain object that is not array-like but still contains a length property, you should pass the object in an array (e.g. [ { length: 1 } ]).
