Jquery slidetoggle code to vanilla Javascript that ahndle multiple elements toggle

I have few elements I need to slide, but I don't want to attach whole jQ lib. I like jQ a lot, but whole lib is just overkill in this example.
How to convert jq slideUp/slideDown/toggle to vanilla JS with support of multiple elements passed to function?
JQ code:
var $context = getContext(context);
$($context).on('click', '.menu', function () {
$('.nav').slideToggle();
});
JS code:
var list = document.getElementsByClassName("class1", "class2", "class3");
//or
var list = document.querySelectorAll("class1", "class2", "class3");
var slideUp = function(targets, duration){
// execution
};
slideUp(list, 500);
SO wizards make it happen! :)

I wasn't happy with the last solution I gave you it was rushed and buggy totally unacceptable, Hope you can forgive me...so this is a better version with the clicks of each item working too
const clicker = document.getElementsByClassName("clicker")[0];
clicker.addEventListener("click", function() {
process(document.querySelectorAll(".js-toggle"));
});
[...document.querySelectorAll(".js-toggle")].forEach((element) =>
element.addEventListener("click", function() {
process(this)
})
)
const container = [];
function process(linkToggle) {
container.length = 0
if (linkToggle.length > 0) {
for (let i = 0; i < linkToggle.length; i++) {
container.push(
document.getElementById(linkToggle[i].dataset.container))
animate(container[i])
}
} else {
container.push(
document.getElementById(linkToggle.dataset.container))
animate(container[0])
}
}
function animate(element) {
if (!element.classList.contains("active")) {
element.classList.add("active");
element.style.height = "auto";
let height = parseInt(element.clientHeight || 0)
element.style.height = "0px";
setTimeout(function() {
for (let t = 0; t < container.length; t++) {
do {
container[t].style.height =
parseInt(container[t].style.height || height) +
1 + 'px'
} while (parseInt(container[t].style.height || height) < height);
}
}, 0);
} else {
element.style.height = "0px";
element.addEventListener(
"transitionend",
function() {
element.classList.remove("active");
}, {
once: true
}
);
}
}
.clicker {
cursor: pointer;
background: red;

I hope this helps

you could just use css like so ( wasn't sure witch way you wanted to slid but this gives you an idea of how to do it):
var $slider = document.getElementById('slider');
var $toggle = document.getElementById('toggle');
$toggle.addEventListener('click', function() {
var isOpen = $slider.classList.contains('slide-in');
$slider.setAttribute('class', isOpen ? 'slide-out' : 'slide-in');
});
#slider {
position: absolute;
width: 100px;
height: 100px;
background: blue;
transform: translateX(-100%);
-webkit-transform: translateX(-100%);
}
.slide-in {
animation: slide-in 0.5s forwards;
-webkit-animation: slide-in 0.5s forwards;
}
.slide-out {
animation: slide-out 0.5s forwards;
-webkit-animation: slide-out 0.5s forwards;
}
#keyframes slide-in {
100% {
transform: translateX(0%);
}
}
#-webkit-keyframes slide-in {
100% {
-webkit-transform: translateX(0%);
}
}
#keyframes slide-out {
0% {
transform: translateX(0%);
}
100% {
transform: translateX(-100%);
}
}
#-webkit-keyframes slide-out {
0% {
-webkit-transform: translateX(0%);
}
100% {
-webkit-transform: translateX(-100%);
}
}
<div id="slider" class="slide-in">
<ul>
<li>Lorem</li>
<li>Ipsum</li>
<li>Dolor</li>
</ul>
</div>
<button id="toggle" style="position:absolute; top: 120px;">Toggle</button>
I can't take credit for this its lifted from:
CSS 3 slide-in from left transition
I hope this helps

Could you not simply include the css in the page header so wouldn't need to edit any style sheets, well in any case then how about this:
function SlideDown() {
const element = document.getElementById("slider");
let top = 0;
const up = setInterval(MoveDown, 10);
function MoveDown() {
if (top == 50) {
clearInterval(up);
} else {
top++;
element.style.top = top + '%';
}
}
}
function SlideUp() {
const element = document.getElementById("slider");
let top = parseInt(element.style.top);
const down = setInterval(MoveUp, 10);
function MoveUp() {
if (top == -100) {
clearInterval(down);
} else {
top--;
element.style.top = top + '%';
}
}
}
<!DOCTYPE html>
<html>
<body>
<div id="slider" style="position:absolute; top: -100px;">
<ul>
<li>Lorem</li>
<li>Ipsum</li>

