Let us see how we can use backbone.js views to efficiently manage the applications. Objects backed by models that are responsible for rendering the model data on the screen.Observers that keep listening to the DOM events and in case the event fires, taking the appropriate actions.So in a way, we can say that the views are just observers who are listening to the model and UI events which makes them a perfect place to handle all the events and act upon them.

Also, this provides the mechanism to handle the events raised from the model and update the UI and handle UI events and act on them (perform some operations on the model). The view classes are more like a glue that holds an HTML template with the model object. Doing all this using plain HTML and JavaScript/jQuery is a big problem (doable but a nightmare) especially from a maintenance perspective.īackbone.js view greatly helps us when it comes to creating large scale manageable applications. Some UI elements would want to automatically update the values based on the new/updated data.
Every element on the UI will need some actions to happen when the user interacts with them.

The biggest problem while writing JavaScript applications is the spaghetti code that one needs to write just for HTML DOM manipulation. RoutingExample.In this article, we will try to look at the View classes in Backbone.js and see how view classes help us in updating the relevant parts of the application easily. 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.
