  1. POHow to keep refreshing the page periodically while the user is away from the page? and not to refresh if on the page
    text
    copied!<p>Is it possible to refresh a webpage, say, every minute when the user is NOT on the page? For example, if I am visiting a PageX and stay on the page it doesn't refresh but as soon as I navigate away from the page (that is, switch to another tab/window or a program, then the PageX refreshes every x minutes or seconds? How do I go about this? Thx.</p> <p><strong>Update:</strong></p> <p>"on the page" means the page is the current window i.e. it has focus. So if the PageX has a link to a pop window, say 100 x 100, clicking that opens the popup, while the page is still kind of visible behind that tiny popup window, it doesn't have a focus, hence needs refresh as stated above.</p> <p>Any thing not clear please ask.</p> <p><strong>Update 2</strong></p> <p>As suggested by Mattk below .. Following seems to be working in Firefox (haven't checked in the latest), and Chrome. In the IE 8, if I switch to another tab or a program, it doesnt' refresh the page, but if I am on the page and click in the address bar, it starts refreshing the page. Any ideas how to get it working in IE?</p> <pre><code>var pageFocused = false; function onPageFocus(){ pageFocused = true; //document.body.className = 'focused'; } function onPageBlur() { pageFocused = false; //document.body.className = 'blurred'; }; function checkActivity() { if(pageFocused == false){ location.reload(true); } } setInterval("checkActivity()", 1 * 1000); if (!+"\v1") { // check for Internet Explorer document.onfocusin = onPageFocus; document.onfocusout = onPageBlur; } else if (/*@cc_on!@*/false) { document.onfocusin = onPageFocus; document.onfocusout = onPageBlur; } else { window.onfocus = onPageFocus; window.onblur = onPageBlur; } </code></pre>
