Slick Carousel Blank

I set up an overlay slick carousel, so when you click on the image a larger carousel appears with the selected image as the initialSlide. However, Slick carousel is adding several blank slides after the initialSlide. The blanks only appear when you click next starting with the third slide. When you click on the previous button the blank slides do not appear. What am I doing wrong?
$("#sync1 .item").on("click", function() {
var index = $(this).attr("data-slick-index");
$(".overlay-carousel-container").css("display", "block");
$("body").css("overflow", "hidden");
$("#overlayCarousel").slick({
slidesToShow: 1,
slidesToScroll: 1,
fade: true,
initialSlide: index,
focusOnSelect: true
});
})
$(".close").on("click", function() {
$(".overlay-carousel-container").css("display","none");
$("body").css("overflow", "inherit");
$("#overlayCarousel").slick("unslick");
$("#executiveOverlay").slick("unslick");
});

The Jquery attr() function returns a string value. When you pass that into the slick constructor function it translates it to a different number.
Adding a simple Number() function to change the index to numeric should solve your problem. Just place the following middle line between the lines I placed it:
var index = $(this).attr("data-slick-index");
index = Number(index);
$(".overlay-carousel-container").css("display", "block");

This answer is for the people who are struggling slick carousal as I also faced a lot of problem with it, even though it seems very easy as mentioned but I found out that it has lots limitation.
Very old
To have exact same look like mentioned it needs CSS(SCSS) which is difficult to do in development which as a new user I realised it quite late. Or you don't get dots and arrows with the same exact look easily.
Several other issues like the one mentioned here and other I found over stack flow.
The best one I resorted to for similar process is the one mentioned here
it's latest
and comes with a simple tutorial as well

iDangero Swiper using Worklight?

Is there an easy way to implement this? I am having trouble getting it to work properly. I tried following the instructions on the website to have it load at window.onload, but Worklight seems to fire that call before the DOM is even visible, so I couldn't do that. I have some initialization code and so I am calling the following method in that code:
function runSwiper(){
// iDangerous Swiper
var mySwiper = new Swiper('.swiper-container', {
pagination : '.pagination',
loop : true,
grabCursor : true,
simulateTouch : true,
paginationClickable : true
});
}
Yet, all I see in my carousel is just Text. I have two test slides in there currently, but the slide doesn't even seem to work on my Android emulator. Is there anything else I need to be doing for this to work properly? If not, is there something that works as nicely as this that will play nice with Worklight?
I am using worklight version 6.2. I am usingth is: http://www.idangero.us/sliders/swiper/api.php
What I am aiming to do is fade out one div that has information, and fade in another div that has more info and the Swiper present, so initially this swiper will be hidden.

I turns out, in my case, the easiest way to call the swiper to initialize was later on (being that it was in a hidden div) instead of at window.onload. In addition, I had some issues with slides disappearing, which I fixed by having the slides pre-defined in the HTML instead of adding them dynamically.

Getting Uncaught TypeError: undefined is not a function in nivo slider.js

Help me to sought out this error..thanks!!

Include jquery.js main file in header before any js
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
When you use two different versions of jquery (which is not recommended), you can use
jQuery.noConflict
api.jquery.com/jQuery.noConflict/

I had encountered a similar problem before. This issue can be fixed by making use of Jquery Update module in Drupal 7 & setting the version of jquery library to 1.9 & above.
Do let me know in case of any doubts

Also please note that in Drupal you should never add Jquery library explicitly because Drupal core by default adds a jquery library.
When you try to add a jquery.js in the head
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
There will be 2 jquery libraries now & which will conflict.
So we need to use jquery update module to upgrade the library

Another likely candidate is referring to jQuery with $ (dollar):
$(document).ready(function(){
// Target your .container, .wrapper, .post, etc.
$("#main-content").fitVids();
});
If you instead use the no-conflict reference in your script, as below, this may fix the error
jQuery(document).ready(function(){
// Target your .container, .wrapper, .post, etc.
jQuery("#main-content").fitVids();
});

