wilna Posted October 14, 2011 Share Posted October 14, 2011 Hi, please excuse my lack of knowledge. I've got a JavaScript clock on my page. My problem is when the users refreshes my php page the clock starts from 0 again. I need the clock to remember the value and then just continue from where it was. I've been trying with cookies but gave up. Can someone please help me? I've been trying but I'm clueless. Javascript var pageVisisted = new Date(); setInterval(function() { var timeOnSite = new Date() - pageVisisted; var secondsTotal = timeOnSite / 1000; var hours = Math.floor(secondsTotal / 3600); var minutes = Math.floor(secondsTotal / 60) % 3600; var seconds = Math.floor(secondsTotal) % 60; document.getElementById('counter').innerHTML = hours + ":" + minutes + ":" + seconds; }, 1000); The php page <head> <?php session_start(); ?> <script type="text/javascript" src="counter.js"></script> </head> <body> <?php echo "<span id='counter'></span>"; ?> </body> Link to comment https://forums.phpfreaks.com/topic/249112-javascript-clock-on-refresh/ Share on other sites More sharing options...
