I'm using slidesjs to create a slideshow on my site, this is working fine but I want to add a incremented class to the body tag e.g. slide-1 at load and then when the slide changes slide-2 etc until the slide fully rotates and it goes back to slide-1
My current code is;
<script>
$(function(){
$('#feature-slideshow').slides({
preload: true,
preloadImage: '<?php bloginfo('template_url'); ?>/images/loading.gif',
generateNextPrev: false,
effect: 'fade',
play: 5000,
hoverPause: true,
animationStart: function() {
$("body").addClass("slide");
}
});
});
</script>
I have two problems;
1) the I want the initial class set before the slideshow has loaded so that the style which is a background is applied when the page is loaded rather than the slideshow
2) How to increment the slide-x class when the slideshow is transitioned/changed.
Any help would be greatly appreciated
Just add the initial class to body directly (<body class="slide-1">). No need to let JavaScript do this since it will always start at slide 1.
To increment that number you can set the currentClass option so that we can get the index of the current slide with .index().
$(function(){
var slideshow = $("#feature-slideshow");
slideshow.slides({
preload: true,
preloadImage: '<?php bloginfo('template_url'); ?>/images/loading.gif',
generateNextPrev: false,
effect: 'fade',
play: 5000,
hoverPause: true,
currentClass: "current"
animationStart: function() {
var idx = slideshow.children(".current").index();
document.body.className = "slide-"+(idx+1);
}
});
});
Ok managed to get this to work, thanks to Marcus for his help, I just tweaked your code to pickup the correct list 'pagination' which had the current class applied;
$(function(){
var slideshow = $("#feature-slideshow");
slideshow.slides({
preload: true,
preloadImage: '<?php bloginfo('template_url'); ?>/images/loading.gif',
generateNextPrev: false,
effect: 'fade',
play: 5000,
hoverPause: false,
currentClass: "current",
animationStart: function() {
var idx = $('ul.pagination').children(".current").index();
document.body.className = "slidebg-"+(idx+1);
}
});
});
I had to apply slidebg-3 to the body tag as for some reason when the slideshow cycles it includes the first list
Works great though apart from removing all other body classes, I suppose I could add it as an ID as I'm not using one of those
Anyway hope this helps someone else!

I am using uikit modal on a project. I am also using JS Textillate to animate the text when the modal is opened. However, I want the text to be animated if the modal is closed and opened again continuously. For now, it only animate once when the modal is opened for the first time, when closed and opened again, the animation does not run again.
This is the JavaScript code below:
$(".uk-modal-full").on('show', function(){
var $title = $(".txt").textillate({
// in animation settings.
in: {
effect: "fadeIn", // set the effect name
},
// out animation settings.
out: {
effect: "fadeOut",
delayScale: 0,
delay: 0,
},
type: "char",
autoStart: true,
});
var $title = $(".txt2").textillate({
// in animation settings.
in: {
effect: "fadeIn", // set the effect name
},
// out animation settings.
out: {
effect: "fadeOut",
delayScale: 0,
delay: 0,
},
type: "char",
autoStart: true,
});
});
I am thinking maybe the function can be removed when modal closes so that it can be repeated when it is opened again. I am not sure if that is possible as I am only a Jquery learner.
$(".uk-modal-full").on('hide', function(){
// code here?
});
Full options for Textillate is here https://github.com/jschr/textillate
UPDATE
Thank you! I have created a codepen here to test my full code inside a modal using your example. It seems to be working but with some issues. When I use $element.textillate('in') and $element.textillate('out'), the other options do not work (e.g. initialDelay). It seems to only control the "in" and "out" options. When I used $element.textillate('start') and $element.textillate('stop'), the other options worked but when modal is reopened, the text are briefly loaded first before animating.
Please see codepen here - https://codepen.io/ajaxthemestudios/pen/XWJRBbW
Looking through the readme of Textillate, I think this section is what you need:
$element.textillate('start') - Manually start/restart textillate
$element.textillate('stop') - Manually pause/stop textillate
$element.textillate('in') - Trigger the current text's in animation
$element.textillate('out') - Trigger the current text's out animation
So I would do something like first define the animations (outside the event functions)
var title1 = $(".txt").textillate({
// in animation settings.
in: {
effect: "fadeIn", // set the effect name
},
// out animation settings.
out: {
effect: "fadeOut",
delayScale: 0,
delay: 0,
},
type: "char",
autoStart: false,
});
var title2 = $(".txt").textillate({
// in animation settings.
in: {
effect: "fadeIn", // set the effect name
},
// out animation settings.
out: {
effect: "fadeOut",
delayScale: 0,
delay: 0,
},
type: "char",
autoStart: false,
});
And then in the event function:
$(".uk-modal-full").on('show', function(){
title1.textillate('in');
title2.textillate('in');
}
EDIT
I got it to work in this codepen: https://codepen.io/thomas-short/pen/zYxdzWY
Test it by clicking on click repeatedly.
