Beginners Javascript Video Tutorial

October 10, 2009



Today, the Web is a much more sophisticated place (dynamic shopping carts, blogs, DOM scripting, Ajax etc) … a Web that requires much more sophisticated web designers. To be a competitive and modern web designer these days, you have to learn more than just HTML and CSS .

The ‘foundation’ languages of web design today are:

2. CSS
3. Javascript
4. PHP

You don’t have to become a full-fledged nerd coder but you should at least understand the basic concepts and be able to read and write basic scripts. This way, when a client or your boss comes to you with some shopping cart script that he wants you to install … you wont be freaking out because you don’t understand a thing.

So in keeping with my goal of training you guys and girls up, I just wanted to announce my latest video tutorial; a course on Javascript: Beginners Javascript.

… OK, not the most exciting title, but the video tutorials are perfect for people new to programming. Some details:

Beginners Javascript is designed to teach total beginners Javascript programming. By the end of the 5 hrs of video training (over 39 individual videos) you will feel comfortable reading and writing usable Javascript code for everyday web tasks like spawning windows, validating forms and creating simple page effects.

Introduction to the Javascript DOM

September 20, 2009


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:

You can find the entire Javascript beginners course at

Thanks for watching.

Automatic Table Styling with Javascript.

January 10, 2008

A while back a wrote a JavaScript script that automatically styled an HTML table. In a nutshell, the script automatically changes the background color of every 2nd row in an HTML table.

Anyway, someone recently sent me an updated version of the script. You will probably want to read the original article before looking at these changes.

From the email:

I did some simplification on the code for zebrastripes. I don’t bother with the last array bit because TR elements have the bgColor attribute.

trs[i].bgColor = ( i & 1 ) ? stripe_colour_even : stripe_colour_odd;



The complete function:

function stripe_table(id_name) {

var my_table = document.getElementById(id_name);

/* For debugging */
if ( !my_table ) {
alert(“The ID ” + id_name + ” is not found.”);

/* Table may have more than one tbody element */
var tbodies = my_table.getElementsByTagName(“tbody”);

for (var cnt = 0; cnt < tbodies.length; cnt++) { var trs = tbodies[ cnt ].getElementsByTagName("tr"); /* Walk table row for row */ for (var i = 0; i < trs.length; i++) { if (! hasClass(trs[i]) && ! trs[i].style.backgroundColor) { trs[i].bgColor = ( i & 1 ) ? stripe_colour_even : stripe_colour_odd; } } } } }

Matching Columns Script – Update.

February 17, 2007


I decided to create another blog post to make it easier to find the updated version of the important matching columns script – it was buried in the originals article’s comments.


Updated script by: Jonathan del Mar

I have modified the script to work with multiple class groups also with elements with multiple class names

Derived from a script by Alejandro Gervasio.
Modified to work in FireFox by Stefan Mischook for

Modified to work with multiple class groups also with elements with multiple class names
by Jonathan del Mar (dec-14-2006)

How it works: just apply the CSS class of ‘column’ to your pages’ main columns.

to work with different classes

var columns = new Array(’class_name1′, ‘class_name1′…);

by Jonathan del Mar

by default the script will call
and the default class_name is ‘column’
(see the bottom of this script)
by Jonathan del Mar


var divs,contDivs,maxHeight,divHeight,d;

// get all elements in the document



// initialize maximum height value
if (!my_class) {
my_class = ‘column’;

my_regex = new RegExp(’(.* |^)’ + my_class + ‘( .*|$)’);

// iterate over all elements in the document

for(var i=0;i elements with class attribute ‘container’

// modified by Jonathan del Mar to match ‘column’ in multiple classes



// determine height for element




else if({;


// calculate maximum height




// assign maximum height value to all of container elements

for(var i=0;i
var columns = new Array(’class_name1′, ‘class_name2′, …);

to your html header.
