If you want to refresh the page if there is no activity then you need to figure out how to define activity. Let's say we refresh the page every minute unless someone presses a key or moves the mouse. This uses jQuery for event binding:
<script>
var time = new Date().getTime();
$(document.body).bind("mousemove keypress", function(e) {
time = new Date().getTime();
});
function refresh() {
if(new Date().getTime() - time >= 60000)
window.location.reload(true);
else
setTimeout(refresh, 10000);
}
setTimeout(refresh, 10000);
</script>

I have built a complete javascript solution as well that does not require jquery. Might be able to turn it into a plugin. I use it for fluid auto-refreshing, but it looks like it could help you here.
// Refresh Rate is how often you want to refresh the page
// bassed off the user inactivity.
var refresh_rate = 200; //<-- In seconds, change to your needs
var last_user_action = 0;
var has_focus = false;
var lost_focus_count = 0;
// If the user loses focus on the browser to many times
// we want to refresh anyway even if they are typing.
// This is so we don't get the browser locked into
// a state where the refresh never happens.
var focus_margin = 10;
// Reset the Timer on users last action
function reset() {
last_user_action = 0;
console.log("Reset");
}
function windowHasFocus() {
has_focus = true;
}
function windowLostFocus() {
has_focus = false;
lost_focus_count++;
console.log(lost_focus_count + " <~ Lost Focus");
}
// Count Down that executes ever second
setInterval(function () {
last_user_action++;
refreshCheck();
}, 1000);
// The code that checks if the window needs to reload
function refreshCheck() {
var focus = window.onfocus;
if ((last_user_action >= refresh_rate && !has_focus && document.readyState == "complete") || lost_focus_count > focus_margin) {
window.location.reload(); // If this is called no reset is needed
reset(); // We want to reset just to make sure the location reload is not called.
}
}
window.addEventListener("focus", windowHasFocus, false);
window.addEventListener("blur", windowLostFocus, false);
window.addEventListener("click", reset, false);
window.addEventListener("mousemove", reset, false);
window.addEventListener("keypress", reset, false);
window.addEventListener("scroll", reset, false);
document.addEventListener("touchMove", reset, false);
document.addEventListener("touchEnd", reset, false);

<script type="text/javascript">
var timeout = setTimeout("location.reload(true);",600000);
function resetTimeout() {
clearTimeout(timeout);
timeout = setTimeout("location.reload(true);",600000);
}
</script>
Above will refresh the page every 10 minutes unless resetTimeout() is called. For example:
<a href="javascript:;" onclick="resetTimeout();">clicky</a>

Based on the accepted answer of arturnt. This is a slightly optimized version, but does essentially the same thing:
var time = new Date().getTime();
$(document.body).bind("mousemove keypress", function () {
time = new Date().getTime();
});
setInterval(function() {
if (new Date().getTime() - time >= 60000) {
window.location.reload(true);
}
}, 1000);
Only difference is that this version uses setInterval instead of setTimeout, which makes the code more compact.

var bd = document.getElementsByTagName('body')[0];
var time = new Date().getTime();
bd.onmousemove = goLoad;
function goLoad() {
if(new Date().getTime() - time >= 1200000) {
time = new Date().getTime();
window.location.reload(true);
}else{
time = new Date().getTime();
}
}
Each time you move the mouse it will check the last time you moved the mouse. If the time interval is greater than 20' it will reload the page, else it will renew the last-time-you-moved-the-mouse.

