Why does my cycle slideshow hide all the slides? - jquery-plugins

The jQuery plugin cycle looks for elements of class slideshow. I want to add this class to a <ul> element to make a slideshow out of its <li>s. But when I add the slideshow class to the <ul> element, all <li> disappear and I get no slideshow whatsoever.
The HTML looks like this:
<ul>
<li>
<h3 class="expander">...</h3>
<div class="content">
<p>...</p>
<h4>...</h4>
<ul class="slideshow">
<li>...</li>
<li>...</li>
</ul>
</div>
</li>
...
</ul>
As you see, the slideshow <ul> is included in another list. This parent list consists of headers which reveal the content of each list item on click. I am hiding all the .contents programmatically when the DOM is ready. Then, I add a click listener to the .expanders so they can show the hidden .contents.
It is inside these .contentss that I have .slideshows which use the cycle plugin to cycle through their list items.
The other weird thing about all this is that the slideshow's worked perfectly before I transformed my headers into toggles for their associated content. Indeed, when I added the toggle functionality to the headers, the slides are no longer visible. But then if I take away the slideshow class, they are visible again. Of course, they no longer have slideshow functionnality...
Here is the javascript for all this:
$(document).ready(function()
{
var expanders = $('.expander');
expanders.each(function()
{
$('.content', $(this).parent()).toggle();
$(this).click(function()
{
$('.content', $(this).parent()).toggle("blind", {"easing":"easeInOutCirc"}, "normal");
});
});
$('.slideshow').each(function() {
var parent = $(this).parent();
$(this).cycle(
{
fx: 'scrollHorz',
easing: 'easeInOutCirc',
timeout: 0,
nowrap: 1
});
});
});
Any idea what could be causing this problem?

Apparently, I needed to move the cycle code above the toggle code, like this:
$(document).ready(function()
{
$('.slideshow').each(function() {
var parent = $(this).parent();
$(this).cycle(
{
fx: 'scrollHorz',
easing: 'easeInOutCirc',
timeout: 0,
nowrap: 1
});
});
var expanders = $('.expander');
expanders.each(function()
{
$('.content', $(this).parent()).toggle();
$(this).click(function()
{
$('.content', $(this).parent()).toggle("blind", {"easing":"easeInOutCirc"}, "normal");
});
});
});
I don't know why this works though, so better answers would be appreciated.

Prototype.js: Showing the next hidden div

How do I show a hidden adjacent div on Prototype.js? Here is my current code:
<button id="checkAnswer" onclick="checkAnswer2()">Check Answer</button>
<p class="feedback">Feedback:</p>
Script:
function checkAnswer2 () {
$('checkAnswer').next().show();
}
If you put the ID in the function, you’re going to have to make a new function for each question/answer pair. How about this:
<button class=“checkAnswer”>Check Answer</button>
<p class=“feedback”>Feedback:</p>
script
$$('.feedback').invoke('hide');
$(document).on('click', '.checkAnswer', function(evt, elm){
elm.next('p').show();
});
Now you can repeat as many of these as you want on the page, and each button will always manage whatever p follows it.

using foundation 5 joyride with tabs

Is there a way to switch tabs with foundation 5 Joyride?
I have foundation tabs on the page and want Joyride to point elements on different tabs.
Like mentioned in the comment from Steven, you could use the callback either in the pre or post step callback function you activate the tab you need.
post_step_callback : function (){}, // A method to call after each step
pre_step_callback : function (){} // A method to call before each step
Hope this helps...
Here's what worked for me. I looked around and couldn't find anything useful, so wrote this. The hardest part was figuring out how to get the id of the target anchor. This was found buried in the 'this' object available to the callback.
$(this.$target)[0].id;
The 'content' class is used by foundation to identify the content to display when a tab is clicked. So traversing up the .parents tree finding the enclosing elements gives you the content tab(s) holding your link. And then of course you have to add an id to the <a> element of the tab you want to click. If you name it the same as your content div, with '-a' appended, you should be good to go.
html:
<dl class="tabs radius" data-tab id="my_tabs">
<dd class="active">Tab 1</dd>
<dd class="active">Tab 2</dd>
</dl>
<div class="tabs-content">
<div class="content" id="tab1">
<article id="joyride_stop1">...</article>
</div>
<div class="content" id="tab2">
<article id="joyride_stop2">...</article>
</div>
</div>
js:
$(document).ready(function() {
$(document).foundation('joyride', 'start', {
pre_step_callback: function(i, tip) {
var target = $(this.$target)[0].id;
if($('#' + target).parents('.content').length > 0) {
$('#' + target).parents('.content').each(function() {
var id = $(this).attr('id');
if($('#' + id).is(':visible') == false) {
$('#' + id + '-a').click();
}
});
}
}
});
});
This will work on any page, whether it contains tabs or not, so it can be universally included across a site.

