This post is part 42 of 92 in the series Programming by Stealth

In this instalment it’s finally time to bring our Cellular Automaton prototypes to life by implementing Conway’s Game of Life. By the end of this instalment we’ll have reached a real milestone — our first web app! Granted, it won’t be a very feature-rich web app, but you have to start somewhere!

As usual, I’ve collected the code files for this instalment into a ZIP file which you can download here. As well as the ZIP file, I’ve also published a tagged release of the bartificer.ca.js code on GitHub which you’ll need for this instalment’s challenge.

PBS 41 of x – Form Events

Filed Under Computers & Tech, Software Development on October 13, 2017 | 1 Comment

This post is part 41 of 92 in the series Programming by Stealth

In this instalment we’ll tie up the last few loose ends related to web forms. With web forms under our belts, we’ll then be ready to pick up where we left off with our cellular automata JavaScript prototypes, and combine our HTML, JavaScript, and CSS skills together to make our first web app – an implementation of Conway’s Game of Life.

This instalment breaks down into two distinct parts – our first look at keyboard interaction with web forms, and a final look at form-related events.

When it comes to keyboard interaction we’ll start by looking at how browsers treat regular web forms, and then we’ll move on to supporting keyboard interaction with custom web form UI elements like the star-rating example from instalment 36.

Finally, we’ll wrap up with a handy reference table summarising the most important webform-related JavaScripts events, giving some guidance on their use.

There’s just one sample file associated with this instalment, and it’s available for download as a ZIP file here.