EDIT 2
The problem of the text being briefly visible seems to be a limitation of the library. I could not find a way to solve it using the tools they provide. The only way I managed to make it work is by control it myself:
$(".uk-modal-full").on('show', function(){
title1.textillate('start');
$(".txt2").hide();
setTimeout(() => {
$(".txt2").show();
title2.textillate('start');
}, 1500);
})
And remove initialDelay from the options
I'm running the latest version of Bxslider (4.2.14), everything works great except for the pager.
When using the pager to switch between slides, pause is much shorter than it should be:
Steps to reproduce:
Open the Fiddle: https://jsfiddle.net/Bruno42/smvhe3o4/7/
When Slide #2 appears wait ~3-4 seconds
Switch back to Slide #1 by clicking on the pager
Pause should then last 5 seconds (like during the "auto" mode), but instead it lasts only 1-2 seconds
I think the Pause countdown should be resetted to 5 seconds every time a slide is selected using the Pager.
I spent a while trying to figure out a solution in the clickPagerBind() function in jquery.bxslider.js by using clearInterval(slider.interval); to fix this, however it did not work (slider gets stuck after that).
Code used to load bxSlider (also available on my JsFiddle):
$('.bxslider').bxSlider({
maxSlides: 1,
slideWidth: 800,
pager: true,
pagerType: 'full',
autoHover: false,
auto: true,
stopAuto: false,
stopAutoOnClick: false,
speed: 1000,
pause: 5000,
mode: 'horizontal',
controls: false,
});
I would really appreciate your help on that.
The speed: 1000 might be too fast for the transition to complete and for startAuto() and stopAuto() methods to start or end. In order to control what methods are called during transition we can use a callback from the bxSlider API. Make a custom function and call it on either onSlideAfter or onSlideBefore. The following demo calls function pagerFix() onSlideAfter:
function pagerFix($bx, prv, nxt) {
bx.stopAuto(true);
bx.goToSlide(nxt);
bx.stopAuto(false);
bx.startAuto(true);
}
When initializing .bxSlider() make sure you reference it so you can call the methods.
let bx = $('.bxslider').bxSlider(...
Fiddle
(uses onSlideBefore)
Demo
(uses onSlideAfter)
let bx = $('.bxslider').bxSlider({
slideWidth: 800,
auto: true,
speed: 1000,
pause: 5000,
controls: false,
onSlideAfter: pagerFix
});
function pagerFix($bx, prv, nxt) {
bx.stopAuto(true);
bx.goToSlide(nxt);
bx.stopAuto(false);
bx.startAuto(true);
}

like the title i'm using bxslider at my website, actually i'm using vertical thumbnail slide now, but the problem is, it's look ugly when at mobile width, so i want to change it like normal slider with arrow. can you help me how to do that? here is the things i want:
1. at normal using vertical thumb slide
2. when the width triggered at specify width, the thumb is hide (maybe display none at css)
3. Do destroyslider for stopping the vertical thumb slider and change it to normal slider with arrow
4. when the width is normal again, it will switch again to vertical thumb slider
ok here is my jquery:
var mainImage;
$(window).load(function() {
mainImage = $('.product-gallery').bxSlider({
infiniteLoop: false,
hideControlOnEnd: true,
pager: false,
controls: false,
auto: false,
minSlides: 1,
maxSlides: 1,
moveSlides: 1,
mode: 'fade',
adaptiveHeight: true
});
$('.product-gallery-thumbs ul').bxSlider({
infiniteLoop: false,
hideControlOnEnd: true,
pager: false,
auto: false,
minSlides: 4,
maxSlides: 4,
moveSlides: 1,
slideWidth: '100%',
mode: "#{options['product_thumbnail_direction']}",
slideMargin: 10,
onSliderLoad: function(currentIndex) {
$('.product-gallery-thumbs ul li').eq(0).addClass('active')
}
});
$('.product-gallery-thumbs ul li').each(function() {
$(this).click(function() {
$(this).addClass('active').siblings().removeClass('active');
mainImage.goToSlide($(this).index());
});
});
});
when do destroy :
mainImage.destroySlider();
here is normal slider with arrow:
mainImage.bxSlider({
mode: 'fade',
captions: true,
slideWidth: 600
});
UPDATE :
I try to did this, when do destroy is work, but when switching to normal arrow slider it doesn't work. Hope you guys can help me fix this
$(document).ready(function(){
setMaxWidth(767px);
mainImage.destroySlider();
function setMaxWidth(767px) {
mainImage.bxSlider({
mode: 'fade',
captions: true,
slideWidth: 600
});
})
bx.reloadSlider() Method
The method destroySlider() returns bxSlider as it was initially so don't use it if you want to change bxSlider after a reload, instead use reloadSlider(). Besides the obvious (reloading bxSlider), you can load a different set of options. Note: There are 2 Object Literals:
var cfgA = {...} and var cfgB = {...}
Each of them has key/value pairs (or properties) that are from the bxSlider API. When calling .bxSlider(), simply load one of configurations:
var bx = $('.bx').bxSlider(cfgA);
onSliderResize Callback
As far as slider plugins go, bxSlider isn't the most stable and it can get buggy as browsers update and bxSlider stagnates at v.4.2.12, but there's one thing bxSlider excels in is callbacks. I've written complex programs that are controlled by bxSlider callbacks because they are reliable and never break. In this demo onSliderResize call the function reloadBX(currentIndex). **Note: ** the absence of parenthesis on reloadBX():
onSliderResize: reloadBX
reloadBX(currentIndex)
This is the heart of the Demo. For demonstration purposes I've bound the function to a convenient button. When testing the Demo, you should expect the following by either clicking the RELOAD button, or resizing bxSlider:
Toggling between cfgA and cfgB
Relocates to the position index bxSlider was on before the reload.
Shifts images to adjust at reload to avoid images being stuck halfway.

I am using bxslider to create a slideshow of my images. The images are updating dynamically. My problem is the sideshow fade-in and fade-out work even only one image is present. How can I stop this ?
bxslider options are
var coverSlider = $('.bxslider').bxSlider({
auto: true,
minSlides: 1,
maxSlides: 1,
pager: false,
speed: 500,
pause: 3000,
autoHover: true,
mode: 'fade',
controls: false
})
I am using reload method to update the slider when a new image is appends or removes
coverSlider.reloadSlider();
this helps me:
$(document).ready(function(){
$('.bxslider').bxSlider({
mode: 'fade',
auto: ($(".bxslider li").length > 1) ? true: false,
pager: ($(".bxslider li").length > 1) ? true: false,
controls: false
});
});
You should check the number of images before reloading, and use destroySlider() method if there is only 1 image.
// Get the quantity of images (add your code if you want an example)
var numberOfImages = ...;
if (numberOfImages > 1) {
coverSlider.reloadSlider();
} else {
coverSlider.destroySlider();
}
Try
var numImgs = $('div.myClassName img').length;
if(numImgs>1)
{
\\Do your bxslider reload here
}
Instead you can use Jquery Selector too like below
jQuery(".image").Length
Hope this helps...
Click here to read about selectors Click
var numImgs = $('div.bxslider img').length;
if (numImgs > 1) {
$('.bxslider ').bxSlider({
controls: true,
...
});
}
This solution works for me
Change auto: true
to
auto: ($('#slidername').children().length < 2) ? false : true

bx slider : how to disable slide show when only one image is present?
Set auto to false:
var coverSlider = $('.bxslider').bxSlider({
auto:false
})
I am using the jQuery plugin for Nivo Slider and need to find a way to stop it from transitioning when only one image exists.
Can you set the option:
manualAdvance: true
Will that help? This is the documentation for the latest NivoSlider update.
If this wont help, can you post the code you are using to enable the slider?
This will be the full code:
$(window).load(function() {
$('#slider').nivoSlider({
slices: 1, // For slice animations
startSlide: 0, // Set starting Slide (0 index)
manualAdvance: true, // Force manual transitions
captionOpacity: 0.8, // Universal caption opacity
randomStart: false, // Start on a random slide
beforeChange: function(){}, // Triggers before a slide transition
afterChange: function(){}, // Triggers after a slide transition
slideshowEnd: function(){}, // Triggers after all slides have been shown
lastSlide: function(){}, // Triggers when last slide is shown
afterLoad: function(){} // Triggers when slider has loaded
});
});
There is probably a better way to do it but it works for me:
if($('#slider img').length == 1) {
$('#slider').nivoSlider({});
$('.nivo-controlNav').css('display', 'none');
$('.nivo-directionNav').css('display', 'none');
$('#slider').data('nivo:vars').stop = true;
} else {
$('#slider').nivoSlider({
effect: 'slideInLeft'
});
}
PS. It's important to check the number of images before initializing Nivoslider because it seems to duplicate image tags...
None of the answers quite worked for me, because I still wanted a single image to display with a caption. I ended up using slightly different options to initialise the nivoSlider depending on the number of images (my images were in a containing div with the id 'hero-images'):
var numImages = $('#hero-images img').length;
if (numImages === 0) {
//No images - hide the block
$('#hero-images').hide();
} else if (numImages === 1) {
// 1 image - disable controls and set to manual advance to prevent animation
$('#hero-images').nivoSlider({
directionNav: false,
manualAdvance: true,
controlNav: false
});
} else {
// Multiple images, set up as normal
$('#hero-images').nivoSlider({
effect: 'fade',
directionNav: false
});
}