I just ran into some issues configuring Nivo View Slider on Drupal 7.
I didn't read the module's documentation at first but it looks like Nivo Slider's library isn't included in the package, you need to upload it manually to your server.
Here is the documentation : https://www.drupal.org/project/views_nivo_slider
To sum it up :
install/enable Library API
download Nivo Slider libs from https://github.com/gilbitron/Nivo-Slider/downloads
unzip the archive to sites/all/libraries/nivo-slider
At step 2, you'll have to choose between version 2.x or 3.x
On the module's project page, it says that version 3.x might be broken on Google Chrome, I didn't have any issue myself...

fraction slider not working

I've downloaded Fraction Slider from #jacksbox and have gone through the documentation countless times now and cannot figure out why my slider won't show the effects it's supposed to. This is the site I'm working on: http://pacificdesignacademy.com/NEW/2 and this is an example of what the slider is supposed to do: http://jacksbox.de/stuff/jquery-fractionslider/.
Here is the path to my js: ../NEW/2/fractionslider/jquery.fractionslider.js
And here is the path to my css ../NEW/2/fractionslider/fractionslider.css
All of the images are just stacking on top of one another regardless of me defining overflow:hidden on the containing element.
Not sure what else to do here, so any help is greatly appreciated. I'm supposed to launch this site September 1st... eep!
Thanks!

A simple check in the browser's console showed you have a syntax error on line 594 of your page. You have a closing parenthesis instead of an opening brace.
UPDATE After you fixed that, you're now getting the error :
Uncaught ReferenceError: jQuery is not defined
I suggest you move your code and place it after you've included both jQuery and the slider plugin, so your page should look like this:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script type="text/javascript" src="fractionslider/jquery.fractionslider.js"></script>
<script type="text/javascript">
jQuery(window).load(function(){
$('.slider').fractionSlider({
'fullWidth': true,
'controls': true,
'pager': true,
'responsive': true,
'dimensions': "1200,400",
'increase': false,
'pauseOnHover': true
});
});
</script>

You are missing an opening parenthesis when calling the plugin.
Change
$('.slider').fractionSlider()
To
$('.slider').fractionSlider({
On line 593

FractionSlider is garbish! Use LiquidSlider instead!
What one doesn't have but exist in the other:
well formated object oriented code,
automatic hardware acceleration with the new CSS3 transforms if the browser supports it (no js animation here!),
keyboard navigation,
hash linking where user can bookmark a specific slide or land to a page that opens slider to a specific slide,
many effects,
mobile 'swap' support
user extensible.
Of course it uses some other libraries and code snipets 'stolen' from here and there (https://hacks.mozilla.org/2011/09/detecting-and-generating-css-animations-in-javascript/ but actually it's reduntant as the use of Moderniz library in responsive designs makes the detection as simple as a one-line command, http://easings.net/ for the easing equations, https://daneden.me/animate/ for the transformations etc.)
The idea behind FractionSlider is indeed unique but the implementation sucks!

Javascript making text slide in from html

I am trying to make a text-slide-in effect on a web page. I am using the javascript slidesjs library because it seemed like the best fit. However, I cannot make it work when triggered by a web click.
I have a live example running at: http://107.22.173.10
Note that when you click the "GOTO" links nothing happens.
The basic code is as follows and it seems the page is supposed to automatically put '#' anchors in to trigger the slides. I can't make this work, or figure out how to debug this.
$(function(){
// Set starting slide to 1
var startSlide = 1;
// Get slide number if it exists
if (window.location.hash) {
startSlide = window.location.hash.replace('#','');
}
// Initialize Slides
$('#slides').slides({
preload: true,
preloadImage: 'img/loading.gif',
generatePagination: true,
//play: 5000,
//pause: 2500,
hoverPause: true,
// Get the starting slide
start: startSlide,
animationComplete: function(current){
// Set the slide number as a hash
window.location.hash = '#' + current;
}
});
});
Does anyone see what's going wrong here?
What is the best way to debug this problem?
Is there a better way or library I should be using?
Any advice is appreciated. Thanks!!

You're not following the example from slidesjs.com. See "Basic HTML structure". You're putting only one element in the #slides_container div, and assign all sorts of weird absolute positioning to it, which of course won't work with the animation code.
Copy paste the example first, then start adding your own tweaks concerning style.
