Using Javascript and JQuery to create a filter button

I'm trying to make my button functional on my website but for some reason it isn't working. I have been working on it endlessly and need some outside. If you could help with figuring out what I am doing wrong I would really appreciate it. I am still learning JavaScript and JQuery so all of this is new to me.
HTML Code:
<div id="portfolio">
<div class="container">
<div class="row">
<div class="heading">
<h2>PORTFOLIO</h2>
</div>
<div class="filter">
<ul id="filters">
<li><button class="btn active" data-filter="all">ALL</a></li>
</ul>
</div>
<div class="itemsContainer">
<ul class="items">
<li>
<div class="item" div class="column apps">
<img src="triviastartthumbnail.jpg">
<h4>Movie Trivia App</h4>
<p>This app was created to test users knowledge on how well they know their movies
and actors/actresses</p>
</div>
<ul class="img-list">
<span class="link">
<a href="https://vshorty2003.github.io/movietrivia/"><i class="fa fa-link">
</i></a></span>
<span class="search">
<a href="movietriviaappstart.JPG" figcaption="Movie Trivia App" /><i
class="fa fa-search"></i></a>
</span>
<li class="img-item">
<img class='item-img' src="html5-logo.png" alt="HTML icon" />
</li>
<li class="img-item">
<img class='item-img' src="css-3-logo.png" alt="CSS icon"/>
</li>
<li class="img-item">
<img class='item-img' src="js-icon-26.jpg" alt="JavaScript icon" />
</li>
<li class="img-item">
<img class='item-imgjq' src="jquery-icon-16-revised.png" alt="JQuery icon"/>
</li>
</li>
</ul>
CSS code:
/*for filtered buttons*/
li{
display: inline;
list-style: none;
}
JavaScript code:
$("button").click(function(){
$("button").removeClass("btn active");
$(this).addClass("btn active");
var dataFilter = $(this).data('filter');
if(dataFilter == "all") {
$(".filter ul").show();
}
else
{
$(".filter ul").hide();
$("." + dataFilter).show();
}
});

jQuery get attibutes and values from all elements inside a class

I'm scraping a website where it has the following HTML structure
<div id="list" class="book-list">

<ul class="chapter">

I want to use jQuery to get the links from the divs to get something like this
{
"vol.1 ch.1" : "link/1",
"ch.2" : "link/2"
}
As all the items i want has the class ch sts i wanted to get them with the selector, and trying to use each() but didn't work as it shows nodes...
Here's what how i'm trying:
$d('.ch').map(function(){
console.log('This: href',$(this).attr("href"));
}).get();

It is simpler than you thought. Since you've mentioned that you only want to parse links with ch sts classes, I changed the selector.
var map = {};
$(".ch.sts").each(function() {
map[$(this).text()] = $(this).attr("href");
});
console.log(map);

Get all the Elements with class name.
Get the text value and "href" attribute.
x = document.getElementsByClassName("ch sts");
for(i =0; i<x.length; i++) {
console.log(x[i].text +" "+ x[i].getAttribute("href"));

</a> </li>
</ul>
<!--The main div for carousel-->
<div id="myCarousel" class="carousel horizantal slide" data-interval="false">
<!-- Sliding images statring here -->
<div class="carousel-inner">
<div class="item active">
<div class="carousel-caption">
<h3>test1</h3>

<div class="carousel-caption">
<h3>test5</h3>
</div>
</div>
</div>
<!-- Next / Previous controls here -->
<div> </div>
</div>
</div>
</div>
this code is also added
$(document).ready( function() {
$('#myCarousel').carousel({
interval: 4000
});
var clickEvent = false;
$('#myCarousel').on('click', '.container-tab .nav a', function() {
clickEvent = true;
$('.container-tab .nav li').removeClass('active');
$(this).parent().addClass('active');
}).on('slid.bs.carousel', function(e) {
if(!clickEvent) {
var count = $('.container-tab .nav').children().length -1;
var current = $('.container-tab .nav li.active');
current.removeClass('active').next().addClass('active');
var id = parseInt(current.data('slide-to'));
if(count == id) {
$('.container-tab .nav li').first().addClass('active');
}
}
clickEvent = false;
});
});

change your code as below simply remove class from currently active li and add active class to next li as below
$('#myCarousel').bind('mousewheel', function(e) {
$(this).carousel('next');
var $currentlyactive =$('li.active');
$currentlyactive.removeClass('active');
$currentlyactive.next().addClass('active');
});
Updated
$(document).ready(function() {
$('.carousel').carousel('pause');
});
$('#myCarousel').bind('mousewheel', function(e){$(this).carousel('next');});
$('.tab li').on('click', function(){
$('li.active').removeClass('active');
$(this).addClass('active');
});
this is the code in your html page remove this all carousel related code has been done in custom.js..

