The DOM is short for: Document Object Model. This is basically a virtual map of the currently loaded web page. You can use this map along with the help of Javascript, to travel about your web page and do things like:
Insert tags
Remove tags
Insert text
… And a whole lot more.
The DOM is the key to all those cool Javascript and Ajax affects that we now see all over the Web. Check out my new video that introduces you to the DOM and I also teach you an exercise I came up with to help you better understand the DOM:
1. Basic object oriented concepts.
2. The Javascript object hierarchy.
The goal of this video is to give you a birds eye view of Javascript, to hopefully make it easier to understand how to use this language in later videos.
I just released and brand new course on the Javascript framework called jQuery. JQuery is a very popular Javascript library that many web designers will find themselves working with.
You can find about 40 minutes of free videos from the course here:
As you may know, I am a big WordPress fan and I use it on a few of my ‘killer’ sites. Anyway, I just discovered that the WordPress nerds have used the Google Gears project to speed up the WordPress admin user interface.
What is Gears?
Gears is basically a browser add-on that allows Javascript code to run much faster. To use Gears, you as a programmer, has to build it into your Javascript code (as the WordPress people did ..) and for people to benefit from Gears, it has to be installed into their browsers.
.. You can learn more about this in this video I just created:
You can install Gears (into your web browser) here:
