It doesn't. All blockUI does it put an iframe over the window and
capture/discard keystrokes. The idea is to block the user from using
the UI until unblockUI is called. Blocking continued execution of
javascript would be self-defeating.
I'm not entirely sure what you're attempting to do, but one thing you
should be aware of is that when you pass a message or DOM element to
blockUI it first discards the current message (via empty()) and then
adds the new one. So if you plan to use a DOM element be sure to
cache it first, like the demo page does. Otherwise the next time you
call this:
$.blockUI($('#dirtyFormMessage')[0]);
jQuery will not find the dirtyFormMessage element.
