This is a little program I use to time cookies (the oven baked kind) because I can't hear the stove's timer from where my PC is. I was wondering if there is a way that I can play a sound wav as an alarm instead of the popup alert.

Code:
<html>
<head>
 
<script>
function countdown(){
     x=frmcountdown.counter.value;
     x--;
     frmcountdown.counter.value=x;
     if (x>0){
          setTimeout("countdown()",1000);
     }
     else{
          alert("Cookies are done!");
     }
}
 
</script>
</head.
 
><body>
<form name="frmcountdown">
 
<input type="text" name="counter" size="3" value=720 />
<input type="button" value="start" onclick='setTimeout("countdown()",1000);'>
<input type="reset" value="reset">
</form>
 
</body>
</html>
