A page has a long running computation loop.
While in the loop I want to update a status object so I know how
things are going in the computation.
This is what I have, but it doesn't seem to update my status object.
Thanks,
Richard

<script type="text/javascript">
function compute() {
var status = document.getElementById ('status')
var result = document.getElementById ('result')
var j = 0;
var n = 1e6;
var p = n/10;
// tight loop
for (var i=0;i<n;i++) {
// if (j++ > p) { j=0; status.value = i; }
if (j++ > p) { j=0; setTimeout ( function(){status.value=i} , 1) }
}
setTimeout ( function(){status.value='Compute'} , 1)
result.innerHTML = "Computation results " + i
return false
}

<input id=status type=submit value='Compute'
