Refreshing Owl Carousel 2

I have 3 divs that activate slide toggle when I click on them. And inside every div there is owl carousel slider.
If I trigger one div the slider shows, but when I click other div slider doesn't show unless I resize the window.
How can I trigger refresh on slide toggle for the slider in every div?
I tried with this on slide toggle but it doesn't work:
$('.owl-slider').trigger('refresh.owl.carousel');

You trigger with a class. You can try with a variable:
var $owl = $('.owl-carousel').owlCarousel({
items: 1,
loop:true
});
$owl.trigger('refresh.owl.carousel');

if .trigger('refresh.owl.carousel'); didn't work with you, you can use
window.dispatchEvent(new Event('resize'));
which will make the carousel refresh automatically.

I want to set new html content for my carousel and the above answers did not worked for me
so I solved my problem with another way
first, define a function to start owlCarousel and run that function
let myCarousel; //a variable thats hold owlCarousel object
function myCarouselStart() {
myCarousel = $('#my-carousel.owl-carousel').owlCarousel(setting);
}
$(document).ready(() => {
myCarouselStart(); // run owl carousel for first time
});
then when you want to refresh the carousel use the below code
myCarousel.trigger("destroy.owl.carousel");
$("#my-carousel").html(newHtmlContent);
myCarouselStart();

Webcam into Slick Slider

I'm working with Slick Slider to generate a dynamic form using templates and one of them contains a webcam plugin.
Everything works but for example, if the slide 4 contains the webcam template, the page asks me if I want to disable or enable my webcam at the very beginning on the slide 0.
So, here is a way to load the webcam plugin WHEN I'm on the slide 4 (or 5...) for example ?
I tried to use JQuery method .hasClass but it's not working:
if ($('div.slick-slide').hasClass('slick-active') == true) {
enableWebcam();}

Try using the slick.js onBeforeChange event to react when the relevant slide is active:
$('.your-slides-class').on('beforeChange', function(event, slick, currentSlide, nextSlide){
if (nextSlide == 3) {
enableWebcam();
}
});
Notice that the slides index starts at 0, so "nextSlide ==3" refers to the fourth slide.
Also, off course you should replace the ".your-slides-class" with... the class or id with which you initiate your slider

So to fix it, here is what I've done :
When the template with the webcam plugin (webcam.js) is generated, I added a class called webcamPlugin to the slide.
I added a function afterChange to check if the ID of the current slide, so div.slick-active div.row, has the same ID as the slide with the webcamPlugin.
If yes, I enable the webcam plugin.

Randomize slides in reveal.js

I have a reveal.js presentation with approximately 300 slides. The purpose of this presentation is to cycle slides in "kiosk mode" on a monitor behind a conference booth.
To create a "kiosk mode" I've got:
Reveal.initialize({
controls: false, // hide the control arrows
progress: false, // hide the progress bar
history: false, // don't add each slide to browser history
loop: true, // loop back to the beginning after last slide
transition: fade, // fade between slides
autoSlide: 5000, // advance automatically after 5000 ms
});
This works very well, but I'd like to randomize the slides. The slides are currently just a list of 300 <section> tags in the index document - they aren't being pulled from anywhere external. Currently random: true isn't a configuration option in reveal.js.
The display order of fragments can be controlled with data-fragment-index. Is it possible to do something like that with sections? Is there a way to trick reveal.js into randomizing my slides?
My preference would be to shuffle them each time around - that is, to show slides 1-300 in random order, and then shuffle them, and show 1-300 again in a different random order. I would also be happy with just jumping to a random slide for each transition, though.

While Reveal itself does not have this functionality built in, it does let you set up event hooks to do actions when all the slides are loaded, this means JQUERY TO THE RESCUE!
You can combine Reveal's "All slides are ready" event with simple javascript to reorder all the sections, here's a simple PoC:
First import jQuery, I did this by adding it directly above the import for js/reveal.min.js:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
Then, set up an event listener:
Reveal.addEventListener('ready', function(event) {
// Declare a function to randomize a jQuery list of elements
// see http://stackoverflow.com/a/11766418/472021 for details
$.fn.randomize = function(selector){
(selector ? this.find(selector) : this).parent().each(function(){
$(this).children(selector).sort(function(){
return Math.random() - 0.5;
}).detach().appendTo(this);
});
return this;
};
// call our new method on all sections inside of the main slides element.
$(".slides > section").randomize();
});
I put this right after declaring my Reveal settings and dependencies, but I'm pretty sure you can put it anywhere.
What this does is waits for all javascript, css, etc to load, manually reorders the slides in the DOM, then lets Reveal start off doing its thing. You should be able to combine this with all your other reveal settings since it's not doing anything disruptive to reveal itself.
Regarding the "shuffling them each time around" portion, the easiest way to do this would be to use another event listener, slidechanged. You could use this listener to check if the last slide has just been transitioned to, after which the next time slidechanged is called you could simply refresh the page.
You can do this with something like:
var wasLastPageHit = false;
Reveal.addEventListener('slidechanged', function(event) {
if (wasLastPageHit) {
window.location.reload();
}
if($(event.currentSlide).is(":last-child")) {
// The newly opened slide is the last one, set up a marker
// so the next time this method is called we can refresh.
wasLastPageHit = true;
}
});

