core.message('Новый комментарий');
	$.post('/components/comments/addform.php', {target: target, target_id: target_id, parent_id: parent_id}, function(data) {
		if(data){
		  $('#popup_message').html(data);
		  is_form = $('#msgform').html();
		  if(is_form != null){
			 $('#popup_ok').val(core.send).show(); 
		  }
		  $('#popup_progress').hide();
		}
	});
