In loop mode, duplicate slides are not being updated when the contents of the original slides change #2629
Comments
brandonce commented May 17, 2018
This is a (multiple allowed):
Swiper Version: 4.2.6
Platform/Target and Browser Versions: All browsers, but tested on macOS, CHROME
Live Link or JSFiddle/Codepen or website with issue: https://jsfiddle.net/knankv59/2/
What you did
Swiper config is at the bottom of the Javascript window in the jsfiddle (loop mode, loopedSlides set to 3, slidesPerView set to 1)
Click the right navigation arrow twice to swipe forward to slide 2. Click the button above the slideshow to change the content of slide 2, which now reads «New content!» Click the right navigation arrow six more times, going to the end of the slides and looping back around to slide 2.
Expected Behavior
Slide 2’s text should still say «New content!»
Actual Behavior
Slide 2’s text is still just the original «2».
_ Is there any way to refresh specific duplicate slides automatically when their original slide’s content changes?
The text was updated successfully, but these errors were encountered:
jhowsick commented Jun 12, 2018
Same issue here. Swiper does not update duplicate slides when the original has changed. Any workarounds would be highly appreciated.
brandonce commented Jun 13, 2018
@jhowsick One way is manually redoing the loop by calling methods on the swiper instance itself.
This is hacky though. Hopefully an official fix will happen.

It is not supported and won’t be, it should be done manually, for example like @brandonce described
golee commented Aug 21, 2018
How about something similar with renderExternal() . Sync React or Vue with loop mode is so painful.

I currently use the method that just update html of dupslides

Our swiper, here to note the onTransitionStart function of passing our function to trade the duplicates.
Your slides with events we set:
We handle the duplicates on transition start with this function handleDuplicates()
victorcamargos commented Mar 28, 2019
I was struggling with this behavior as well and since I could not find any solution out of the box for my problem I ended up with a mix of hacks that worked perfectly to me. In my case some slides have a counter and also some buttons, both were not working on duplicated slides. So I used the solution proposed by @golee to copy the dom at the moment of slide transition start (slideChangeTransitionStart) and then on (slideChangeTransitionEnd) I slide it to the realIndex but with speed 0 so it’s not noticed by the user.
peter-wang-wsl commented Apr 18, 2019
@nolimits4web I follow @brandonce described, then found if I have 2 slides in swiper, I only can change the first slide value and can’t change the second one. swiper.loopDestroy() will rollback the value of second slide.
thowfeeq178 commented Apr 25, 2019
//this will update the duplicates only once if you slides update
Hello, I’m having the same problem and can’t fix it. Is possible for you to give me a real example, probably i’m pasting your code in a wrong place.
andykulakov commented Sep 3, 2019
@JoseCigarro you should run these methods whenever the original slides change. this.swiper points at your Swiper instance. Here is an example of how you can access it through Swiper events or swiper’s HTMLElement — http://idangero.us/swiper/api/#initialize

This one is super and awesome fix. You saved my day. Thank you very much.

I use Swiper in Vue with a loop and need change slides data. Of course, the loop doesn’t change duplicates data so I need to use this.loopDestroy () and this.loopCreate () but . when to run them? I came to the point that I have to run them after creating DOM Swiper but how to detect this? Because I use Vue I can fire it on «update», but without it, I don’t have any good idea. Of course, I can use interval and check something in DOM but it sucks in my opinion.
bevndas commented Apr 8, 2020
hmm this fix worked for me before adding a slider destroy the loop swiper.loopDestroy(); Add the slider setTimeout for a sec and update the swiper and create the loop again setTimeout( < directiveRef.update or swiper.update() swiper.loopCreate();>, 1000);
the loop doesnt work properly on slide update so manually updating it! hope it works for you as well!

