Recap: Spiffy Applications With JavaScript

July 26, 2011 Zerek Welz

For our July 6 event, Mark Casias and Brian Arnold discussed a few examples of using jQuery and JavaScript to tackle a couple of common issues. If you were unable to attend or need a refresher, we've got you covered:


The Basics - What you need to know before starting

Variables and Types

Variables are a container for information

Primitive types

User interaction

The DOM, Document Object Model, is a programmatic representation of your HTML turning your tags into elements(DOM nodes). The DOM is NOT Javascript.

Gathering Info

Using HTML/CSS create a simple interface to make it easy to gather information from our users. We can store this information in data structures that make sense for our application.

Example Applications

Settlers -
Twiffy.js -

Using a technique known as JSON-P we can retrieve info from third party services like Twitter, Flickr and then do something with that information. The Twitter API allows us to search, read and write tweets.

The Advanced Stuff

Other libraries

Summary - What does it all MEAN?!

Javascript applications are all about the information. There are hundreds of approaches. Using a Javascript library or tollkit can simplify things but be aware of your options. Have fun! Don't be afraid to try new things.
