I am no longer with the agency that built Meijer.com, but I am proud to announce the launch, and the fact that jQuery is doing 98% of the heavy lifting. Take a peek at the persistent cart, product previews, and the slider on the homepage. Just about everything you experience here is a precursor to the plugins I built, and that is only what you can see. There is lots going on behind the scenes.
This was an intense effort, but as always, there are numerous changes I would make to the implementation. You know how it goes -- one of those "what exactly was I thinking when I did that" moments. Still, if you want to know how to use jQuery for some intense functionality, check out the "/js/utility_javascript.jsp", and then view the source. If you experience technical difficulties, please do not contact me -- get in touch with CS at Meijer :) Brian Reindel d'bug @ blog.reindel.com