Initialize Swiper
Now, when we have Swiper’s HTML, we need to initialize it using the following function:
new Swiper(swiperContainer, parameters) — initialize swiper with options
swiperContainer — HTMLElement or string (with CSS Selector) of swiper container HTML element. Required.
parameters — object — object with Swiper parameters. Optional.
Method returns initialized Swiper instance
After you initialize Swiper it is possible to access to Swiper’s instance on its HTMLElement. It is swiper property of Swiper’s HTML container element:
Parameters
Let’s look on list of all available parameters:
Name
Type
Default
Description
allowSlideNext
boolean
true
Set to false to disable swiping to next slide direction (to right or bottom)
Set to false to disable swiping to previous slide direction (to left or top)
If false , then the only way to switch the slide is use of external API functions like slidePrev or slideNext
Set to true and slider wrapper will adapt its height to the height of the currently active slide
Allows to set different parameter for different responsive breakpoints (screen sizes). Not all parameters can be changed in breakpoints, only those which are not required different layout and logic, like slidesPerView , slidesPerGroup , spaceBetween , grid.rows . Such parameters like loop and effect won’t work
Base for breakpoints (beta). Can be window or container . If set to window (by default) then breakpoint keys mean window width. If set to container then breakpoint keys treated as swiper container width
Currently in beta and not supported by Swiper Angular, React, Svelte and Vue components
When enabled it center slides if the amount of slides less than slidesPerView . Not intended to be used loop mode and grid.rows
If true , then active slide will be centered, not always on the left side.
If true , then active slide will be centered without adding gaps at the beginning and end of slider. Required centeredSlides: true . Not intended to be used with loop or pagination
The beginning of the modifier CSS class that can be added to swiper container depending on different parameters
When enabled Swiper will automatically wrap slides with swiper-wrapper element, and will create required elements for navigation, pagination and scrollbar they are enabled (with their respective params object or with boolean true ))
When enabled it will use modern CSS Scroll Snap API. It doesn’t support all of Swiper’s features, but potentially should bring a much better performance in simple configurations.
This is what is not supported when it is enabled:
Cube and Cards effects
speed parameter may not have no effect
All transition start/end related events (use slideChange instead)
slidesPerGroup has limited support
simulateTouch doesn’t have effect and «dragging» with mouse doesn’t work
resistance doesn’t have any effect
allowSlidePrev/Next
swipeHandler
freeMode and all relevant features
direction
‘horizontal’ | ‘vertical’
‘horizontal’
Can be ‘horizontal’ or ‘vertical’ (for vertical slider).
Enable to release Swiper events for swipe-back work in app. If set to ‘prevent’ then it will prevent system swipe-back navigation instead
Area (in px) from left edge of the screen to release touch events for swipe-back in app
CSS selector for focusable elements. Swiping will be disabled on such elements if they are «focused»
If disabled, then slider will be animated only when you release it, it will not move while you hold your finger on it
This option may a little improve desktop usability. If true , user will see the «grab» cursor when hover on Swiper
Swiper height (in px). Parameter allows to force Swiper height. Useful only if you initialize Swiper when it is hidden and in SSR and Test environments for correct Swiper initialization
Setting this parameter will make Swiper not responsive
Whether Swiper should be initialised automatically when you create an instance. If disabled, then you need to init it manually by calling swiper.init()
Index number of initial slide.
Set to false if you want to disable long swipes
Minimal duration (in ms) to trigger swipe to next/previous slide during long swipes
Ratio to trigger swipe to next/previous slide during long swipes
Set to true to enable continuous loop mode
Because of nature of how the loop mode works, it will add duplicated slides. Such duplicated slides will have additional classes:
swiper-slide-duplicate-active — represents slide duplicated to the currently active slide
swiper-slide-duplicate-next — represents slide duplicated to the slide next to active
swiper-slide-duplicate-prev — represents slide duplicated to the slide previous to active
If you use it along with slidesPerView: ‘auto’ then you need to specify loopedSlides parameter with amount of slides to loop (duplicate)
Addition number of slides that will be cloned after creating of loop
Enable and loop mode will fill groups with insufficient number of slides with blank slides. Good to be used with slidesPerGroup parameter
When enabled it prevents Swiper slide prev/next transitions when transitions is already in progress (has effect when loop enabled)
If you use slidesPerView:’auto’ with loop mode you should tell to Swiper how many slides it should loop (duplicate) using this parameter
Array with Swiper modules
Set to true on Swiper for correct touch events interception. Use only on swipers that use same direction as the parent one
Enable/disable swiping on elements matched to class specified in noSwipingClass
Specify noSwiping ‘s element css class
Can be used instead of noSwipingClass to specify elements to disable swiping on. For example ‘input’ will disable swiping on all inputs
Normalize slide index.
Set to true if you also need to watch Mutations for Swiper parent elements
Set to true if you also need to watch Mutations for Swiper slide children elements
Set to true to enable Mutation Observer on Swiper and its elements. In this case Swiper will be updated (reinitialized) each time if you change its style (like hide/show) or modify its child elements (like adding/removing slides)
Register event handlers
Passive event listeners will be used by default where possible to improve scrolling performance on mobile devices. But if you need to use e.preventDefault and you have conflict with it, then you should disable this parameter
When enabled Swiper will force to load all images
Set to true to prevent accidental unwanted clicks on links during swiping
Set to true to stop clicks event propagation on links during swiping
When enabled it won’t allow to change slides by swiping or navigation/pagination buttons during transition
Set to false if you want to disable resistant bounds
This option allows you to control resistance ratio
