Web develolper Pete Freitag offers a nice concise AJAX Tutorial using Prototype – a popular JavaScript library. The tutorial walks you through the steps to create a live zipcode lookup widget. As slick as this little widget is and as easy as it is to use as well you won’t believe how little coding it takes to create it.
Freitag includes all the code that you’ll need to create this Ajax example and I think he chose a good object lesson for helping you to learn Ajax and prototype. Go take a look at it and let us know what you think below.
