temporarily removing and later reinserting a DOM element?

Question

Is there some jquery magic that will let me do the following:

[0- define some element in HTML (eg, a unchecked checkbox)]

1- update its DOM element by s

Answer 1

You may use the clone method:

var els = $('.els'), saved = els.clone (true);
els.remove ();
// .... do other stuff
saved.appendTo ($('.wherever-you-want-to'));

That said, though, it's better to show & hide them (via display: none, for example), than to manipulate the DOM as it's very expensive. If you have to, use DOM insertion & removal (as above), rather than .html (), which recreated a node from the given string every time.
