Answer 1

jQuery的trigger功能不一样dispatch，见下表来自bugs.jquery.com/ticket/11047

"The trigger function should also dispatch custom events such that code using addEventListener can catch the custom event. However, that is not happening. In fact, that is the only of the 8 combinations listed below that does not work. We should fix this to allow better interoperability between jQuery event functions and W3C DOM event functions."
