How to add questions in between youtube videos

I was given a task to embed questions in between youtube videos. The questions should appear after a particular timeframe i.e like after 10 seconds and after 30 seconds. I found a javascript file which takes care of the same. Create a div tag in your html page, the id attribute of the div tag should be "player". There is also a div which has a popup with id "myModal" which is used to invoke the popup. You can use any jquery or javascript popup for the same. In this case I have used inbu

Here is the complete code of the file

<script src="https://www.youtube.com/iframe_api"></script>
<script>
      var player,videoid;
      function onYouTubeIframeAPIReady() {
        player = new YT.Player('player', {
          height: '415px',
          width: '780px',
          videoId: 'YOUR_YOUTUBE_VIDEO_ID',
      playerVars: { 'autoplay': 0, 'controls': 1,'autohide':1,'wmode':'opaque' },
          events: {
            'onStateChange': onPlayerStateChange
          }
        });
      }

      var done = false,isQ1displayed=false,isQ2displayed=false;
      function onPlayerStateChange(event) {
          setInterval(function () {
              var current_time = player.getCurrentTime();
              console.log(current_time);
              if(Math.floor(current_time)==10 && isQ1displayed==false)
              {
          $("#myModalLabel").html("Q. Question 1?");   
          pauseVideo();
          isQ1displayed=true;
          done=true;
              }
          else if(Math.floor(current_time)==30 && isQ2displayed==false)
              {
          $("#myModalLabel").html("Q. Question 2?");
          pauseVideo();
          isQ2displayed=true;
          done=true;
              }
          }, 1);
      }
     
      function hidePopup(){
    $('#myModal').modal('hide');
    done=false;
    playVideo();
      }
     
      function showPopup(){
    $('input[type=radio]').each(function() { this.checked = false; });
    $('#myModal').modal({
    backdrop:'static',
    keyboard:false
    });
      }
     
      function pauseVideo() {
          player.pauseVideo();
      showPopup();
      }

      function playVideo() {
          player.playVideo();
      }

      function stopVideo() {
        player.stopVideo();
      }
</script>
