Problem Space:

You are submitting a html form, which contains many (hidden) form elements that you do not want (or need) sent to the server for processing.

<script type="text/javascript"> 

// do when submit is pressed
// don't send the 'hidden' textarea content
//  its' un-needed and clutters up the post (and wastes bandwidth)
$('form').submit(function() {

  var elements = this.elements;

  for (i=0; i < elements.length; i++) {

    // if textarea id ends in ".tmpl", exclude from post
    if (elements[i].id && elements[i].id.match(/\.tmpl$/)) {

      // could change the val,...
      //$('textarea[name="'+elements[i].id+'"]').val(' ');
      //console.log($('textarea[name="'+elements[i].id+'"]').val());

      // better, to remove element from submit
      $('textarea[name="'+elements[i].id+'"]').attr('disabled', 'disabled');

    }
   }

  //return false; // if false, doesn't submit, good for testing
});

</script>
