html - How to get a random song to play using an array in javascript? -


the page loads , rand variable randomizes song. want playagain button pause song , call rand varibale again randomises song again. when press playbutton play different song. playagain button pausing song rand variable not randomizing again. there way fix that?

html:

<audio id="mytrack" controls>     <source src="song1.wav" type = "audio/wav"/> </audio>  <audio id="gd" controls>     <source src="song2.mp3" type = "audio/mp3"/> </audio>  <button type="button" id="playbutton"></button> <button type="button" id="playagain"></button>

javascript:

var mytrackjs = document.getelementbyid('mytrack'); var playbuttonjs = document.getelementbyid('playbutton'); var playagainjs = document.getelementbyid('playagain'); var gdjs = document.getelementbyid('gd');  var audioplaying = [mytrackjs, gdjs]; var rand = audioplaying[math.floor(math.random() * audioplaying.length)];  playbuttonjs.addeventlistener('click', playorpause, false); playagainjs.addeventlistener('click', random, false);  function random() {       var rand = [math.floor(math.random() * audioplaying.length)];     playorpause(); }  function playorpause() {     if (!rand.paused && !rand.ended){         rand.pause();         playbuttonjs.style.backgroundimage = 'url(playbutton.svg)';     }     else{         rand.play();         playbuttonjs.style.backgroundimage = 'url(pausebutton.png)';     } }

since initialized rand variable once, value going remain same throughout.

to see expected results move playorpause function.

function playorpause() {   var rand = audioplaying[math.floor(math.random() * audioplaying.length)];   if (!rand.paused && !rand.ended){     rand.pause();     playbuttonjs.style.backgroundimage = 'url(playbutton.svg)';   } else{     rand.play();     playbuttonjs.style.backgroundimage = 'url(pausebutton.png)';   } }
