Have a slider in website header that uses JavaScript and Jquery to change its tabs every 6 seconds or when the user clicks one of its tabs. I use it in my project in Webflow (a page builder) and the problem I face is that whenever slide changes, currently focused form window loses focus.
I'm no programmer even though I'm learning js now, but if after some investigation I think that the .w--current class is used both for slider and form focus in Webflow's master js file.
Here is my live project:
https://bauserwis-com-pl.webflow.io/
I found some solutions that use IntersectionObserver API to tell if the header is in viewport and stop the setInterval timer, but I struggle with integrating it with my code. Or perhaps is there a different solution? I don't mind slides changing in the background, I only want to stop the form from losing focus.
Thanks in advance.
var tabTimeout;
clearTimeout(tabTimeout);
tabLoop();
// Cycle through all tabs.
function tabLoop() {
tabTimeout = setTimeout(function() {
var $next = $('.tabs-menu').children('.w--current:first').next();
if($next.length) {
$next.click(); // user click resets timeout
} else {
$('.standard-tab:first').click();
}
}, 6000); // 6 second tab loop (change this)
}
// Reset loop if a tab is clicked
$('.standard-tab').click(function() {
clearTimeout(tabTimeout);
tabLoop();
});
});

A long content sub-page has multiple "read more" buttons done with jquery toggleClass.
When a user click the "read more" button the content is showing and the page gets refreshed. (I need the page-refresh for various reasons).
When the page gets refreshed, of course the content is not unfold anymore.
What I am trying todo is:
Save all unfold / fold toggle content before the page-refresh.
Go to the same scroll position before the page-refresh.
I am not sure what is the best way to keep the information -> Cookies, sessionStorage or localStorage for my case, because the user will usually open more sub-pages with "read more" buttons.
I made a JSFiddle (page refresh is not working on a fiddle).
I'd advise using sessionStorage for this.
First, remove all onclick=refreshPage() from your HTML. You want to keep all JS code inside your JS, and to set all handlers at one place. As a best practice, do not use onclick at all.
Next, create two functions: loadState() and saveState(). You will need to call call loadState() on every page load (refresh), and saveState() everytime a toggle button is clicked.
In your handler for clicks on button, also perform the page refresh.
The entire JS code:
$(window).on('load', function() {
loadState();
});
$('.read-more-toggle').on('click', function() {
$(this).next('.read-more-content').toggleClass('hide');
saveState();
refreshPage();
});
// Fold or unfold each content based on state before refresh
// And go to same scroll position before refresh
function loadState() {
let hidden_states = sessionStorage.getItem('hidden-states');
if (!hidden_states) {
return;
}
hidden_states = hidden_states.split(',');
$('.read-more-content').each(function(i, elem) {
if (hidden_states[i] === 'hide') {
elem.classList.add('hide');
}
else {
elem.classList.remove('hide');
}
});
document.scrollingElement.scrollLeft = sessionStorage.getItem('scroll-x');
document.scrollingElement.scrollTop = sessionStorage.getItem('scroll-y');
}
// Remember fold & unfold states, and scroll positions
function saveState() {
let hidden_states = [];
$('.read-more-content').each(function(i, elem) {
hidden_states.push(elem.classList.contains('hide') ? 'hide' : 'show');
});
sessionStorage.setItem('hidden-states', hidden_states);
sessionStorage.setItem('scroll-x', document.scrollingElement.scrollLeft);
sessionStorage.setItem('scroll-y', document.scrollingElement.scrollTop);
}
function refreshPage() {
window.location.reload();
}
Note: If at all possible, try to avoid a page refresh. Storing view states then recreating them after a refresh feels sub-optimal. In some browsers, it may also result in occasional scroll jump glitches as it repaints the restored states.
Lastly, consider if you really need jQuery for your project. Most functionality can be implemented in vanilla JS.
I'm trying to learn some JS / Jquery and trying to implementing some functions toghether to learn in how to do it.
My goal is to make a progress bar, that only fires up if while the tab is ative. This function should be thriggered when document ready or after X seconds.
I've already got some of the achievements but it's hard to complete it.
My actual code:
$(document).ready(function(){
$(window).focus(function(){
var progress = $(".loading-progress").progressTimer({
timeLimit: 15,
onFinish: function () {
alert("ok");
},
showHtmlSpan: false,
});
});
});
<div class="loading-progress"></div>
The main problems:
1 - If I open the page, I need to change the tab and come back to focus and start. The point it's to start right away since the tab is focused.
2 - It doesn't stop if change tab. If I change tab, why the code keeps running since I put into the focus windows code?
3 - I have no clue in how to make it wait X seconds or document ready.
Can someone help me trying to figure it out these 3 aspects? Thanks.
I found this article helpful for what I was needing to do, which was have a slideshow of sorts with a tab and tab_container using JavaScript. The code works great:
Automatic tab switch in javascript or jquery
However, what I want it to do is if you let the page run, it keeps rotating between the tabs. But if a tab is manually clicked on (example, they want to read the content on that tab) it stops the auto-rotation of the tabs for the duration of while they are on that webpage. If the page is refreshed, or they go back to the page, it starts the tab rotation again.
I'm not sure the Javascript code that I can add to the above example to make the auto-rotation stop.
Thanks in advance for the help!
