New Tutorial on $$() and CSS Selectors

It's been a while since I posted a new tutorial so I figured I was overdue. This tutorial is on Prototype's lesser used $$() function (yes that is not a typo, it really is a double dollar sign) and CSS selectors. The combination of these two tools can lead to some very powerful results and much cleaner markup than putting id= all over the place. Check out this new tutorail here: http://www.michaelminella.com/javascript/css-selectors-and-prototype.html. L...

CSS Selectors and Prototype

Most JavaScript libraries provide some form of the $() function. This function is a short hand version of document.getElementById(). However, I was only recently introduced to the $$() function in Prototype. $$() takes a list of CSS selectors and returns an array of objects that match. This ends up being a much easier and more maintainable way to access elements in the DOM than giving EVERYTHING an id. Although the scope of CSS selectors in general is way to large for this tutorial, we will walk thru a simple use of the $$() function in prototype and introduce you to CSS selectors.
