There are times when it’s really useful for a webpage to scroll up and down automatically. For instance when showing information on a TV screen you may not want to scroll manually. Using jQuery its possible to have the page automatically scroll down at a set speed then scroll back to the top and repeat.
Demo: https://demos.dcblog.dev/autoscroll/
Download: https://github.com/daveismyname/autoscroll
jQuery must be included before the follow code, this can be placed in a document.ready call or placed in an js file I’m using a file called app.js I have a bunch of placeholder text to beef up the page content so there is something to scroll against:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Auto Scroll with jQuery</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<h1>Auto Scroll with jQuery</h1>

<script data-cfasync="false" src="jquery.js"></script>
<script data-cfasync="false" src="app.js"></script>
</body>
</html>
The important code is inside app.js:
//scroll to bottom
setInterval(function(){
//time to scroll to bottom
$("html, body").animate({ scrollTop: $(document).height() }, 1000);
//scroll to top
setTimeout(function() {
$('html, body').animate({scrollTop:0}, 8000);
},2000);//call every 2000 miliseconds
},2000);//call every 2000 miliseconds
setInterval accepts 2 params the first is a function, the second is a time to repeat. Inside the function a call to animate is made which will animate the body of the page and scroll th the bottom of the document as a speed of 1000 microseconds adjust this to suit your page contents.
Next a setTimeout exists to animate back to the top of the page at a speed of 8000 microseconds.
