最后,我的需求是监听window.blur的,所以,只能先于原有的监听器的前面先执行判断,条件满足则执行stopImmediatePropagation 来阻止它传递到页面的监听器。
一般界面编程,可以用显示列表的Node作为监听器的优先级,在上方的会比下方的高优先级。 而cocos2d-js没有stopImmediatePropagation,只有stopProgapation,一旦某个监听器中执行了stopProgapation,后续的监听器都不会被执行。这里并没有js/flash的冒泡概念。 如果在上层Node中stopProgapation,那么效果就有点像设置了swallo...

Your issue is that there is nostopPropagationmethod on the$broadcastedevent. broadcast propagates down and stopPropagation (available in$emit) is used to prevent further propagation upwards. So you have 2 options. Either use$emit it('should set vm.opened to true', function(){ event = scope.$...
In this tutorial, you’ll learn how to easily stop mouse event propagation (DOM bubbling) in Vue.js. When you have a Vue.js method called from href tag you’ll experience DOM bubbling. It is a default browser behaviour. When you click on the tag browser will navigate to the href. ...
When I first started working with components in Vue I assumed the event propagation stopped after the first component listening to it got hit. Thats what made sense to me - of course after carefully reading the docs I was aware of the return false; ...

@timvracer One of the reasons I didn't like the workaround you suggested is it ties my implementation to knowing the state of the downshift element to decide whether to stop the propagation of the key event. e.g. If I put the downshift element in a dialog and hit escape when the dow...