siblings() in jQuery is not working

I tried to achieve tabs using jQuery. Making the current tab class active is working, but to make its sibling's class null is not working.
jQuery(document).ready(function() {
jQuery('.container .tab-links a').on('click', function(e) {
var currentAttrValue = jQuery(this).attr('href');
console.log(currentAttrValue);
// jQuery(this).addClass('active').siblings.removeClass('active');
// Show/Hide Tabs
//jQuery(currentAttrValue).show().siblings().hide();
// Change/remove current tab to active
jQuery(this).addClass('active');
jQuery(this).siblings().find('a').removeClass('active');
jQuery('each_tab').not(currentAttrValue).css("display", "none");
jQuery(currentAttrValue).css("display", "block");
e.preventDefault();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<section id="features">
<header>
<div class="features-switcher">
<div class="container">
<ul class="tab-links">
<li>
<a class="active" href="#tab1">
<span>tab one</span>
</a>
</li>
<li>
<a class="" href="#tab2">
<span>tab two</span>
</a>
</li>
<li>
<a class="" href="#tab3">
<span>tab three</span>
</a>
</li>
</ul>
</div>
</div>
<hr>
</header>
<div class="tab-content">
<div id="tab1" class="tab--active">
<section class="container">
<h2> content of tab 1</h2>
<hr>
</section>
</div>
<div id="tab2" class="tab--inactive">
<section class="container">
<h2> content of tab 2</h2>
</section>
</div>
<div id="tab3" class="tab--inactive">
<section class="container">
<h2> content of tab 3</h2>
</section>
</div>
</div>
</section>

The <a> elements in questions have no siblings. The containing <li> elements do.
Target those — and their descendant <a> tags — instead, with:
jQuery(this).parent().siblings('li').find('a').removeClass('active');
Your each_tab query can be replaced with:
jQuery('.tab-content > div').not(currentAttrValue).
hide().
addClass('tab--inactive').
removeClass('tab--active');
jQuery(currentAttrValue).
show().
addClass('tab--active').
removeClass('tab--inactive');

You're selecting the <a> tags, then calling jQuery(this).siblings(). But the <a> tags don't have any siblings; it's their parents (the <li> tags) that have siblings. You should be calling jQuery(this).parent().siblings(), instead.

jQuery emptying wrong div? [duplicate]

This question already has answers here:
How to append one jQuery element already in the DOM to another element?
(5 answers)
Closed 3 months ago.
I've been working on a filter plugin using HTML5's data-* attribute, but jQuery (or something) keeps emptying the wrong div.
Basically I have two divs with different classes. '.gallery-source' is the class of the div with ALL of the content (and the 'display' property is set to 'none' value, so it doesn't show up in the document); while '.gallery' on the first hand is empty but then given the contents of '.gallery-source'.
Once the user has selected options to filter in the dropdowns (an unordered list of items, with links that have data-* values matching some of the contents of '.gallery-source' data-* values), the '.gallery' div is emptied and then each matching content (same data-* values as set in the dropdowns) of '.gallery-source' is appended inside '.gallery'.
The code looks something like this:
// Append everything from .gallery-source to .gallery in order to show ALL work (filters may be applied later)
var gallerySource = $('.works-content .gallery-source').html();
$('.works-content .gallery').html(gallerySource);
// Attribute filtering for all work inside .gallery
$('ul#artist-dropdown li a, ul#technique-dropdown li a, ul#material-dropdown li a').on('click', function() {
// Get selected filter on form
var artistFilterValue = $('.works-content .filter-dropdowns .dropdown-wrapper a.button.artist > span').attr('data-filter-artist');
var techniqueFilterValue = $('.works-content .filter-dropdowns .dropdown-wrapper a.button.technique > span').attr('data-filter-technique');
var materialFilterValue = $('.works-content .filter-dropdowns .dropdown-wrapper a.button.material > span').attr('data-filter-material');
// Empty .gallery in order to fill it later with filtered work
$('.works-content .gallery').empty();
// Get filtered elements and append them to .gallery
$('.single-work[data-artist~="' + artistFilterValue + '"][data-technique~="' + techniqueFilterValue + '"][data-material~="' + materialFilterValue + '"]').each(function(){
$('.works-content .gallery').append($(this));
});
});
The document initially looks like this (both '.gallery' and '.gallery-source' are populated):
<div class="row works-content">
<div class="row">
<div class="small-12 medium-12 large-12 columns filter-dropdowns">

But after selecting an option in one of the filter dropdowns, '.gallery-source' is empty :(
What am I missing here? I think I'm going crazy!
Anyway, any help will be much appreciated.

.append moves the entire node from .gallery-source to .gallery. You want to do this instead:
$(this).clone().appendTo('.works-content .gallery');
You can read about .clone() here.
Here's a jsFiddle demo.

The API docs of empty also say:
... If we had any number of nested elements inside <div class="hello">, they would be removed, too.
So your $('.works-content .gallery').empty() may remove more than you want it to.