Auto reload with target of your choice. In this case target is _self set to itself,but you could change the reload page by simply changing the window.open('self.location', '_self'); code to something like this examplewindow.top.location="window.open('http://www.YourPageAdress.com', '_self'";.
With a confirmation ALERT message:
<script language="JavaScript">
function set_interval() {
//the interval 'timer' is set as soon as the page loads
var timeoutMins = 1000 * 1 * 15; // 15 seconds
var timeout1Mins = 1000 * 1 * 13; // 13 seconds
itimer=setInterval("auto_logout()",timeoutMins);
atimer=setInterval("alert_idle()",timeout1Mins);
}
function reset_interval() {
var timeoutMins = 1000 * 1 * 15; // 15 seconds
var timeout1Mins = 1000 * 1 * 13; // 13 seconds
//resets the timer. The timer is reset on each of the below events:
// 1. mousemove 2. mouseclick 3. key press 4. scrolling
//first step: clear the existing timer
clearInterval(itimer);
clearInterval(atimer);
//second step: implement the timer again
itimer=setInterval("auto_logout()",timeoutMins);
atimer=setInterval("alert_idle()",timeout1Mins);
}
function alert_idle() {
var answer = confirm("Session About To Timeout\n\n You will be automatically logged out.\n Confirm to remain logged in.")
if (answer){
reset_interval();
}
else{
auto_logout();
}
}
function auto_logout() {
//this function will redirect the user to the logout script
window.open('self.location', '_self');
}
</script>
Without confirmation alert:
<script language="JavaScript">
function set_interval() {
//the interval 'timer' is set as soon as the page loads
var timeoutMins = 1000 * 1 * 15; // 15 seconds
var timeout1Mins = 1000 * 1 * 13; // 13 seconds
itimer=setInterval("auto_logout()",timeoutMins);
}
function reset_interval() {
var timeoutMins = 1000 * 1 * 15; // 15 seconds
var timeout1Mins = 1000 * 1 * 13; // 13 seconds
//resets the timer. The timer is reset on each of the below events:
// 1. mousemove 2. mouseclick 3. key press 4. scrolling
//first step: clear the existing timer
clearInterval(itimer);
clearInterval(atimer);
//second step: implement the timer again
itimer=setInterval("auto_logout()",timeoutMins);
}
function auto_logout() {
//this function will redirect the user to the logout script
window.open('self.location', '_self');
}
</script>
Body code is the SAME for both solutions:
<body onLoad="set_interval(); document.form1.exp_dat.focus();" onKeyPress="reset_interval();" onmousemove="reset_interval();" onclick="reset_interval();" onscroll="reset_interval();">

Yes dear,then you have to use Ajax technology. to changes contents of particular html tag:
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<title>Ajax Page</title>
<script>
setInterval(function () { autoloadpage(); }, 30000); // it will call the function autoload() after each 30 seconds.
function autoloadpage() {
$.ajax({
url: "URL of the destination page",
type: "POST",
success: function(data) {
$("div#wrapper").html(data); // here the wrapper is main div
}
});
}
</script>
</head>
<body>
<div id="wrapper">
contents will be changed automatically.
</div>
</body>
</html>

I would consider activity to be whether or not the user is focused on the window. For example, when you click from one window to another (e.g. Google Chrome to iTunes, or Tab 1 to Tab 2 within an internet browser), the webpage can send a callback saying "Im out of focus!" or "Im in focus!". One could use jQuery to harness this possible lack of activity to do whatever they wanted. If I were in your position, I would use the following code to check for focus every 5 seconds, etc and reload if no focus.
var window_focus;
$(window).focus(function() {
window_focus = true;
}).blur(function() {
window_focus = false;
});
function checkReload(){
if(!window_focus){
location.reload(); // if not focused, reload
}
}
setInterval(checkReload, 5000); // check if not focused, every 5 seconds

And finally the most simple solution:
With alert confirmation:
<script type="text/javascript">
// Set timeout variables.
var timoutWarning = 3000; // Display warning in 1Mins.
var timoutNow = 4000; // Timeout in 2 mins.
var warningTimer;
var timeoutTimer;
// Start timers.
function StartTimers() {
warningTimer = setTimeout("IdleWarning()", timoutWarning);
timeoutTimer = setTimeout("IdleTimeout()", timoutNow);
}
// Reset timers.
function ResetTimers() {
clearTimeout(warningTimer);
clearTimeout(timeoutTimer);
StartTimers();
$("#timeout").dialog('close');
}
// Show idle timeout warning dialog.
function IdleWarning() {
var answer = confirm("Session About To Timeout\n\n You will be automatically logged out.\n Confirm to remain logged in.")
if (answer){
ResetTimers();
}
else{
IdleTimeout();
}
}
// Logout the user and auto reload or use this window.open('http://www.YourPageAdress.com', '_self'); to auto load a page.
function IdleTimeout() {
window.open(self.location,'_top');
}
</script>
Without alert confirmation:
<script type="text/javascript">
// Set timeout variables.
var timoutWarning = 3000; // Display warning in 1Mins.
var timoutNow = 4000; // Timeout in 2 mins.
var warningTimer;
var timeoutTimer;
// Start timers.
function StartTimers() {
warningTimer = setTimeout(timoutWarning);
timeoutTimer = setTimeout("IdleTimeout()", timoutNow);
}
// Reset timers.
function ResetTimers() {
clearTimeout(warningTimer);
clearTimeout(timeoutTimer);
StartTimers();
$("#timeout").dialog('close');
}
// Logout the user and auto reload or use this window.open('http://www.YourPageAdress.com', '_self'); to auto load a page.
function IdleTimeout() {
window.open(self.location,'_top');
}
</script>
Body code is the SAME for both solutions
<body onload="StartTimers();" onmousemove="ResetTimers();" onKeyPress="ResetTimers();">

