触发一个事件从一个视图到另一个骨干 [英] fire an event from one view to another in backbone

问题描述

我有一个主视图和主视图里面我有，当我点击一个按钮时生成另一种看法。有没有侦听为从子视图触发的事件父视图的自定义事件的方法。我试着使用jQuery触发通过EL财产做，但没有相当的工作。

I have a main view and inside that main view I have another view that gets created when I click a button. Is there a way to listen for a custom event on the parent view for an event that is fired from the child view. I tried to do it through the el property using jQuery trigger but that didn't quite work.

推荐答案

雅，没问题...你会希望使用事件聚合的格局。这是1号线code的骨干：

Ya, no problem... you'll want to use the "Event Aggregator" pattern. It's 1 line of code in Backbone:

VAR eventAgg = _.extend（{}，Backbone.Events）;

现在，你可以在你的应用程序从该对象触发/绑定事件，无处不在，让您的应用程序的不同部分互相以分离的方式进行通信。

Now can you trigger / bind to events from this object, everywhere in your app, and have the different parts of your app communicate with each other in a decoupled manner.

我用这个有很多！
