Play a beep sound on button click

You could use an audio tag like this:

    <audio id="audio" src="http://www.soundjay.com/button/beep-07.wav" autoplay="false" ></audio>
    <a onclick="playSound();"> Play</a>
    <script>
    function playSound() {
          var sound = document.getElementById("audio");
          sound.play();
      }
    </script>
