Want Web2.0? Try jQuery

Thu, 09/14/2006 - 14:21 — Sam

For anyone that is thinking of moving their website or web application into the 21st century, many would automatically head for prototype, script.aculo.us, or perhaps the lesser known MooTools (incorporating the more well known moo.fx). But what alternatives are there?, i hear you cry.

I've been experimenting with jQuery, and i have to say that it's simple, intuitive and easy to get into. The way jQuery gets your objects is just like in CSS or XPath. Using the $() notation, jQuery simply gets what you want, and wraps a load of functionality on to the result. Want all the table cells that have a class "red" use $("td.red"). Want to add another class to all those objects, simple, $("td.red").addClass("bigPadding"). You can create elements and use the jQuery methods to insert quickly into the DOM exactly where you need.

It doesn't stop there, because of the way jQuery adds more functionality to an object, anyone else can do the same, which means easy plugin creation. The excellent Interface plugin adds some fantastic effects like those seen in script.aculo.us. It's a plugin, so you don't have to get the effects system if you don't want it, meaning smaller javascript files. If you do want effects, the Interface plugin is cleverly designed to allow you to pick *exactly* the effects you want, and creates a personalised file for you to download, so that you can get the smallest javascript file that you need.

Want Ajax support, you got it, and again it's simple as pie. To load an ajax result into a certain paragraph $("p#id").load("/path/to/url", { name: Sam, occupation: Programmer}, callbackMethod). jQuery also supplies get, post and an advanced ajax method for more complex systems.

I could go on and on about all the little things that make you think "Wow, why haven't i done it like this before!". But before i sign off, i have to mention the documentation. It's great. It covers everything you need, and there's a great community to help you out.

Want one last reason to try jQuery?... it's the underdog!

Here's some sites to help you get started:

Rendering 3D graphics

Rendering 3D graphics is like lighting a stage, both the geometry of the shapes in question and the lighting of it need to be taken into account.

XHTML

People working with front-end related activities focused their efforts on CSS, as browsers started to live up to standards where it was possible to separate content and look-and-feel with XHTML and CSS. For almost 3 years focus was on separating content from design, and front-end from back-end, but soon, around 2005, people felt that the interactivity on the web had declined and with browser supporting standards, maybe we could start looking at JavaScript again with different goggles.
