jQuery Callback Function Timer

[mathceleb]

I want to create a function in jQuery that is a continous timer that calls itself every second:

I'm getting an error undefined values:

var curloc=window.location.href;
var tcorner="gtype=T";
curpos=curloc.indexOf(tcorner);
// teachers corner clock
if (curloc.indexOf("gtype=T")>-1){
h=0;
m=0;
s=0;
window.setInterval(function(h,m,s) {
//temptime=startclock(h,m,s).split("_");
//h=temptime[0];
//m=temptime[1];
//s=temptime[2];

s=s+1;
if (s==60){
s=0;
m=m+1;
}

if (m==60){
m=0;
h=h+1;
}
else{
h=h;
}

// leading zero
ds=s;
if (s<10) {ds="0" + s;}

dm=m;

if (h==0){
dh="";
}
else{
dh=h;
}

$(".visibleDiv").html(dh+" "+dm+":"+ds); 
}, 1000);

}

I was able to get this to work calling an external function.

However, if there is a way to do it within itself passing the values to itself, I'd like to know.