When enabled it will use ResizeObserver (if supported by browser) on swiper container to detect container resize (instead of watching for window resize)
Set to true to round values of slides width and height to prevent blurry texts on usual resolution screens (if you have such)
Fire Transition/SlideChange/Start/End events on swiper initialization. Such events will be fired on initialization in case of your initialSlide is not 0, or you use loop mode
Enabled this option and plugin will set width/height on swiper wrapper equal to total size of all slides. Mostly should be used as compatibility fallback option for browser that don’t support flexbox layout well
Set to false if you want to disable short swipes
If true , Swiper will accept mouse events like touch events (click and drag to change slides)
CSS class name of currently active slide
By changing classes you will also need to change Swiper’s CSS to reflect changed classes
Not supported in Swiper Angular/React/Svelte/Vue components
slideBlankClass
string
‘swiper-slide-invisible-blank’
CSS class name of blank slide append to fill groups in loop mode when loopFillGroupWithBlank is also enabled
By changing classes you will also need to change Swiper’s CSS to reflect changed classes
Not supported in Swiper Angular/React/Svelte/Vue
CSS class name of slide
By changing classes you will also need to change Swiper’s CSS to reflect changed classes
Not supported in Swiper Angular/React/Svelte/Vue components
slideDuplicateActiveClass
string
‘swiper-slide-duplicate-active’
CSS class name of duplicated slide which represents the currently active slide
By changing classes you will also need to change Swiper’s CSS to reflect changed classes
Not supported in Swiper Angular/React/Svelte/Vue components
CSS class name of slide duplicated by loop mode
By changing classes you will also need to change Swiper’s CSS to reflect changed classes
Not supported in Swiper Angular/React/Svelte/Vue
slideDuplicateNextClass
string
‘swiper-slide-duplicate-next’
CSS class name of duplicated slide which represents the slide next to active slide
By changing classes you will also need to change Swiper’s CSS to reflect changed classes
Not supported in Swiper Angular/React/Svelte/Vue
slideDuplicatePrevClass
string
‘swiper-slide-duplicate-prev’
CSS class name of duplicated slide which represents the slide previous to active slide
By changing classes you will also need to change Swiper’s CSS to reflect changed classes
Not supported in Swiper Angular/React/Svelte/Vue
CSS class name of slide which is right after currently active slide
By changing classes you will also need to change Swiper’s CSS to reflect changed classes
Not supported in Swiper Angular/React/Svelte/Vue
CSS class name of slide which is right before currently active slide
By changing classes you will also need to change Swiper’s CSS to reflect changed classes
Not supported in Swiper Angular/React/Svelte/Vue
Set to true and click on any slide will produce transition to this slide
CSS class name of currently visible slide
By changing classes you will also need to change Swiper’s CSS to reflect changed classes
Not supported in Swiper Angular/React/Svelte/Vue
Add (in px) additional slide offset in the end of the container (after all slides)
Add (in px) additional slide offset in the beginning of the container (before all slides)
Set numbers of slides to define and enable group sliding. Useful to use with slidesPerView > 1
This param intended to be used only with slidesPerView: ‘auto’ and slidesPerGroup: 1 . When enabled, it will skip all slides in view on .slideNext() & .slidePrev() methods calls, on Navigation «buttons» clicks and in autoplay.
The parameter works in the following way: If slidesPerGroupSkip equals 0 (default), no slides are excluded from grouping, and the resulting behaviour is the same as without this change.
If slidesPerGroupSkip is equal or greater than 1 the first X slides are treated as single groups, whereas all following slides are grouped by the slidesPerGroup value.
Number of slides per view (slides visible at the same time on slider’s container).
If you use it with «auto» value and along with loop: true then you need to specify loopedSlides parameter with amount of slides to loop (duplicate)
slidesPerView: ‘auto’ is currently not compatible with multirow mode, when grid.rows > 1
Distance between slides in px.
If you use «margin» css property to the elements which go into Swiper in which you pass «spaceBetween» into, navigation might not work property.
Duration of transition between slides (in ms)
String with CSS selector or HTML element of the container with pagination that will work as only available handler for swiping
Threshold value in px. If «touch distance» will be lower than this value then swiper will not move
Allowable angle (in degrees) to trigger touch move
Target element to listen touch events on. Can be ‘container’ (to listen for touch events on swiper) or ‘wrapper’ (to listen for touch events on swiper-wrapper)
If enabled, then propagation of «touchmove» will be stopped
Enable to release touch events on slider edge position (beginning, end) to allow for further page scrolling
Force to always prevent default for touchstart ( pointerdown ) event
If disabled, touchstart ( pointerdown ) event won’t be prevented
If enabled (by default) and navigation elements’ parameters passed as a string (like «.pagination» ) then Swiper will look for such elements through child elements first. Applies for pagination, prev/next buttons and scrollbar elements
When enabled Swiper will be reinitialized after all inner images ( tags) are loaded. Required preloadImages: true
Swiper will recalculate slides position on window resize (orientationchange)
Required for active slide detection when rendered on server-side and enabled history
userAgent string. Required for browser/device detection when rendered on server-side
Enabled this option and swiper will be operated as usual except it will not move, real translate values on wrapper will not be set. Useful when you may need to create custom slide transition
When enabled Swiper will be disabled and hide navigation buttons on case there are not enough slides for sliding.
Enable this feature to calculate each slides progress and visibility (slides in viewport will have additional visible class)
Swiper width (in px). Parameter allows to force Swiper width. Useful only if you initialize Swiper when it is hidden and in SSR and Test environments for correct Swiper initialization
Setting this parameter will make Swiper not responsive
CSS class name of slides’ wrapper
By changing classes you will also need to change Swiper’s CSS to reflect changed classes
Not supported in Swiper Angular/React/Svelte/Vue
Add event listener that will be fired on all events

