一旦关闭，就无法打开模态

Question

我有问题，如果我打开模态并关闭它然后我不能再打开它，我必须先刷新。

    <?php
    $db = mysqli_query($con, "SELECT * FROM video WHERE video_id ORDER BY video_id ASC") or trigger_error("Päringu viga: " . mysqli_error($con));

  while($video = mysqli_fetch_array($db)) 
  { 
    $sona1 = preg_split( '/ |-/', $video['video_nimi']);
    //$sona1 = str_word_count($video['video_nimi'], 1);
?>
<article class="grid_4 thumbnail-1">
    <h3><span><?php echo $sona1[0]; ?></span> <?php echo $sona1[1]; ?> </h3>
    <figure class="box-img">
      <a href="#<?php echo $video['video_id']; ?>">
    <center> <img src="<?php echo $kohvik['installation_path'] . 'systeem/timthumb.php?src=' . $kohvik['installation_path'] . $video['video_pilt'] . '&h=146&w=280&zc=1'; ?>" style="z-index:1; position: absolute;" height="146" width="280"><img src="http://www.clipartbest.com/cliparts/9Tp/enR/9TpenRLTE.svg" style="z-index:2; position: relative;" height="146" width="280"> </center>
    </a>
    </figure><a href="#_" onclick="stop();" class="lightbox" id="<?php echo $video['video_id']; ?>">
      <div id="videoModal" class="modal hide fade in" tabindex="-1" role="dialog" aria-labelledby="videoModalLabel" aria-hidden="false" style="display: block;">
      <div class="modal-header">
        <button type="button" class="close full-height" data-dismiss="modal" aria-hidden="true" onclick="stop();" id="sule">X</button>
        <h3><?php echo $video['video_nimi']; ?></h3>
      </div>
      <div class="modal-body"><iframe id="test_<?php echo $video['video_id']; ?>" src="<?php echo $video['video_link']; ?>&rel=0" width="870" height="489" frameborder="0" allowfullscreen=""></iframe></div>
      <div class="modal-footer"></div>
  </div>
 </a>
</article>
<script>
function stop(){
    var iframe = document.getElementById('test_<?php echo $video['video_id']; ?>');
    iframe.src = iframe.src;
}
</script>
<?php } ?>

但我可以打开另一个模态，如果我也关闭那个模态然后打开它们都必须刷新。