Raise ( Reveal ) text from bottom css animation

I was just going through the web and found some cool text animations over here.
so I thought of taking a part of it and extending it.
As I know what to do first I went through the stack to find out whether any question will relate my idea and for my surprise, I had found one that explains what I need but that has not been answered correctly. I guess the main cause was because it was not explained correctly. so I will try my best to explain the idea.
Previously asked question
The Idea.
Let's suppose I have a heading tag that I need to animate. Them main Idea is not to break one same sentence into two instead if you write a heading or paragraph tag the whole thing should animate. I want to lift/reveal/raise the words from where they are in the image (from the line)
I have changed some of the existing code from the source I got. But the text is revealing/raising from the bottom of the whole block. Which I don't want. I want it to raise them from the line at bottom.
The Code:
// Wrap every letter in a span
$('.ml16').each(function() {
$(this).html($(this).text().replace(/([^\x00-\x80]|\w)/g, "<span class='letter'>$&</span>"));
});
anime.timeline({
loop: true
})
.add({
targets: '.ml16 .letter',
translateY: [100, 0],
easing: "easeOutExpo",
duration: 1400,
delay: function(el, i) {
return 30 * i;
}
}).add({
targets: '.ml16',
opacity: 0,
duration: 1000,
easing: "easeOutExpo",
delay: 1000
});
.wrap {
width: 700px;
margin: 100px auto;
}
.ml16 {
color: #402d2d;
padding: 40px 0;
font-weight: 800;
font-size: 2em;
text-transform: uppercase;
letter-spacing: 0.5em;
overflow: hidden;
text-transform: uppercase;
font-family: sans-serif;
}
.ml16 .letter {
display: inline-block;
line-height: 2em;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<div class="wrap">
<h1 class="ml16"><span>Made with love for a testing purpose</span></h1>
</div>
Can someone help me pushing my incomplete idea to a destination?

What you need to do is wrap each word in another span (say, <span class="word"></span>) and set an overflow: hidden to that - see this fiddle: https://jsfiddle.net/w5uz4mex/
This will ensure that each word independently gets 'hidden' as it animates.
// Wrap every word in a span
$('.ml16').each(function() {
let text = $(this).text();
let words = text.split(' ');
// Clear current element
this.innerHTML = '';
// Loop through each word, wrap each letter in a span
for(let word of words) {
let word_split = word.replace(/([^\x00-\x80]|\w)/g, "<span class='letter'>$&</span>");
// Wrap another span around each word, add word to header
this.innerHTML += '<span class="word">' + word_split + '</span>';
}
});
anime.timeline({
loop: true
})
.add({
targets: '.ml16 .letter',
translateY: [100, 0],
easing: "easeOutExpo",
duration: 1400,
delay: function(el, i) {
return 30 * i;
}
}).add({
targets: '.ml16',
opacity: 0,
duration: 1000,
easing: "easeOutExpo",
delay: 1000
});
.wrap {
width: 700px;
margin: 100px auto;
}
.ml16 {
color: #402d2d;
padding: 40px 0;
font-weight: 800;
font-size: 2em;
text-transform: uppercase;
letter-spacing: 0.5em;
overflow: hidden;
text-transform: uppercase;
font-family: sans-serif;
}
.ml16 .word {
display: inline-block;
overflow: hidden;
height: 2em;
margin: 0 0.4em;
}
.ml16 .letter {
display: inline-block;

