Stop timer in jQuery and JS

I need to stop timer when popup is active.
I have two popups where it works. But it doesn't work with first one which is automatic when the page is on.
// Calling function - this is in popup.html
var popUp1 = false;
var popUp2 = false;
// Calling function with instruction by click
function togglePopup(){
popUp1 = document.getElementById("popup-1").classList.toggle("active");
timeToggle()
}
// Calling function with description by click
function myFunction(){
popUp2 = document.getElementById("desc").classList.toggle("activeD");
timeToggle()
}
// function for pausing game when there is popUp
function timeToggle(){
if (!popUp1 && !popUp2){
Init();
}else{
clearInterval(moveItIntervalID); //stopping time and random images
clearInterval(timeIntervalID);
}
}
//here is funcion with automatic popup
$( document ).ready(function() {
$('#descS').bPopup();
timeToggle()
(function(c){c.fn.bPopup=function(A,E){function L(){a.contentContainer=c(a.contentContainer||b);switch(a.content){case "iframe":var d=c('<iframe class="b-iframe" '+a.iframeAttr+"></iframe>");d.appendTo(a.contentContainer);t=b.outerHeight(!0);u=b.outerWidth(!0);B();d.attr("src",a.loadUrl);l(a.loadCallback);break;case "image":B();c("<img />").load(function(){l(a.loadCallback);F(c(this))}).attr("src",a.loadUrl).hide().appendTo(a.contentContainer);break;default:B(),c('<div class="b-ajax-wrapper"></div>').load(a.loadUrl,a.loadData,function(d,b,e){l(a.loadCallback,b);F(c(this))}).hide().appendTo(a.contentContainer)}}function B(){a.modal&&c('<div class="b-modal '+e+'"></div>').css({backgroundColor:a.modalColor,position:"fixed",top:0,right:0,bottom:0,left:0,opacity:0,zIndex:a.zIndex+v}).appendTo(a.appendTo).fadeTo(a.speed,a.opacity);C();b.data("bPopup",a).data("id",e).css({left:"slideIn"==a.transition||"slideBack"==a.transition?"slideBack"==a.transition?f.scrollLeft()+w:-1*(x+u):m(!(!a.follow[0]&&n||g)),position:a.positionStyle||"absolute",top:"slideDown"==a.transition||"slideUp"==a.transition?"slideUp"==a.transition?f.scrollTop()+y:z+-1*t:p(!(!a.follow[1]&&q||g)),"z-index":a.zIndex+v+1}).each(function(){a.appending&&c(this).appendTo(a.appendTo)});G(!0)}function r(){a.modal&&c(".b-modal."+b.data("id")).fadeTo(a.speed,0,function(){c(this).remove()});a.scrollBar||c("html").css("overflow","auto");c(".b-modal."+e).unbind("click");f.unbind("keydown."+e);k.unbind("."+e).data("bPopup",0<k.data("bPopup")-1?k.data("bPopup")-1:null);b.undelegate(".bClose, ."+a.closeClass,"click."+e,r).data("bPopup",null);clearTimeout(H);G();return!1}function I(d){y=k.height();w=k.width();h=D();if(h.x||h.y)clearTimeout(J),J=setTimeout(function(){C();d=d||a.followSpeed;var e={};h.x&&(e.left=a.follow[0]?m(!0):"auto");h.y&&(e.top=a.follow[1]?p(!0):"auto");b.dequeue().each(function(){g?c(this).css({left:x,top:z}):c(this).animate(e,d,a.followEasing)})},50)}function F(d){var c=d.width(),e=d.height(),f={};a.contentContainer.css({height:e,width:c});e>=b.height()&&(f.height=b.height());c>=b.width()&&(f.width=b.width());t=b.outerHeight(!0);u=b.outerWidth(!0);C();a.contentContainer.css({height:"auto",width:"auto"});f.left=m(!(!a.follow[0]&&n||g));f.top=p(!(!a.follow[1]&&q||g));b.animate(f,250,function(){d.show();h=D()})}function M(){k.data("bPopup",v);b.delegate(".bClose, ."+a.closeClass,"click."+e,r);a.modalClose&&c(".b-modal."+e).css("cursor","pointer").bind("click",r);N||!a.follow[0]&&!a.follow[1]||k.bind("scroll."+e,function(){if(h.x||h.y){var d={};h.x&&(d.left=a.follow[0]?m(!g):"auto");h.y&&(d.top=a.follow[1]?p(!g):"auto");b.dequeue().animate(d,a.followSpeed,a.followEasing)}}).bind("resize."+e,function(){I()});a.escClose&&f.bind("keydown."+e,function(a){27==a.which&&r()})}function G(d){function c(e){b.css({display:"block",opacity:1}).animate(e,a.speed,a.easing,function(){K(d)})}switch(d?a.transition:a.transitionClose||a.transition){case "slideIn":c({left:d?m(!(!a.follow[0]&&n||g)):f.scrollLeft()-(u||b.outerWidth(!0))-200});break;case "slideBack":c({left:d?m(!(!a.follow[0]&&n||g)):f.scrollLeft()+w+200});break;case "slideDown":c({top:d?p(!(!a.follow[1]&&q||g)):f.scrollTop()-(t||b.outerHeight(!0))-200});break;case "slideUp":c({top:d?p(!(!a.follow[1]&&q||g)):f.scrollTop()+y+200});break;default:b.stop().fadeTo(a.speed,d?1:0,function(){K(d)})}}function K(d){d?(M(),l(E),a.autoClose&&(H=setTimeout(r,a.autoClose))):(b.hide(),l(a.onClose),a.loadUrl&&(a.contentContainer.empty(),b.css({height:"auto",width:"auto"})))}function m(a){return a?x+f.scrollLeft():x}function p(a){return a?z+f.scrollTop():z}function l(a,e){c.isFunction(a)&&a.call(b,e)}function C(){z=q?a.position[1]:Math.max(0,(y-b.outerHeight(!0))/2-a.amsl);x=n?a.position[0]:(w-b.outerWidth(!0))/2;h=D()}function D(){return{x:w>b.outerWidth(!0),y:y>b.outerHeight(!0)}}c.isFunction(A)&&(E=A,A=null);var a=c.extend({},c.fn.bPopup.defaults,A);a.scrollBar||c("html").css("overflow","hidden");var b=this,f=c(document),k=c(window),y=k.height(),w=k.width(),N=/OS 6(_\d)+/i.test(navigator.userAgent),v=0,e,h,q,n,g,z,x,t,u,J,H;b.close=function(){r()};b.reposition=function(a){I(a)};return b.each(function(){c(this).data("bPopup")||(l(a.onOpen),v=(k.data("bPopup")||0)+1,e="__b-popup"+v+"__",q="auto"!==a.position[1],n="auto"!==a.position[0],g="fixed"===a.positionStyle,t=b.outerHeight(!0),u=b.outerWidth(!0),a.loadUrl?L():B())})};c.fn.bPopup.defaults={amsl:50,appending:!0,appendTo:"body",autoClose:!1,closeClass:"b-close",content:"ajax",contentContainer:!1,easing:"swing",escClose:!0,follow:[!0,!0],followEasing:"swing",followSpeed:500,iframeAttr:'scrolling="no" frameborder="0"',loadCallback:!1,loadData:!1,loadUrl:!1,modal:!0,modalClose:!0,modalColor:"#000",onClose:!1,onOpen:!1,opacity:.7,position:["auto","auto"],positionStyle:"absolute",scrollBar:!0,speed:250,transition:"fadeIn",transitionClose:!1,zIndex:9997}})(jQuery);

