![]() ![]() It leverages JavaScript functions to provide various functionalities. It helps in developing the user interface in a sophisticated manner preventing the developers from messing up the large code written for the user interface. After completing this Backbone JS Tutorial, you will find it very easy to endorse the development of simple or complex web applications with the help of this library.īackbone JS Tutorial – Certificate of Completionīackbone JS can be defined as a JavaScript library that enables one to develop the client-side application which could be very simple and easy to interact with. This will be almost three-hour-long video training which includes everything that one needs to know to begin working with Backbone JS. Though there will be some hints associated with the questions, you will need to execute it in your system. We have also added some of the sample questions that you will need to solve at your end. To make it very easy for the trainees to understand the concepts, we have included various examples that are selected carefully so that it could emit a complete idea about any particular concept. Once everything is up and starts working, we will be jumping to explore some of the examples. The educator will show you how to get started with Backbone JS and how to set up things. After the introduction part, we will start doing things practically. In the introduction, the educator will be explaining the purpose of this library and how it endorses the development of complicated web applications in a sophisticated manner. The course will begin with a brief introduction to Backbone JS. The entire course has been covered in a single unit. ![]() MODULE 1: Essentials JS Training Courses.We can also remove a specific element from the collection using the following command:Ĭhocolate_box.remove(Chocolate_box.using get to access the model using its Id.Ĭonsole.log("Accessing element by ID", Chocolate_box.get("c1")) First through index position and second through their cid values the client-ID values given to each object.Ĭonsole.log("Accessing element by index", Chocolate_box.at(0)) Therefore, we can access each element in two ways. This collection stores the data as an array.the Ids of models represented by our box ![]() These can be accessed individually by the following commands: Length, models, and Id of objects inside our collection. By default, every collection stores a few attributes. I have added some of my favorite chocolates below:Ĭhocolate_box.add(new Chocolate()) Define a new Chocolate_box and add some chocolates inside it using the.Under the tag, define a new Model for single Chocolate and also Collection for a box:.Define the jQuery and backbone links that can be used to initialize backbone objects and collections under the tag:.So, you want to create a collection of chocolates in a chocolate box. Let’s look at the solved example below to understand it further. In simpler words, a collection is is a group of models. This allows you to listen in one place for any change that might happen to any model in the collection. Aside from their own events, collections also proxy through all of the events that occur to models within them. It loads and saves new models to the server and provides helper functions for performing aggregations or computations against a list of models. It then all connects to your existing API over a RESTful JSON interface.Ī Collection helps you deal with a group of related models. Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, and views with declarative event handling. ![]()
