I\'m writing a modal popup and I need the browser to jump to the top of the screen when the open modal button is pressed. Is there a way to scroll the browser to the top usi
Pure Javascript solution
theId.onclick = () => window.scrollTo({top: 0})
If you want smooth scrolling
theId.onclick = () => window.scrollTo({ top: 0, behavior: `smooth` })
// When the user scrolls down 20px from the top of the document, show the button
window.onscroll = function() {scrollFunction()};
function scrollFunction() {
if (document.body.scrollTop > 20 || document.documentElement.scrollTop > 20) {
document.getElementById("myBtn").style.display = "block";
} else {
document.getElementById("myBtn").style.display = "none";
}
}
// When the user clicks on the button, scroll to the top of the document
function topFunction() {
$('html, body').animate({scrollTop:0}, 'slow');
}
body {
font-family: Arial, Helvetica, sans-serif;
font-size: 20px;
}
#myBtn {
display: none;
position: fixed;
bottom: 20px;
right: 30px;
z-index: 99;
font-size: 18px;
border: none;
outline: none;
background-color: red;
color: white;
cursor: pointer;
padding: 15px;
border-radius: 4px;
}
#myBtn:hover {
background-color: #555;
}
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
<button onclick="topFunction()" id="myBtn" title="Go to top">Top</button>
<div style="background-color:black;color:white;padding:30px">Scroll Down</div>
<div style="background-color:lightgrey;padding:30px 30px 2500px">This example demonstrates how to create a "scroll to top" button that becomes visible when the user starts to scroll the page.</div>
You could do it without javascript and simply use anchor tags? Then it would be accessible to those js free.
although as you are using modals, I assume you don't care about being js free. ;)
you're using jQuery UI dialog, you could just style the modal to appear with the position fixed in the window so it doesn't pop-up out of view, negating the need to scroll. Other
Without animation, you can use plain JS:
scroll(0,0)
With animation, check Nick's answer.
I know this is old, but for those having problems in Edge:
Plain JS: window.scrollTop=0;
Unfortunately, scroll()
and scrollTo()
throw errors in Edge.
