                <!--/.Content-->

            </div>
        </div>
        <!--Modal: Name-->

javascript和jquery代码是:

<script type="text/javascript">
        jQuery(document).ready(function($) {

// snippet for plyr plugin          
const player = new Plyr('video', {captions: {active: true}});
window.player = player;




 $('#product-video-modal').on('shown.bs.modal', function() {
    var product_vid = document.getElementById("product-vid-src");
    if (product_vid != null) {
      product_vid.pause();
      product_vid.currentTime = 0;
    }
  });
  })
      </script>
