How to scroll new page to top on load on click?

I'm using barba.js to fade new pages in. Code must be placed between the barba wrapper div. When I click a link to a new page though, the new page fades in at the same position as the previous page was in. So if the user clicks a link, the new page is loading in near , which I don't want.
How can I get the new page to load in at the top?
I found the answer on stack about scrollRestoration function but I still don't understand how to make this work.
Could somebody help me to compile the js code below, add some css or html to fix this issue?
$(window).scrollTop(0);
if ('scrollRestoration' in history) {
history.scrollRestoration = 'manual';
}
function delay(n) {
n = n || 2000;
return new Promise((done) => {
setTimeout(() => {
done();
}, n);
});
}
function pageTransition() {
var tl = gsap.timeline();
tl.to(".animate-this", {
duration: .2, opacity: 0, delay: 0, y: 30, //scale:0, delay: 0.2,
});
tl.to(".animate-this", {
duration: 0, opacity: 0, delay: 0, scale:0, //scale:0, delay: 0.2,
});
tl.fromTo(".loading-screen", {width: 0, left: 0}, {
duration: 1,
width: "100%",
left: "0%",
ease: "expo.inOut",
delay: 0.3,
});
tl.to("#svg-1", {
duration: 1, opacity: 0, y: 30, stagger: 0.4, delay: 0.2,
});
tl.to(".loading-screen", {
duration: 1,
width: "100%",
left: "100%",
ease: "expo.inOut",
delay: 0, //CHANGE TIME HERE END TRANS
});
tl.set(".loading-screen", { left: "-100%", });
tl.set("#svg-1", { opacity: 1, y: 0 });
}
function contentAnimation() {
var tl = gsap.timeline();
tl.from(".animate-this", { duration: .5, y: 30, opacity: 0, stagger: 0.4, delay: 0.2 });
}
$(function () {
barba.init({
sync: true,
transitions: [
{
async leave(data) {
const done = this.async();
pageTransition();
await delay(2500);
done();
},
async enter(data) {
contentAnimation();
},
async once(data) {
contentAnimation();
},
},
],
});
});
Have a look:

Here also a codepen to check my issue (html,css):
https://codepen.io/cat999/project/editor/AEeEdg

scrollRestoration shouldn't be necessary, this can be done by resetting scroll position during the transition:
tl.fromTo(".loading-screen", {width: 0, left: 0}, {
duration: 1,
width: "100%",
left: "0%",
ease: "expo.inOut",
delay: 0.3,
onComplete: function() {
window.scrollTo(0, 0);
}
});
Working example here: https://codepen.io/durchanek/project/editor/ZWOyjE

This should be what you're looking for:
barba.hooks.enter(() => {
window.scrollTo(0, 0);
});
(can be found in the docs)