You can use clearInterval to stop the setInterval function from running. setInterval returns an ID and you can pass that ID to clearInterval to stop it, e.g.
var intervalID = setInterval(function() {
....
clearInterval(intervalID);
So just make the code
var intervalID = setInterval(function() {
....
tabs.on('click', 'a', function(e) {
clearInterval(intervalID);
$(this).trigger('slides.swap');
e.preventDefault();
});
I'd also change the setInterval function from triggering a click to just straight-up triggering slides.swap, so that you know the difference between a triggered click and a user's click:
$('a:eq('+idx+')').trigger('slides.swap');
Here's the updated Fiddle from that question.
I have an add-to-bag button used throughout our site and we want a dynamic popup to appear to acknowledge what was just added, and then it goes away. I'm finding that if you click another add button, it has the previous dialog's timeout attached. To fix this so the next dialog has its own 10,000 setTimeout rather than whatever is left over from the last one I have come up with the following code (that doesn't do the trick).
$(document).ready(function ()
{
// Create object for future dialog box - so it's available to the close method
var addToBagDialogVar = $('<div id="addToBagDialogBox"></div>');
var autoCloseTimeout = 10000;
var dialogTimer;
$(".addToBagPU").click(function (e)
{
var result = "";
$.get(this.href, function (data) { SetData(addToBagDialogVar, data); });
return false;
});
// Start listening for the close link click
$(document).on("click", "#bagPUCloseLink", function (event)
{
event.preventDefault();
CloseDialog(addToBagDialogVar);
});
function SetData(addToBagDialogVar, data)
{
result = data;
var regex = data.match("{{(.*)}}");
var bagCount = regex[1];
addToBagDialogVar.html(result).dialog({
open: function ()
{
clearTimeout(dialogTimer);
$(".ui-dialog-titlebar-close").hide();
SetBagCount(bagCount),
dialogTimer = setTimeout(function () { CloseDialog(addToBagDialogVar); }, autoCloseTimeout);
},
show: { effect: "fadeIn", duration: 800 },
close: function () { clearTimeout(dialogTimer); },
width: 320
});
}
function CloseDialog(closeThisDialog)
{
closeThisDialog.dialog("close");
closeThisDialog.dialog("destroy").remove();
}
});
The dialog is loaded with dynamic content from an external .Net page with product data and has a close link inside that page, which is why the dialog is loaded into addToBagDialogVar so it's available to CloseDialog.
All of that works just fine. It's just the reset of the timer that doesn't appear to be happening. If I go down a page of products and add each one to my bag, the 3rd or 4th dialog is only up for a second or so because they have all been using the first dialogs setTimeout.
I've read and read and tried too many different ways to remember and now my brain is mush.
I propose an alternate explanation for the behavior you're observing. When you click the first "add to cart", a timer is started. As you go down the page clicking "add to cart", a new timer is started each time. There's no overlap, just a bunch of separate timers running normally (although incidentally, each new dialog box blows away the timer ID you've previously created; I'll come back to this).
When your first dialog's timer expires, the dialog closes itself via the HTML ID, meaning it closes itself with something like a jquery $('div#addToBagDialogBox').closeOrSomethingLikeThat(), that is, every dialog inside a div with an id of addToBagDialogBox. The first timer expiration is closing all of your dialogs, because they all use that same HTML ID. The other timers are running perfectly, but when they expire there's nothing left for them to do.
You can fix the early-close problem by assigning a unique HTML ID to each dialog you create. And you'll want to manage your timer IDs on a per-dialog basis as well, such that each dialog has its own timer ID.
Edit: Just for nerdy grins, think about the details of the scenario you described. Your first timer is running, counting down normally, and you start four other timers while the first dialog is still there. The ID of the fifth timer is in your variable dialogTimer. So when the first dialog's timer expires, the close processing occurs, and you call clearTimeout with the ID of the fifth dialog's timer. So your first dialog's timer expired, the dialog closed all the other dialogs, and the cleanup cancelled the fifth timer. There are three other timers still running, their IDs lost forever. They finally expire and their shutdown functions run, but they're totally without effect, their companion dialogs long gone. Sorry, bona fide nerd here.
Looking at other questions here they seem to report setInterval is disabled or slowed down when a tab is hidden. I am seeing a different problem - calls to setInterval appear to "stack" and then all get applied when the tab is shown.
In my case I have a slider which animates an image on the site homepage every few seconds. If I go to another tab for a minute or two then return, the slider goes crazy... all the animations fire one after another until it is caught up.
I tried adding code to stop the animation happening if another is already in progress, but it doesn't work... maybe the timer events get queued in some way that circumvents my test.
setInterval(function(){
if (!rotationQueued) {
rotationQueued = true;
rotate_slide('next');
}
}
So, I want the JS to pause when the tab is hidden - or to act as normal - anything but this!!
You could try something like this:
function runRotate() {
return window.setInterval(function(){
if (!rotationQueued) {
rotationQueued = true;
rotate_slide('next');
}
});
}
var run = runRotate();
window.addEventListener('focus', function() {
run = runRotate();
},false);
window.addEventListener('blur', function() {
window.clearInterval(run);
},false);
You would basically look to see if the browser window is focused or not and then run or disable the setInterval function depending on the event returned.
