Sencha Touch 2 – Navigation View, Templates and Forms

|

This post will build on the example application from the Introduction to Sencha Touch post. We will look at sorting, templates, navigation and forms. Sorting In the existing code new items appear at the bottom of the list. I’d prefer to see the newest items first. After a Sorter is added to the Store, Sencha displays records in the proper order. var store = Ext.create(‘Ext.data.Store’, { storeId: “activityStore”, model: “Activity”, proxy: { type: ‘ajax’, url: ‘exercise.json’ }, sorters: [ {…

From a List to a Details View using jQueryMobile and Backbone.js

|

In my previous post I built a basic application to demonstrate the use of Backbone.js with jQueryMobile (JQM). The introduction can be found here, with a brief subsequent post on sorting collections here. In this post, I would like to add the capability to view the details of the items presented in the list view. The first step is to create a new JQM page to display the details view. JQM makes it pretty easy to add pages to your…

Spring Namespaces Spring provides several namespaces to simplify XML configuration, such as jdbc, tx, aop, etc. We Spring developers are already familiar with the required beans namespace. Spring Namespaces are defined at the top of the XML file. Here we define the namespaces we need to use, and reference the schema (XSD) that validates the XML.

Introduction to Sencha Touch

|

Steve Smith recently looked at jQuery Mobile and Backbone using a simple application that allowed a user to track their daily exercise. I’m going to duplicate his example using Sencha Touch. Sencha Touch is a framework for building mobile applications using HTML5, CSS3, and Javascript.  This example uses the Developer Preview of Sencha Touch 2.0. Here’s what our project looks like. A Sencha Touch application is loaded from an HTML page. The HTML loads CSS and Javascript. Sencha Touch applications…

Spring 3.1 – Environment Profiles

|

Spring 3.1 Environment Profiles Profiles Spring 3.1 now includes support for the long awaited environment aware feature called profiles. Now we can activate profiles in our application, which allows us to define beans by deployment regions, such as “dev”, “qa”, “production”, “cloud”, etc. We also can use this feature for other purposes: defining profiles for performance testing scenarios such as “cached” or “lazyload”. Essential Tokens Spring profiles are enabled using the case insensitive tokens spring.profiles.active or spring_profiles_active. This token can…

Sorting collections with Backbone.js and jQuery Mobile

|

In a previous post, I provided a simple example of rendering an HTML list view using Backbone.js and jQuery Mobile. The code from that example ended up rendering a list like this: Notice that the list is presented in the order that came from the JSON. Also, when items are added to the list, they show up at the bottom. While easy, this isn’t the best. In this post, I’ll add sorting to the backbone collection and make a small…

Introduction to Backbone.js with jQuery Mobile

|

If you are working on a JavaScript heavy application (think jQuery Mobile, etc.), you probably will want to look at some JavaScript libraries to help add structure, consistency and convenience to your applications. One of the JavaScript libraries I’ve used lately is Backbone.js. To quote Backbone themselves, it provides “models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing application over a RESTful…

OpEd: Yammering about Scala, Java, and Winning

|

This is an opinion piece that represents the views of the author, and does not represent the official stance of Chariot Solutions. But sometimes it is fun to weigh in on the news of the day. There has been quite a dust up in the blogosphere about Yammer’s decision to switch from using Scala to Java. Google “yammer switching to scala” and you’ll get a sampling. You can read it for yourself, but the gist of story seems to be…
