4. Concerning the first thing I need to fix, I am not sure if HTML5
currently provides a solution for. Here's the sitch: because of an extensive
use of CTRL sequences in the interface, the user will sometimes accidentally
do something like CTRL R (which the browser thinks is a refresh command). In
a regular app, if users stand in jeopardy of losing all their work, the app
usually warns them before quitting. The way I found to work around it (that
used to work) was to use onunload="confirm('save before quitting?').
Currently, however, IE seems to have removed my ability to intervene before
it erases all work. onbeforeunload=function (){ fix(everything)} doesn't
seem to help either.
I'm not sure you can automatically save but what you can do is cancel
the unload with a prompt.
What you can do for an "emergency save" is to fire a *synchronous* XHR
during the unload event. This will freeze the UI but since the user was
about to close the page anyway, this shouldn't matter much.