With on page confirmation text instead of alert
Since this is another method to auto load if inactive I give it a second answer. This one is more simple and easier to understand.
With reload confirmation on the page
<script language="javaScript" type="text/javascript">
<!--
var autoCloseTimer;
var timeoutObject;
var timePeriod = 5100; // 5,1 seconds
var warnPeriod = 5000; // 5 seconds
// Warning period should always be a bit shorter then time period
function promptForClose() {
autoCloseDiv.style.display = 'block';
autoCloseTimer = setTimeout("definitelyClose()", warnPeriod);
}
function autoClose() {
autoCloseDiv.style.display = 'block'; //shows message on page
autoCloseTimer = setTimeout("definitelyClose()", timePeriod); //starts countdown to closure
}
function cancelClose() {
clearTimeout(autoCloseTimer); //stops auto-close timer
autoCloseDiv.style.display = 'none'; //hides message
}
function resetTimeout() {
clearTimeout(timeoutObject); //stops timer
timeoutObject = setTimeout("promptForClose()", timePeriod); //restarts timer from 0
}
function definitelyClose() {
// If you use want targeted reload: parent.Iframe0.location.href = "https://URLHERE.com/"
// or this: window.open('http://www.YourPageAdress.com', '_self');
// of for the same page reload use: window.top.location=self.location;
// or window.open(self.location;, '_self');
window.top.location=self.location;
}
-->
</script>
Confirmation box when using with on page confirmation
<div class="leftcolNon">
<div id='autoCloseDiv' style="display:none">
<center>
<b>Inactivity warning!</b><br />
This page will Reloads automatically unless you hit 'Cancel.'</p>
<input type='button' value='Load' onclick='definitelyClose();' />
<input type='button' value='Cancel' onclick='cancelClose();' />
</center>
</div>
</div>
Body codes for both are the SAME
<body onmousedown="resetTimeout();" onmouseup="resetTimeout();" onmousemove="resetTimeout();" onkeydown="resetTimeout();" onload="timeoutObject=setTimeout('promptForClose()',timePeriod);">
NOTE: If you do not want to have the on page confirmation, use Without confirmation
<script language="javaScript" type="text/javascript">
<!--
var autoCloseTimer;
var timeoutObject;
var timePeriod = 5000; // 5 seconds
function resetTimeout() {
clearTimeout(timeoutObject); //stops timer
timeoutObject = setTimeout("definitelyClose()", timePeriod); //restarts timer from 0
}
function definitelyClose() {
// If you use want targeted reload: parent.Iframe0.location.href = "https://URLHERE.com/"
// or this: window.open('http://www.YourPageAdress.com', '_self');
// of for the same page reload use: window.top.location=self.location;
// or window.open(self.location;, '_self');
window.top.location=self.location;
}
-->
</script>

Using LocalStorage to keep track of the last time of activity, we can write the reload function as follows
function reloadPage(expiryDurationMins) {
const lastInteraction = window.localStorage.getItem('lastinteraction')
if (!lastInteraction) return // no interaction recorded since page load
const inactiveDurationMins = (Date.now() - Number(lastInteraction)) / 60000
const pageExpired = inactiveDurationMins >= expiryDurationMins
if (pageExpired) window.location.reload()
}
Then we create an arrow function which saves the last time of interaction in milliseconds(String)
const saveLastInteraction = () => window.localStorage.setItem('last', Date.now().toString())
We will need to listen to the beforeunload event in the browser to clear our lastinteraction record so we don't get stuck in an infinite reload loop.
window.addEventListener('beforeunload', () => window.localStorage.removeItem('lastinteraction'))
The user activity events we will need to monitor would be mousemove and keypress. We store the last interaction time when the user moves the mouse or presses a key on the keyboard
window.addEventListener('mousemove', saveLastInteraction)
window.addEventListener('keypress', saveLastInteraction)
To set up our final listener, we will use the load event.
On page load, we use the setInterval function to check if the page has expired after a certain period.
const expiryDurationMins = 1
window.addEventListener('load', setInterval.bind(null, reloadPage.bind(null, expiryDurationMins), 1000))

I am doing it like this:
let lastActionTaken = new Date().getTime();
function checkLastAction() {
let now = new Date().getTime();
if (now - lastActionTaken > 1000 * 60 * 60) window.location.reload();
else lastActionTaken = now;
}
window.addEventListener("mousemove", checkLastAction);
window.addEventListener("touchstart", checkLastAction);
window.addEventListener("keydown", checkLastAction);
This will reload the page as soon as the user moves their mouse, hits a key or touches a touchscreen if it has been inactive for 1 hour. Also, this takes care of the focus as well, so if a user is moving their mouse in a different program and then come back to this window it will reload, which is good because the point is to not have old data being shown.
