[jQuery] how can I add to different elements inside a jQuery object?


ponder something like this:
var elements = $( '#template_elements' ).html();
$( elements ".mol_row" ).append( "<td>"+ molname +"</td>");
is that the correct way to add to a particular element inside a
cached
jQuery object?
many thanks
