The code is below. How would you set a button to pause the timer and resume when pressing resume? The // marks below are where I’m placing my pause and resume tags. Thank you for all of your help!!

<head>
<script type="text/javascript">

var d1 = new Date();
d1.setHours(1,0,0);

function f(){
var h= d1.getHours();
var m= d1.getMinutes();
var s=d1.getSeconds();
m= (m<10)?"0"+m: m;
s= (s<10)? "0"+s : s;

var el= document.getElementById("inputid");
el.value= h+":"+m+":"+s;
d1.setSeconds(d1.getSeconds()-1);
if( h==0 && m==0 && s==0 ) clearTimeout(t)
var t= setTimeout("f()",1000);
}

</script>
</head>
<body>
<form><input type="text" id="inputid"></form>
<script type="text/javascript">f()</script>

//pause and resume buttons would go here.
</body>

    You can stop a timeout with clearTimeout() passing it the return from setTimeout or, in your case t.

    Live example: http://jsfiddle.net/tJWmH/

    Another pointer: dont pass a string to setTimeout, instead pass a function reference, so:

    var t = setTimeout(f,1000)

    in place of

    var t = setTimeout("f()",1000);

    if you’re wondering why, search for “eval is evil”.