}

Edit: As a bonus (unrelated) this can be done very simply without jQuery, and instead utilising CSS animations. This also gives you the benefit of very easily being able to add new animations via the CSS, without having to touch the JS. This is just a quick demo, so should be used as a starting point only (i.e. it has not been tested for any production environment).
See below for an example of slideUp, slideDown and zoomIn
/**
* Create new class for sliding text
*
* #params {Element} wrapper - HTML element with text content
*/
class TextSliderUpper {
constructor(wrapper) {
this.wrapper = wrapper;
// Set delay between characters (in ms)
this.delay = 40;
// Wrap content in relevant wrappers
this._wrapContent();
}
_wrapContent() {
let words = this.wrapper.textContent.split(' ');
let delay = 0;
let content = '';
// Loop through each word, wrap each character in a span
words.forEach((word, multiplier) => {
let word_split = word.split(/([^\x00-\x80]|\w)/g);
let word_content = '';
// Look through each letter, add a delay (incremented)
word_split.forEach((char, index) => {
delay += this.delay;
word_content += `<span style="animation-delay: ${delay}ms">${char}</span>`;
});
// Add spacing between words
if (content !== '') content += ' ';
// Add wrapped words to content
content += `<span>${word_content}</span>`;
})
// Add content to wrapper
this.wrapper.innerHTML = content;
}
init() {
this.wrapper.classList.add('show');
}
}
// Get a list of all headers
let headers = document.querySelectorAll('[data-animate]');
// Loop through, add relevant class
Array.from(headers).forEach(header => {
let slideHeader = new TextSliderUpper(header);
// Allow for delays? Sure!
let delay = header.dataset.delay || 0;
// Delay class (if necessary)
setTimeout(() => {
slideHeader.init();
}, delay)
})

jQuery response() function doesn't return any results because of the variable scope

The problem I encountered is I can't get any results from the jQuery UI Autocomplete form because of the variable scope. Let me show you.
// TAKE A CLOSE LOOK AT THIS METHOD
select: function(e, ui) {
$('#instant-search').text(ui.item.label);
$("#search").autocomplete("option", "source",
function(request, response) {
getAutocompleteResults(function(d) {
// DOESN'T WORK response(d);
});
// WORKS BUT IT SHOULD BE A DYNAMIC ARRAY FROM THE "D" OBJECT
// response(["anarchism", "anarchist black cross", "black rose (symbolism)", "communist symbolism", "political symbolism"]);
});
$("#search").autocomplete("search", ui.item.label);
In order to return results I have to use a function response([...]); outside the getAutocompleteResults(function(d) { ... }); function.
However, the source should be dynamic and not like the static array. In other words:
The function response(d); should return an object, which contains a few properties (title, value, extract). I have to access them by using response(d);, however, this function doesn't work inside getAutocompleteResults(function(d) { ... }); function. How can I achieve this?
There is a small snippet of code, however, the main problem is the select method. You can find this in the middle of the whole code block. I commented it out.
$(function() {
$("html").removeClass("no-js");
var autocompleteResults = [{
title: [],
extract: [],
pageId: []
}];
var capitalizeFirstLetter = function(string) {
return string.charAt(0).toUpperCase() + string.slice(1);

EDIT 1
After some changes, the results are shown, however, before the ajax call. How can I use response() only after the ajax was successfully completed (tried using success callback, didn't work :()?
Full project code: https://codepen.io/Kestis500/pen/zRONyw?editors=0010.
Here you can see step by step how it looks like:
How it looks like when you just reloaded the page:
Let's try entering "a":
We've got some results. Ok, let's try to click on the "anarchist symbolism" element:
Results should look like "anarchist symbolism" search. However, it returns the result of the "a" search. What if we pressed "fraktur" element?
Now it shows our previous search "anarchist symbolism" results. However, it should return elements of the "fraktur" search.
EDIT 2
I've fixed many things and removed some really non sense things from my code. However, the situation with the ajax call is still the same.
https://codepen.io/Kestis500/pen/pazppP?editors=0110
Any ideas?
EDIT 3
Fixed ajax lag (now the ajax request will be sent only after the previous ajax call).
https://codepen.io/Kestis500/pen/JpPLON?editors=0110

I had to first fix a few things in your Ajax call. We then collect the results and build an array that should be returned to response(). This will populate the AutoComplete.
First we will examine the HTML. There was some closing tags missing.
HTML
<div class="v-container">
<div class="v-content text-center">
<div class="wikisearch-container">
<div class="input ui-front">
<input type="text" id="search" placeholder="Search...">
<div class="loading">
<div class="lds-eclipse"></div>
</div>
<button class="icon">
<i class="fa fa-search"></i>
</button>
<table>
<tr>
<td class="fa fa-search"></td>
<td id="instant-search" class="three-dots"></td>
</tr>
</table>
</div>
<div class="search-results">
<h4></h4>
<p></p>
<a target="_blank">Click here for more</a>
</div>
</div>
</div>
</div>
You can see the table and it's cells all have the proper closing tags now.
I didn't make any changes to your CSS or Style.

