javascript increment setInteval counter while video is playing - javascript

I have the following code that detect if user is idle or not. On page load, a timer will run and if the user is idle for a certain of seconds the timer will pause and resume if the user is active. And I have also codes that detect if video is playing, if the video is playing timer should run and if the video is stop/pause a timeout will run and detect if the user is still active
The problem is even if video is playing, the timer paused and it will start to idle. What I want is when video is playing timer should countinue to increment.
Heres my code:
function setPlayingVideoToTrue(){playing_video = true;}
function setPlayingVideoToFalse(){playing_video = false;}
// check if a video iframe exists
var iframe_videos = $('body').find('iframe');
if(iframe_videos.length > 0){
// create ready events for every iframe
iframe_videos.each(function(index){
// add a temporary id for the iframe
// append additional parameters to the end of the iframe's src
var temporary_player_id = 'iframe_player_'+ index;
var new_iframe_src = $(this).attr('src') +'?api=1&player_id='+ temporary_player_id;
$(this).attr('id', temporary_player_id);
$(this).attr('src', new_iframe_src);
// add event listener for ready
$f(this).addEvent('ready', iframe_ready);
});
// when a player is ready, add event listeners for play, pause, finish, and playProgress
function iframe_ready(player_id) {
$f(player_id).addEvent('play', setPlayingVideoToTrue);
$f(player_id).addEvent('playProgress', setPlayingVideoToTrue);
$f(player_id).addEvent('pause', setPlayingVideoToFalse);
$f(player_id).addEvent('finish', setPlayingVideoToFalse);
}
}
function start_idle_timer(){
var timer = 0;
function increment_duration()
{
if(isPaused === false)
{
timer++;
}
// increment timer if video is playing
if(playing_video === true){
clearTimeout(idleTimer);
isPaused = false;
}
if(playing_video === false && isPaused === false){
// stop timer if the user is idle for 3 minutes
var idleTimer = setTimeout(function(){
// console.log('idle');
clearInterval(check_time);
isPaused = true;
// a modal will apper to inform that user is on idle state
$('#linkage').trigger('click');
var modal_timer = 0;
// timer for modal idle timer
continue_modal_timer = setInterval(function(){
modal_timer++;
inactivity_timer = modal_timer;
if(modal_timer == 60)
{
clearInterval(continue_modal_timer);
clearTimeout(idleTimer);
}
}, 1000)
}, 10000);
}
// bind to all elements on DOM possible events indicating the user is active
$('*').bind('mousemove click mouseup mousedown keydown keypress keyup submit change mouseenter scroll resize dblclick', function () {
clearTimeout(idleTimer);
isPaused = false;
});
}
// initialize the interval
check_time = setInterval(increment_duration, 1000);
}
// check if start_timer is present from the loading page to record the time duration of the user
if($('.start_timer').length > 0){
start_idle_timer();
}

addEventListener to no action?

I would like a modal to pop up if there has been no action on the page by the user for the last 3 seconds. Is there a way for addEventListener to run a function upon no action for 3 seconds?
Use setTimeout() to open the modal after 3 seconds and use an event listener for key presses (or key up, etc) to reset the timeout.
let timeout = undefined;
function resetTimer() {
if (timeout) {
clearTimeout(timeout);
}
timeout = setTimeout(function() {
// open modal, call resetTimer() when it is closed to restart the check...
/*
modal.onClose = resetTimer;
modal.open();
*/
console.log('open modal');
}, 3000);
}
window.onload = function() {
// every time a key is pressed reset the timer
document.addEventListener('keypress', resetTimer);
// start the timer
resetTimer();
};

