In this final part in our knockout mini-series, we’ll add a couple more feature to the simple contacts app that we’ve built over the course of the last two tutorials. We’ve already covered the core fundamentals of the library – data-binding, templating, observables and dependant observables – so this part will consolidate what we’ve learned so far.

In this lesson, we will create a CodeIgniter library that allows us to generate data grids automatically for managing any database table. I’ll explain each step required to create this class; so you’ll likely learn some new OOP techniques/concepts in the process!

Learning something new is scary. For me, the biggest issue with picking up a new skill is that I don’t know what I don’t know. Given that, it’s often useful to find a plan for learning whatever you’re interested in. That’s what this post is: your blueprint, your roadmap, your plan of action for learning JavaScript! You don’t have to worry about finding the best resources, sorting out the bad ones, and figuring out what to learn next. It’s all here. Just follow it, step by step.

Twice a month, we revisit some of our readers’ favorite posts from throughout the history of Nettuts+. This tutorial was first published in October, 2010.
The brilliant Stoyan Stefanov, in promotion of his book, “JavaScript Patterns,” was kind enough to contribute an excerpt of the book for our readers, which details the essentials of writing high quality JavaScript, such as avoiding globals, using single var declarations, pre-caching length in loops, following coding conventions, and more.

Uploading files asnychronously can be a pain at the best of times, but when coupled with CodeIgniter, it can be a particularly frustrating experience. I finally found a way that not only works consistently, but keeps to the MVC pattern. Read on to find out how!

I don’t know about you, but I’m always looking for better ways to organize my JavaScript. Recently (only a week or so ago), I’ve discovered what seems to be the best pattern yet. In this tutorial, I’ll introduce you to AMD: Asynchronous Module Definition and RequireJS. Hang on tight; it’ll be a wild ride!

In the first part of this tutorial, we put together a basic example of a list of contacts. The view (the visible representation of the data on the page) was created using a template, along with some other elements bound to methods and properties of the viewModel using data-bind attributes. Some of the values in the viewModel were observable and were monitored for changes which were then propagated to our view automatically.
In this part, we’ll continue building on the example to add additional functionality. For example, if there were a lot of contacts in our model, a useful feature to add would be paging, to break the view up into more manageable sections.

Writing a nifty Chrome Extension honestly isn’t as difficult as you might think. In this tutorial, I’m going to walk you through how I took an API offered by a great domain-name search service, Domai.nr, and created a Chrome extension for them, simply using their API.

In the red corner, weighing in at just 29Kb (uncompressed), is knockout.js; a pure JavaScript library that simplifies the creation of dynamic user interfaces. Knockout is library agnostic, so it can easily be used with any of the most popular JavaScript libraries already available, but it works particularly well with jQuery, and uses jQuery.tmpl as its default templating engine.

We all know we should be testing our code, but we don’t actually do it. I guess it’s fair to say that most of us put it off because, nine times out of ten, it means learning yet another concept. In this tutorial, I’ll introduce you to a great little framework for testing your JavaScript code with ease.
