How to play randomly chosen music using JS?

Question

I have button that changes when you press play/pause and I was wondering how should I make it play song randomly.

<a id="play-pause-button" class="fa fa-play"></a>
<script>
var audio = new Audio("audio link");

$('#play-pause-button').on("click",function(){
  if($(this).hasClass('fa-play'))
   {
     $(this).removeClass('fa-play');
     $(this).addClass('fa-pause');
     audio.play();
   }
  else
   {
     $(this).removeClass('fa-pause');
     $(this).addClass('fa-play');
     audio.pause();
   }
});

audio.onended = function() {
     $("#play-pause-button").removeClass('fa-pause');
     $("#play-pause-button").addClass('fa-play');
};
</script>

Thanks in advance!

Answer 1

your musics probably are in an array, to play music randomly, you have to had the length of that array, and use random function to produce random number in a specific range.(this link will help to generate your numbers: Generating random whole numbers in JavaScript in a specific range? )
