Hi all...


<form name="myForm">
<input name="myCheckBox" type="checkbox">
<input name="totalTime" type="text">
</form>

<script language="JavaScript">
function timer() {
if (document.myForm.myCheckBox.checked != isitchecked) {
// checkbox clicked
isitchecked = document.myForm.myCheckBox.checked;
now = new Date()
if (isitchecked)
starttime = now.getTime(); // now checked so reset starttime
else
document.myForm.totalTime.value = 0; // no longer checked so reset
}
else {
// not clicked since last check
if (isitchecked) {
// still checked
now = new Date();
totaltime = now.getTime() - starttime; // totaltime in milliseconds that checkbox has been checked.
document.myForm.totalTime.value = totaltime/1000/60; // time in minutes
}
}
setTimeout('timer()',100);
}

var totaltime = 0;

document.myForm.totalTime.value = totaltime;

var isitchecked = document.myForm.myCheckBox.checked;

if (isitchecked) {
now = new Date()
starttime = now.getTime(); // if intial stae is check then set starttime
}

timer(); // start constant monitoring of checkbox
</script>

Thanks...
