![]() Here’s a simple example of using a model: var UserModel = Backbone.Model. Models are where you structure your data. Step 1: Models and Views in BackBoneīackbone can be broken down to two essential concepts: models and views. If you read on, you’ll get a better understanding of how Backbone and the ZingChart extension work together. If are already familiar with these concepts, feel free to skip down to Step 3. These libraries are loaded by the HTML file. Setting Up Working Environment In this tutorial we will add 3 JavaScript library files to set up our working environment, namely Underscore.js, jQuery and Backbone.js files. Backbone and ZingChartīelow is a quick demo and brief explanation of how Backbone works with models, views, and templates. Introduction to Backbone.JS In this session, I will only concentrate on Backbone. It is a simple, clean solution for integrating ZingChart’s interactive charts within a Backbone project. We used that minimalist style with our Backbone extension. The age of the framework and minimal dependencies piqued the interest of the ZingChart team and the possibilities for including an interactive dataviz component within Backbone apps.īackbone also provides a simple, minimalist structure to your app. It’s sole dependency, Underscore, is 5.7kb, minified and gzipped. It can be as simple as a string error message to be displayed, or a complete error object that describes the error. If the attributes are valid, don’t return anything from validate, If they are invalid return an error message. It is also tiny in comparison to Angular, Ember, and React: only 7.3kb, minified and gzipped. The Backbone.js validate Model is validation logic that we want to apply for all the attributes of model. Released in 2010, Backbone is one of the oldest modern (relatively speaking) front-end frameworks. ![]() remains a solid option for web applications. If (jqxhr.While there is plenty of buzz about “hot new” JavaScript frameworks, Backbone.js. The following code shows how to subscribe to an event and then trigger the event: events.on('myEvent', (e: MyEventArg) =>, // lets do something good Instead of creating inter-dependencies among these components, the template uses a "pub/sub" model: The events object, defined in events.ts, acts as an event hub for publishing and subscribing to application events. Backbone provides built-in events with components such as Model, Collection, and View. Syntax: t (attribute) Parameter explanation: attributes: It defines property of a created model. Philosophically, Backbone is an attempt to discover the minimal set of data-structuring (models and collections) and user interface (views and URLs) primitives. Applications often perform multiple operations in response to a user action. The Backbone.js Set model is used to set the value of an attribute in the model. If not, it redirects to the default url (#!/).Įvents are always important when developing loosely coupled components. Next, it creates the default router and checks whether any client-side URL is specified. The application.start method creates the modal views and attaches event handlers for application-level events, such as user sign-in. It maintains configuration and state information that is shared across the application, such as whether the user is signed in. This object initializes the application and acts as the root namespace. ![]() The application is written in TypeScript (.ts files) which are compiled into JavaScript (.js files).Īpplication is defined in application.ts. The client application scripts are located in the ~/Scripts/application folder. Press Ctrl-F5 to build and run the application without debugging, or press F5 to run with debugging.Ĭlicking "My Account" brings up the login page: ![]() In the New Project wizard, select Backbone.js SPA Project. In the list of project templates, select ASP.NET MVC 4 Web Application. In the Templates pane, select Installed Templates and expand the Visual C# node. The template is packaged as a Visual Studio Extension (VSIX) file. Out of the box it provides basic user login functionality, including user sign-up, sign-in, password reset, and user confirmation with basic email templates.ĭownload and install the template by clicking the Download button above. A user can extend Backbone. They contain the interactive data as well as a large part of the logic surrounding it: conversions, validations, computed properties, and access control. The template provides an initial skeleton for developing a Backbone.js application in ASP.NET MVC. Models are the heart of any JavaScript application. The Backbone.js SPA template is designed to get you started quickly building interactive client-side web apps using Backbone.js. The Backbone SPA Template was written by Kazi Manzur Rashid