Cant figuure out the control flow of my Javascript program

I'm trying to make a simple Javascript/Jquery program which will cycle through a product carousel I have on the front page of a website.
Here is the code:
jQuery(document).ready( function() {
function next() {
if(window.location.href === window.location.origin + '/') {
var nextButton = jQuery('.prevSlide');
nextButton.trigger('click');
console.log('next');
return;
}
}
function prev() {
if(window.location.href === window.location.origin + '/') {
jQuery('.nextSlide').click();
console.log('prev');
return;
}
}
jQuery('.iosSlider').hover( function() {
jQuery(this).addClass('pauseInterval');
}, function () {
jQuery(this).removeClass('pauseInterval');
}
);
function cycleNext() {
if( !(jQuery('.prevSlide').hasClass('disabled'))) {
if( !(jQuery('.iosSlider').hasClass('pauseInterval'))) {
next();
}
} else {
clearInterval(interval);
intervalTwo = setInterval(cyclePrev, 2000);
console.log('interval cleared');
console.log('intervalTwo set');
return;
}
}
function cyclePrev() {
if( !(jQuery('.nextSlide').hasClass('disabled'))) {
if(!(jQuery('.iosSlider').hasClass('pauseInterval'))) {
prev();
}
} else {
clearInterval(intervalTwo);
var interval = setInterval(cycleNext, 2000);
console.log('intervalTwo cleared');
console.log('interval set');
return;
}
}
var interval = setInterval(cycleNext, 2000);
console.log('interval set');
});
In each of the next() and prev() functions, I check whether I am on the home page, and only proceed if so.
There is also some code there to pause the cycle if the mouse is hovering over the product slider.
When the slider is at the very start or end, a class called 'disabled' is added to the prevSldie and nextSlide anchors.
So ideally I want to click through to the end of the slider, and then click back to the start, then the end, etc.
So the control flow, as I understand it, is as follows:
An interval is set so that the next button on my carousel is clicked every two seconds.
The slider reaches the end, that interval ends and a new one is set.
The previous button is clicked every two seconds until the start of the carousel.
This process repeats infinitely.
Things run fine when the slider runs to the end, the start, and the end again, and then things go haywire.
Console output (should click next and prev 5 times each)
(5) next
interval cleared
intervalTwo set
(5) prev
intervalTwo Cleared
interval set
(5) next
interval cleared
intervalTwo set
interval cleared
intervalTwo set
prev
next
(2) prev
next
(2) prev
next
And it only gets more haywire all over the place from there.
I cant figure out why everything works fine for the first few loops and stops working after that, any help would be hugely appreciated.

