Hello
The Html-Code '<a href="event:action()"' is used to start actions from the textfield. This doesn't work on my old Ipad 2 under Safari (iPad - iOS:8.3 - Safari 8.0 - WebGL).
I have not tested this before, so I can't say if the recent update to IOS 8.3 is the culprit. I didn't test it with other Ipads.
This is reproducable with the "official" Interface-JS-Example "Get a link to current pano view": "Close" in Textfield (after ".. via XML") does not work (krpano 1.18.3)
I tested it too with the old example http:/https://krpano.com/examples/textfield - Same result (krpano 1.19-pr1).
All examples work perfectly well with an alternative browser (iCab Mobile), so it has to do with Safari.
Regards
Wolfgang
