Backbone js set8/13/2023 ![]() ![]() The url method, for example, tells Backbone where to sync up our model with our back-end (Rails) model (more on this later). Don't worry if you are not picking all this up - but it's important to try to get the basic concepts before we start writing our app later in this tutorial series (at that point this will become much clearer).īackbone.Model is a backbone.js class that has a bunch of its own convenient methods to use, and we can also define our own or override the defaults. Ok, now we are seriously getting into it (‘told you we'd go quick). something.js.coffee - which, remember, gets transcompiled into pure JavaScript for browsers to read):Ĭlass extends Backbone.Model When your website is loaded, we'll have something like this in an included CoffeeScript (i.e. The Backbone of Backbone.jsīecause it's crazy easy to get lost, at first, when browsing the Backbone.js documentation or Backbone.js tutorials online (most of which expect you to be a software genius of some sort), we'll boil down the different parts for you here and then walk you through building your own app step-by-step later in these tutorials. While these are certainly suitable candidates for us to use throughout the rest of these tutorials, you'll also want to look into the templating tool React.js (had I written this tutorial more recently, I likely would have chosen React and followed this basic line of integration). While this is cool because it's flexible, it makes it difficult for beginners to learn because there are an infinite number of ways to set things up (and thus Googling for help can often land you in someone else's Backbone.js paradigm).īecause of this, we have deliberately chosen to use (and standardize our conventions with) Backbone-on-Rails, CoffeeScript, and Embedded CoffeeScript (Eco) templates. Second, Backbone.js does not care what back-end language or front-end template system (more on this below) you are using, it only needs to work with JSON and the standard front-end languages. ![]() Helpful classes and methods have already been built for you that you can extend to suit your needs. If you want to, you can do all the magic yourself (as many developers do) with tools like jQuery and your own object architectures, observers, AJAX calls, etc., but there are serious advantages to using Backbone.js (or other frameworks like Angular.js, Ember.js, Meteor.js, Sails.js, etc…) because - quite frankly - for most apps there is no reason to reinvent the wheel. Overview of Backbone.jsįirst of all, Backbone.js is meant to help you organize your JavaScript and the manipulation of browser stuff such as the elements in your Document Object Model (DOM) (e.g. This post jumps immediately into tying together the multiple markup and scripting languages that we've introduced thus far, so make sure you've at least scanned the previous posts and let's get going. Var EmployeesCollection = we wrap up the “quick introductions” part of our Introduction to web and mobile development series, here I'll be presenting Backbone.js - a JavaScript framework that plays nicely with jQuery and Ruby on Rails. Define the following Model and Collection objects in Model.js In this folder, add a new JavaScript file and name it as Model.js. Step 2: Add a new folder and name it as ‘Backbone_Custom_Scripts’. In this project, add Backbone and jQuery libraries using the NuGet Package. Step 1: Open Visual Studio 2012/2013 or any Editor of your choice and create a new web application (an empty ASP.NET app if you are using Visual Studio). The method which gets executed for the click event is used to add the model object into the collection and then the collection is rendered using HTML Table. The question then is how to handle them? In the following implementation, we will see that the ‘click’ event for the html button element is handled inside the View object. aspx) already contains HTML elements and you need to handle the DOM events for these elements. In Backbone, the View (UI) is generally rendered using HTML Templates, and elements declared in this Template are accessible to View, but it might be possible that the HTML page (or MVC view or. The Collection declaration allows to store collection of the data, which is later used by the View. The model allows us to define properties to contain data and business logic. To manage data of web applications, Backbone provides a Model creation strategy. We covered some basics of Backbone in a previous article Getting Started with Backbone.js and Rendering a Collection using View ![]() Backbone.js is a lightweight JavaScript library loosely based on the Model-View-Controller (MVC) pattern (it’s not an MVC framework) and it allows developers to create single-page web applications. ![]()