Are your intervals scoped correctly? You never define intervalTwo, so it becomes a global. Then also in the cyclePrev function, you use var interval again, which will be scoped to this function and hence won't contain the interval outside the function, that you want to clear once cycleNext gets reached again. Try changing:
var interval = setInterval(cycleNext, 2000),
intervalTwo = null;
console.log('interval set');
And then change var interval = setInterval(cycleNext, 2000); inside cyclePrev into interval = setInterval(cycleNext, 2000);

How to pause and resume jquery interval

I have made a custom slider with jQuery. For this I have used setInterval function:
timer = setInterval(function() {}, 8000);
But I cannot pause and resume the interval. I have 2 buttons (play, pause) which I want to use for. Lets say I click pause after 3 sec, and then resume it. So it should stay in that slider for 5 more seconds and then go to the next one and continue 8 seconds each. I have seen this kinda slider with mouseover pause, but can't do it by myself. I have tried this:
clearInterval(timer);
But this seems reset the interval, don't pause. Can anyone help :)

I'm not entirely sure that's something native to jQuery, however, you could use a flag to pause it, and check in your setInterval whether to execute.
Edit:
Found something that might be useful to you, the jquery-timer
Alternitively, you can keep track of the id set by setInterval, and clear out out when you'd like to pause. Then you can set it again when you wish to resume:
var id = window.setInterval(<code>); //create
window.clearInterval(id); //pause
id = window.setInterval(<code>); //resume

there are two ways of accomplish this:
Clearing the interval everytime you pause and starting a new interval when you resume it.
Having a flag to tell the function in the interval when it is paused and it should not do anything.
The first solution would work like this:
let intervalId = false;
const intervalLength = 8000; // 8 seconds
function intervalFunction () {
// do stuff.
}
startButton.onclick = function () {
if (intervalId === false) {
intervalId = setInterval(intervalFunction, intervalLength);
}
}
pauseButton.onclick = function () {
if (intervalId !== false) {
clearInterval(intervalId);
intervalId = false;
}
}
// auto start it:
intervalId = setInterval(intervalFunction, intervalLength);
The second solution would work like this:
var isRunning = true;
var interval = setInterval(function() {
if (!isRunning) {
// not running, do nothing
} else {
// it is running, do stuff.
}
}, 8000);
pauseButton.onclick = function () {
isRunning = false;
};
startButton.onclick = function () {
isRunning = true;
};

I am not complete sure, that what you are asking for, is the right thing you are showing us... setInterval basically is pure native javascript and in my opinion not worth using! If you wan't to set your timeouts via jquery try this link: http://jchavannes.com/jquery-timer. You can find usages there...
Now on to your problem... you need a state to check wether the slider has to slide or not... simply set a bool like this...
var timer;
var doSlide = false;
var i = 0;
function Slide(){
timer = setTimeout(function(){
if(doSlide == true){
Slide();
i++; // Same as i = i + 1
console.log('Sliding');
if(i == 3) AbortSlide(); /* Abort on third slide! Dont use this in your logic!*/
} else if(doSlide == false){
console.log('Sliding aborted untill next RunSlide() call!')
clearTimeout(timer);
}
},1000);
}
function AbortSlide(){
doSlide = false;
i = 0; // Resetting the count! Dont use this in your logic!
}
function RunSlide(){
doSlide = true;
Slide();
}
RunSlide();
You could also empty the interval in the abort method:
function AbortSlide(){
doSlide = false;
clearTimeout(timer);
i = 0; // Resetting the count! Dont use this in your logic!
}
Here is a working fiddle i made for you to understand what timers and intervals are for: https://jsfiddle.net/q5qzmv68/7/
Hope this helps! Cheers!

window.clearInterval is not working?

I'm using JS to animate two images by having them toggle on and off. I have an initial image which, when the animation is turned on, appears on the screen and stays on. The second image, which has a higher z value, is then set to toggle on and off every 1 second in the same location as the first image, so it appears as if the two are alternating.
I'm using window.setInterval to make the second image blink, but when I need to turn the animation off (and I'm removing both images from the screen), my window.clearInterval is not "working" The first image will be gone, but the second one keeps blinking on and off every second.
Code:
function notebookNotification(setting)
{
$("#lightNotificationContainer").show();
var notificationAnimation = window.setInterval('$("#darkNotificationContainer").toggle()', 1000);
if(setting == 0)
{
window.clearInterval(notificationAnimation);
$("#lightNotificationContainer").hide();
$("#darkNotificationContainer").hide();
}
}
Anyone see why it isn't working?

