I'm trying to create previous / next buttons on each accordion body.
I can't figure out a way to collapse / expand a certain section. I tried removing the class in from the accordion-body but that does not seem to collapse.
$(".accordion-body").each(function(){
if($(this).hasClass("in")) {
$(this).removeClass("in");
}
});
Also whenever or whatever I use the .collapse method on, I get a javascript error saying that object has no method collapse.
The in class is just an indicator that a section is open. The Javascript module applies the same inline styles as .in does, so removing the class is insufficient.
You need to use the module's API to programmatically interact with the accordion, via the .collapse() method:
$('.accordion-body').each(function(){
if ($(this).hasClass('in')) {
$(this).collapse('toggle');
}
});
Or, you can condense this down to:
$('.accordion-body.in').collapse('toggle');
If you want only to collapse any open sections:
$('.accordion-body').collapse('hide');
If you want only to expanded any closed sections:
$('.accordion-body').collapse('show');
Here is another solution:
/**
* Make an accordion active
* #param {String} id ID of the accordion
*/
var activateAccordion = function (id) {
// Get the parents
var parents = $('a[href="#' + id + '"]').parents('.panel-group').children('.panel');
// Go through each of the parents
$.each(parents, function (idx, obj) {
// Check if the child exists
var find = $(obj).find('a[href="#' + id + '"]'),
children = $(obj).children('.panel-collapse');
if (find.length > 0) {
// Show the selected child
children.removeClass('collapse');
children.addClass('in');
} else {
// Hide the others
children.removeClass('in');
children.addClass('collapse');
}
});
};
The important part of the code is the combination, remembering the .collapse class, not just using .in:
// Show the selected child
children.removeClass('collapse');
children.addClass('in');
and
// Hide the others
children.removeClass('in');
children.addClass('collapse');
The above example has been tested in Twitter's Bootstrap v3.3.4
This works for accordions in Bootstrap 3:
var selector = $('.panel-heading a[data-toggle="collapse"]');
selector.on('click',function() {
var self = this;
if ($(this).hasClass('collapsed')) {
$.each(selector, function(key, value) {
if (!$(value).hasClass('collapsed') && value != self) {
$(value).trigger('click');
}
});
}
});
I'm simulating a click of the other accordion tabs with $(value).trigger('click');. According to the API you should just be able to use the .collapse() method i.e. $(value).collapse('hide');. But it doesn't work for some reason so trigger it is...
For this kind of problem use addClass("in"); only because of using ".collapse('toggle/Hide/Show');" will disturb the future toggle functionality.
Another related use case is when we have forms inside accordions & we want to expand accordion with validation errors. Extending the answer by Daniel Wright
https://stackoverflow.com/a/12698720/6504104, we can do something like
/**
* Expands accordions that have fields with errors
*
*/
var _expandAccordions = function () {
$form = $('.my-input-form');
// you can adjust the following lines to match your form structure / error classes
var $formGroups = $form.find('.form-group.has-error');
var $accordions = $formGroups.closest('.accordion-body');
$accordions.each(function () {
$(this).collapse('show');
});
};
I did,
$('.mb-0').click(function(){
$('.collapse').collapse('hide');
$('.collapse.in').collapse('show');
});
and this works for me
Using Bootstrap 4 add the following buttons inside the card body
<input type="button" class="btn btn-secondary btn-block btn-sm mt-3 text-center card-proceed-next" value="Proceed" />
<input type="button" class="btn btn-secondary btn-block btn-sm mt-3 text-center card-proceed-prev" value="Previous" />
Add the following javascript (includes Azhar Khattak show panels with validation errors):
$(function () {
$('.card-proceed-next').click(function (e) {
e.preventDefault();
$(e.target).closest('.collapse').collapse('hide'); // hide current accordion panel
$(e.target).closest('.card').next('.card').find('.collapse').addClass('show'); // show next accordion panel
});
$('.card-proceed-prev').click(function (e) {
e.preventDefault();
$(e.target).closest('.collapse').collapse('hide'); // hide current accordion panel
$(e.target).closest('.card').prev('.card').find('.collapse').addClass('show'); // show previous accordion panel
});
var $elErrors = $('#accordion').find('.field-validation-error'); // elements with error class
var $accordionsWithErrors = $elErrors.closest('.collapse'); // accordions with error elements
if ($accordionsWithErrors.length > 0) $('.collapse').collapse(); // collapse all accordion panels due to the first accordion panel shown as default
$accordionsWithErrors.each(function () {
$(this).addClass('show'); // show accordion panels with error messages
});
});

I am using materialize to create an accordion collapsible on my page. I want to add gifs/images to my page when the collapsible header is clicked and want to remove them when that collapsible header is clicked again or another header is clicked.
