![]() If any new model is found, the items will be added to that model. It is used to update the collection with set of items in a model. It resets the collection and populates with new array of models or empty the entire collection. It removes a model or array of models from the collection. It is used to add a model or array of models to the collection. It specifies the state of the model and uses backbone.sync to display the state of the collection. It returns the copy of the attributes of a model using JSON format in the collection. It specifies the array of models which are created inside of the collection. Initialize function is defined to create a model instance. You need to override the model property of the collection class. It is used to extend the backbone's collection class to create an own collection. It facilitates you to listen for changes to specific attributes in any model in a collection.įollowing is a list of methods that can be used to manipulate the Backbone.js collection: Index ![]() ![]() If an event is triggered on a model in a collection then this will also be triggered on the collection directly. You can create your own collection by extending the backbone's collection class. It provides helper functions to perform aggregation and computation against a list of models. It handles the loading and saving of new models to the server. It is used to deal with a group of related models. RoutingExample.A collection is an ordered set of models. Here in Backbone is a really simple example of routing by switching between the “Home” and “About” page: var HomeView = () So, whenever you click a link or change an URL in the address bar, that URL change or window.location change is being intercepted on the client, and a new virtual template will be loaded with new data. You need this feature if you’re in a client-side app and virtually switching pages on the client-side. ![]() For a quick example, let’s look at the routing feature of each framework. I’ve written on on my blog before about how to learn JavaScript frameworks quickly, and I also rewritten it for SitePoint. I personally like to think about frameworks by breaking them down to features and giving concrete examples, since I think this really informs a lot of understanding of what’s not there. However, without some context within which to digest those statements, they end up being an opinion about things. Some people can be up in arms and say things such as “You’re just wasting your time,” or “Why learn this stuff that doesn’t matter for JavaScript?”, but from a learning perspective, I think it’s not bad if you’re doing it just to get prepared for actual MVCs, considering how Backbone.js is more like a library than a framework.īasically, I’m sure a lot of relatively new JavaScript developers run across a lot of broad statements where people point out what framework is good, what is better, and what is lacking. If I had to do it again, I think it would have been a much better experience for me to have learned Backbone.js first. My learning path was going from jQuery to Angular before jumping to Backbone, and finally Ember. The summary may vary from the original video and if you see any issues, please let us know! The text summary is written by the Codementor team and is based on the Codementor Office Hours hosted by Craig McKeachie, who authored the JavaScript Framework Guide. If you’re not an advanced JavaScript developer at the point of learning your first framework, what should you pick? This article will give you some ideas and compare AngularJS, Ember.js, and Backbone.js, giving you some code examples for you to get a better idea. ![]()
