I had a related idea[1] about speeding up DOM removal operations, but
this post got me thinking: would it be possible to use setTimeout to
delay event and data removal altogether?
function kill() {
jQuery.event.remove( this );
jQuery.removeData( this );
};
$.fn.remove = function( selector ) {
if ( !selector || jQuery.filter( selector, [ this ] ).length ) {
var removed = jQuery( "*", this ).add([this]);
setTimeout( function() { removed.each( kill ) }, 10);
if (this.parentNode)
this.parentNode.removeChild( this );
}
};
Not only would this speed DOM removal by delaying what is essentially
GC, but I think it could solve this problem too, since you could
simply use:
$('#foo').remove().clone();
as the clone operation would take place before the events and data are
removed, right?
