Using jQuery to trigger CSS shake animation, works every OTHER time ... why?

I have a rather simple fiddle here: http://jsfiddle.net/7aotzqmL/2/ that is supposed to shake a div with CSS animation upon clicking a link. It works, but only every other time (every second time). I'm stumped - can anybody help?
Other answers I've looked at mentioned how when using onmouseover you also need to attach onmouseout... but this is just a click so I'm not sure that's relevant. I just want the div to shake on every click rather than every other.
jsFiddle: https://jsfiddle.net/7aotzqmL/2/
CSS code:
$(function() {
$('a').click(function(ev) {
$('div').toggleClass('shaker');
ev.preventDefault();
});
});
div.shaker {
animation: shake 0.3s;
/* When the animation is finished, start again */
animation-iteration-count: 1; //single shake
}
#keyframes shake {
0% {
transform: translate(1px, 1px) rotate(0deg);
}
10% {
transform: translate(-1px, -2px) rotate(-1deg);
}
20% {
transform: translate(-3px, 0px) rotate(1deg);
}
30% {
transform: translate(3px, 2px) rotate(0deg);
}
40% {
transform: translate(1px, -1px) rotate(1deg);
}
50% {
transform: translate(-1px, 2px) rotate(-1deg);
}
60% {
transform: translate(-3px, 1px) rotate(0deg);
}
70% {
transform: translate(3px, 1px) rotate(-1deg);
}
80% {
transform: translate(-1px, -1px) rotate(1deg);
}
90% {
transform: translate(1px, 2px) rotate(0deg);
}
100% {
transform: translate(1px, -2px) rotate(-1deg);
}
}

<div>shake</div>

Try this will work
$(function(){
$('a').click(function(ev){
$('div').addClass('shaker');
setTimeout(function(){
$('div').removeClass('shaker');
},300);
ev.preventDefault();
});
});
Below code is removing class on even time click, and you animation working on adding class
$('div').toggleClass('shaker');
in above solution, div class will be removed after 0.3secs animation, it will add 'shaker' class every time you click and animation will happen

You are toggling the class so the first click adds it and the second removes it. Instead you could add the class on click and set a single use event listener to listen for the animation end and then remove the class.
$(function() {
const div = $('.container')
$('a').click(function(ev) {
div.addClass('shaker')
div.one('animationend', () => {
div.removeClass('shaker')
})
ev.preventDefault();
});
});
.container {
opacity: 1;
width: 100px;
height: 100px;
background: red;
}
.container.shaker {
/* Start the shake animation and make the animation last for 0.5 seconds */
animation: shake 0.3s;
/* When the animation is finished, start again */
animation-iteration-count: 1; //single shake
}
#keyframes shake {
0% {
transform: translate(1px, 1px) rotate(0deg);
}
10% {
transform: translate(-1px, -2px) rotate(-1deg);
}
20% {
transform: translate(-3px, 0px) rotate(1deg);
}
30% {
transform: translate(3px, 2px) rotate(0deg);
}
40% {
transform: translate(1px, -1px) rotate(1deg);
}
50% {
transform: translate(-1px, 2px) rotate(-1deg);
}
60% {
transform: translate(-3px, 1px) rotate(0deg);
}
70% {
transform: translate(3px, 1px) rotate(-1deg);
}
80% {
transform: translate(-1px, -1px) rotate(1deg);
}
90% {
transform: translate(1px, 2px) rotate(0deg);
}
100% {
transform: translate(1px, -2px) rotate(-1deg);
}
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<div class="container"></div>

Well, for one, you're TOGGLING the class. so one click means "add" the next one means "remove". Also, "preventdefault" should appear first in order to prevent the default behavior of the anchor tag before you try to add or remove classes.
$(function(){
$('a').click(function(ev){
ev.preventDefault();
$('div').addClass('shaker');
setTimeout(()=> {
$('div').removeClass('shaker');
},300)
});
});

$(function(){
$('a').click(function(ev){
$('div').addClass('shaker');
setTimeout(()=>{
$('div').removeClass('shaker');
},300)
ev.preventDefault();
});
});
Use the above code. You were removing the shaker class alternatively.

Fullpage.js onSlideLeave trigger CSS class

How can I trigger CSS class to start my logo animation when scrolling/changing slide with fullpage.js?
I have this (it works alright) for animating my SVG wheel logo:
.logo-img:hover #wheel {
-webkit-animation: in 1s;
transform-origin: 49% 50%;
}
#wheel {
-webkit-animation: out 1s;
transform-origin: 49% 50%;
}
#-webkit-keyframes in {
from { -webkit-transform: rotate(0deg); }
to { -webkit-transform: rotate(360deg);}
}
#-webkit-keyframes out {
0% { -webkit-transform: rotate(360deg); }
100% { -webkit-transform: rotate(0deg); }
}
It's a simple animation of spinning wheel 360deg., now I want it to spin when scrolling and use "in/out" keyframes depending on sliding page up or down.
I'm using fullpage.js and jquery v2.2.4
I hope It makes sense.
Thanks

Use the fullpage.js state classes.
So you can do:
.fp-viewing-section1-slide1 .myItem{
/*Whatever */
}

