This is an example of a javascript “listener” which opens a link in a new window (using a function) if the rel in the a tag is “external”.


function setOnClick() {
if(!document.getElementsByTagName) {
var anchors = document.getElementsByTagName("a");
for (var i=anchors.length; i !=0; i--) {
var a=anchors[i-1];
if (a.rel.indexOf("external") != -1) {
a.onclick = function(){newWin(this.href,'popup1',700,400);
return false;}

In this podcast you told us to use the lang attribute in the body tag. The lang attribute has been removed in the XHTML 1.1 Strict specification. I read that today before listening to your podcast. Just FYI.

Look at the changes in the Specification

I, initially think, that this concept of Unobtrusive Javascript is great idea, but I need to investigate it more to figure out how I can use it in web design.

Thanks for the great shows Den!