jQuery animations step by step

I have a small problem on my jQuery animation.
I want a button which change the width of a div from 100% to 72.5%. Next to this div could be another div which could fill the rest space (width 22.5%, 5% margin)
It could do following things step by step:
Div 1 get a border
div 1 change his width
div 2 get opacity and change his width
Here is my code:
var hidden = true;
function openEditMenu(){
var em = document.getElementById("editMenu");
var rf = document.getElementById("reportField");
if(hidden){
$({alpha:0}).animate({alpha:1}, {
duration: 1500,
step: function(){
rf.style.border ="1px solid rgba(0,0,0,"+this.alpha+")";
}
});
$("#editMenu").css({opacity: 0.0, visibility: "visible"}).animate({opacity: 1.0},1000);
$(em).animate({width: "22.5%"},{ duration: 1000, queue: false });
$(rf).animate({width: "72.5%"},{ duration: 1000, queue: false });
$(rf).animate({marginRight: "5%"},{ duration: 1000, queue: false });
}
else{
$({alpha:1}).animate({alpha:0}, {
duration: 1000,
step: function(){
rf.style.border ="1px solid rgba(0,0,0,"+this.alpha+")";
}
});
$(em).animate({width: "0%"},{ duration: 1000, queue: false });
$(rf).animate({width: "100%"},{ duration: 1000 });
$(rf).animate({marginRight: "0%"},{ duration: 1000, queue: false });
$("#editMenu").css({opacity: 1.0, visibility: "visible"}).animate({opacity: 0.0},1000);
}
hidden = !hidden;
}
Like you can see in the example now everything happens on the same time. But I want that everything works step by step.
var hidden = true;
function openEditMenu() {
var em = document.getElementById("editMenu");
var rf = document.getElementById("reportField");
if (hidden) {
$({
alpha: 0
}).animate({
alpha: 1
}, {
duration: 1500,
step: function() {
rf.style.border = "1px solid rgba(0,0,0," + this.alpha + ")";
}
});
$("#editMenu").css({
opacity: 0.0,
visibility: "visible"
}).animate({
opacity: 1.0
}, 1000);
$(em).animate({
width: "22.5%"
}, {
duration: 1000,
queue: false
});
$(rf).animate({
width: "72.5%"
}, {
duration: 1000,
queue: false
});
$(rf).animate({
marginRight: "5%"
}, {
duration: 1000,
queue: false
});
} else {
$({
alpha: 1
}).animate({
alpha: 0
}, {
duration: 1000,
step: function() {
rf.style.border = "1px solid rgba(0,0,0," + this.alpha + ")";
}
});
$(em).animate({
width: "0%"
}, {
duration: 1000,
queue: false
});
$(rf).animate({
width: "100%"
}, {
duration: 1000
});
$(rf).animate({
marginRight: "0%"
}, {
duration: 1000,
queue: false
});
$("#editMenu").css({
opacity: 1.0,
visibility: "visible"
}).animate({
opacity: 0.0
}, 1000);
}
hidden = !hidden;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div style="display:inline-flex;width:100%;">
<div id="reportField" style="width:100%; height:50px; background-color:blue;">
a
</div>
<div id="editMenu" style="width:0%; height:50px; background-color:red; visibility: hidden;">
b
</div>
</div>
<button onclick="openEditMenu()">
</button>
I know this solution:
$('#id').animate(
{ left: new value },
duration, function() {
// Animation complete.
});
But it doesnt works on my alpha animation.

jQuery: Call and Uncall a Function

I am using the following code to call a function when the screen is less than 200 but I can't disable the function when the scroll is more than 200.
function animateHeader() {
$(selector)
.animate({ opacity: 0.0, bottom: 70 }, { duration: 600 })
.animate({ opacity: 0.0, bottom: 50 }, { duration: 0 })
.animate({ opacity: 0.0, bottom: 70 }, { duration: 600, complete: animateHeader })
}
$window.on('scroll', function() {
if ($(window).scrollTop() < 200) {
animateHeader();
} else {
// Disable animateHeader()
}
}); // Finish scroll
I know there are alternatives to not call a function here in this case, but is it possible to disable a function when it's already active?

Try using stop() function:
else {
$(selector).stop();
}

Strange jquery animation behavior

The website uses a "black opacity" filter made with this:
/* Body black hover */
$(document).ready(function() {
$("#bg_hover").stop();
$("#bg_hover").animate({ opacity: 0.5 }, 1000);
$("body").hover(function() {
$("#bg_hover").stop();
$("#bg_hover").animate({ opacity: 0.5 }, 1000);
}, function( ) {
$("#bg_hover").stop();
$("#bg_hover").animate({ opacity: 0 }, 1000);
});
});
The problem I have is that I wanted to make a little animation when the user enters to "SOBRE NOSALTRES" (click upper menu to enter the page).
As you can see it animates "well" but not at all, sometimes if you go to "PRODUCTES" and back to "SOBRE NOSALTRES" the animation get's stuck at 98% width. It's kind of strange, why does it happens?
here it's a screenshot of the error:
http://webkunst.comeze.com/test/3.png
and this is the script i'm using to make the animation on NOSALTRES page:
<script>
$(document).ready(function() {
$("#bg_hover").stop();
$("#bg_hover").animate({ width: '80%', opacity: 0.9, left: '10%', right: '10%' }, 800);
$('li#nosaltres').addClass('active')
});
$("body").hover(function() {
$("#bg_hover").stop();
$("#bg_hover").animate({ opacity: 0.9 }, 500);
}, function( ) {
$("#bg_hover").stop();
$("#bg_hover").animate({ opacity: 0 }, 500);
});
</script>

