Are you saying that "Sambaplayer" is not set.

<script>
    var xmlhttp = new XMLHttpRequest();
    var url = "https://api.sambavideos.sambatech.com/v1/medias?access_token=847584758475847874858363&pid=3434&sort=DESC&limit=5&filter=id,title,status,qualifier,description,shortDescription,categoryName,files,thumbs";

    xmlhttp.onreadystatechange=function() {
      if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
        myFunction(xmlhttp.responseText);
      }
    };

    xmlhttp.open("GET", url, true);
    xmlhttp.send();

    myFunction(url);
    function myFunction(response) {
        var arr = JSON.parse(JSON.stringify(response));
        var i;
        var out = "<div>";

        for(i = 0; i < arr.length; i++) {
            out += "<a href='#' class='samba-playlist-trigger list-group-item active' data-mediaid=" + arr[i].id + "></a>";
        }
        out += "</div>";
        document.getElementById("id01").innerHTML = out;
    }
</script>

   var player = new SambaPlayer("player", {
   height: 270,
   width: 480,

    evt.target.className = "samba-playlist-trigger list-group-item active";

Hello, welcome to Stackoverflow! It seems to me an error in the library import. Could you kindly provide the HTML code of the file in which you import the Javascript dependencies?

Thank you, Bonifácio. I completed the html code with the so-called Javascripts as you requested.

As I suspected, apparently the problem was the import of the library itself.

I simulated a scenario similar to yours and detected that the error you indicated occurs if you try to reference the Sambaplayer object before importing the library. This is because Javascript is executed as it is referenced in HTML, and if you try to reference an object before the library is loaded, the error will occur.

In this case you have two options:

Move the call code to the Sambaplayer object to fall below the library call:

  <script type="text/javascript" samba-player-api="player" src="http://player.sambatech.com.br/v3/samba.player.api.js"></script>


<script type="text/javascript">
var player = new SambaPlayer("player", {
  height: 270,
  width: 480,
 playlist: null,
  playerParams: {
    volume: 0,
    startOutput: '480p',
    html5: true
  },
  events: {
    "*": "eventListener"
  }
  });

Or call the Sambaplayer object inside a Document.ready, because then the browser will wait until the document is loaded to then run this part of Javascript (and with this previously load the library):

    <script type="text/javascript">  
$(document).ready(function () {
    var player = new SambaPlayer("player", {
      height: 270,
      width: 480,
      playerParams: {
        volume: 0,
        startOutput: '480p',
        html5: true
      },
      events: {
        "*": "eventListener"
      }
    });
});
</script>