CSS animation of plane flying onto page and landing

I'm looking for a way to animate a plane flying from off-page onto the page. At the moment, I'm using the code below, which is very clunky and not smooth. Do you know a better way to do this using CSS and HTML? If not, using another method?
.plane-animation{
animation: animationFrames linear 3s;
animation-iteration-count: 1;
transform-origin: 50% 50%;
-webkit-animation: animationFrames linear 3s;
-webkit-animation-iteration-count: 1;
-webkit-transform-origin: 50% 50%;
-moz-animation: animationFrames linear 3s;
-moz-animation-iteration-count: 1;
-moz-transform-origin: 50% 50%;
-o-animation: animationFrames linear 3s;
-o-animation-iteration-count: 1;
-o-transform-origin: 50% 50%;
-ms-animation: animationFrames linear 2s;
-ms-animation-iteration-count: 1;
-ms-transform-origin: 50% 50%;
}
#keyframes animationFrames{
0% {
transform: translate(100%,-20px) rotate(0deg) ;
}
10% {
transform: translate(90%,-30px) rotate(5deg) ;
}
20% {
transform: translate(80%,-40px) rotate(15deg) ;
}
30% {
transform: translate(70%,-50px) rotate(10deg) ;
}
40% {
transform: translate(60%,-60px) rotate(5deg) ;
}
50% {
transform: translate(50%,-70px) rotate(0deg) ;
}
60% {
transform: translate(40%,-60px) rotate(-5deg) ;
}
70% {
transform: translate(30%,-50px) rotate(-10deg) ;
}
80% {
transform: translate(20%,-40px) rotate(-15deg) ;
}
90% {
transform: translate(10%,-30px) rotate(-10deg) ;
}
100% {
transform: translate(0%,0px) rotate(0deg) ;
}

It seems like you're on the right track, and CSS animations should be perfect for the task you're solving. A few quick pointers:
You've made prefixed animation calls like -webkit-, -moz-, -o- and -ms-. However, you've not made any prefixed keyframes. This makes the first part wasted. If you want full browser compatibility you also need prefixed keyframes and prefixed transforms.
Like this:
#keyframes animationFrames{
0% {
transform: translate(100%,-20px) rotate(0deg) ;
}
100% {
transform: translate(100%,-20px) rotate(0deg) ;
}
}
#-webkit-keyframes animationFrames{
0% {
-webkit-transform: translate(100%,-20px) rotate(0deg) ;
}
100% {
-webkit-transform: translate(100%,-20px) rotate(0deg) ;
}
}
....
and so on.
The other part is more esthetic, but I suggest trying to work on one property at a time. Try drawing your animation in lines on a piece of paper first, figure out the axis and vectors that it's moving on and code one at a time. I'm afraid no-one on here can give you a finished piece of code, but with enough practice, I'm sure you will get the hang of animating.

CSS animation NOT executing in Mozilla using mozAnimationName

<style>
#keyframes shake {
0% {
-moz-transform:scale(0);opacity:0;
}
25% {
-moz-transform:scale(1.3);opacity:1;
}
50% {
-moz-transform:scale(0.7);opacity:1;
}
75% {
-moz-transform:scale(2);opacity:1;
}
100% {
-moz-transform:scale(1);opacity:1;-moz-transform:rotate(45deg);
}
}
</style>
<div style="-moz-animation-duration:2s;" onclick='this.style.mozAnimationName="shake";'>TEST</div>
It works fine in Google Chrome with its respective -webkit prefix, but with Firefox (-moz), it doesn't function properly.
Is there a solution for this, or is this simply a dumb mistake on my part? Furthermore, I do not want to utilize jQuery for my solution.

It doesn't work because Firefox no longer requires the vendor prefixes in more recent versions (starting from Firefox 16), so just drop those:
http://jsfiddle.net/nsca73oo/2/
<style>
#keyframes shake {
0% {
transform: scale(0);
opacity:0;
}
25% {
transform: scale(1.3);
opacity: 1;
}
50% {
transform: scale(0.7);
opacity: 1;
}
75% {
transform: scale(2);
opacity: 1;
}
100% {
transform: scale(1);
opacity: 1;
transform: rotate(45deg);
}
}
</style>
<div style="animation-duration: 2s;" onclick='this.style.animationName = "shake";'>TEST</div>

Show loading spinner before heavy processing in jQuery Mobile 1.1?

I'm going mad trying to get a spinner to appear. I've bound my heavy processing function to a button thus:
$(document).delegate("#clearread", "tap", onClearRead);
So on tap it calls this:
var onClearRead = function() {
setTimeout($.mobile.showPageLoadingMsg, 5);
// Civilised cleaning of saved status
var jStorIndex = $.jStorage.index();
for (var i = 0; i < jStorIndex.length; i++) {
if( jStorIndex[i] != "version" ) {
$.jStorage.deleteKey(jStorIndex[i]);
}
}
// Load articles afresh
loadArticles();
$.mobile.changePage("#choosearticle");
} //onClearRead
I find that the spinner does not appear during the clearing/loading of articles (about 10 secs) but only for a brief period while the #choosearticle page loads (0.5 secs).
What am I doing wrong?
I have the spinner working elsewhere in the app.
Thanks

Try this:
$(document).delegate("#clearread", "tap", onClearRead);
var onClearRead = function() {
$.mobile.showPageLoadingMsg();
setTimeout(function(){
//Your heavy processing
$.mobile.changePage("#choosearticle");
}, 5);
} //onClearRead

jQuery.show( [duration ] [, complete ] )
Putting the heavy processing in the "complete" function slot, ensures the object (with show called on it) is visible before the show happens.
