在Backbone.js中使用Remove事件检测从集合中删除的模型
我的问题是,当我们绑定/侦听集合的add事件时,是否有方法检测从集合中删除的模型 例如:在Backbone.js中使用Remove事件检测从集合中删除的模型,backbone.js,underscore.js,backbone.js-collections,Backbone.js,Underscore.js,Backbone.js Collections,我的问题是,当我们绑定/侦听集合的add事件时,是否有方法检测从集合中删除的模型 例如: this.listenTo(monthsOnBoardCollection, "remove", function(){ //is it possible here to find what got removed from the collection ? } 您有显示传递给事件的参数的 "remove" (model, collection, options) — when a model is
this.listenTo(monthsOnBoardCollection, "remove", function(){
//is it possible here to find what got removed from the collection ?
}
您有显示传递给事件的参数的
"remove" (model, collection, options) — when a model is removed from a collection.
所以基本上是:
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
}
