javascript to reset html page during work hours.

I have this (cited from another post on Experts-Exchange) but it does nothing.

<script type="text/javascript">
//60000 milliseconds is 1 minute
window.setInterval("checkForRefresh()", 600);

function checkForRefresh() {
   var now = new Date();
   if (now.getHours() >= 7) {
    window.refresh();
   }
}
</script>

I'm using this snippet

function refreshAt(hours, minutes, seconds) {
    var now = new Date();
    var then = new Date();

    if(now.getHours() > hours ||
       (now.getHours() == hours && now.getMinutes() > minutes) ||
        now.getHours() == hours && now.getMinutes() == minutes && now.getSeconds() >= seconds) {
        then.setDate(now.getDate() + 1);
    }
    then.setHours(hours);
    then.setMinutes(minutes);
    then.setSeconds(seconds);

    var timeout = (then.getTime() - now.getTime());
    setTimeout(function() { window.location.reload(true); }, timeout);
}

refreshAt(9,33,0); //Will refresh the page at 9:33

Open in new window

With the current code if you're using 60000 milliseconds your code will remain refreshing from 08:00 until 23:59 but you need to use :

location.reload();

Open in new window


Instead of :

window.refresh();

Open in new window

That worked to refresh at a specific time, but not during work hours.  and since the refreshAt is set specifically, I don't see how it can be altered accordingly ?

You need to refresh to which frequency?

Yes, I should have been clearer. I want the page to refresh every x seconds, but only drying work hours, specifically 8am to 5pm.

This worked. Thanks to all

//60000 milliseconds is 1 minute
window.setInterval("checkForRefresh()", 60000);

function checkForRefresh() {
   var now = new Date();
   if (now.getHours() >= 7 && now.getHours() <= 18) {
    location.reload();
   }
}

Then you need just to add a condition to your current one like :

if (now.getHours() > 7 && now.getHours() < 17) {
    window.refresh();
 }

Good job you find it.

specifically 8am to 5pm.

Just as a side note , your current condition :
if (now.getHours() >= 7 && now.getHours() <= 18) {

Open in new window


Will include 7am and 6pm , be careful. If you want to exclude them check my previous comment...
