Menu
I have an audio element in a webpage, and I want to ensure that a user is not still playing it when they leave the page. How can I be sure the audio element is not playing when the page is unloaded? So far, I have the following code, but it doesn't seem to work; the dialog that pops up upon unload reports that playing is false even when the audio is playing:
<!DOCTYPE HTML><html>
<head>
<script><!-- Loading Scripts -->
function unloadTasks(){
if (playing && !window.confirm("A podcast is playing, and navigating away from this page will stop that. Are you sure you want to go?"))
window.alert("Here is where I will stop the page from unloading... somehow");
}
</script>
<script><!-- Player Scripts -->
var playing = false;
function logPlay(){
playing = isPlaying("e1audPlayer");
}
function isPlaying(player){
return document.getElementById(player).currentTime > 0 && !document.getElementById(player).paused && !document.getElementById(player).ended;
}
</script>
</head>
<body onunload="unloadTasks()">
<audio id="e1audPlayer" style="width:100%;" controls="controls" preload="auto" onplaying="logPlay()" onpause="logPlay()">
<source src="http://s.supuhstar.operaunite.com/s/content/pod/ADHD Episode 001.mp3" type="audio/mpeg"/>
<source src="http://s.supuhstar.operaunite.com/s/content/pod/ADHD Episode 001.ogg" type="audio/ogg"/>

Working example

function isPlaying(playerId) {
var player = document.getElementById(playerId);
return !player.paused && !player.ended && 0 < player.currentTime;
}
