    copied!<p>I am trying to build a simple crud application with a view of an item and the a listView containing that item view, built from a collection. I want to have a detailView for a specific item, but when switching to this detailView, I do not know how to dispose of the listView properly. I have seen solutions for removing zombies on a single view, but not for a view composed of a collection. Is there any straight forward way to clean up a List view composed of views?</p> <pre><code>var Model = Backbone.Model.extend({ defaults : { id : '', name : '' } }); var Collection = Backbone.Collection.extend({ model : Model }) var HomeView = Backbone.View.extend({ tagName : "div", id : "home-view", initialize : function() { $("body").html(this.el); this.render(); }, render : function() { this.$el.html("&lt;h1&gt;This is the home page&lt;/h1&gt;&lt;a href='#users'&gt;Go to users&lt;/a&gt;"); } }); var UserView = Backbone.View.extend({ tagName : "li", initialize : function(e) { _.bindAll(this, "alertName"); this.render(); }, events : { "click" : "alertName" }, render : function() { this.$el.html("Hi, my name is " + this.model.get('name')); }, alertName : function() { alert(this.model.get('name')); } }); var UsersView = Backbone.View.extend({ tagName : "ul", id : "users-list", subViews : [], initialize : function(e) { $("body").html(this.el); this.collection = new Collection([{ id : '4', name : 'candy' }, { id : '2', name : 'soap' }, { id : '3', name : 'pepper' }]); console.log(this.collection) this.render(); }, render : function() { var self = this; this.collection.forEach(function(model) { var cView = new UserView({ model : model }) self.subViews.push(cView); self.$el.append(cView.el); }) this.$el.after("&lt;a href='#home'&gt;Go to home&lt;/a&gt;"); }, close : function() { while (this.subViews.length) { this.subViews.pop().remove(); } this.remove(); } }); var Router = Backbone.Router.extend({ routes : { "" : "home", "home" : "home", "users" : "users" }, initialize : function(options) { console.log('router') }, home : function(e) { console.log('home') this.loadView(new HomeView()); }, users : function(e) { console.log('users'); this.loadView(new UsersView()); }, loadView : function(view) { this.view &amp;&amp; (this.view.close ? this.view.close() : this.view.remove()); this.view = view; } }); $(document).ready(function() { var router = new Router(); Backbone.history.start({ }); }); </code></pre>