As of reveal.js 3.3.0 there is now a built in helper function for randomizing slide order.
If you want the slide order to be random from the start use the shuffle config option:
Reveal.initialize({ shuffle: true });
If you want to manually tell reveal.js when to shuffle there's an API method:
Reveal.shuffle();
To shuffle the presentation after each finished loop you'll need to monitor slide changes to detect when we circle back to the first slide.
Reveal.addEventListener( 'slidechanged', function( event ) {
if( Reveal.isFirstSlide() ) {
// Randomize the order again
Reveal.shuffle();
// Navigate to the first slide according to the new order
Reveal.slide( 0, 0 );
}
} );

Why is bxslider duplicating my divs

My designer put a bxslider to scroll through 3 divs nicely on my page.
When the page runs, in the html I see it generates 6 divs on the page. It shows div 3, div2, div1, div3, div2, div1.
Just because the duplicated fields on my page now mess up my programing.
Is that neccesary, and is there any way I can touch the code that it shouldn't duplicate my divs?
The page is full of complex code , with an ajax passing the data-serialize to a post form.
Becuase it's all duplicated, now all fields are coming through as 'value,value'. Therefore it's not giving me accurate respones, and well as undefined when it's supposed to be numeric.
My form posts looks like this:
function submitCart () {
$.post(
"scripts/savecart.asp",
$("#form1").serialize()
);}
How could I add that not bx- to it?

As commented in the source code of bxSlider:
if infinite loop, prepare additional slides
So I was able to fix this by adding infiniteLoop: false to the config object:
$(".js-slider").bxSlider({
infiniteLoop: false
});

BxSlider duplicates elements to allow infinite scrolling, etc. For example, say you only have two elements in your slider. Element one might be sliding out on the left, but also sliding in on the right. Therefore, duplicates are required.
If this is a problem, you can usually interact with the duplicates using their bx-clone classes. If you could clarify the actual problem, we could probably give more specific advice.
Update: To eliminate cloned elements from your set, try something like:
$('.bxslider li:not(.bx-clone)')....

I had such problem with bx-clone
I want to use it for an image gallery. So I had a thumbnail image slider and for slider I used bx-slider and on each click on small image , that image in bigger size must show in a div , But on bx-clone clicked nothing happened
I solved that problem with this :
var slider = $('.bxslider').bxSlider({
minSlides: 4,
maxSlides: 4,
slideWidth: 92,
moveSlides: 1,
pager: false,
slideMargin: 10,
onSliderLoad: function(){
$('li.bx-clone').click(function() {
/** your code for bx clone click event **/
});
}
});

Adding to #antongorodezkiy's answer, there is a way to have infiniteLoop: false and still get a non-stopping slide changing: using the onSlideAfter event of the last slide you can, after a few seconds, go back to the first slide and re-start the auto mode:
var pauseTime = 4000; //Time each slide is shown in ms. This is the default value.
var timeoutId;
var slider = $('.bxslider').bxSlider({
auto: true,
infiniteLoop: false,
pause: pauseTime,
onSlideAfter: function ($slideElement, oldIndex, newIndex) {
if (newIndex === slider.getSlideCount() - 1) { //Check if last slide
setTimeout(
function () {
slider.goToSlide(0);
slider.startAuto(); //You need to restart the "auto" mode
},
pauseTime //Use the same amount of time the slider is using
);
}
else { //In case the user changes the slide before the timeout fires
clearTimeout(timeoutId);
slider.startAuto(); //Doesn't affects the slider if it's already on "auto" mode
}
}
});
The difference between this solution and the infiniteLoop: true option is that instead of smoothly transitioning back to the first slide as if it was the next, the slider quickly "rewinds" until reaching the first slide.

for above query: Is it possible to keep having the infinite loop, but remove the clones?
try using below code: if more than 1 item infiniteloop: true else :false
infiniteLoop: ($j("...selector...").length < 2) ? false : true,

Just to answer here, so if some one is struggling and cannot fix the duplication issue. I was facing the same problem that all of my HTML from my page was duplicating inside the first slide under the image tag like bellow:
<img src="public/admin/scr3.png" ><div>..... all of my page HTML...</div></img>
I just found that I was writing the image tag not properly
Meaning my code was something like this for image tag
<img src="public/admin/scr3.png" >
I just replaced my image tag with valid HTML like bellow:
<img src="public/admin/scr3.png" />
and it fixed the content duplication issue.
Hope it will help someone.
Cheers!

I´m not sure if it´s the same issue I was facing, but here´s my case:
My code was using bx slider together with fancybox. And it was duplicating my slides. The solution was to put the secodary code (fancy box), which was generated in my image loop, inside the tag. That did it for me.

bxslider wont stop

I am having an issue where the slider will not stop auto play when I click a link on my navigation menu. I start the slider via:
$('.bxslider1').bxSlider({auto: true,autoControls: true});
It auto plays and works, but if I try to stop the slider by creating an onclick function or .click() jQuery like:
$(".nav-portfolio").click(function() {
slider = $('.bxslider1').bxSlider();
slider.stopAuto();
});
It seems to do something for a split second and then start again. The reason I need to stop the slider is, I am using jQuery waypoints for anchor links to scroll smooth horizontally, and the panels start moving back and fourth by 1 or 2 pixels and its really annoying for the user.
Any help would be appreciated.

Try modifying your code to be:
$(".nav-portfolio").click(function() {
$('.bxslider1').stopAuto();
});
You were previously using the example from the bxSlider webpage which assumes you haven't already initialized the bxSlider. Since you previously initialized it perhaps the second initialization isn't handled gracefully.

Try adding var keyword before the slider declaration.
$(".nav-portfolio").click(function() {
var slider = $('.bxslider1').bxSlider();
slider.stopAuto();
});
