reactjs - RCTDirectEventBlock 与 RCTBubblingEventBlock

Question

RCTDirectEventBlock 与 RCTBubblingEventBlock 有什么区别？

Answer 1

似乎没有太多官方文档，Facebook 已关闭并锁定了要求提供更好文档的问题。我发现的一个有用的文档表明这纯粹是一种风格上的差异:

Bubbling events are like DOM events so that a parent component can capture an event fired by its child. Generally these are UI-related, like "the user touched this box". Direct events are not bubbled and are intended for more abstract events like "this image failed to load".
