(There’s rarely a good reason to host events to help children communicate better with their parents.) Siblings often have a harder time communicating with each other, and they often do so through a common parent. That generally translates into broadcasting from$rootScopeand listening on the sibl...
WebWorkerRenderNode类型,该类有且只有一个类型为NamedEventEmitter的成员变量events 于是,这里就不得不提到NamedEventEmitter类,这个类维护了一个Map类型的容器_listener,存储了事件名称和对应的方法,并提供新增(listen)、删除(unliten)以及触发事件的方法(dispatchEvent)。 由此可见,事件的定义、维护和触发在整个线程间通讯...
