I\'ve bean searching for this for a few hours now and I have no solution. I want a smooth scroll to the top of the page. I already have smooth scrolling to separate anchors
window.scroll({top: 0, behavior: "smooth"})
Just use this piece of code and it will work perfectly, You can wrap it into a method or event.
Pure Javascript only
var t1 = 0;
window.onscroll = scroll1;
function scroll1() {
var toTop = document.getElementById('toTop');
window.scrollY > 0 ? toTop.style.display = 'Block' : toTop.style.display = 'none';
}
function abcd() {
var y1 = window.scrollY;
y1 = y1 - 1000;
window.scrollTo(0, y1);
if (y1 > 0) {
t1 = setTimeout("abcd()", 100);
} else {
clearTimeout(t1);
}
}
#toTop {
display: block;
position: fixed;
bottom: 20px;
right: 20px;
font-size: 48px;
}
#toTop {
transition: all 0.5s ease 0s;
-moz-transition: all 0.5s ease 0s;
-webkit-transition: all 0.5s ease 0s;
-o-transition: all 0.5s ease 0s;
opacity: 0.5;
display: none;
cursor: pointer;
}
#toTop:hover {
opacity: 1;
}
<p>your text here</p>
<img id="toTop" src="http://via.placeholder.com/50x50" onclick="abcd()" title="Go To Top">
Hmm comment function off for me,
try this
$(document).ready(function(){
$("#top").hide();
$(function toTop() {
$(window).scroll(function () {
if ($(this).scrollTop() > 100) {
$('#top').fadeIn();
} else {
$('#top').fadeOut();
}
});
$('#top').click(function () {
$('body,html').animate({
scrollTop: 0
}, 800);
return false;
});
});
});
#top {
float:right;
width:39px;
margin-top:-35px;
}
#top {
transition: all 0.5s ease 0s;
-moz-transition: all 0.5s ease 0s;
-webkit-transition: all 0.5s ease 0s;
-o-transition: all 0.5s ease 0s;
opacity: 0.5;
display:none;
cursor: pointer;
}
#top:hover {
opacity: 1;
}

<div id="top" onclick="toTop()"><img src="to_top.png" alt="no pic "/> klick to top</div>
Elegant easy solution using jQuery.
<script>
function call() {
var body = $("html, body");
body.stop().animate({scrollTop:0}, 500, 'swing', function() {
});
}
</script>
and in your html :
<div onclick="call()"><img src="../img/arrow-up@2x.png"></div>
Here is my proposal implemented with ES6
const scrollToTop = () => {
const c = document.documentElement.scrollTop || document.body.scrollTop;
if (c > 0) {
window.requestAnimationFrame(scrollToTop);
window.scrollTo(0, c - c / 8);
}
};
scrollToTop();
Tip: for slower motion of the scrolling, increase the hardcoded number 8
. The bigger the number - the smoother/slower the scrolling.
Some time has passed since this was asked.
Now it is possible to not only specify number to window.scroll function, but also pass an object with three properties: top, left and behavior. So if we would like to have a smooth scroll up with native JavaScript, we can now do something like this:
let button = document.querySelector('button-id');
let options = {top: 0, left: 0, behavior: 'smooth'}; // left and top are coordinates
button.addEventListener('click', () => { window.scroll(options) });