The problem occurs when you hover in the <body> when the PRODUCTES page is loading since you call $("#bg_hover").stop(); in the first line of $("body").hover(function() {}); which stops all animation, including the animation that is reducing the width to 80%.
I can reproduce the problem by clicking on SOBRE NOSALTRES, then moving the mouse to the in and out of the browser window quickly.
I would not add the hover effect to the <body> until the initial resizing to 80% is finished, for example by adding an anonymous function to call once the animation is complete.
$("#bg_hover").stop().animate({ width: '80%', opacity: 0.9, left: '10%', right: '10%' }, 800, function() {
$('li#nosaltres').addClass('active');
$("body").hover(function() {
$("#bg_hover").stop().animate({ opacity: 0.9 }, 500);
}, function( ) {
$("#bg_hover").stop().animate({ opacity: 0 }, 500);
});
});

Dont split it into two lines:\
$("#bg_hover").stop();
$("#bg_hover").animate({ width: '80%', opacity: 0.9, left: '10%', right: '10%' }, 800);
Instead, use:
$("#bg_hover").stop().animate({ width: '80%', opacity: 0.9, left: '10%', right: '10%' }, 800);

Adding easing to image pan

I am using some JavaScript and jQuery (with the easing plugin) to create a virtual tour; really just a long image that can pan left and right. I have found this which is perfect for the cause: http://jsfiddle.net/MvRdD/1/. Is there a way to add easing to the animation?

http://jsfiddle.net/ARTsinn/MvRdD/890/
$(document).ready(function() {
$.getScript("https://raw.github.com/danro/easing-js/master/easing.min.js");
var animateTime = 10,
offsetStep = 5,
scrollWrapper = $('#wrap');
//event handling for buttons "left", "right"
var aktiv;
$('.bttL, .bttR').mousedown(function(e) {
if (e.target.className === 'bttR') {
aktiv = window.setInterval(function() {
scrollWrapper.animate({
scrollLeft: '+=' + 20
}, {
duration: 600,
queue: false,
easing: 'easeOutCirc'
});
}, 10);
} else if (e.target.className === 'bttL') {
aktiv = window.setInterval(function() {
scrollWrapper.animate({
scrollLeft: '-=' + 20
}, {
duration: 1200,
queue: false,
easing: 'easeOutCirc'
});
}, 10);
}
}).mouseup(function() {
window.clearInterval(aktiv);
});
scrollWrapper.mousedown(function(event) {
$(this).data('down', true).data('x', event.clientX).data('scrollLeft', this.scrollLeft);
return false;
}).mouseup(function(event) {
$(this).data('down', false);
}).mousemove(function(event) {
if ($(this).data('down')) {
$(this).stop(false, true).animate({
scrollLeft: $(this).data('scrollLeft') + ($(this).data('x') - event.clientX) * 2
}, {
duration: 600,
queue: false,
easing: 'easeOutCirc'
});
}
}).mousewheel(function(event, delta) {
$(this).stop(false, true).animate({
scrollLeft: '-=' + delta * 60
}, {
duration: 400,
queue: false,
easing: 'easeOutCirc'
});
event.preventDefault();
}).css({
'overflow': 'hidden',
'cursor': '-moz-grab'
});
});