$("<i>", {

"aria-hidden": true
}).appendTo($field1);
$("<div>", {
class: "autocomplete-second-field three-dots"
}).html(item.label).appendTo($wrap);
return $item.appendTo(ul);
};
});
There was a lot of things to fix and improve.
Let's start with the Ajax. You're making a call to a MediaWiki API and expecting some results. When the call would come back, it would generate warnings about pilimit. Digging into the API docs, this is a parameter specific to the pageimages properties call. To fix this, the prop value had to be extracts|pageimages. Now I get a clean set of results.
You can see I broke out the data so that I could more easily make changes and see what parameters I was sending to the API. Nothing wrong with your method, I just find this a lot easier to work with.
This is all happening inside .autocomplete() when we are populating the source. When we use function as a source, it has to follow a few guidelines:
we pass a request and response in
results must be in an array
the array can contain objects, as long as they contain at least { label, value }
our results array must be passed to response function.
A brief example:
$(selector).autocomplete({
source: function(req, resp){
var q = req.term;
// The Request is an object that contains 1 index: term
// request.term will contain the content of our search
var results = [];
// An array to store the results
$.getJSON("myapi.php", {query: q}, function(data){
$.each(data, function(key, val){
// iterate over the result data and populate our result array
results.push({
label: data.name,
value: data.url
});
resp(results);
});
});
}
});
You can sort or filter the results all you like; as long as you pass them to response in the end.
With your focus and select callbacks, you want to return false. This is discussed more here: http://jqueryui.com/autocomplete/#custom-data
We also see a good example of rendering the menu item. I switched over to making jQuery objects versus raw HTML. You do what works best for you.

Hope this helps.

Scrolling with Anchors, Class and jQuery

First: I'm sorry in advance for my english. This is not my first language. :)
The Situation
So, this is the deal: I'm trying to make a single button where the user can click and then it will automatically scroll down to the next DIV. Each DIV's have the class .anchor, and the one that is "selected" have another class called .anchor--selected. When you arrive at the last one, the arrow rotate to 180deg, so the user can see it will go all the way up. Yay! This part is working!
And the great part is: I don't have to give any of my div a name, since I don't know how many there will be.
But, the next part it's kind of tricky... I mean, for someone who doesn't work a lot with jQuery. (I'm learning, slowly, but I'm learning!)
The Problem
Now, when I'm in the middle of the page while scrolling and I decide instead to click, it go all the way up to the page. So, I tried a little something, and it seem to work. But when I'm in the last anchor, and I scroll too much, it giving me this error Uncaught TypeError: Cannot read property 'top' of undefined(…).
The CodePen
So here the link to the not so working anchor button with scrolling.
$(document).ready(function(){
$(".scroll-down-arrow").on("click", function(e) {
e.preventDefault();
var currentAnchor = $(".anchor--selected");;
var nextAnchor = currentAnchor.next(".anchor");
var firstAnchor = $(".anchor").first();
var lastAnchor = $(".anchor").last();
if(currentAnchor.is(lastAnchor)) {
currentAnchor.removeClass("anchor--selected");
firstAnchor.addClass("anchor--selected");
$('html, body').stop().animate({scrollTop:firstAnchor.offset().top});
$(this).removeClass("prev").addClass("next");
} else {
currentAnchor.removeClass("anchor--selected");
nextAnchor.addClass("anchor--selected");
$('html, body').stop().animate({scrollTop:nextAnchor.offset().top});
if(currentAnchor.is(lastAnchor.prev())) {
$(this).removeClass("next").addClass("prev");
}
}
});
$(window).on("scroll", function() {
var scrollPos = $(window).scrollTop();
var currentAnchor = $(".anchor--selected");;
var nextAnchor = currentAnchor.next(".anchor");
var prevAnchor = currentAnchor.prev(".anchor");
var firstAnchor = $(".anchor").first();
var lastAnchor = $(".anchor").last();
console.log("scrollPos : " + scrollPos + " currentAnchor : " + nextAnchor.offset().top);
console.log(scrollPos <= nextAnchor.offset().top);
console.log("Current anchor is last? : " + currentAnchor.is(lastAnchor));
if(scrollPos >= nextAnchor.offset().top) {
if(currentAnchor.is(lastAnchor)) {
currentAnchor.removeClass("anchor--selected");
prevAnchor.addClass("anchor--selected");
$(".scroll-down-arrow").removeClass("prev").addClass("next");
} else {

nextAnchor.addClass("anchor--selected");
if(currentAnchor.is(firstAnchor)) {

Conclusion
So, I've tried to reuse my code on the "scroll click" and put it on the "window scroll". But I think I'm missing something and I would like some help to get throught it.
Thank you very much and feel free to ask questions! :)

Since you aren't testing to see if there is another .anchor, jQuery is throwing an error. Just test to see if there is a next .anchor.

