在主干中从一个视图向另一个视图触发事件 [英] fire an event from one view to another in backbone

问题描述

我有一个主视图，在该主视图中，我有另一个视图，当我单击按钮时会创建该视图.有没有办法在父视图上侦听从子视图触发的事件的自定义事件.我尝试使用 jQuery 触发器通过 el 属性执行此操作，但效果不佳.

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

是的，没问题...您会想要使用事件聚合器"模式.这是 Backbone 中的 1 行代码:

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);

现在您可以在应用的任何地方触发/绑定到来自该对象的事件，并让应用的不同部分以解耦方式相互通信.

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.

我经常使用它！
