Answer 1

You can loop over all the textareas on the page and validate the contents by using .each

$('textarea').each(function(i){ // do validation here using $(this).val() });

Answer 2

If they are assigned dynamically, add classes so you can select them.

 $('textarea.generated').each (function(i) { });