Note: This doesn't work when scrolling up, I will attempt to fix that.

How do I re-trigger a WebKit CSS animation via JavaScript?

So, I've got this -webkit-animation rule:
#-webkit-keyframes shake {
0% {
left: 0;
}
25% {
left: 12px;
}
50% {
left: 0;
}
75% {
left: -12px;
}
100% {
left:0;
}
}
And some CSS defining some of the animation rules on my box:
#box{
-webkit-animation-duration: .02s;
-webkit-animation-iteration-count: 10;
-webkit-animation-timing-function: linear;
}
I can shake the #box like this:
document.getElementById("box").style.webkitAnimationName = "shake";
But I can't shake it again later.
This only shakes the box once:
someElem.onclick = function(){
document.getElementById("box").style.webkitAnimationName = "shake";
}
How can I re-trigger a CSS animation via JavaScript without using timeouts or multiple animations?

I found the answer based on the source code and examples at the CSS3 transition tests github page.
Basically, CSS animations have an animationEnd event that is fired when the animation completes.
For webkit browsers this event is named “webkitAnimationEnd”. So, in order to reset an animation after it has been called you need to add an event-listener to the element for the animationEnd event.
In plain vanilla javascript:
var element = document.getElementById('box');
element.addEventListener('webkitAnimationEnd', function(){
this.style.webkitAnimationName = '';
}, false);
document.getElementById('button').onclick = function(){
element.style.webkitAnimationName = 'shake';
// you'll probably want to preventDefault here.
};
and with jQuery:
var $element = $('#box').bind('webkitAnimationEnd', function(){
this.style.webkitAnimationName = '';
});
$('#button').click(function(){
$element.css('webkitAnimationName', 'shake');
// you'll probably want to preventDefault here.
});
The source code for CSS3 transition tests (mentioned above) has the following support object which may be helpful for cross-browser CSS transitions, transforms, and animations.
Here is the support code (re-formatted):
var css3AnimationSupport = (function(){
var div = document.createElement('div'),
divStyle = div.style,
// you'll probably be better off using a `switch` instead of theses ternary ops
support = {
transition:
divStyle.MozTransition === ''? {name: 'MozTransition' , end: 'transitionend'} :
// Will ms add a prefix to the transitionend event?
(divStyle.MsTransition === ''? {name: 'MsTransition' , end: 'msTransitionend'} :
(divStyle.WebkitTransition === ''? {name: 'WebkitTransition', end: 'webkitTransitionEnd'} :
(divStyle.OTransition === ''? {name: 'OTransition' , end: 'oTransitionEnd'} :
(divStyle.transition === ''? {name: 'transition' , end: 'transitionend'} :
false)))),
transform:
divStyle.MozTransform === '' ? 'MozTransform' :
(divStyle.MsTransform === '' ? 'MsTransform' :
(divStyle.WebkitTransform === '' ? 'WebkitTransform' :
(divStyle.OTransform === '' ? 'OTransform' :
(divStyle.transform === '' ? 'transform' :
false))))
//, animation: ...
};
support.transformProp = support.transform.name.replace(/([A-Z])/g, '-$1').toLowerCase();
return support;
}());
I have not added the code to detect “animation” properties for each browser. I’ve made this answer “community wiki” and leave that to you. :-)

You have to first remove the animation, then add it again. Eg:
document.getElementById("box").style.webkitAnimationName = "";
setTimeout(function ()
{
document.getElementById("box").style.webkitAnimationName = "shake";
}, 0);
To do this without setTimeout remove the animation during onmousedown, and add it during onclick:
someElem.onmousedown = function()
{
document.getElementById("box").style.webkitAnimationName = "";
}
someElem.onclick = function()
{
document.getElementById("box").style.webkitAnimationName = "shake";
}