I am able to add the gifs on click but have not been able to figure out how to remove them. I am using javascript and jquery.
Below is my code:
contentTitles = ["Test1", "Test2", "Test3"];
contentLinks = ["test1.gif", "test2.gif", "test3.gif"];
$(document).ready(function(){
$('.collapsible').collapsible();
$('main').append('<ul data-collapsible="accordion"></ul>');
$('ul').addClass('collapsible popout');
for (var j = 0; j < contentTitles.length; j++) {
$('ul').append('<li></li>');
// start the creation of the collapsible
$('.collapsible').collapsible({
accordion: false, // A setting that changes the collapsible behavior to expandable instead of the default accordion style
});
};
// create the collapsible
$('li').append('<div><i></i></div>');
$('li').append('<div><span></span></div>');
$('i').addClass('material-icons');
$('i').parent().addClass("collapsible-header hoverable");
$('span').parent().addClass("collapsible-body");
// adds the titles to each collapsible header
$('.collapsible-header').each(function(index) {
$(this).html(contentTitles[index]);
})
// adds the gif urls to each collapsible body
$('.collapsible-header').on('click', function() {
$('.collapsible-body').each(function(index) {
$(this).html('<iframe class="gif" src=' + contentLinks[index] + '>');
})
})
$('.collapsible-header').on('click', function() {
$('.collapsible-body').html();
})
})
});
Thank you.
The .html() call just returns the html content of the element - it doesn't change it. If you want to empty the element, do this:
$('.collapsible-header').on('click', function() {
$('.collapsible-body').html(""); //set HTML to be an empty string
})
EDIT: I cleaned up the code a bit and narrowed down the problem.
So I'm working on a Wordpress site, and I'm trying to incorporate drop-downs into my menu on mobile, which means I have to use jQuery to assign classes and id's to my already existing elements. I have this code that already works on premade HTML, but fails on dynamically created id's.
Here is the code:
...
var menuCount = 0;
var contentCount = 0;
//find the mobile menu items
var submenus = $('[title="submenu"]');
if (submenus.length && submenus.parent('.fusion-mobile-nav-item')) {
console.log(submenus);
submenus.addClass('dropdown-title').append('<i id="dropdown-angle" class="fa fa-angle-down" aria-hidden="true"></i>');
submenus.each(function() {
$(this).attr("href", "#m" + menuCount++);
})
var content = submenus.parent().find('ul.sub-menu');
content.addClass('dropdown-content');
content.each(function() {
$(this).attr("id", "m" + contentCount++);
})
}
$(document).on('click', '.dropdown-title', function(e) {
var currentAttrValue = $(this).attr('href');
if ($(e.target).is('.d-active') || $(e.target).parent('.dropdown-title').is('.d-active')) {
$(this).removeClass('d-active');
$(currentAttrValue).slideUp(300).removeClass('d-open');
} else {
$('.dropdown-title').removeClass('d-active');
$('.dropdown-content').slideUp(300).removeClass('d-open');
$(this).addClass('d-active');
console.log($(currentAttrValue));
//THIS LINE FAILS
$(currentAttrValue).slideDown(300).addClass('d-open');
}
e.preventDefault();
});
I've registered the elements with the class dropdown-title using $(document).on(...) but I can't figure out what I need to do to register the elements with the custom ID's. I've tried putting the event callback inside the .each functions, I've tried making custom events to trigger, but none of them will get the 2nd to last line of code to trigger. There's no errors in the console, and when I console log the selector I get this:
[ul#m0.sub-menu.dropdown-content, context: document, selector: "#m0"]
0
:
ul#m0.sub-menu.dropdown-content
context
:
document
length
:
1
selector
:
"#m0"
proto
:
Object[0]
So jQuery knows the element is there, I just can't figure out how to register it...or maybe it's something I'm not thinking of, I don't know.
If you are creating your elements dynamically, you should be assigning the .on 'click' after creating those elements. Just declare the 'on click' callback code you posted after adding the ids and classes instead of when the page loads, so it gets attached to the elements with .dropdown-title class.
Check this jsFiddle: https://jsfiddle.net/6zayouxc/
EDIT: Your edited JS code works... There also might be some problem with your HTML or CSS, are you hiding your submenus? Make sure you are not making them transparent.
