Display Blog Ads Spots in Random Order

To make it fair for everyone who has signed up a jQuery ad on the blog I have wrote a nifty little function to load the ads in a random order. There is also a shuffle button as a demo for creating a random shuffle on the ad spots manually. This function could be made more customisable but does the job.

Try it out for yourself (look at the right sidebar!).

The code

//Function to display ads on the jQuery Blog and shuffle
(function($)
{
   var displayAds = {
       ads: {
           1: {