Reading between the lines, I think what you're saying is this:
You execute notebookNotification(1); and the animation starts
You execute notebookNotification(0); and the animation does not stop.
My guess is that you want notebookNotification(0) to disable the flashing.
In order to do that, you need to rework this function considerably. You need to store the intervalID that comes from setInterval in a variable that survives outside of the scope of this function and can be used for clearInterval on subsequent calls to this function.
For example:
var intervalID;
function notebookNotification(setting)
{
if(setting == 0)
{
if(intervalID) {
window.clearInterval(intervalID);
intervalID = null;
}
$("#lightNotificationContainer").hide();
$("#darkNotificationContainer").hide();
}
else
{
$("#lightNotificationContainer").show();
if(!intervalID) {
intervalID = window.setInterval('$("#darkNotificationContainer").toggle()', 1000);
}
}
}

Here, try this:
http://jsfiddle.net/WGxmy/
Saving the interval to a global variable -- not one inside a function -- lets you clear it later.

var keepflashing = true;
var isShowing = true;
function notebookNotification()
{
if(!isShowing)
$("#lightNotificationContainer").show();
else
$("#lightNotificationContainer").show();
isShowing = !isShowing;
if(keepflashing)
setTimeout( function(){ notebookNotification(setting); },100);
else
{
$("#lightNotificationContainer").hide();
$("#darkNotificationContainer").hide();
}
}

Maybe you can avoid calling clearInterval() generally?
function notebookNotification(setting)
{
if(setting == 0)
{
$("#lightNotificationContainer").hide();
$("#darkNotificationContainer").hide();
}
else
{
$("#lightNotificationContainer").show();
window.setInterval('$("#darkNotificationContainer").toggle()', 1000);
}
}

How to auto refresh HTML only if there has been no activity on a page?

I have a website which I would like to auto refresh ONLY if user is not using it for a specific time (ie.180 sec).Is there a way to auto refresh HTML only if there has been no activity on a page?
Thank you!

Two approaches:
1. Use a once-a-second timer and a "timeout" value.
You probably want to wrap this up in an object:
var activityHandler = (function() {
var timerHandle = 0,
timeout;
flagActivity();
function start() {
stop();
flagActivity();
timerHandle = setInterval(tick, 1000);
}
function stop() {
if (timerHandle != 0) {
clearInterval(timerHandle);
timerHandle = 0;
}
}
function flagActivity() {
timeout = new Date() + 180000;
}
function tick() {
if (new Date() > timeout) {
stop();
location.reload();
}
}
return {
start: start,
stop: stop,
flagActivity: flagActivity
};
})();
Then start it on page load:
activityHandler.start();
And ping it every time you see "activity":
activityHandler.flagActivity();
So for instance, you might do this:
if (document.addEventListener) {
document.addEventListener('mousemove', activityHandler.flagActivity, false);
}
else if (document.attachEvent) {
document.attachEvent('onmousemove', activityHandler.flagActivity);
}
else {
document.onmousemove = activityHandler.flagActivity;
}
2. Use a timer you reset every time there's "activity".
This is less ongoing work (we don't have something happening every second), but more work when you flag that activity has happened.
Set up a timer to do the refresh:
var handle = setTimeout(function() {
location.reload();
}, 180000);
...and then cancel and reschedule any time you see whatever you consider to be "activity":
clearTimeout(handle);
handle = setTimeout(...);
You can wrap this up in a function:
var inactivityTimerReset = (function() {
var handle = 0;
function reset() {
if (handle != 0) {
clearTimeout(handle);
}
handle = setTimeout(tick, 180000);
}
function tick() {
location.reload();
}
return reset;
})();
// Kick start
inactivityTimerReset();
// ...and anywhere you see what you consider to be activity, call it
// again
inactivityTimerReset();
Then, again, ping it on every activity. But this is a lot more work than I'd put in a mousemove handler, hence solution #1 above.

var docTimeOut;
function bodyTimeOut()
{
docTimeOut=setTimeout(function(){location.reload();},18000);
}
function resetTimeOut()
{
clearTimeout(docTimeOut);
bodyTimeOut();
}
document.onload = bodyTimeOut;
document.body.onmouseover= resetTimeOut;

you could declare a variable pageActive or something, set it to false, and whenever user does something set it to true.
Then, set a function to execute periodically as frequently as you want with setinterval() that checks this variable, if it's true set it to false to start again, if is false then refresh page.

You can use onblur and onfocus on body element to see if there is a kind of activity on your page.
