How do I use throttle with .hover(); jQuery?

I'm trying to find the most concise way to throttle a hover function with jQuery. There are many examples of this but they all seem to not work as intended. For example the use of $.throttle doesn't error but it stops the animation from working altogether. This is the code which I'm trying to throttle:
jQuery(document).ready(function($){
var $navTab = $('.nav-tab-parent');
function moveNavTab(e) {
TweenLite.to($navTab, 0.3, {
css: {
left: e.pageX,
top: e.pageY
}
});
}
$(window).on('mousemove', moveNavTab);
$(".toggle-bars").hover( // this is the .hover() function I need to throttle.
function() {
$(".nav-tab-parent").animate({
opacity: 1
});
$(".nav-tab-parent").delay(10).animate({
width: "36px",
easing: "swing"
});
$(".nav-tab").html("MENU");
$(".nav-tab").delay(350).animate({
opacity: 1
});
}, function() {
$(".nav-tab").animate({
opacity: 0
});
$(".nav-tab-parent").delay(150).animate({
width: "0",
opacity: 0,
easing: "swing"
});
}
);
});
I must be missing something here but can't figure it out. Any help in achieving this would be greatly appreciated!

Changed to use entirely GSAP and relying on .timescale() see the documentation — didn't know the underlying structure so will need some configuring but the basis is there. GSAP has a crazy deep documentation but should be familiar enough to jquery with object animations.
var tl = gsap.timeline().timeScale(-1);
tl.fromTo(".nav-tab-parent", {
autoAlpha: 0,
duration: 1
}, {
autoAlpha: 1,
duration: 1
});
$(".toggle-bars").hover(function() {
tl.timeScale(1);
}, function() {
tl.timeScale(-1);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="toggle-bars">.toggle-bars
<div class="nav-tab-parent">.nav-tab-parent</div>
</div>

I suppose you are trying to achieve something like this. You could try to use .stop() method - it will stop current animation and after that you can run next one. Try to play with arguments to choose what best will suit your case.
let $hover = $('.hover-box'),
$target = $('.animated-box');
function show() {
$target.stop(true, true).animate({
opacity: 1,
})
}
function hide() {
$target.stop(true, true).animate({
opacity: 0
})
}
$hover.hover(show, hide)
.hover-box,
.animated-box {
width: 100px;
height: 100px;
border-radius: 8px;
}
.hover-box {
border: 1px solid #ddd;
display: inline-flex;
align-items: center;
justify-content: center;
text-transform: uppercase;
font-family: sans-serif;
cursor: pointer;
margin-bottom: 16px;
}
.hover-box:hover {
background: #ddd;
}
.animated-box {
opacity: 0;
background: gold;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class='hover-box'>Hover</div>
<div class='animated-box'></div>

how to detect if mouseenter or mouseleave

I am trying to achieve an effect of looping through images if a div is hovered or not.
If mouseenter div then cycle through images
if mouseleave div then stop cycling through images and remove all images (only background image will be visible).
currently I am using a setTimeout to fire itself recursively but I am having trouble with jquery on detecting if the mouse is hovering or left the object.
function logoImageLoop() {
$(".one-box .social_gallery .social_img:first").show().next(".social_img").hide().end().appendTo(".one-box .social_gallery");
};
var oneBoxIsHover = false;
$(".one-box").mouseenter(function(){
timeout();
function timeout() {
setTimeout(function(){
logoImageLoop();
timeout();
}, 100);
};
});
Here is a codepen for reference: http://codepen.io/H0BB5/pen/xEpqbv
A similar effect I am trying to achieve can be seen when hovering the cargo logo on this website: http://cargocollective.com/

You just need to clear the timer on mouseleave.
var timer = null;
$(".one-box").mouseenter(function(){
timeout();
function timeout() {
timer = setTimeout(function(){
logoImageLoop();
timeout();
}, 100);
};
}).mouseleave(function(){
clearTimeout(timer);
});
Here's a codepen: http://codepen.io/anon/pen/rrpwYJ

I would use an interval, and the JQuery .hover() functionality. Simply replacing your $(".one-box").mouseenter() with this will run the loop while you're hovered and remove it once your mouse leaves the area.
The important bit:
var imageChangeInterval;
$(".one-box").hover(function() {
imageChangeInterval = setInterval(function() {
logoImageLoop();
}, 100);
}, function() {
clearInterval(imageChangeInterval);
});
Full example:
function logoImageLoop() {
$(".one-box .social_gallery .social_img:first").show().next(".social_img").hide().end().appendTo(".one-box .social_gallery");
};
var oneBoxIsHover = false;
// New code:
var imageChangeInterval;
$(".one-box").hover(function() {
imageChangeInterval = setInterval(function() {
logoImageLoop();
}, 100);
}, function() {
clearInterval(imageChangeInterval);
});

Toggling divs to slide at certain times

Please see this fiddle http://jsfiddle.net/rabelais/6bt70uhj/9/
$('#name-a').click(function() {
$('#bio-line-1').animate({width: 'toggle'});
window.setTimeout(function (){$('#bio-line-2').slideToggle( "slow" ); }, 300);
When clicking the link the first lines slides in from the left, and then when that is finished the second line slides in from the top. When it slides back to be hidden, the first line slides aways before the second line does.
How can I change it so the second line slides away before the first line slides away?

