Discovering jQuery: Simpler, Smarter Web Development

While working on a recent web application project, our team was introduced to jQuery—and it has significantly simplified how we build and interact with web pages.

We were first exposed to it by one of our Interaction Designers, who uses it to rapidly prototype application interfaces. It didn’t take long to see why. With just a few lines of code, we were able to transform static pages into dynamic, interactive experiences—for example, turning a fixed page into a smoothly scrollable one.

🧠 Thinking of the DOM as a Database

One of the most powerful ideas behind jQuery is how it treats the DOM (Document Object Model). You can think of it almost like a database, where the $() selector acts like a query language.

Using selectors, you can easily target:

  • IDs

  • Classes

  • Tags

  • Attributes within elements

From the top-level <html> tag down to the smallest <td> or <span>, everything becomes accessible and manipulatable.

⚙️ Events Made Easy

jQuery also makes it simple to attach behavior to elements in the DOM. Common events include:

  • click

  • dblclick

  • submit

  • and many more

This allows you to create responsive, user-driven interfaces with minimal code.

💡 A Simple Example

Suppose you want to find the first <h3> element with a class of foo and make it stand out visually. With jQuery, it’s as simple as:

$('h3.foo:first').addClass('makeBigger');

This line selects the first matching element and adds a CSS class to it—instantly changing its appearance.

📚 Helpful Resources

If you’re just getting started or want to go deeper, here are a few resources worth exploring:

  • jQuery documentation and tutorials

  • Learning jQuery (PACKT Publishing)

  • jQuery Reference Guide — a comprehensive resource created by contributors from the jQuery community

🚀 Final Thoughts

jQuery has proven to be a powerful tool for simplifying front-end development. Its intuitive syntax and ability to quickly manipulate the DOM make it especially valuable for prototyping and enhancing user interaction.

While modern frameworks continue to evolve, understanding jQuery provides a solid foundation for working with JavaScript and the structure of the web itself.

What are banks for?

A Thought-Provoking Look at Banking The following excerpt, originally published in Punch magazine on April 3, 1957, has circulated widely over the years. It offers a satirical yet insightful look at the mechanics of modern banking—particularly what is often referred to as fractional-reserve banking. This dialogue is also featured in The Creature from Jekyll Island by G. Edward Griffin, a book many have found thought-provoking when exploring the history and structure of the banking system. A Conversation About Banks Q: What are banks for? A: To make money. Q: For the customers? A: For the banks. Q: Why doesn’t bank advertising mention this? A: It would not be in good taste. Q: When banks list large “reserves,” is that money they’ve made? A: Yes, in a sense. Q: And what about their “assets”? A: That is money they use to make more money. Q: Do they keep it in a vault? A: No, they lend it out. Q: Then they don’t actually have it? A: Not in that form, no. ...

On my way home today...

On my way home today from work the view from my car window was a sight to behold.  Moving my hand to my trusty iPhone, invoking the Camera+ app I become very fond of, I took this picture while going down I-215.   Later I dropped by the Macey's grocery store and noticed another beautiful, as well as patriotic site of a giant American flag waving the wind.  I have become impressed with what the iPhone can produce.
