[jQuery] grabbing html and putting it back

[hybris77]

anyone. Please look at the following example, useless code since it's
just
grabbing, html and putting it back again but I need to do this and
more inbetween

my problem is that it's just not working, my browser kindof crashing,
not
completely but nearly


        var mol_elements = $( '#molecules_holder' ).html();

        $( "#molecules_holder" ).empty();

        $( "#molecules_holder" ).append( mol_elements );
