add random youtube video to your web or blogger

watch on youtube

first of all, you must write javascript code like this :

function randomRange(l,h){  var range = (h-l);  var random = Math.floor(Math.random()*range);  if (random === 0){random+=1;}  return l+random;}
function get_random_yid(){        var ids = document.getElementsByClassName("youtube-id");    var idx = randomRange(ids.length,0);    return ids[idx].getAttribute("id");}
function frx_ytb_show(autoPlay){        var videos = document.getElementsByClassName("youtube-frame");      for (var i=0; i<videos.length; i++) {          var youtube = videos[i];          var yid = get_random_yid();        youtube.setAttribute("id", yid);        youtube.style["position"]="relative";          if(autoPlay)           youtube.setAttribute("src",           "https://www.youtube.com/embed/" + youtube.id            + "?autoplay=1&autohide=1&border=0&wmode=opaque&enablejsapi=1");            else            youtube.setAttribute("src",                "https://www.youtube.com/embed/" + youtube.id                 + "?autohide=1&border=0&wmode=opaque");     }}
