I have a view myView and a collection myCollection. When I add a model to myCollection, the add event is triggered by myCollection. How can I have myView listen to that add event?

推荐答案

您可以收集传递给视图，当你实例化它，然后你就可以拥有视图绑定到在初始化方法收集的添加事件。

You can pass the collection to the view when you instantiate it, and then you can have the view bind to the add event on the collection in the initialize method.

下面是一个code例如

Here's a code example

MyView = Backbone.View.extend({
  initialize: function() {
    this.collection.bind('add', this.onModelAdded, this);
  },

  ...other view functions

  onModelAdded: function(addedModel) {
    //do something
  }
}

这是你如何通过集合中，当你实例化视图

And this is how you pass the collection in when you instantiate the view

var view = new MyView({ collection: myCollection });
