No worries Brian, I had to do a search on the forums to find the exact time when I had worked on that implementation! I think that iOS 8 extensions may make the interconnection between the html and J easier, as long as J extends that privilege to Safari. I can't claim to be an Apple developer and I haven't chatted with Eric about this since the new iOS has been released, so I am really basing this on on what I have heard developers describe.
I am assuing that you would like me to test the code on an iPad and unfortunately I don't have access to one for the next couple of days. Perhaps someone else can take a run at it. Hope you get some traction on this as I still think that J on an iPad is a bit of a secret with a lot of potential, especially with the new higher powered tablets that Apple has released. Still wondering what it would be like if iBooks had the capability of running J code within their pages.
