This should work:

$('div:not(#myDiv)').hide();  // hide everything that isn't #myDiv
$('#myDiv').appendTo('body');  // move #myDiv up to the body

Update:

If you want to hide EVERYTHING that, not just div elements, use this instead:

$('body > :not(#myDiv)').hide(); //hide all nodes directly under the body
$('#myDiv').appendTo('body');

Probably simpler is to wrap the entire "hideable" part of the page in a big container element, and hide that directly though.

Like so:
