jQuery click() event catch-all?

You can do it like this:

$(document).click(function() {
  $("#boxID").hide();
});

Since the click events will, by default, bubble up to document, this is a "catch all" approach...if you don't want clicks from inside the box to close it, add a .stopPropagation() call on those click events like this:

$("#boxID").click(function(e) {
  e.stopPropagation();
});