$('#name-a').click(function () {
if ($('#bio-line-1').css('display') == 'none') {
$('#bio-line-1').animate({ width: 'toggle' });
window.setTimeout(function () {
$('#bio-line-2').slideToggle("slow");
}, 300);
}
else {
$('#bio-line-2').slideToggle("slow");
window.setTimeout(function () {
$('#bio-line-1').animate({ width: 'toggle' });
}, 300);
}
});

I think this is what you want:
$('#name-a').click(function () {
window.setTimeout(function () {
$('#bio-line-2').slideToggle("slow", function () {
$('#bio-line-1').animate({
width: 'toggle'
});
});
}, 300);
});
Demo: https://jsfiddle.net/tusharj/6bt70uhj/11/

I think you can do
var $l2 = $('#bio-line-2'),
$l1 = $('#bio-line-1');
var $a = $('#name-a').click(function() {
$a.toggleClass('visible');
var visible = $a.hasClass('visible'),
$f = visible ? $l1 : $l2,
$s = visible ? $l2 : $l1;
$f.animate({
width: 'toggle'
});
window.setTimeout(function() {
$s.slideToggle("slow");
}, 300);
});
#name-a {
left: 38px;
position: fixed;
top: 38px;
z-index: 1;
}
#bio-line-1 {
left: 150px;
position: fixed;
top: 35px;
width: 633px;
z-index: 1;
}
#bio-line-1 p {
color: #333333;
display: block;
float: right;
font-size: 16px;
line-height: 21px;
width: 552px;
}
#bio-line-2 {
left: 150px;
margin-top: 20px;
position: fixed;
top: 38px;
width: 633px;
z-index: 1;
}
#bio-line-2 p {
color: #333333;
display: block;
float: right;
font-size: 16px;
line-height: 21px;
width: 552px;
}
.hidden {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="name-a">
John Love
</div>
<div id="bio-line-1" class="hidden">
<p>holds a Master's Degree from the University of the Arts</p>
</div>
<div id="bio-line-2" class="hidden">
<p>London and currently works in London.</p>
</div>

$('#name-a').click(function() {
if($("#bio-line-2").is(":visible")){
window.setTimeout(function (){
$('#bio-line-1').animate({width: 'toggle'});
}, 300);
$('#bio-line-2').slideToggle( "slow" );
}
else{
window.setTimeout(function (){
$('#bio-line-2').slideToggle( "slow" );
}, 300);
$('#bio-line-1').animate({width: 'toggle'});
}
});

i have made some condition that while showing the lines, line number 1 will appear first and then line number 2 will appear. and while hiding lines, line number 2 will hide first and then line number 1 will hide... i think this is what you trying
Here is fiddle link
Thank You

I'd do something like this. I would also not use a setTimeout as it is not a reliable way to trigger consecutive animations. The timer can trigger at different times depending on what is happening in the UI thread and therefore ruining the effect you are trying to create. You should use the animate success callback of each animation in order to trigger the next one at the exact right time.
http://jsfiddle.net/6bt70uhj/23/
var $line1 = $('#bio-line-1'),
$line2 = $('#bio-line-2');
$('#name-a').click(function() {
if (!$line1.is(":visible")) {
$line1.animate({
width: 'toggle'
}, 300, function () {
$line2.slideToggle("slow");
});
} else {
$line2.slideToggle("slow", function() {
$line1.animate({
width: 'toggle'
});
});
}
});