Following the suggestion from https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Animations/Tips, remove and then add the animation class, using requestAnimationFrame to ensure that the rendering engine processes both changes. I think this is cleaner than using setTimeout, and handles replaying an animation before the previous play has completed.
$('#shake-the-box').click(function(){
$('#box').removeClass("trigger");
window.requestAnimationFrame(function(time) {
window.requestAnimationFrame(function(time) {
$('#box').addClass("trigger");
});
});
});

A simple but effective alternative:
HTML:
<div id="box"></div>
<button id="shake-the-box">Shake it!</button>​
css:
#box{
background: blue;
margin:30px;
height:50px;
width:50px;
position:relative;
-moz-animation:shake .2s 0 linear 1;
-webkit-animation:shake .2s 0 linear 1;
}
#box.trigger{
display:table;
}
#-webkit-keyframes shake {
0% {
left: 0;
}
25% {
left: 12px;
}
50% {
left: 0;
}
75% {
left: -12px;
}
100% {
left:0;
}
}
#-moz-keyframes shake {
0% {
left: 0;
}
25% {
left: 12px;
}
50% {
left: 0;
}
75% {
left: -12px;
}
100% {
left:0;
}
}​
jQuery:
$('#shake-the-box').click(function(){
$('#box').toggleClass('trigger');
});​
Demo:

Issues:
I don't know if it works on Firefox, because the animation doesn't seem to work there...

Clone works pretty good on paused Karaoke:
On IE11 had to force a reflow (R. Krupiński's shorter version).
$('#lyrics').text("Why does it hurt when I pee?");
changeLyrics('3s');
function changeLyrics(sec) {
str = 'lyrics '+ sec + ' linear 1';
$('#lyrics').css( 'animation', str);
$('#lyrics').css( 'animation-play-state', 'running' );
$('#lyrics').replaceWith($('#lyrics').clone(true));
}
or you can use the following:
function resetAnimation(elm) {
$('#'+elm).replaceWith($('#'+elm).clone(true));
}

Reset the value first. Use reflow to apply the change without using timeout:
function shake() {
var box = document.getElementById("box");
box.style.animationName = null;
box.offsetHeight; /* trigger reflow */
box.style.animationName = "shake";
}
#keyframes shake {
0% { left: 0; }
25% { left: 12px; }
50% { left: 0; }
75% { left: -12px; }
100% { left: 0; }
}
#box {
position: absolute;
width: 75px; height: 75px;
background-color: black;
animation-duration: .02s;
animation-iteration-count: 10;
animation-timing-function: linear;
}
button {
position: absolute;
top: 100px;
}
<div id="box"></div>
<button onclick="shake()">Shake</button>
In contrast to the accepted answer that recommends animationEnd, this method resets the animation even when it's still in progress. This might be or might be not what you want.
An alternative would be to create a duplicate #keyframes animation and switch between the two:
function shake() {
var box = document.getElementById("box");
if (box.style.animationName === "shake")
box.style.animationName = "shake2";
else
box.style.animationName = "shake";
}
#keyframes shake {
0% { left: 0; }
25% { left: 12px; }
50% { left: 0; }
75% { left: -12px; }
100% { left: 0; }
}
#keyframes shake2 {
0% { left: 0; }
25% { left: 12px; }
50% { left: 0; }
75% { left: -12px; }
100% { left: 0; }
}
#box {
position: absolute;
width: 75px; height: 75px;
background-color: black;
animation-duration: .02s;
animation-iteration-count: 10;
animation-timing-function: linear;
}
button {
position: absolute;
top: 100px;
}
<div id="box"></div>
<button onclick="shake()">Shake</button>

Is there an issue with using setTimeout() to remove the class and then read it 5ms later?
svg.classList.remove('animate');
setTimeout(function() {
svg.classList.add('animate');
}, 10);

With your javascript, you could also add (and then remove) a CSS class in which the animation is declared. See what I mean ?
#cart p.anim {
animation: demo 1s 1; // Fire once the "demo" animation which last 1s
}

1) Add animation name to the #box.trigger in css
#box.trigger{
display:table;
animation:shake .2s 0 linear 1;
-moz-animation:shake .2s 0 linear 1;
-webkit-animation:shake .2s 0 linear 1;
}
2) In java-script you cannot remove the class trigger.
3) Remove the the class name by using setTimeOut method.
$(document).ready(function(){
$('#shake-the-box').click(function(){
$('#box').addClass('trigger');
setTimeout(function(){
$("#box").removeClass("trigger")},500)
});
});
4) Here is the DEMO.