Highlight Current Menu Item Using Prototype JS

The challenge is to set current menu item as active in magento, which uses Prototype JS and not JQuery.
<ul id="mainmenu">
<li>home</li>
<li><a id="menuItem" href="{{store url='our-cakes'}}">Our Cakes</a></li>
<li>About us</li>
<li>Outlets</li>
<li>Franchise</li>
<li>contact us</li>
</ul>
<script type="text/javascript">// <![CDATA[
document.observe("dom:loaded", function() {
$(mainmenu).childElements().each(function(e){
var h = e.down('a').readAttribute('href');
if(h == window.location){
e.addClassName("current");
}
});
});
// ]]></script>
Here's a refinement of that method. Note that depending on the browser, the href of a link and the window.location.href may have a substring match, but not a full match, because of the rest of the URL which the browser provides from context. Just == is not going to make it.
var here = $$('#mainmenu a').sortBy(function(a){
return a.href.length;
}).reverse().find(function(a){
return window.location.href.include(a.href);
});
if(here) here.up().addClassName('current');
Also, this is looking for the longest match first, so you don't get all of the menu items highlighted on the home link /.

Infinite Scroll on ajax loaded content

I'm doing a WP_Query on let's say page-a.php, that page has a div called target where page-b.php is being loaded into. Page-a is a custom template and page-b is an archive page.
The structure on page A as example:
<body>
<div id="wrap">
<div class="target">
while
<div class="post">
<h1>Title</h1>
<p>Description</p>
</div>
endwhile
<div class="pagination"></div>
</div>
</div>
</body>
On page-b I only include the < post > and < pagination > divs within a regular wp loop.
Now the jQuery:
$(window).load(function() {
$('.target').infinitescroll({
navSelector : ".navigation",
// selector for the paged navigation (it will be hidden)
nextSelector : ".navigation a.next",
// selector for the NEXT link (to page 2)
itemSelector : ".post",
// selector for all items you'll retrieve
debug : true,
loading: {
finishedMsg: '<div class="alert alert-info" style="margin-top:50px"><p class="center">All posts were loaded</p></div>',
img: '',
msg: null,
msgText: "<p style='text-align:center; margin-top:50px;'><i style='font-size:60px; color:#babfc8'class='fa fa-cog fa-spin'></i></p>"
}
}, function(arrayOfNewElems){
$('.post').animate({"opacity":"1","max-height":"150px","padding":"15px 8px"},800, "jswing");
}
);
});
-If I call that script on page-a.php will only work on it, once page-b content is placed on
-If I call on page-a.php and page-b.php it works on first, then when first ajax content is loaded and then (if I apply a new filter) it won't work.
-If I call the script on my ajax response function it will work once, then if I apply another filter and target div refreshes content, I get the
Uncaught TypeError: Cannot call method 'appendTo' of null
div classes called (.target and .post) are present on the page.
What the hell am I doing wrong here. Thanks.
PS: If you need to take a look at the real scripts let me know and I will provide.
I think you need this : http://www.247techblog.com/implement-infinite-scroll-functionality-wordpress-wp-ajax-function/

twitter bootstrap dynamic carousel

I'd like to use bootstrap's carousel to dynamically scroll through content (for example, search results). So, I don't know how many pages of content there will be, and I don't want to fetch a subsequent page unless the user clicks on the next button.
I looked at this question: Carousel with dynamic content, but I don't think the answer applies because it appears to suggest loading all content (images in that case) from a DB server side and returns everything as static content.
My best guess is to intercept the click event on the button press, make the ajax call for the next page of search results, dynamically update the page when the ajax call returns, then generate a slide event for the carousel. But none of this is really discussed or documented on the bootstrap pages. Any ideas welcome.
If you (or anyone else) is still looking for a solution on this, I will share the solution I discovered for loading content via AJAX into the Bootstrap Carousel..
The solution turned out to be a little tricky since there is no way to easily determine the current slide of the carousel. With some data attributes I was able to handle the .slid event (as you suggested) and then load content from another url using jQuery $.load()..
$('#myCarousel').carousel({
interval:false // remove interval for manual sliding
});
// when the carousel slides, load the ajax content
$('#myCarousel').on('slid', function (e) {
// get index of currently active item
var idx = $('#myCarousel .item.active').index();
var url = $('.item.active').data('url');
// ajax load from data-url
$('.item').html("wait...");
$('.item').load(url,function(result){
$('#myCarousel').carousel(idx);
});
});
// load first slide
$('[data-slide-number=0]').load($('[data-slide-number=0]').data('url'),function(result){
$('#myCarousel').carousel(0);
});
Demo on Bootply
I combined #Zim's answer with Bootstrap 4. I hope it will help someone.
First, load just the path of the images:
<div id="carousel" class="carousel slide" data-ride="carousel">
<div class="carousel-inner">
<div class="carousel-item" data-url="/image/1.png"></div>
<div class="carousel-item" data-url="/image/2.png"></div>
<div class="carousel-item" data-url="/image/3.png"></div>
</div>
</div>
Then in JavaScript:
$('document').ready(function () {
const loadCarouselImage = function ($el) {
let url = $el.data('url');
$el.html(function () {
let $img = $('<img />', {
'src': url
});
$img.addClass('d-block w-100');
return $img;
});
);
const init = function () {
let $firstCarousel = $('#carousel .carousel-item:first');
loadCarouselImage($firstCarousel);
$firstCarousel.addClass('active');
$('#productsCarousel').carousel({
interval: 5000
});
};
$('#carousel').on('slid.bs.carousel', function () {
loadCarouselImage($('#carousel .carousel-item.active'));
});
init();
});
