This is not working for me. I created script src to my HTML
function eyob1() {
var play1 = document.getElementById("aud").src="eyobmknn/trk1.mp3"
play1.loop = "true";
pley1.play();
}<!DOCTYPE html>
<html >
<head >
<link rel="stylesheet" href="launch.css">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<div onclick="openeyob();" class="eyob" id="eyob">Eyob Mekonnen</div>
<div id="container">
<div onclick="eyob1();" class="eyob1" id="eyob">01 track 01
<script src="lunch.js"></script>
</body>
</html>and I can add src but the sound cannot be played
I answared a similar question here: How to play audio loaded via file input
It's possible to change the src attribute using the method SetAtrribute:
function eyob1() {
var play1 = document.getElementById("aud")
play1.settAtribute('src', "eyobmknn/trk1.mp3")
}
But is important to notice that your code does't have a an element with id='audio'. Your script won't work as it is now.
