php - Jquery event won't fire when element is displayed via mysql -


i have content fed in mysql that, when clicked should fire alert()... however, not working...

here code code fed in php/get_answers.php

<?php session_start(); ?> <?php require_once("../includes/include_all.php"); ?> <?php $answers = $question->get_answers_for_question($_get['id']); ?> <?php while($row = $answers->fetch_array()){ ?>   <!-- answers here -->   <div class = 'answer-row'>     <div class = 'answer-side'>         <div class = 'arrow-contain-answer' type = 'answer' id = 'arrow-up' answer-id = '<?php echo $row["id"]; ?>'></div>         <div class = 'answer-votes-contain'>             <?php echo $row['popularity']; ?>         </div>         <div class = 'arrow-contain-answer' id = 'arrow-down'answer-id = '<?php echo $row["id"]; ?>'></div>       </div>      <div class = 'answer-content'>       <?php          echo $row['content'];       ?>     </div>      <div class = 'actions'>         <a href = '#' class= 'add-comment' id = '<?php echo $row["id"]; ?>'> add comment </a>     </div>    </div>  <?php } ?>

and here jquery on page displayed on:

$(".arrow-contain-answer").click(function(){     alert(); });

what want happen when clicks element class of 'arrow-contain-answer' event occur..

i think have had problems before when elements being 'fed' page via mysql/php.

$(document).on("click", ".arrow-contain-answer", function(){     alert(); });

try way dynamic added elements!
