If you aren't already, I recommend putting to use a JS library with Ajax support. Nothing else, they can reduce the browser compatibility overhead coding you'll need to do. You can pick any of many, but I'm more familiar with Prototype: http://prototypejs.org/ ## credits.php -------------------- <?php /* ... */ // determine value for $credits print min($credits, 0); ?> ## credits.html --------------------- <html> <body> <div id="credits">Checking credits...</div> <script src="prototype.js"></script> <script type="text/javascript"> /*** Reference ***/ //// http://prototypejs.org/api/periodicalExecuter //// http://prototypejs.org/api/ajax/request //// http://prototypejs.org/api/element/observe function creditsCheck(pe) { new Ajax.Request('foobar.php', { method: 'get', parameters: {ts: (new Date()).getTime()}, // cache prevention onSuccess: function (transport) { var elem = $('credits'); if (Number(transport.responseText) > 0) { elem.update('Credits remaining: ' + transport.responseText); } else { elem.update('Credits have expired.').setStyle({background: '#f00'}); pe.stop(); } }, onFailure: function () { $('credits').update('Could not determine credits.').setStyle({background: '#f00'}); } }); } document.observe('dom:loaded', function () { var pe = new PeriodicalExecuter(creditsCheck, 60); creditsCheck(pe); // first check }); </script> </body> </html> - Jon L.