Manipulation
Manipulation module adds useful Swiper methods to manipulate slides. It makes sense to use it only with Swiper Core version, not intended to be uses with Swiper Angular, React, Svelte or Vue.
Manipulation Methods
Add new slides to the required index. slides could be HTMLElement or HTML string with new slide or array with such slides, for example:
Add new slides to the end. slides could be HTMLElement or HTML string with new slide or array with such slides, for example:
Add new slides to the beginning. slides could be HTMLElement or HTML string with new slide or array with such slides, for example:
Remove all slides
Remove selected slides. slideIndex could be a number with slide index to remove or array with indexes.
Parallax
Swiper supports parallax transition effects for swiper/slides nested elements. There are two types of parallax elements supported:
Direct child elements of swiper . Parallax effect for such elements will depend on total slider progress. Useful for parallax backgrounds
Slides child elements. Parallax effect for such elements will depend on slide progress
To enable parallax effects you need to init Swiper with passed parallax:true parameter and add one of the following (or mix) attributes to required elements:
data-swiper-parallax — enable transform-translate parallax transition. This attribute may accept:
number — value in px (as for title, subtitle in example above) to move element depending on progress. In this case such element will be moved on ± this value in px depending on slide position (next or previous)
percentage — (as for «parallax-bg») to move element depending on progress and on its size. In this case such element will be moved on ± this percentage of its size (width in horizontal direction, and height in vertical direction) depending on slide position (next or previous). So if element has 400px width and you specified data-swiper-parallax=»50%» then it will be moved on ± 200px
data-swiper-parallax-x — same but for x-axis direction
data-swiper-parallax-y — same but for y-axis direction
data-swiper-parallax-scale — scale ratio of the parallax element when it is in «inactive» (not on active slide) state
data-swiper-parallax-opacity — opacity of the parallax element when it is in «inactive» (not on active slide) state
data-swiper-parallax-duration — custom transition duration for parallax elements

Lazy Loading
To enable lazy loading, first of all we need a special layout for images or elements with background in slides:
Each lazy loaded image/element should have additional «swiper-lazy» class
Lazy image source for element should be specified in «data-src» attribute instead of «src»
Lazy image source set for element should be specified in «data-srcset» attribute instead of «srcset»
Lazy background image source should be specified in «data-background» attribute
You may also add animated preloader spinner to slide which will be removed automatically after image loaded:
Or white one for dark layout:
After that we need to enable lazy loading on Swiper initialization:

Using Build Script
Swiper comes with gulp builder that allows to build custom library version where you may include only required modules. We need the following:
Download and unzip Swiper GitHub repository to local folder
Install Node.js (if not installed)
Now, we need to install required dependencies. Go to the folder with downloaded and unzipped Swiper repository and execute in terminal:
Open scripts/build-config.js file:
Now, we are ready to build custom version of Swiper:
That is all. Generated CSS and JS files and their minified versions will be available in dist/ folder.
TypeScript Definitions
Swiper is fully typed, it exports Swiper and SwiperOptions types:
You can also check auto generated TypeScript definitions explorer for all the types, options, properties and methods.
