![]() For our purpose, I kept the code structure and removed all its logic, and put in our own Backbone model, collection and view. One of its crucial advantages is to be a very lightweight framework. On to the javascript file: ToDo.js has a nice and small Backbone implementation and with helpful comments - I learned the fundamentals of Backbone just by reading the code. The role of the Model is to provide a basic set of functionality for.

The ToDo.js serves as a great base here with all the supporting files and boilerplates set up, so I only had to change the "body" part of the index.html, and modified the css to make it look right. I grabbed the Backbone implementation of ToDo.js to serve as a starting point as well as to learn from the code base.įirst I mocked up the UI with plain HTML and CSS, just to have an idea what the end product will be. I have never done a Backbone app before, and I didn't feel like starting from scratch. (You can see the implemented app here.) The main reason for this idea is that I could lean on Twitter APIs to provide data so I can focus on just the front end with Backbone. The idea is a simple "leaderboard" to rank Rocketeers by the number of "hugs" they received on Twitter - to "hug" a rocketeer, you just add the hashtag "#hugarocketeer" on a tweet mentioning a rocketeer's Twitter handle. Last Friday I decided to use this time to teach myself Backbone.js, with the goal of building a toy app with it in a few hours. js/collections/todos.js var app = app ||, // Add all items in the **Todos** collection at once.Here at Hashrocket, every Friday afternoon is reserved for contributing to open source or learning new skills. Will persist our todo records to HTML5 localStorage. ![]() The collection uses the localStorage adapter to override Backboneâs Implementing our application by returning to the fundamentals: a Todo Now that we have all the HTML that we will need, weâll start Backbone.js is a great client-side MV JavaScript framework that provides structure to JavaScript applications by providing View, Model, Collection, Router.

Weâll start by filling in the #item-template, Ive also set some default attributes, in case no. options: This parameter is used to specify the options like id, name etc. set attribute of all models in backbone collection Ask Question Asked 10 years, 5 months ago Modified 6 years ago Viewed 20k times 18 I understand that using pluck method we can get an array of attributes of each model inside a backbone collection var idsInCollection uck ('id') // outputs 'id1','id2'. In the above code, Ive defined the initialize function which will be fired when the model is created. Save ( attributes, options) Parameters: attributes: This parameter is used to specify the properties of a model. Note: Collection functions work on arrays, objects, and array-like objects such as. The Backbone.JS set() model sets the value of an attribute in the model. Underscore microtemplating can then access the templates, The Backbone.JS Save () model is used to read and save the data of the model every time when it is called. and the tie to go along with jQuerys tux and Backbones suspenders. It is useful when the model is loading to the server or saving to the server. These donât get evaluated by the browser, which just interprets them as A Backbone.js Collections are a group of related models. Templates, which we will use to dynamically create HTML by injecting To complete index.html, we need to add the If you want to follow along, create a directory structure as Into folders representing their application responsibilities: models, Similar to Modelset, the core operation for updating the data contained by the collection. Other application-specific files are also loaded.