Reset timer on mousemove and keypress

The below javascript code auto refresh the page every 10 sec.
My question is how can I reset the timer on mousemove and keypress.
Java-Script
<script type="text/javascript" language="JavaScript">
var secs;
var timerID = null;
var timerRunning = false;
var delay = 1000;
function InitializeTimer(seconds) {
//length of the timer, in seconds
secs = seconds;
StopTheClock();
StartTheTimer();
}
function StopTheClock() {
if (timerRunning)
clearTimeout(timerID);
timerRunning = false;
}
function StartTheTimer() {
if (secs == 0) {
StopTheClock();
window.location.href = window.location.href;
}
else {
document.getElementById("lbltime").innerText = secs + " ";
secs = secs - 1;
timerRunning = true;
timerID = self.setTimeout("StartTheTimer()", delay);
}
}
</script>
Thank you in advance.
If I understood you correctly, something like this (really basic example: the timer is reset on mousemove and keypress):
var elem = document.getElementById("timer"), timeout, startTimer = function timer() {
elem.textContent++;
timeout = setTimeout(timer, 1000)
}
function resetTimer() {
// here you reset the timer...
clearTimeout(timeout);
elem.textContent = -1;
startTimer();
//... and also you could start again some other action
}
document.addEventListener("mousemove", resetTimer);
document.addEventListener("keypress", resetTimer);
startTimer();
<span id="timer">-1</span> - Move cursor or press a key to reset timer.
As I guess, you want to delay page reloading if there was some user activity on the page. In your reload() function you just need to check, if timer's value reached the limit (like 60 seconds). If yes, execute reloading. However, notice, that handling mousemove event can make browser's tab have high CPU usage, if, for example, I just start to move my cursor quickly. You might want to pick some important areas and set handlers on the corresponding elements. For example, keypress event can be listened to only on a comment form or mousemove can be listened to only on a menu or on an article.
PS. Also take into account that
The keypress event is fired when a key is pressed down, and that key normally produces a character value
so, if user presses, for example, ctrl or alt the event will not be fired.
Your code seems a bit too branched out in my opinion, what I would do is simplify it a bit.
window.refreshTimeout = null;
function refreshPage(){
location.reload();
}
function refresh(){
clearTimeout(window.refreshTiemout);
window.refreshTimeout = setTimeout(refreshPage, 2000)
}
window.refreshTimeout = setTimeout(refreshPage, 2000)
window.addEventListener('mousemove', refresh)
<h4>HelloWorld</h4>
As you can see, you attach an event listener to the window for a mouse move (you can attach others too) within which you cancel the previous timeout and start a new one. Initially you of course start a timeout.

Stop video play when leaving a jquery mobile page

So I have a jquery mobile page with an html 5 video in it and that I want to be able to either stop playing and reset its self or just automatically pause the video. Would this be the correct javascript?
<script>
function restart() {
var video = document.getElementById("Video1");
video.currentTime = 0;}
if ($.mobile.activePage.attr('id') != 'a28') { "restart"}
</script>
have you tried the pagehide , it gets called when the current active page gets hide / changed.
$(function(){
$('#a28').live('pagehide',function(){
//stop the video
});
});
Make use of a loop, to check if the user is on the webpage. Store the time.
var lastSeen;
var loop = function (){
lastSeen = Date.now();
setTimeout(loop, 50);
};
loop();
var video = document.getElementById('Video1');
video.addEventListener('timeupdate', function (){
if(Date.now() - lastSeen > 100){
this.pause();
}
}, false);

How can I make a timer start & work only when onFocus is true?

I have this timer (see Code below). How can I make sure that the countdown starts AND keeps counting down only if the browser window is onFocus?
(I want it to pause if the user opens another window, for example.)
//Countdown
function timerCountdown()
{
x=100;
document.getElementById('timer1').value=x;
x=x-1;
t=setTimeout("timerCountdown()",1000);
if (c<-1)
{
document.getElementById('timer1').value='Go';
clearTimeout(t);
}
}
window.onblur = function() {
// Stop counting
}
window.onfocus = function() {
// Start counting
}

How to automatically reload a page after a given period of inactivity

How can I automatically reload a webpage, if there have been no activity on the page for a given period of time?
This can be accomplished without javascript, with this metatag:
<meta http-equiv="refresh" content="5" >
where content ="5" are the seconds that the page will wait until refreshed.
But you said only if there was no activity, what kind for activity would that be?
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.
JSFiddle AutoRefresh
// 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:
clicky
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.
use JavaScript setInterval method:
setInterval(function(){ location.reload(); }, 3000);
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'";.

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.
Many of these other answers either don't answer the main part of the question "with no activity", or they are incredibly, unnecessarily complex. I have taken the accepted answer (here: https://stackoverflow.com/a/4644315/9008140 )
and modified it to take advantage of the fact you can assign timers to variables. This allows us to get rid of the second timer, as well as the timestamp.
/**
* create a timer that refreshes the page after the number of
minutes has passed without user interaction.
* Moving the mouse or pressing a key on the current page will start
the timer over.
* #param {any} minutes
*/
var refreshTimer;
function setPageRefreshTimer(minutes) {
var refreshInterval = minutes * 60 * 1000; //interval is in milliseconds. We refresh every x minutes.
$(document.body).bind("mousemove keypress", function (e) {
if (refreshTimer != null && refreshTimer != undefined) {
window.clearTimeout(refreshTimer);
}
refreshTimer = window.setTimeout(function () { window.location.reload(true); }, refreshInterval);
});
refreshTimer = window.setTimeout(function () { window.location.reload(true); }, refreshInterval);
}
This sample code will refresh based on a passed in parameter in minutes, with an accuracy as great as a javascript timer can be. In testing, always less than a second. I created this as a function but you can pull it into your page if you wish.
This task is very easy use following code in html header section
<head> <meta http-equiv="refresh" content="30" /> </head>
It will refresh your page after 30 seconds.
