Remember last viewed slide on refresh with slick.js

I'm using slick.js as a content browser. As such, my slider has a number of images to peruse through. I'd like to be able to refresh the web page and have slick remember the last slide I was viewing. I'm new to jquery and javascript so any guidance would be appreciated.
Here's the code I'm working with:
$(document).ready(function(){
// Carousel Options
$('.mycarousel').slick({
infinite: true,
accessibility: true, mobileFirst: true,
adaptiveHeight: true,
arrows: false, draggable: true,
useCSS: true, cssEase:'linear', focusOnSelect: true,
dots: true, appendDots:$(document.innerHTML = "<p> </p>"),
lazyLoad: 'ondemand',
});
$('.leftArrow').on('click', function(){
$('.mycarousel').slick("slickPrev");
});
$('.rightArrow').on('click', function(){
$('.mycarousel').slick("slickNext");
});
$(window).on('resize orientationchange', function() {
$('.mycarousel').slick('resize');
});
});

I myself did some research and this is what I found:
$('#yourCarousel').on('slid.bs.carousel', function () {
var currentSlide = $('#yourCarousel div.active').index();
sessionStorage.setItem('lastSlide', currentSlide);
});
if(sessionStorage.lastSlide){
$("#yourCarousel").carousel(sessionStorage.lastSlide*1);
}
Instead of sessionStorage you could also use:
localStorage.setItem('lastSlide', currentSlide)

How to disable animation while animating using mousewheel and slick slider?

I have a slick slider on my website, and i'm using also jquery-mousewheel to switch slides. The issue is that i want to disable the mousewheel while it's sliding.
Do you know how i can do this ?
function detectScroll() {
$('body').bind('mousewheel', function(e){
if(e.originalEvent.wheelDelta /120 > 0) {
$('.slickSlider').slick('slickPrev');
}
else{
$('.slickSlider').slick('slickNext');
}
});
}
$('.slickSlider').slick({
vertical: true,
verticalSwiping: true,
autoplay: false,
slidesToShow: 1,
slidesToScroll: 1,
arrows: false,
dots: false,
infinite: false
})
detectScroll()

I found a solution!
The thing is that I had to declare a boolean that i called animating. Then I used the on('beforeChange') and on('afterChange') of slick to detect rather the animation is finished or not. And I just had to check if the the animating is true or false in the beginning of the mousewheel function and return false if it's true.
I hope it would help a lot of people!
var animating = false;
function detectScroll() {
$('body').bind('mousewheel', function(e){
//If animated than we wait the animation to be over
if (animating) {
return false;
}
if(e.originalEvent.wheelDelta /120 > 0) {
$('.slickSlider').slick('slickPrev');
}
else{
$('.slickSlider').slick('slickNext');
}
});
}
$('.slickSlider').slick({
vertical: true,
verticalSwiping: true,
autoplay: false,
slidesToShow: 1,
slidesToScroll: 1,
arrows: false,
dots: false,
infinite: false
})
$('.slick').on('beforeChange', function(event, slick, currentSlide, nextSlide){
animating = true;
}).on('afterChange', function(event, slick, currentSlide, nextSlide){
animating = false
});
detectScroll()

Slick Carousel - Cannot Read Property 'slickAdd' in INIT call

This is a weird one for me. I have a Slick.js Carousel, and after it initializes, I was to check the window width, and if the width is small enough, ADD a new slide to the beginning of the carousel.
JS:
var posterSlide = "<div class='item mobile-poster'>PUT STUFF IN HERE</div>"
$(document).ready(function(){
$('.featured-carousel').on('init', function(event, slick){
console.log('on init');
if ($(window).width() < 737) {
addPosterSlide();
}
});
$('.featured-carousel').slick({
dots: true,
infinite: true,
speed: 1000,
slidesToShow: 1,
slidesToScroll: 1,
autoplay: true,
autoplaySpeed: 10000,
arrows: true,
focusOnSelect: true
});
});
function addPosterSlide(){
$('.featured-carousel').slick('slickAdd', posterSlide, true);
}
The Slick.js Carousel loads in correctly, and the init call fires, but then I get a Uncaught TypeError Cannot read property 'slickAdd' of undefined INSIDE the function that is seeing is the slider has been initialized.

