Slick Slider - Multiple Sliders with variations in Slider Length

Hello my dear community,
I'm working on a site with multiple sliders on one site. I use slick.js
Problem ist that the slidesToShow is depending on the number of slider items.
Maximum slidesToShow should be 6
if the number of slides is smaller then 6:
-> slidesToShow should be the number of slider items
I tried this:
$('.carousel').slick({
dots: false,
infinite: true,
speed: 300,
slidesToShow: $(this).querySelectorAll( '.item:not(.slick-cloned)' ).length > 4 ? 6 : 2,
slidesToScroll: 1,
});
Got console error that querySelectorAll is not a function. Also $(this) is the document not the slider in that context.
Also I tried to iterate through the sliders and tried to initializing them one by one but it also does not work
var imgcarousels = document.getElementsByClassName('vaunet-carousel ');
Array.prototype.forEach.call(imgcarousels, function(carousel, index) {
console.log(carousel);
carousel.slick({
dots: false,
infinite: true,
speed: 300,
slidesToShow: 4,
slidesToScroll: 1,
responsive: [
{
breakpoint: 991,
settings: {
dots: true,
arrows: false,
slidesToShow: 1
}
}
]
});
});
Error: carousel.slick is not a function
Any Idea how to make the slidesToShow depending on the slides?
Thanks a ton <3
Regards
Timo

How to make horizontal timeline slider right oriented

In horizontal timeline slider jquery, I want that by default it is right oriented. Like in picture now 2015 prices is on right. I want that most right which is 2017 prices is selected by default and user can scroll to left
My code
$('.timeLine-slider').slick({
dots: true,
infinite: false,
speed: 300,
slidesToShow: 4,
slidesToScroll: 4,
});

Use the initialSlide option.
$(document).ready(function() {
$('.timeLine-slider').slick({
dots: true,
infinite: false,
speed: 300,
slidesToShow: 4,
slidesToScroll: 4,
initialSlide: 4
});
});

<script src="//cdn.jsdelivr.net/jquery.slick/1.6.0/slick.min.js"></script>
<link href="//cdn.jsdelivr.net/jquery.slick/1.6.0/slick.css" rel="stylesheet" />
<div class="timeLine-slider">
<div>2010</div>
<div>2011</div>
<div>2012</div>

How to set the delay before changing slide?

I use Slick slider. I need to set the delay before changing slide, how can I realize this task?
Here is slider's JS-code:
$(".intro__slider").slick({
infinite: true,
dots: true,
dotsClass: "intro__dots",
arrows: false,
swipe: false,
draggable: false
});
var introTitle = $(".intro__title"),
introSlide = $(".intro__slide");
$(".intro__slider").on("beforeChange", function () {
introTitle.addClass("intro__title_hidden");
introSlide.addClass("intro__slide_overlayed");
});
$(".intro__slider").on("afterChange", function () {
introTitle.removeClass("intro__title_hidden");
introSlide.removeClass("intro__slide_overlayed");
});
Here is full code on codepen

try this:
// On before slide change
$('.your-element').on('beforeChange', function(event, slick, currentSlide, nextSlide){
setTimeout(function() {
//your code to be executed after 1 second
}, 1000);
});

You can use autoplaySpeed: 3000, in slick options
$(".intro__slider").slick({
autoplaySpeed: 3000,
infinite: true,
dots: true,
dotsClass: "intro__dots",
arrows: false,
swipe: false,
draggable: false
});

you can use speed to 3000
$(".intro__slider").slick({
infinite: true,
autoplay: true,
autoplaySpeed: 6000,
dots: true,
dotsClass: "intro__dots",
arrows: false,
speed:3000
});
will make the transition in 3 sec, but it won't make a delay, to use a delay I would recommend to use your own dots buttons and the methods slickGoTo , slickNext

Detecting screen size with jQuery and change property

I am using a Slick slider/carousal and displaying six items currently. Now what I want to do is I want the script to detect if the browser has been resized or viewed from a smaller screen (say below 768px) then the number of items displayed should change to 3. This is a perfect replica of the media query function in CSS which detects the screen size for making the website responsive. Just the same thing I want to be performed in my jQuery function but I have never done so. Here is my script:
<script src="https://code.jquery.com/jquery-2.2.0.min.js" type="text/javascript"></script>
<script src="http://kenwheeler.github.io/slick/slick/slick.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript">
jQuery.noConflict();
jQuery(document).on('ready', function() {
jQuery(".center").slick({
dots: true,
infinite: true,
centerMode: true,
slidesToShow: 6,
slidesToScroll: 6
});
});
</script>

The plugin has already way to update the options on different view ports. Please have a look at this. Hope this will help you.
$('.responsive').slick({
dots: true,
infinite: false,
speed: 300,
slidesToShow: 4,
slidesToScroll: 4,
responsive: [
{
breakpoint: 1024,
settings: {
slidesToShow: 3,
slidesToScroll: 3,
infinite: true,
dots: true
}
},
{
breakpoint: 600,
settings: {
slidesToShow: 2,
slidesToScroll: 2
}
},
{
breakpoint: 480,
settings: {
slidesToShow: 1,
slidesToScroll: 1
}
}
// You can unslick at a given breakpoint now by adding:
// settings: "unslick"
// instead of a settings object
]
});

jQuery Slick Slider: How to make a logo ticker slider

I'm currently using the Slick Slider plugin and don't really want to add another plugin to achieve a Logo Ticker slide effect like seen here bxSlider. Any idea how to do it with Slick or if it's even possible?

Set autoplaySpeed to 0 and cssEase to 'linear' to achieve that effect.
$(function() {
$('.your-class').slick({
slidesToShow: 3,
slidesToScroll: 1,
autoplay: true,
autoplaySpeed: 0,
speed: 1000,
cssEase:'linear'
});
});
Example here: https://jsfiddle.net/ugtdjrjt/

There is an autoplay option at Slick Slider
$('.slider').slick({
slidesToShow: 3,
slidesToScroll: 1,
autoplay: true,
autoplaySpeed: 2000,
});
Is that maybe already everything you want?
