删除事件来检测Backbone.js的

Question

我的问题是从集合中删除的模式，是有办法来检测得到了从集合中删除时，我们绑定/听集合的add事件模型。

为前：

this.listenTo(monthsOnBoardCollection, "remove", function(){ 
    //is it possible here to find what got removed from the collection ? 
} 

Answer 1

你有Catalog of Events，显示的参数被传递给事件。

"remove" (model, collection, options) — when a model is removed from a collection. 

所以它基本上是：

this.listenTo(monthsOnBoardCollection, "remove", function(model, collection, options){ 
    //now you have the model, the collection and the options which were passed to the remove method 
}
