Javascript performance - Part 1 - Closures vs Object properties
2007-12-14 02:42:00
Performance may not be a concern on small scripts / widgets that run only once or at most a couple of times per page view, but it should be something to consider when creating a big application with scripts continuously running and a relatively large collection of objects in memory. I decided to run a ...

In a classical inheritance system, objects derive from classes and classes can derive from other classes to. Lets use the famous pets example and construct a very simple application in java. First ...

The ?delete? keyword in JavaScript
2007-12-06 02:32:00
There is a rather unknown keyword in javascript, the delete keyword, that it doesn’t look very useful at a first glance, and it really isn’t, but that’s always a good tool to have in our mind. Actually I’ve only used it once some years ago, until today… What it does is to unset a given ...

I wrote a post a month ago about my newDom Handling Methods , but I made a huge mistake involving IE. At that time my hard disk had broken, and I had to reinstall the whole system. I don’t use windows so IE is not an option, however, because IE is still the most popular browser, ...

Today I helped a guy in a forum. He was needing a simple slideshow script for his webpage, and he borrowed one for one of those many script pages.

Semi transparent HTML elements without affecting the content
2007-11-27 14:16:00
UPDATE: I received some complaints about this script not working under ie6. I build this script to run on a intranet page that I knew that was only to be viewed with firefox. It’s very simple to tweak it, however I’ve updated the script (just the simplified version) to be used with IE6 as well. ...

Faster DHTML animations
2007-11-26 18:22:00
After almost a month I decided to write another post. I have been involved in a very cool project that used and abused DHTML animations, and I’ve invented or discovered some cool techniques, that I now want to share. Why DHTML for animations and not Flash or Java FX? Of course that for the more extreme animations we ...