Animating multiple divs by switching their classes

i am having a hard time trying to animate this box, so the changes go smooth, but i just cannot figure out how to keep everything together. Help would be really appreciated. (already tried with 'switchClass') Here is the whole code:
<script src="jquery.js"></script>
<script src="http://code.jquery.com/ui/1.10.0/jquery-ui.js"></script>
<style>
#box {
position: relative;
margin: auto;
padding: auto;
display: block;
width: 167px;
height: 167px;
}
#box .item {
position: relative;
margin: 0;
display: block;
width: 100%;
height: 33%;
cursor: pointer;
}
#box .over {
height: 84%;
}
#box .other {
height: 8%;
}
#top {
background: red;
}
#mid {
background: green;
}
#bot {
background: blue;
}
</style>
<script>
function anim(item) {
$('.item').attr('class', 'item other');
$('#' + item.id).attr('class', 'item over');
}
function clean() {
$('.item').attr('class', 'item');
}
</script>
<div id='box' onmouseout="clean()">
<div id='top' class='item' onmouseover='anim(this)'></div>
<div id='mid' class='item' onmouseover='anim(this)'></div>
<div id='bot' class='item' onmouseover='anim(this)'></div>
</div>
edit: this code is running just fine, but its just an example of final output (just some animations needed)

Maybe this is not super cool, but seems to do job:
var $items = $('.item').on({
mouseover: function () {
$items.removeClass('over other');
$items.stop().filter(this).animate({height: '84%'}, function () {
$(this).addClass('over');
})
.end().not(this).animate({height: '8%'}, function () {
$(this).addClass('other');
});
},
reset: function() {
$items.removeClass('over other').stop().animate({height: '33%'});
}
});
$('#box').mouseout(function() {
$items.trigger('reset');
});
http://jsfiddle.net/dfsq/4vnkh/1/

If you want to animate the change, please take a look at jQuery animate
Something like this:
$('.item').mouseenter(function() {
$('.item').animate({
height: 80%
}, 500, function() {
// Animation complete.
});
});
$('.item').mouseleave(function() {
$('.item').animate({
height: 33%
}, 500, function() {
// Animation complete.
});
});
in this case you don't need onmouseout or onmouseover

If your animation is based solely on CSS class attributes why not use CSS3 hover pseudo-selector?
Example:
.box {
width: 200px;
}
.box:hover {
width: 400px;
}
<div class="box">Hover over me!</div>
Additional: Response to comments
If you are looking for custom animation duration you can use a callback function with a duration for the initial function call. Here's an example:
$('#div').animate({
width: '200px',
color: 'blue'
}, 5000, function() {
// Animation finished after 5 seconds.
alert("Animation complete!");
});
Addition #2
Your problem child is this little guy:
$('.item').attr('class', 'item other');
This sets each box to 8% height and THEN expands the primary animating box. Remove this and your #box will remain the same height throughout all animations!

How to control animate function on button click?

I have two divs named "arrow" and "inner". I am trying to control the animate slide function when the div is clicked but have been unfortunate. The issue is noticeable when clicking very fast on the "arrow" div after user stops clicking the div is still sliding. I set the animate function under a small delay but I still experience lag. Here is my example code:
<script language="javascript" src="http://code.jquery.com/jquery-1.5.2.js"></script>
<script language="javascript">
$(document).ready(function() {
var out = 0;
$("#arrow").click(function(){
if(out==0)
{
$("#inner").animate({marginRight: "0px"}, 500 );
out=1;
}
else
{
$("#inner").delay(400).animate({marginRight: "-100px"}, 500 );
out=0;
}
});
});
</script>
<div style="background-color: rgb(204, 204, 204); height: 300px; width: 300px; overflow: hidden; position: relative;">
<div id="inner" style="height: 100px; width: 150px; background-color: rgb(0, 204, 102); float: right; margin-right:-150px;" >Form is here</div>
<div id="arrow" style="height: 100px; width: 50px; background-color: rgb(255, 0, 0); float: right; cursor: pointer; position: absolute; top: 0; right: 0;" >Arrow is here</div>
</div>

Just change your code
$("#inner").animate({marginRight: "0px"}, 500 );
to
$("#inner").stop(true, true).animate({marginRight: "0px"}, 500 );
and
$("#inner").animate({marginRight: "-100px"}, 500 );
to
$("#inner").stop(true, true).animate({marginRight: "-100px"}, 500 );
Please see following Link for example : http://jsfiddle.net/UAYTw/1/
you can also use $("#inner").stop(true, false).animate() instead of $("#inner").stop(true, true).animate(). as per your choice.

Using Ravi's code props to him - toggle is cleaner in my opinion
DEMO
$(document).ready(function() {
$("#arrow").toggle(
function(){
$("#inner").stop(true, true).animate({marginRight: "0px"}, 500 );
},
function(){
$("#inner").stop(true, true).animate({marginRight: "-100px"}, 500 );
}
);
});

You can use .animate().stop() method to stop the animation.
Demo: http://jsfiddle.net/YKn7c/

this may help:
$("#button").hover(
function () {
$("#effect").stop().animate({ opacity: '1', height: '130' }, 300);
},
function () {
$("#effect").stop().animate({ opacity: '0', height: '130' }, 300);
}
);