You're trying to call a function for a attribute, instead of the element. You probably want $(this).slideDown(300).addClass('d-active'); (also then you don't need $(this).addClass('d-active'); before)
Inside submenus.each loop add your callback listener.
As you are adding the class dropdown-title dynamically, it was not available at dom loading time, that is why event listener was not attached with those elemnts.
var menuCount = 0;
var contentCount = 0;
//find the mobile menu items
var submenus = $('[title="submenu"]');
if (submenus.length && submenus.parent('.fusion-mobile-nav-item')) {
console.log(submenus);
submenus.addClass('dropdown-title').append('<i id="dropdown-angle" class="fa fa-angle-down" aria-hidden="true"></i>');
submenus.each(function() {
$(this).attr("href", "#m" + menuCount++);
// add callback here
$(this).click( function(e) {
var currentAttrValue = $(this).attr('href');
if ($(e.target).is('.d-active') || $(e.target).parent('.dropdown-title').is('.d-active')) {
$(this).removeClass('d-active');
$(currentAttrValue).slideUp(300).removeClass('d-open');
} else {
$('.dropdown-title').removeClass('d-active');
$('.dropdown-content').slideUp(300).removeClass('d-open');
$(this).addClass('d-active');
console.log($(currentAttrValue));
$(currentAttrValue).slideDown(300).addClass('d-active');
}
e.preventDefault();
});
})
var content = submenus.parent().find('ul.sub-menu');
content.addClass('dropdown-content');
content.each(function() {
$(this).attr("id", "m" + contentCount++);
})
}
Turns out my problem is that jQuery is adding to both the mobile menu and the desktop menu, where the desktop menu is being loaded first when I search for that ID that's the one that jQuery finds. So it turns out I was completely wrong about my suspicions.
Is it possible to have a bootstrap (v3) popovers to have it's div loaded right at the start of pageload and not be destroyed when it is being toggled?
I have a popover content in a div:
<div id="popoverContent">
<h1>Stuff</h1>
<p>I'm in a popover!</p>
</div>
And a button that toggles the popover:
<a id="floating_tab" data-toggle="popover" data-placement="left">Button</a>
Here is my Javascript code that handles the button pushes:
<script>
var x = false;
$('[data-toggle=popover]').popover({
content: $('#popoverContent').html(),
html: true
}).click(function() {
if (x) {
$(this).popover('hide');
x = false;
}
else {
$(this).popover('show');
x = true;
}
});
</script>
The thing is, that when $(this).popover('show'); is called, a div is created. Something like this shows up in the inspect element (chrome):
<div class="popover fade left in" role="tooltip" id="popover460185" style="top: 430.5px; left: 2234px; display: block;"><div class="arrow" style="top: 50%;"></div><h3 class="popover-title" style="display: none;"></h3><div class="popover-content">
<h1>Stuff</h1>
<p>I'm in a popover!</p>
</div></div>
But when the button is clicked again, the whole div itself is removed and obliterated from the page.
Is it possible to have the popover div to be created during pageload (hidden though) and can be toggleable without having the div to be deleted?
As stated in the comments, it is not presently possible with Bootstrap 3. The Popover (which is an extension of the Tooltip) is dynamically created on show and detached (using jQuery.detach) from the DOM on hide.
It is probably best to roll your own JavaScript and simply utilize Bootstrap's CSS. However, you could easily patch the functionality using the Popover's event API -the following can be used as a starting place:
$(function () {
var content = $('#popover-content'), // Pre defined popover content.
popover = $('#popover-anchor').popover();
popover.on('inserted.bs.popover', function () {
var instance = $(this).data('bs.popover');
// Replace the popover's content element with the 'content' element
instance.$tip = content;
});
popover.on('shown.bs.popover', function () {
var instance = $(this).data('bs.popover');
// Remove the reference to 'content', so that it is not detached on hide
instance.$tip = null;
});
popover.on('hide.bs.popover', function () {
// Manually hide the popover, since we removed the reference to 'content'
content.removeClass('in');
content.addClass('out');
});
});

I have a Foundation 5 dropdown on my page, which works fine. However when I submit a form in the dropdown area a new element is added to the top of the page so all the elements are moved down.
After that, all my dropdowns stop to work. (If I skip the adding of the element to the DOM, everything is working fine)
My dropdown:
<div id="file-tab">
<i data-dropdown="shareForm16" aria-controls="shareForm16" aria-expanded="false" class="iconTrigger"></i>
<form data-dropdown-content class="share-form f-dropdown content" aria-hidden="true" tabindex="-1" action="" id="shareForm16">
...
