How does one intercept modal browser alerts about connection problems, file transfer failues and the like from javascript?
Most of all, I want to trap the "The operation timed out when attempting to contact www.kingdomofloathing.com" dialog, which pops up very frequently (typically at least once every session) when I load a new frame from my javascript code. Of course it has nothing to do with which method I employ to load it, but it's mostly when I initiate the transfers myself when I'm really interested in trapping the alert to handle it in a more constructive and less user-involving manner.
Even a solution requiring me to be a Mozilla plugin would be useful, though what I really want is something that could live in a scriptlet or web page and handle the call, ideally cross-browser. With browser Javascript not being nearly as wing-clipped today as it was back in the nineteen hundreds, I've come to expect to be able to solve issues like these. (Let's hope I'm not being overly optimistic.)
Hmm. I suppose due to the lack of talkback features here, I'd better leave a mail address -- feedback to oyasumi at gmail dot com would be very welcome indeed. I'll be sure to write some kind of article about the solution once I find or get pointed to it.
