Use the scrollTop Property
You can use the jQuery animate() method in combination with the scrollTop property to scroll to the top of the web page smoothly with an animation.
Let's try out the following example to understand how it basically works:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>jQuery scrollTop Animation</title>
<style>
.scroll-top{
position: fixed;
bottom: 10px;
right: 10px;
z-index: 99;
}
</style>
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script>
$(document).ready(function(){
$(".scroll-top").click(function() {
$("html, body").animate({
scrollTop: 0
}, "slow");
return false;
});
});
</script>
</head>
<body>
<button type="button" class="scroll-top">Go to Top</button>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit...</p>
</body>
</html>
However, if you simply want to scroll to the top of the page without any animation or jQuery you can use the native JavaScript window.scrollTo(x-coord, y-coord) method, like this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>JavaScript Scroll to Top</title>
<style>
.scroll-top{
position: fixed;
bottom: 10px;
right: 10px;
z-index: 99;
}
</style>
<script>
function goToTop(){
window.scrollTo(0, 0);
}
</script>
</head>
<body>
<button type="button" class="scroll-top" onclick="goToTop();">Go to Top</button>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit...</p>
</body>
</html>
