Updating Javascript

Question
I'm trying to create an updating clock in Javascript. Everything is working correctly as I step through the debugger, except that it's not actually updating the span. Any ideas why?
<script type="text/javascript">
// The following line of code is in a setInterval()
// time is set correctly, according to my debugger
document.getElementById('clock').value = time;
}
</script>
<span id="clock">This should update
</span>
Solution
Change value
to innerHTML
document.getElementById('clock').innerHTML = time;
value
is only a valid attribute for form elements like input
or option
.
OTHER TIPS
Also, to have it refresh (if you are doing a clock), use window.setTimeout;
window.setTimeout(function() { document.getElementById('clock').innerHTML = 'XYZ'; }, 500);
500 is millisecond value.
