RSS Ajax JavaScript ticker
6
In this tutorial, I'll show you how to combine RSS, Ajax, and JavaScript to create a live RSS ticker.

Thanks to Ajax, the conventional roles of server side and client side programming are reversed in an application like this as JavaScript- not PHP- is used to handle much of the work, including parsing the RSS file.

I've learned it's good form to always show your viewers exactly where you're leading them to begin with, so here are a couple of examples of the Ajax style RSS ticker I'll be discussing how to create.

+ Daily 2 ("dailym"): The script will include a different file for each day of the month (1st to 31st).
+ Random ("random"): The script will randomly pick one from the list of files to include.
