Js

      $('#video')[0].play();
    }
    else {
      $('#video')[0].pause();
    }

  })
</script>

active class gets added but it does not pay video

Answer 1

the functions 'play' and 'pause' are not jquery functions, they belong to the DOM element. Now to make it work try to execute your code every 10 miliseconds or something like that. Try:

 var videoElt = document.getElementById('video'); $(document).ready(function () { setInterval(function () { if ($('#mobileapp').hasClass('active')) { videoElt.play(); // to play the video } else { videoElt.pause(); // to pause the video } }, 10); });
