多个动态模态表单中的jQuery UI datepicker

Question

我在输入包的每个id_pkt中都有动态模态，它会循环播放。但是id = tanggal中的datepicker只出现在第一个表单中。如何循环播放datepicker？

$(document).ready(function(){
        $("#tanggal").datepicker({
        })
        })

<?php  
  $sql = mysql_query("SELECT * FROM paket ORDER BY id_pkt DESC");
  while($row = mysql_fetch_array($sql)){
       echo'
<div class="container">
<div class="wedding">
<div class="col-sm-3">

        <div class="hover-cap-3col">

        <h4>'.$row['jns_lay'].'</h4>
        <h6>'.$row['nm_pkt'].'</h6>
        <p>'.$row['detail'].'</p>
        <p>'.$row['hrg'].'</p>
        
        <a class="btn btn-default" data-toggle="modal" href="#'.$row['id_pkt'].'"><span data-toggle="modal" data-target="#'.$row['id_pkt'].'"></span>BOOK NOW <i class="glyphicon glyphicon-ok"></i></a><br><br>
                </div>
    </div>
    </div>
    </div>
    </div>
  <br><br>';
}
  ?>
