You could use custom events:
$('#form').bind('hidden',function(){
$(this).children(':input').each(function(){
var t = $(this);
t.data('value', t.val() );
});
}).bind('visible',function(){
$(this).children(':input').each(function(){
var t = $(this);
t.val( t.data('value') );
});
$('#form').hide().trigger('hidden');
$('#form').show().trigger('visible');
there is also a plug-in that implements listeners for all of jQuery's
methods, so you could do something like:
$('form').bind('hide', function(){ });
$('form').hide();
But I couldn't find it. I think Ariel Fresler was involved with it. In
case he's reading this I bet he would be kind enough to provide you
with a link :)
