javascript 事件总线架构 [英] javascript event bus architecture

问题描述

在 这个视频 20:50 (相应幻灯片)，Nicholas Zakas 展示了我认为的一个事件总线架构.我不知道与 Bus 交互的调用是否应该是异步的?
第二个问题:如果调用是异步的，应该如何实现?
谢谢

In this video at 20:50 (corresponding slide), Nicholas Zakas presents what I think is an Event Bus architecture. What I don't know is whether the calls that interact with the Bus should be asynchronous or not?
The second question: if the calls are asynchronous, how should they be implemented?
Thank you

推荐答案

我相信它们确实是异步的.

I believe they are asynchronous indeed.

我的猜测是它们的实现方式是使用自定义 DOM 事件.

My guess is that way they seem to be implemented is by using custom DOM events.

这是一种在 javascript 中解耦的有用技术，您可以查看 jQuery 的 trigger 文档，寻找'custom' 字符串以查看如何触发自定义事件.

This is a useful technique for decoupling in javascript and you can check jQuery's trigger docs, look for the 'custom' string to see how to fire a custom event.
