Right. Kudos to Genesis for thinking of using scripting. That hadn't occurred to me and writing a full program would take significantly longer.
Failed attempt. It turns out that all intervals are cleared when a page is reloaded. I will try again, with the use of frames.
» Click to show Spoiler - click again to hide... «
To refresh the page once every 10 seconds, put this in the URL bar, and press Enter:
CODE
javascript: var refresherIndex = window.setInterval("location.reload(true)", 10000); void(0);
To stop the refreshing, use this script:
CODE
javascript: window.clearInterval(refresherIndex);
New attempt:
» Click to show Spoiler - click again to hide... «
Put this script in the URL bar:
CODE
javascript: document.write('<button id="stop" onclick="if (going) window.clearInterval(refresherIndex); going = false;">Stop</button><button id="start" onclick="if (!going) start();">Start</button><br /><iframe id="framey" width="700" height="500"></iframe><script type="text/javascript">var refresherIndex; var going; function start() {going = true; var theURL = window.prompt("What page to refresh?"); if (theURL.substring(0, 7) != "http://") theURL = "http://" + theURL; window.frames[0].location.href=theURL; refresherIndex = window.setInterval("window.frames[0].location.reload(true);", 10000);} start();</script>');