Cycle once and stop on the first slide

I am trying to make the bxslider cycle through three slides and then return to the first slide and stop the slideshow in that position. I've tried different bits of code but I can't find anything that specifically addresses this kind of action. Any help is appreciated.
$(document).ready(function(){
$('.bxslider').bxSlider({
auto: true,
autoControls: true,
pause: 5000,
slideMargin: 0
});
});

The simplest way I can think of would be to insert a second copy of the first slide at the end so you have three slides and then another copy of the first and you tell it not to auto-repeat.
$(document).ready(function() {
$('.bxslider').bxSlider({
auto: true,
autoControls: true,
pause: 5000,
infiniteLoop: false, // don't auto-repeat
slideMargin: 0
});
});
Beyond that, you could specify a callback and after the third slide finishes displaying, you could stop the auto-advance and then tell it to goto the first slide.
$(document).ready(function() {
var slider = $('.bxslider').bxSlider({
auto: true,
autoControls: true,
pause: 5000,
infiniteLoop: false,
slideMargin: 0,
onSlideNext: function($slideElement, oldIndex, newIndex) {
if (newIndex >= 3) {
slider.stopAuto();
slider.goToSlide(0);
}
}
});
});
If you only have three slides (a fact you haven't included that would have helped us), then perhaps you won't get an onSlideNext event when infiniteLoop is off. In that case, you could use the onSlideAfter method and trigger after showing the third slide.
$(document).ready(function() {
var slider = $('.bxslider').bxSlider({
auto: true,
autoControls: true,
pause: 5000,
infiniteLoop: false,
slideMargin: 0,
onSlideAfter: function($slideElement, oldIndex, newIndex) {
if (newIndex >= 2) {
slider.stopAuto();
setTimeout(function() {
slider.goToSlide(0);
}, 5000); // put whatever time here you want the 3rd slide to show
}
}
});
});

Did you try this using callback?
var slider = $('.bxslider').bxSlider(options); //your default options here.
$('.bxslider').bxSlider({
onSlideAfter: function($slideElement, oldIndex, newIndex){
//if slide number is 3
if(newIndex === 2){
slider.goToSlide(0);
slider.stopAuto();
}
});
What this code will do is, it will callback onSlideAfter function as soon as the slide is changed.. If the slide index is 3 then the code will stop autoplay after going to first slide..
Used callbacks and methods :
onSlideAfter (callback)
goToSlide (method)

bxSlider not working automatically

I want the bxSlider to automatically start the slideshow without the user clicking on it. This is my code (which isn't working):
slider = $('.slider1').bxSlider({
slideWidth: 1012,
slideHeight:200,
minSlides: 1,
slideMargin: 0,
controls: false,
auto: true,
autoStart: true
});
slider.startAuto();
What's wrong with this? What happens is that images do load, but it never autoscrolls, the user always have to choose one of the pager dots to manually scroll through. What's wrong with my code?

You should use
$(document).ready(function(e) { });
or
$(window).ready(function(e) { });
in between the code.
so the correct one should be,
$(document).ready(function(e) {
$('.slider1').bxSlider({
slideWidth: 1012,
slideHeight:200,
minSlides: 1,
slideMargin: 0,
controls: false,
auto: true,
});
});
hope this will help you...!

This Code worked for me!
var slider = $('#slider').bxSlider();
$('.bx-next, .bx-prev, .bx-pager a').click(function(){
// time to wait (in ms)
var wait = 1000;
setTimeout(function(){
slider.startAuto();
}, wait);
});
You can set wait on 0 if you don't want a delay. And because I used: pagerCustom: '#pager', I changed '.bx-pager' a into '#pager a'.

This was all , what was missing and i got it from bxslider official page
$(document).ready(function(){
$('.bxslider').bxSlider({
mode: 'fade',
auto: true,
autoControls: true,
pause: 2000
});
});

Try setting autoControls: true (from http://bxslider.com/examples/auto-show-start-stop-controls)

Okay! I got the same problem! And none of the solution worked above. But I found what was wrong!
1 - First Check and make sure you have auto:true in jQuery script like below:
$('.bxslider').bxSlider({
auto: true,
pause: 3000,
pager: true
});
2 - The main jQuery file that you are using, kindly update that jQuery file, you might be using old jQuery file! (#2 was the issue in case of mine)
Thanks!

This code is also working perfectly
jQuery(function(e){
jQuery('.bxslider').bxSlider({
mode: 'fade',
captions: true,
autoplay:true,
autoControls: true,
auto: true,
autoplaySpeed:1000
});
});

I suggest the following remedy. onSlideAfter is executed after each slide transition. Then this code will cause slider.startAuto() to be executed each time this happens, starting auto show.
var slider = $(".sliderBx ul").bxSlider({
auto: true,
pager: true,
controls: true,
onSlideAfter: function () {
slider.startAuto();
}
});