</form>
</div>
I thought I need to rebind the foundation event listeners, but it doesn't work. Maybe I am just doing it wrong.
$('#file-tab').on("submit", 'form.share-form',function(e){
e.preventDefault();
var groupName = $(form.target).find('input[type="text"]').val();
var id = $(e.target).parent().children('input[type="hidden"]').val();
if (groupName) {
$(e.target).trigger('click');
window.currentFTT.share(id ,groupName); // adds the element to the DOM
// my attempt to rebind:
$('#'+e.target.id).foundation({bindings: 'events'});
$('i[aria-controls="'+e.target.id+'"]').foundation({bindings: 'events'});
}
});
Instead of calling foundation for individual elements, make a general call to foundation, passing 'reflow' as a parameter:
$(document).foundation('reflow');
E.g:
$('#file-tab').on("submit", 'form.share-form',function(e){
e.preventDefault();
var groupName = $(form.target).find('input[type="text"]').val();
var id = $(e.target).parent().children('input[type="hidden"]').val();
if (groupName) {
$(e.target).trigger('click');
window.currentFTT.share(id ,groupName); // adds the element to the DOM
// my attempt to rebind:
$(document).foundation('reflow');
}
});
I am using the Javascript below to animate an accordion (it's a slightly modified variant of the one explained here: http://tympanus.net/codrops/2010/04/26/elegant-accordion-with-jquery-and-css3/.
Now I wanted to have the first element to be open on pageload, so I figured I just give it some sort of extra-class via Javascript (and define that .active state via CSS) to have it open up.
This worked, however if I hover over any but the first-element with said .active class, the first element keeps its state, and stays open until I hover over it at least once.
So, what I want is: the first element of my accordion is open and collapses if the user hovers over any of the elements that are not the first. I think I need to add a line in the hover function to either take the class away of the first element or to give the new element the active state, but I don't know how to do it and keep breaking the thing.
<script type="text/javascript">
jQuery(function() {
activeItem = jQuery("#accordion li:first");
jQuery(activeItem).addClass('active');
jQuery('#accordion > li, #accordion > li.heading').hover(
function () {
var jQuerythis = jQuery(this);
jQuerythis.stop().animate({'height':'280px'},500);
jQuery('.heading',jQuerythis).stop(true,true).fadeOut();
jQuery('.bgDescription',jQuerythis).stop(true,true).slideDown(500);
jQuery('.description',jQuerythis).stop(true,true).fadeIn();
},
function () {
var jQuerythis = jQuery(this);
jQuerythis.stop().animate({'height':'40px'},1000);
jQuery('.heading',jQuerythis).stop(true,true).fadeIn();
jQuery('.description',jQuerythis).stop(true,true).fadeOut(500);
jQuery('.bgDescription',jQuerythis).stop(true,true).slideUp(700);
}
);
});
</script>
Looks like this is happening because each accordion item has its own hover event that takes care of its own animation. You can refactor the code slightly to make this easier to understand and reuse:
var activeItem = jQuery("#accordion li:first");
jQuery('#accordion > li, #accordion > li.heading').hover(
function () { hoverMe(jQuery(this)); },
function () { unhoverMe(jQuery(this)); }
);
//This gets called when cursor hovers over any accordion item
var hoverMe = function(jQuerythis) {
//If the first item is still active
if (activeItem) {
contract(activeItem); //...Shrink it!
activeItem = false;
}
//Expand the accordion item
expand(jQuerythis);
};
//This gets called when cursor moves out of accordion item
var unhoverMe = function(jQuerythis) {
contract(jQuerythis);
};
//I have moved the hover animation out into a separate function, so we can call it on page load
var expand = function(jQuerythis) {
jQuerythis.stop().animate({'height':'280px'},500);
jQuery('.heading',jQuerythis).stop(true,true).fadeOut();
jQuery('.bgDescription',jQuerythis).stop(true,true).slideDown(500);
jQuery('.description',jQuerythis).stop(true,true).fadeIn();
};
//I have moved the unhover animation out into a separate function, so we can contract the first active item from hoverMe()
var contract = function() {
jQuerythis.stop().animate({'height':'40px'},1000);
jQuery('.heading',jQuerythis).stop(true,true).fadeIn();
jQuery('.description',jQuerythis).stop(true,true).fadeOut(500);
jQuery('.bgDescription',jQuerythis).stop(true,true).slideUp(700);
};
//Now expand the first item
expand(activeItem);
I have put together a simplified version demonstrating the logic. Please let me know how you get on.
