Wrapping an element in Vanilla JavaScript

This is more of a snippet for my own memory — but here is a function to wrap an element (or set of elements with any arbitrary text. jQuery’s solution works well, but there’s no need to include such a heavy library for this small requirement. Additionally, there are many (many) solutions on StackOverflow — […]

Template syntax families Binding simple values Binding values using Scope Blocks Grammars Parsing Consistency leads to Predictability Comparison of popular templating syntaxes String Insertion Iteration If Templating syntax (and language syntax in general) is very interesting.

Arabic web design and web fonts

Going a little way towards displaying Arabic is a native way creates a delightful user experience. Arabic Web-fonts, layout, and language CSS help create that experience.

Javascript Object – Next and Previous Keys

I often need to perform “next” and “previous” operations on standard JavaScript objects or JSON objects. There is no built-in functionality to do this, so here are some helper functions I’ve created to perform these basic operations:

There is a caveat: The EcmaScript specification doesn’t define an order in which keys are returned in […]

Front-end Series: Part 1 – Architecture

This is part 1 in the Front-end Series. As a front-end developer at a large organization, I work daily on architecture, performance, automation, localization, and compatibility, and other topics which I will share during this series.

Creating your own JavaScript Library – part 2 – Event Handling

In Part 1 of Creating your own JavaScript library, we cover the library essentials: library design, creating a solid object constructor, and adding functions by extending the object prototype. This post focuses on extending our basic library with event handling. Out of the box event handling can be accessed  through Javascript and DOM apis, shown […]

Software Engineering principles applied to CSS

Some of my thoughts about CSS developent. Think of more? Share in the comments and I’ll add them to this page! Low Coupling The principle of low coupling suggests that distinct parts of an application be as “stand-alone” as possible. To illustrate: A very decoupled program could be available from the command-line first, then a […]

Custom events system in JavaScript – LightEvents.js

Needing an event subscription and publishing system for a HTML5/canvas game I’m creating, I wrote a very light event system. Anything than can call JavaScript (link, button, etc) can raise an event: LightEvents.publishEvent('event name', data); Subscribing to events is equally easy:

Here is the LightEvents object, demo is embedded below

Quick and reliable ad-rotator

In the course of my work, I’ve created and refined a simple ad rotator. It is built in JavaScript, and does not rely on any library, like jQuery, to function.  In my experience, it defeats ad-block, and loads easily on all mobile, tablet, and desktop browsers. The rotator can be included multiple places on one […]

asp.net – getting user confirmation before a postback

In asp.net web applications, it is common to have dozens — if not hundreds — of user controls that perform postbacks to the server, actions initiated by a user such as a button click.

Full-adders, 32-bit adders in JavaScript

Fascinated by a lecture as part of my CS degree pursuits (there is light at the end of the tunnel!), I  decided to build some digital circuitry beginning with logic gates and ending with a full 32-bit adder. LIVE DEMO So here’s my question: I’ve got a 32-bit adder… What now? Beginning with basic AND, and OR functions, (&& […]

Horizontal vs. Vertical button groups

Button groups are an important part of user interface design, but choosing their orientation can often be difficult. I’d advocate that horizontal groupings are better in most cases — consider this: Imagine that each element on the page is assigned a “Danger Zone” — and area where within one unit of margin of error,  an […]

Interesting interview question #1

During an interview (for a software developer position) with a major employer in the state of Utah, I was asked an interesting programming question: Create a function that, given an integer parameter, will return the middle three digits I mentally wiped the sweat away from my forehead: whew — not computing bigO notation,  inventing a […]
