I'm using idangero.us swiper as an image slider and I have the option to enable the pagination and keep track of what image I'm on. The page is loaded via ajax. Here's my script,
$('#a1').bind('pageshow', function(e){
var mySwiper = new Swiper('.swiper-container',{
pagination: '.pagination',
grabCursor: true,
paginationClickable: true })
});
Now when the page is loaded in the DOM, I get the swiper's effects and the pagination is visible, but it doesn't track my images unless I navigate away then go back. Any idea on why this is?
Ah, well now I feel like an idiot. Nothing wrong with how it was calling the swiper, it was bad html. My structure was messed up and was affecting how the swiper would work.

I get some problem when I use owl-carousel in my Rails project.
when I go back to the cached page of my browsers which is using carousel class, I get too many carousel owl-dot classes in my page,this is my
JS code
function initScrollboxHobby() {
var owl = $(".owl-carousel");
owl.owlCarousel({
// loop: true,
items: 1,
nav: true
});
}
and issue HTML code
How to fix it ?
I guess you are using turboinks and when you go back the page is cached by it and when it loads it reruns the owl carousel init function.
The problem, básically, is that turbolinks doesn't play well with non-idempotent functions https://github.com/turbolinks/turbolinks#making-transformations-idempotent
I've managed to make a workaround for this problem with other js plugins, so it should work for you.
Básically, the idea is:
First, when the user enters the page for the first time, copy the content of the element with class .owl-carousel on itself as a data attribute
carousel = $('.owl-carousel');
carousel.data('originalHtml', carousel.html();
carousel.owlCarousel(....)
Then, when the users goes back, before initializing the carousel, check if it was initialized and cached, in that case, first replace the content with the original and remove classes
carousel = $('.owl-carousel');
if (carousel.hasClass('owl-loaded')) {
carousel.html(carousel.data('originalHTML')).removeClass('owl-theme owl-loaded owl-drag');
}
carousel.owlCarousel(....)
You can mix both steps into one:
$(function() {
const carousel = $('.owl-carousel');
if (carousel.hasClass('owl-loaded')) { //if it has the class then it means it's the cached view
carousel.html(carousel.data('originalHTML')).removeClass('owl-theme owl-loaded owl-drag');
} else { // else it's a fresh load of the page
carousel.data('originalHtml', carousel.html());
}
carousel.owlCarousel(....)
})
It's a little bit hacky, but the only way I found to use plugins that are not prepared to work with turbolinks without going through modifying those plugins.
Another option would be to just disable Turbolinks if you thing you just don't need it.
For arieljuod's help of problem reason and my own trying.
I coded like this now.
var owl = $(".owl-carousel");
var owl_navs = $('.owl-carousel .owl-nav');
var owl_dots = $('.owl-carousel .owl-dots');
var owl_cloned = $('.owl-carousel .owl-stage-outer .owl-stage .cloned');
if(owl.hasClass('owl-loaded'))
{
owl_navs.remove();
owl_dots.remove();
owl_cloned.remove();
}
owl.owlCarousel({
loop: true,
items: 1,
nav: true
});
It's tedious but worked well.
Now,I understanded reason.
When I go back to cached page,because I wrote javascript code in my ERB file,in that way, old HTML code may changed.
And then Turbolinks function will run the JS code in that CHANGED new HTML code,Turbolinks must do that,because when I visit cached page again,it will lose all the event binds.
So the whole carousel items will be messy.
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.
I'm having a trouble with a jQuery image slider that works only the first time i open its page !
I have one main page, that includes via Ajax three page portions (Home, Presentation and Contact), the home portion contains the image slider !
To move through the pages, i use another jQuery page slider which includes the right portion and plays a sliding animation to show it !
So when i go for example from the home page to the presentation page, and then comeback to home ... the image slider isn't working anymore, and sometimes doesn't even appear !
What does it mean ?
How can i make sure the script is reloaded after the page slider finishes the transition, cause i think the problem comes from it ?
$(document).ready(function() {
$('#slides').slidesjs({
width: 700,
height: 300,
play: {
active: false,
auto: true,
interval: 3000,
swap: true
}
});
$(".menuButton").click(function() {
var page = $(this).attr("id");
var cont = $("#container");
var cont1 = $("#container1");
cont1.load("parts/"+page+".html", function() {
cont.hide("slide", {direction:"right"}, function() {
cont1.show("slide", {direction:"left"});
});
});
});
});
Thank you.
If the script is included in the portions loaded by ajax, it won't run (ajax loaded scripts are not ran by default). So basically, after the success event, just call the functions from the script.
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.
I use jqtouch and iscroll for my app.
I load all pages with ajax and when I go back from a ajax loaded page to the index (menulist) page, that page scrolls to the top.
How can I prevent this?
Thanks.
have you tried to set the option checkDOMChanges to false?
I believe there is a boolean option called topOnDOMChanges
var scroll = new iScroll(contentid, {
desktopCompatibility: true,
bounce: true,
momentum: true,
checkDOMChanges: false,
topOnDOMChanges: false
});
